Cruise Missiles for HX

From the outset the Finnish Defence Forces have been stating that they are not replacing a multirole fighter (and thus buying a new one), but instead they are replacing the capabilities of it (and thus buying a new one to provide the same capabilities as the old one). This might look like semantics, but was suddenly brought to the forefront when the RFI for weapons and external sensors was sent out.

Short background: the current Finnish Hornet-fleet sport five different weapon types (plus an internal gun). The AIM-9 Sidewinder (in L- and X-versions) provide short-range air-to-air capability, while the AIM-120C provide medium-range air-to-air capability. With the MLU2 air-to-ground weapons have been brought in as well. The JDAM-series of guidance kits are fitted to ordinary 225, 450, and 900 kg bombs (official designations then being GBU-38, GBU-32, and GBU-31 respectively). These use a combination of internal navigation (INS) and GPS to provide accurate hits on the target. The main problem is that hitting moving targets doesn’t really work, which have prompted the creation of other guidance kits sporting laser guidance in combination with INS and/or GPS. These have however not been acquired by Finland. Also, the range is short, and in practice the fighter has to overfly the target. Still, the JDAM is cheap and reliable, and has proved a favourite in Afghanistan and the Middle East. Time will tell if the recent GPS-jamming incidents will cause issues for weapons which rely on GPS for navigation and/or target acquisition.

A solution to getting more range out of a bomb is to fit it with wings, which leads to the AGM-154 JSOW. The JSOW feature folding wings which deploys after launch, letting the weapon glide towards the target. Three different versions are found, of which two hold submunitions (‘cluster bombs’), while the third is a single BROACH-warhead. The BROACH feature a two-stage warhead where a small(ish) shaped charge first blows a hole in the target, which the main warhead the flies through and detonates on the inside of (see this Australian clip of a live-fire test, the slow-motion entry is found at the 0:54 mark). For improved accuracy the AGM-154C with the BROACH feature an infrared seeker for terminal guidance. In Finnish service the JSOW is something of an enigma, with both the number of weapons and version acquired being unclear to me. I had originally thought the JSOW had been acquired in a very limited number for test and evaluation purposes only in case the JASSM wouldn’t be cleared for export, but during Ruska17 it was mentioned as part of the Finnish arsenal. It seems likely that a small number of AGM-154C JSOW are found as a cheaper mid-range solutions for targets which might be too well-defended for a JDAM-run. The big problem with the JSOW is that as it lacks an engine, its range is highly dependent on the speed and height of the aircraft when launched.

The silver bullet in the Finnish airborne arsenal is the AGM-158 JASSM. The JASSM feature a 450 kg penetrating warhead in the form of the WDU-42/B, and is powered by a small jet engine giving it significantly longer range than the JDAM and JSOW. The cruise missile is stealthy, and navigates by combining GPS and INS during flight, before switching on a IR-seeker for terminal guidance. It is a smart weapon even by modern standards, and dives towards the target at different angles depending on the amount of penetration needed (steeper for harder targets such as bunkers). All this also makes the weapon rather expensive, with the DSCA listing the Finnish request for up to 70 weapons at an estimated value of 255 million USD.

These are the capabilities to be replaced: the ability to shoot down enemy aircraft at different ranges, and to strike hard but not necessarily moving targets at all ranges.

It is important to remember that the weapons work already before release, in that any potential attacker has to calculate with the Finnish Air Force being able to launch a strike taking out key installations such as bridges and command bunkers deep behind enemy lines without ever being close to these. The psychological effect of the nagging knowledge that when getting inside a few hundred kilometers of the frontline you are always under threat should not be underestimated.

The press release on the RFI was rather bland, but Jarmo Huhtanen of Finnish daily Helsingin Sanomat had an interesting interview with engineering brigadier general Kari Renko. Renko dropped a very interesting comment, which will have huge consequences for the HX-program.

We won’t go down the route of starting to develop the integration of machine and weapon. We’re buying missiles, their documentation, transportation containers, training, and so forth.

He also mentions that the weapons and sensors will account for roughly a tenth of the total budget, i.e. in the neighbourhood of 700 million to 1 billion Euros. A second interview with program manager Lauri Puranen (retired FiAF major general) in Finnish paper Talouselämä takes a slightly different view, putting the total weapon cost at 10-20% of the total value, i.e. 700 million to 2 billion Euros, though he notes that there is no idea in buying the whole stock immediately upon ordering the fighters, as the weapons have limited shelf life (this might explain the difference their estimates). This sounds about right for providing a small stock of short- and medium-ranged air-to-air missiles and a few different air-to-ground weapons. A short mention of DSCA cost estimates for similar weapons from recent years.

It must be said that this is a very Finnish way of making defence acquisitions. Buying just behind the cutting edge, at the (hopefully) sweet spot where the R&D work is done and the true costs are known while still modern enough to be considered high-tech. The package above comes in at 1.08 billion Euros and would be something of a bare minimum (e.g. 64 fighters would get an average of 4.7 AMRAAMS each, meaning that after the first wave was launched there wouldn’t be any reloads to talk about). The Finnish order is also likely to be more air-to-air heavy than the mix above would be.

It also means that if Renko (who have his roots in the Air Force) is to be taken literally, the HX-field will be turned upside down.

The air-to-air part is no problem, all contenders have sufficient missiles integrated. Guided bombs are also found, though in most cases not JDAM’s but rather laser or hybrid laser/GPS/INS-guided ones. It is questionable if the JSOW is actually needed as the Goldilock-solution between a guided bomb and a cruise missile, and if it is a priority to be bought at the beginning of the project. In any case, it is fully integrated on the F/A-18E/F Super Hornet, while the Rafale feature the AASM ‘Hammer’-series of modular guidance/propulsion kits which include interesting versions that also exist in the middle ground between guided bombs and ‘true’ missiles.

The big dealbreaker is the cruise missile. If Renko means business, that the HX need to have a long-range cruise missile with a serious penetrating warhead ready by the time it reaches full operational capability in the 2029-2031 time span, two of the top-contenders have a problem at their hands.

The Rafale and the Eurofighter Typhoon both sport the joint-French/English SCALP/Storm Shadow. This is a highly potent weapon in the same class as the JASSM, including a stealthy design, and is combat proven over Iraq, Syria, and Libya. The Rafale already carry the weapon, while the Typhoon is about to get it as part of the P3E upgrade currently underway. As such, both should welcome the news that this is a requirement.

The F/A-18E/F Super Hornet just might get a pass, as it sport the Harpoon-based SLAM-ER with a 360 kg WDU-40/B titanium-reinforced penetrating blast warhead. The SLAM-ER feature many of the same capabilities as the JASSM (though being lighter and shorter-legged), and is the US Navy’s answer to the gap created in their inventory when they dropped out of the JASSM-program. The fighter is also in the process of getting the AGM-158C LRASM, the anti-shipping derivative of the JASSM, which might offer a possibility to fast-track AGM-158A/B integration once complete.

JAS 39C/D Gripen have no long-range ground attack capability. This will be remedied by the upcoming Rb 15F-ER which while developed from the RBS15F anti-ship missile will also have a secondary land-attack capability. However, the weapons main use and roots are shown by the warhead which is a 200 kg blast fragmentation one. Excellent for ships, but despite having delayed fusing options this likely lacks the penetration to be able to take on hardened targets.

The F-35 is the other big question mark, with the JASSM not confirmed for the fighter. It has been cancelled for the Block 4, with one spokeswoman saying they “expect it” in the Block 5 timeframe which “is expected to begin in 2024”. The scope of Block 5 is still undecided, with one aviation journalist describing it’s status as “just a collection of tech that didn’t make the cut for Block 4“. RAF/RN had originally planned for the Storm Shadow to equip their F-35’s, but has since dropped it. As such, the F-35 have no confirmed cruise missile for hardened targets at the moment. The one missile which is confirmed is the JSM, which like the Rb 15F-ER is an anti-ship missile with secondary land-attack capability, and which also feature a 200 kg combined blast and fragmentation warhead. Manufacturing partner Raytheon is happy to call it “the only fifth-generation cruise missile that will be integrated on the F-35”, which is likely more of a marketing line than an indication of the company sitting on information that the JASSM has been cancelled for the F-35.

The answer to the Gripen’s woes would have been the Taurus KEPD 350. The joint Swedish-German missile is carried by German Tornadoes, Spanish EF-18 Hornets, and (soon) South Korean F-15 Eagles. Preliminary flights have been undertaken by the Gripen (and the Eurofighter for Spanish and German needs), but the missile was never integrated on the 39C/D, and it’s future as part of the 39E’s arsenal is still unclear. The Swedish then-government/now-opposition signalled back in 2014 that they “want cruise missiles on the new Gripen”, though it has never been clear whether this means the RBS15F or some heavier land-attack missile. In any case, no firm order for KEPD 350 integration onto the Gripen has been made, and it is difficult to see a Brazilian requirement for it. The KEPD 350 is however actively marketed as an option for the Gripen by Saab.

While Puranen’s cost estimate of the weapon package might be higher than Renko’s, he is of the same opinion when it comes to integration costs.

Our position is that the aircraft suppliers are responsible for the integration of the weapons found in their offers, and that the costs for this are included in the offer.

This leaves Lockheed-Martin and Saab with something of a conundrum. Unless JASSM or another suitable missile is confirmed for integration before 2030 by another paying customer, and unless this confirmation comes before the final offers are made in 2021, the companies will have to include the complete integration costs when calculating their bids to Finland. Obviously the majority of the costs will be funneled back directly to their HX-bid (TANSTAAFL), while the Rafale and the Typhoon will be able to make their offers without this additional cost (or at the very least with a significantly reduced one). It also raises the question which missile they should choose to offer. While there has been much speculation about keeping the JASSM’s, their shelf-life does in fact end about the time the Hornets are withdrawn.

Saab has been marketing a willingness to integrate the JASSM if Finland requests so. However, if they are free to offer the long-range strike option in whichever form they want, doing so by integrating their own Taurus instead of Lockheed-Martin’s JASSM might certainly be tempting, especially as the Taurus offer some unique gimmicks such as the ability to detonate at a specific pre-set floor. Another possible solution which might be tempting for both manufacturers would be to develop penetrating 500-lbs warheads for the JSM and Rb 15F-ER, as this might turn out to be a cheaper solution than integrating a completely new weapon. Still, when it comes to penetrating warheads, mass matters, and it is clear that this would be an inferior solution compared to heavyweights such as the JASSM, Storm Shadow/SCALP, or Taurus.

The New Bug in Town – Navy Fighters Ashore

Carrier-based fighters have traditionally had a hard time keeping up with their land-based counterparts. Carrier operations put greater strains on the aircraft, as the shorter take-off and landing places higher stress on the airframe in general and the landing gear in particular. In the same way, the arrestor and catapult gear adds further weight, while space restrictions usually demand folding wings and other mechanisms to allow it to pass through elevators and occupy a smaller footprint while parked.

However, there are a number of classic designs which have been able to defeat this traditional axiom. These include the F-4 Phantom II (which was produced in a number of non-carrier versions) and the A-4 Skyhawk (one of the few modern carrier-based aircraft small enough to not need wing-folding), and crucially for HX, the F/A-18 Hornet.

The background of the Hornet is well-known, having started it’s life as the YF-17 ‘Cobra’, losing the LWF-competition to the F-16, then being developed further to the F/A-18 for the US Navy VFAX program. Interestingly enough, it was soon clear that F-16 (in early versions) didn’t meet the expectations of all potential customers, and a niche for the twin-engined Hornet could be found. A dedicated land-based version was created in the form of the Northrop F-18L, but in the end it was the baseline carrier-versions which came to score a number of export successes, with seven nations ending up choosing the ‘Bug’ over the competition.

For Finland, in an interesting cross-over of requirement, much of the carrier-specific equipment was actually in line with the requirements placed by the Finnish dispersed operations from road bases. Short runways, rough landings, space restrictions, little support equipment, and limited number of ground crew working on the aircraft are all similarities that make the rugged airframes and landing gears more of a benefit than a nuisance. The end result has been that the Hornet has provided stellar service in Finnish colours, having been able to adapt to Finnish road bases with ease. The use of a carrier-spec hook (not to be confused with the emergency hooks used by land-based fighters) to reduce braking distances has also been a big benefit. Somewhat surprisingly both Dassault and Lockheed-Martin have indicated that they will focus on the baseline Rafale C and F-35A respectively, leaving the Super Hornet the only fighter in the game able to use arrestor wires for breaking on a regular basis.

While all manufacturers have stated that their fighters are able to handle road bases without problems, Super Hornet and the JAS 39E Gripen are the ones with the pedigree to put more credibility behind the claims. Boeing is also the one to have their complete organisation already in place, having established working routines with the Finnish Air Force and local industrial partners as part of current Hornet-operations. When discussing the lack of a visible marketing campaign, this was something drawn upon by Boeing, who explained that they like to work closely with the customer and prove the capabilities of the aircraft directly to them. While this “more doing, less talking” attitude is exactly how any marketing executive would explain a perceived lack of publicity, it should not be ruled out that this actually is what Boeing has been doing, given the close association with Boeing Defence and the Finnish Air Force.

Interestingly, the F/A-18E/F shares around 50-60% of their support and maintenance equipment with the ‘legacy’ Hornets. While part of the equipment currently in use by the Finnish Air Force is likely starting to show their age and will have to be replaced in any case, this does still leave room for significant savings as well as for the possibility of staggering the procurements of maintenance equipment. Not having to buy a complete set of tools on day one is not only nice for the initial buy, but also means that throughout the lifespan of the aircraft instances of massed obsolescences amongst the support equipment should be rarer, smoothing out the operating costs during the life cycle. There’s also no need for major investment in fixed infrastructure (such as electrical systems or air supplies), as all Finnish air bases are equipped for handling the F/A-18C/D. As Boeing’s Bryan Crutchfield put it, “If a Hornet flies there today, a Super Hornet can fly there tomorrow”. This has also been practiced by the US Navy, which during carrier operations on occasion has swapped out Hornet-squadrons for Super Hornet ones at short notice (though granted the US Navy does have maintenance equipment for both ‘legacy’ and Super Hornets on their carriers).

Life-cycle costs are something that Boeing likes to talk about. To win the Finnish order the Super Hornet, like the Hornet before it, would have to defeat lighter fighters which have lower flyaway unit costs. The Super Hornet currently has the lowest cost per flight hour for all US tactical aircraft, including the F-16. While the comparison is somewhat skewed to the benefit of the Super Hornet as the Super Hornet fleet generally is the youngest of the active US fighters (with the exception of the F-35), it is still remarkable for a twin-engined naval fighter to top the list. Add in the savings in infrastructure and maintenance, and the life-cycle cost for a Finnish Super Hornet might be very competitive.

The synergies doesn’t stop there, as there is also a clear benefit when it comes to transferring pilots and ground crew from the F/A-18C/D to the F/A-18E/F. Making current Finnish Air Force personnel dual-qualified could be handled in a matter of weeks, and all training could take place in Finland. This is not only a question of transferring the people serving in 2025 when the first HX-fighters are slated to arrive in Finland, but “the Finnish Air Force will have a two aircraft fleet for a number of years”, as Bryan Crutchfield notes. In practice, the current Hornets and their replacement could serve side-by-side for up to five years, if the Air Force decides to maintain the Hornets until HX reaches full operational capability around 2030. This was also the case with the Hornet, where the first F/A-18D and C were delivered to the Finnish Air Force in 1995 and 1996 respectively, with the Draken finally being withdrawn in 2000 (the MiG-21 having left service two years earlier). As such, the argument about ease of transitioning from the Hornet to Super Hornet deserves more credibility than it has usually received, with the benefits tapering off towards 2030 and not 2025 as usually argued.

Of the eight countries which bought the ‘legacy’ Hornet, two already operate the Super Hornet (USA and Australia), two are likely going to operate it (Kuwait and Canada), with Switzerland, Spain and the minor operator Malaysia not looking like likely Super Hornet buyers. This leaves Finland, and many of the arguments which made us choose the Hornet are still perfectly valid today. However, where the F/A-18C Hornet armed with the AIM-120 AMRAAM was clearly the most advanced of the fighters being offered, the Super Hornet faces stiffer competition from both sides of the Atlantic. Traditionally, the Finnish Defence Forces have been rather conservative, favouring tried and tested systems before the new and unproven. Time will tell if Boeing can convince the Air Force that taking what has been a very successful concept and cranking up the dials to eleven is the best way forward, or if a more radical change is warranted.

The New Bug in Town – Versions for Finland

One issue that has been open to much speculation is exactly which version(s) of the Super Hornet will be offered to Finland. The answer was simple, with Bryan Crutchfield explaining that it was up to the customer, and: “As a mainly single-seat air force, I would expect Finland to primarily be interested in F/A-18E.” This lead to the natural follow-up question, why the equally mainly single-seat Royal Danish Air Force was offered only the two-seat F/A-18F, a decision which proved to be something of a decisive issue in the Kampfly-program. “Because they only asked for the two-seater,” Bryan explained. On the question of why, he had no direct answer, but this is yet another strange data point in the already rather murky Danish affair.

More interesting then was that Boeing seemed to assume that Finland would be interested in a number of Growlers as well. In the case of the US Navy, roughly 20% of the Super Hornets bought are of the electronic warfare version, meaning that a potential Finnish mix of Super Hornets could be something along the lines of 40 F/A-18E single-seaters, 12 F/A-18F two-seaters, and 12 EA-18G Growlers, for a combined fleet of 64 fighters. When asked about if the ‘full-spec’ Growler is likely to be released for sale to Finland, Crutchfield was careful not to make any promises, noting that any sale would be a government-to-government deal. However, he went on to say that Finland appears to be a “very trusted” partner in Washington, and pointed to JASSM-deal as an indication that if Finland wants the Growler, there likely wouldn’t be any issues.

The Growler in many ways is an unrivalled platform in the electronic warfare role, being able to not only jam and destroy enemy radars and air-defence systems, but also having a significant capability when it comes to intercepting and jamming enemy communications and signals. The latter has made it a valuable resource in the operations against ISIS, and it is safe to assume that if Finland would acquire a handful of dedicated EW-platforms, it would make us a sought after coalition partner in the kind of low-intensity conflicts we have participated in in Afghanistan and Iraq. The question then is largely about the price of acquiring and operating the Growlers, as well as what kind of a loss having only 40 instead of 52 F/A-18E’s would be in the eyes of the Air Force Command. While the size reduction in ‘true’ fighters is significant, the role of the Growlers as force multipliers might provide a huge enough boost for both the Air Force and, crucially, to the ground forces to warrant this. As said, this is not solely a question of providing SEAD, but also of the Growlers being able to increase the fog of war for the enemy at crucial moments.

“Envelop the enemy in the fog of war, sow confusion while providing time and space for one’s own forces. Jam the adversaries’ radars. Disrupt his communications. Induce indecision; make the enemy question his own equipment and make mistakes.”The mission of the Growler as described by the Growler Industry Team

But even without the Growler, the baseline F/A-18E/F is a highly versatile multirole aircraft. “The most capable combat-proven multi-role aircraft”, as Boeing likes to put it (a statement that will upset the French). In addition to ‘normal’ air-to-air and air-to-ground work, the aircraft is able to handle both the maritime strike (Boeing did feature a scale model of a Harpoon anti-ship missile in their stand) as well as SEAD, two missions discussed at length in the Finnish report at the launch of the HX-project. What makes the SEAD-mission possible is the Integrated Defensive Electronic Countermeasures (IDECM)-package, currently in its Block IV state, coupled with the ‘leakage’ of technology developed for the Growler back into the fighter version of the aircraft.

“Physics matter,” Crutchfield sums up the sensor package, and point towards the large nose of the F/A-18E parked behind us during the interview. The nose hoses the AN/APG-79 AESA radar built by Raytheon, and Crutchfield isn’t shy when talking about the capabilities of the radar, stating that it is ‘generations’ in front of the competition, with rolling upgrades being introduced every two years. It should be remembered that the AN/APG-79 did experience some rather significant teething troubles when first introduced into service, though things seems to have gotten better since. One of the key features of the AESA is that it allows the pilot of the F/A-18F to stay fully focused on the air-to-air picture, while the weapon system operator (WSO) in the aft seat works on the air-to-ground view, with both having access to the radar modes they want.

Like the ‘legacy’ Hornet before it, the Super Hornet is qualified for a large number of weapons, including the most recent versions of the venerable AIM-9 Sidewinder, the AGM-88 HARM, and the AIM-120 AMRAAM (these being the AIM-9X, AGM-88E AARGM, and the AIM-120D respectively). On the horizon the SDB-II and the LRASM looms, while more exotic munitions include the Quickstrike-series of air-dropped mines. Which of these would be of interest to the Finnish Air Force is uncertain, but a continued reliance on ever more advanced versions of the AIM-9/-120 combination would be a natural choice for the immediate future. The big deficit is the lack of the very-long range Meteor ramjet-powered missile, which all other HX-contenders are set to have received prior to HX’s IOC date. The US Navy seems content with traditional rocket-powered air-to-air weapons at the moment, and while Finland naturally could pay for Meteor integration on its own, that would still make be a considerable sum. Going for the Super Hornet could then mean having to get closer to the enemy before firing, as there is a significant difference in the size of the no-escape zones of the throttleable ramjet motor compared to traditional rockets.

The New Bug in Town – Back in the Game

When first starting to cover the HX-program, I held the JAS 39E Gripen and F-35A Lightning II as the favourites, with the F/A-18E/F Super Hornet as the potential black horse. Since that, I have questioned the chances of the ‘Super Bug’, mainly based on two different issues.

The first has been the lack of a major road map or upgrade. The first Advanced Super Hornet-concept was displayed already in 2013 with a company-funded prototype. This was then gradually replaced by less ambitious proposals and talk about integrating only some of the features demonstrated by the Advanced Super Hornet. The US Navy, however, didn’t seem too interested in either the 2013 or the 2016 version of the concepts.

The other has been the seemingly low priority given to the Finnish program by Boeing. Compared to the Danish Kampfly-program where Boeing launched a serious marketing effort (and eventually took the whole thing to court), Boeing has been remarkably absent from the public spotlight in Finland.

Both of these changed last week, with the US Navy ordering the Block III-upgrade to the fleet’s F/A-18E/F Super Hornets and EA-18G Growlers, and Boeing making a high-profile appearance at two Finnish air shows in Helsinki on Friday and Seinäjoki on Saturday and Sunday. Not only did Boeing manage to bring two Super Hornets to Finland, but I also got the opportunity to have a chat with senior manager Bryan Crutchfield to get a better picture of the company’s effort to keep their position as Finland’s supplier of fighter aircraft.

The two fighters brought to Finland were a F/A-18F two-seater and a F/A-18E single-seater. While the single-seater was from the distinguished US Navy squadron VFA-143 Pukin’ Dogs of Vietnam MiG-killer fame, it was the two-seater that really got the heads turning. This was nothing less than the brightly-painted CAG-bird of VFA-103 Jolly Rogers, perhaps the most famous naval fighter aircraft in the world. Getting the opportunity to see both the F/A-18E and the F/A-18F in low-level formation was something many Finnish aviation enthusiasts were happy to experience.

Back on the ground, the F/A-18E spent Saturday as a Boeing demonstrator with temporary markings and mock-up conformal fuel tanks, before reverting back to a Block II F/A-18E for Sunday, and continuing on to Pirkkala AFB (Tampere) where they spent the early part of the week offering the Air Force an opportunity to study the aircraft closer. Pirkkala is home to Satakunta Air Command, responsible for the development of tactics and air doctrines as well as handling flight testing and playing a “pivotal role in the development and fielding of new systems”. This is something of a marketing victory for Boeing, as they are the first to offer the Air Force this kind of a chance to get to explore the aircraft on their home turf and according to their own wishes, guided by the company’s own test pilots.

While the Block III might be toned down when it comes to RCS reduction compared to the original Advanced Super Hornet, this is a calculated decision by Boeing. “The Super Hornet Block I reached initial operational capability back in 2001, when stealth was the hot stuff”, Bryan Crutchfield explains. “This means that the aircraft is designed with stealth features, but so are all the other contenders, so that’s nothing special.” Instead, Boeing likes to focus their energy on other measures, such as jamming. According to their view, jamming provides a flexibility that stealth does not, i.e. you are not restricted to a certain waveband, while at the same time avoiding compromises when it comes to aerodynamics and space restrictions. This means that while stealth might hold significant benefits today, the question whether it will in 2050 is far more uncertain given the current development of sensors with the specific goal of countering X-band stealth.

The US Navy also seems to be happy with this dual-pronged approach, as there are currently no plans to let the F-35 replace the Super Hornet. Instead, the two will keep operating side-by-side into the foreseeable future, with the F-35C replacing the ‘legacy’ F/A-18A through D Hornets currently sharing the carrier decks with the Super Hornet. Exactly how long this will last is anyone’s guess, as the US Navy only forecasts around 25 years into the future (contrary to many other air arms), and there’s currently no retirement date set. Boeing, however, expects the Super Hornet to continue in US Navy service to around 2060, in line with (and then some) the plans for HX. In part this is based on a forecasted need for 100+ new Super Hornets being bought by the Navy within then next five years, with these being expected to serve their full lifespan.

What does Block III then hold? The biggest external change is the conformal fuel tanks, which provide added fuel capacity at a lower drag and RCS compared to traditional external fuel tanks, and without occupying hardpoints that could be used for weapons or other pods. However, as is usually the case with these kinds of upgrades, the main changes are on the inside. One major improvement is the increase in bandwidth when transmitting and receiving data to and from other aircraft. This has become an increasingly important issue, as more and more sensor data and imagery are being transmitted between not only fighters, but other friendly units and installations as well.

Another important upgrade is the fitting of an IRST. IR-sensors are nothing new to US Navy fighters, having featured them on a number of occasions throughout history. However, it is only now they really start to come into their own as mature sensor systems. Part of this is because the sensors themselves have matured, but a part also comes from sensor fusion making it easier for the pilot to take in data not coming from the aircraft’s primary sensor.

And speaking of taking in data, a huge improvement is the new large area display replacing the earlier smaller multi-function displays. The display not only means more surface area on which to show information to the pilot, but also makes a higher degree of customisation possible, based on either individual preferences or the type of mission currently being flown. It is as an example possible to now have both the air-to-air and air-to-ground pictures up on the screen at the same time, thanks to the AN/APG-79 AESA radar and the huge screen area available.

The customisation also makes changes to the human-machine interface quicker, a key focus as the increasing number of sensors and data received from other platforms puts ever increasing demands on the pilots to be able to process large amounts of information. Boeing described how they run simulator tests with a group of around sixty active pilots who came in and tested an upcoming update. After having gathered their feedback, Boeing sent them out for lunch, and the software engineers started to make quick changes which allowed for a second run of testing by the same pilots the very same afternoon. Adaptability is the name of Boeing’s game, and they are increasingly moving away from bigger occasional updates to regular smaller ones.

HX Update Q1 2017

As usual, there is a number of recent events concerning the fighters involved in the HX-program as well as the program itself.

The Rafale is currently having its F3R standard being evaluated, which will be fully certified during 2018, and last week Dassault got the order for the follow-on F4 standard. The main focus of the F4 will likely be on upgrades to the software, including the SPECTRA EW-suite, as well as a new short/medium-range air-to-air missiles (or possibly new versions of the current MICA). The F4 is slated to fly by 2023.

Saab got an order for an upgraded version of their RBS15 anti-ship missile, the two versions ordered being a ship-mounted RBS15 Mk3+ and an air-launched RBS 15F-ER (including integration onto the JAS 39E Gripen). The weapon is developed in cooperation with Diehl, and according to Saab it features “improved combat range, an upgraded target seeker, and a lower mass compared to the earlier system. It also has an ability to combat a wide spectrum of naval and land-based targets.”.

The Eurofighter is continuing with both the Phase 2 and Phase 3 Enhancement programs in parallels, with the latest milestone having been a series of flight trials with the Brimstone anti-vehicle missile. The Royal Air Force is keen to keep the current schedule, as the Tornado is soon about to bow out. Currently, this seems to hold, which should mean that any capability gaps are avoided.

The Finnish Defence Forces’ Logistics Command sent out a preliminary RFI for weapons and other external stores for the HX. This is to be followed by a ‘proper’ RFI later this summer, The idea isn’t as far-fetched as it might first seem. The capabilities of the aircrafts are tied to their weaponry (and external stores), the cost of which also makes up a significant part of the whole project. For a fair comparison of how the fighters will perform in Finnish service, the evaluation need to be performed only with the weapons which are likely to be acquired by the Finnish Air Force. E.g. the Eurofighter feature both the ASRAAM and the IRIS-T short-range air-to-air missiles, but no user has adopted both. In other words, the final cost and capability is highly dependent on which weapon is used in the evaluation. The RFI is also set to investigate the integration cost in the cases where an aircraft doesn’t yet have a suitable weapon integrated.

The Finnish Air Force Command (ILMAVE) has confirmed that the possibility of the HX getting an anti-ship capability is being looked into. This is in line with the recent Finnish defence white paper.

The air show-season, also known as ‘summer’ amongst non-avgeeks, is fast approaching. BAE and Saab have confirmed the presence of the Eurofighter and JAS 39C Gripen respectively flying on both Kaivari and Seinäjoki Air Shows, with Boeing/USN having confirmed that the Super Hornet will come to Kaivari. So far Rafale and F-35 is missing from both, though Lockheed-Martin has promised to show up with some kind of a stand.

HX Trumped

The HX-program is moving forward, and several of the programs have seen significant changes, in many cases caused by 1600 Pennsylvania Avenue’s new resident.

F/A-18E/F Super Hornet

Things are looking up for the ‘Rhino’ (or ‘Super Bug’ if you want) for the moment. The Kuwaiti deal is finally looking like it could secure a second export order for the aircraft, and the Canadians seem like they could actually lease or buy  a small amount as a stop-gap to cover for the cancelled F-35 buy. This move has been discussed for years, but in the last year it has moved from speculation to government policy.

But the twist that has caused most buzz is without doubt the announcement that the new US leadership has ordered a review of the carrier-based version of the F-35C against the Advanced Super Hornet concept. While I find it unlikely that the ‘all-inclusive’ most advanced form of the Advanced Super Hornet would be ordered, this review will likely provide an updated concept (with price tags) that can be employed for future (more limited) USN updates as well as for export drives such as the HX.

Boeing, somewhat surprisingly, has kept a low profile in Finland. It remains to be seen if this will change with this summer’s air shows.

F-35 Lightning II

The F-35 has been under quite some pressure following the tweets of President (then elect) Trump, who was happy to trash the cost of the program.

Lockheed Martin quickly recovered their posture (though not their stock price), and explained that they will certainly look into this, and that they have a plan ready to reduce costs further.

Now, it is uncertain to what extent Lockheed Martin and (especially) Trump are honest and to what extent they simply figured out that this theatre is just what they need. It is no secret that the unit price of the F-35 is on a healthy downward trend following the troubled early years of the program. It is also no secret that Lockheed Martin has been pushing for larger block buys, as these would make it possible for the company to achieve higher efficiency in their production lines. This is an excellent opportunity to enlist the support of the White House for the larger block buys, and in the meantime the president can happily boast about getting a better deal by getting the low-rate lots cheaper than his predecessor. Win-win, at least until some troublesome aviation journalists starts looking it…

Regardless of the politics behind it, the F-35A is now officially and for the first time below the 100 million USD threshold. This came as part of the LRIP 10 agreement, and Lockheed Martin indeed thought it prudent to credit ‘President Trump’s personal involvement’ with accelerating the negotiations and sharpening Lockheed-Martin’s focus on driving down the price. Despite the recent issues with the landing gear of the F-35C carrier-based version, the F-35A version is moving forward and meeting milestones according to plan, and the above-mentioned F-35C review against the Advanced Super Hornet will likely result in yet another paper explaining the need for stealth and sensor fusion on the modern battlefield. In other words, the mid- to long-term prospects for the F-35 look good, perhaps even slightly better than they did before Trump got involved.

Eurofighter Typhoon

In January BAE (finally) launched their official Finnish Twitter-account, quite some time after BAE Systems Belgium got theirs. On the whole, BAE has significantly heightened their profile, and isn’t the least bit shy about the fact that they thinks the Typhoon would be the best answer to the needs of the Finnish Air Force.

While BAE still hasn’t explained exactly why they think that’s the case, they have been happy to announce that the acquisition could be funded through the UK Export Finance.

What is often forgotten is that the Typhoon does indeed have an impressive service record in the harsh semi-subarctic climate of the South Atlantic, having been responsible for the air cover of the Falkland Islands since 2009. Of note is that while the aircrews assigned to RAF Mount Pleasant have been rotated, the aircrafts haven’t. The original four aircraft maintained a constant 24/7 QRA flight for over five years, before finally being relieved a while back. Honouring the traditions of the Hal Far Fighter Flight based in Malta during World War 2, the Typhoons wear tailcodes matching the names of the Gladiators of the original flight.

Dassault Rafale

Eight months ago I sat and listened to a presentation by a representative of Dassault, who happily explained the value of the fighter and (almost) all of its subsystems being French. I smiled and nodded politely, thinking to myself that while I understand the value of this from a domestic point of view, I am unsure whether this is a plus or minus in the case of HX. My worry was based on the sometimes volatile state of French politics, especially compared to the relatively stable state of US ones.

Let’s just say I have revised that opinion.

While France certainly has their share of pro-Russian politicians of different colours, Donald Trump has very efficiently demonstrated that the political risks associated with buying French is no larger than buying from the US.

#MAGA.

Saab JAS 39E Gripen

The first flight of the ‘Dash Eight’ prototype is still some time away. Though this was originally slated for Q4 2016, representatives of Saab are adamant that the program as a whole is still on track, and that the delay is due to moving around different parts of the test and development program.

While this might be true, and not flying for the sake of just flying might be the proper decision from a program point of view, this is still something of a PR-loss for Saab, who has been pushing the “on time and budget” narrative. 2017 will be an important year for Saab’s new fighter.

Seinäjoki International Air Show 2017

Contrary to what usually is the case, the Finnish Aeronautical Association’s air show will receive some competition for the Finnish aviation crowds, in that another major air show will take place in Helsinki the day before. Still, the organisers are clear with that they try to get as many HX-competitors attending as possible, and that they hope to see them “both in the air and on the ground“. Last year the JAS 39C Gripen was flying, with the Eurofighter Typhoon being found on static display. Hopefully this year will bring some new players to the Finnish airspace.

 

The Canadian connection – Hornets in need of replacement

In 1980 Canada declared the F/A-18A Hornet the winner of their New Fighter Aircraft program, which meant it would be brought into service as the CF-18 to replace three different fighters as the country’s sole fast jet. In doing so it beat a number of other fighters, crucially the F-16A. It is important to remember that the F-16 back in those days wasn’t a multirole aircraft, but rather a within visual range fighter with a limited secondary ground attack capability. The F/A-18 with its AIM-7 Sparrow medium-range missiles was arguably the more competent aircraft, and one of the main worries of the Canadian air force was Soviet bombers and cruise missiles swooping down over the Arctic. Canada is also a large and sparsely populated country that include large swaths of land were bailing out does not necessarily mean you’re in for a happy landing. This combination of BVR capability, longer range, and twin-engine safety in the end meant that Canada went with the more expensive option of the F/A-18 over the F-16 (it has to be mentioned that the government did claim that the economic incentives was better for the Hornet, making it cheaper for the Canadian economy. However, these kinds of arguments usually have a tendency to depend upon who’s making the calculations).

Thirteen years after Canada received their first F/A-18’s, the first four Hornets for Finland landed at Tampere-Pirkkala. Finland, though markedly smaller than Canada, had a largely similar set of requirements, including cold-weather capability, twin-engine safety, long-range, and focus on the interceptor role. In the end, both Canada and Finland have been very happy members of the Hornet club, but the end of that era looms at the horizon.

Now the alert reader interrupts, if Finland has to replace its Hornets by 2025 due to their lifespan being up, Canada, having bought theirs ten years earlier, by the same logic should have replaced theirs already?

Yes and no. Finland operated the Hornet up until now as a single-role fighter, have placed a higher focus on traditional dogfighting maneuvers, which are extremely taxing on the airframe. In other words, not all flight hours are created equal, and not all aircraft fly the same amount of yearly hours. Also, the Canadian Hornets have been through a number of upgrade programs. Currently they seem to be looking at another set of programs which will take the aircraft up to and past 2025, not bad considering that the original lifespan was envisioned as 20 years (i.e. up to 2002). Canada also did have the replacement figured out, having been a partner of the F-35/JSF program since its beginning, and is currently a Level 3 Partner, i.e. the ‘normal’ level of partnership (only the UK, the Netherlands, and Italy are ranked higher).

Still, the F-35 has been beset by delays, and the project has been something of a hot potato in Canadian politics. The latest major turn was when Justin Trudeau led the Liberal Party to a victory in the federal elections last year, with the party’s position having been that they will ditch the F-35 and instead launch an open tender for a new fighter (with the F-35 being banned from participating). However, Canada have continued to make the required payments to stay a partner in the program while reviewing how the Hornet should be replaced.

Enter July, and amidst it becoming increasingly clear that there is an urgent need to replace, or at least supplement, the Canadian Hornets, the Canadian government launched what can best be described as a non-binding Request for Information. The aircrafts under consideration are the usual suspects: Boeing F/A-18E/F Super Hornet, Dassault Rafale, Eurofighter Typhoon, Lockheed-Martin F-35 (which is back in the running), and Saab JAS 39 Gripen.

Now, the interesting thing here is the schedule, with the answers to the questionnaire having been requested within three weeks (compare to the eight months allocated for the RFI issued by the Finnish HX). The details are rather sketchy, mainly because the questionnaire is “neither a Call for Tenders nor a Request for Proposals”. The background information provided also emphasises that “no procurement decision has been made“ and that “no summary or final report will be issued following the collection of information from industry”. The schedule for replacing the Hornets is literally given as “as soon as possible”, which ought to make things interesting. The whole thing feels like it is done under extreme time pressure.

Interestingly enough, the flight scenarios in the attached file requires the respondent to use “actual aircraft configuration (utilize systems which are operational with Armed Services today only – non-developmental)”. This requirement pans out very differently. While Saab currently is the only one to sport the Meteor operationally, they only operate the 39C Gripen and not the longer-ranged 39E which would add considerably to their odds when flying intercepts far out over the Arctic. On the other hand, the F-35 is currently only operational in the V/STOL F-35B version, and if the Canadians decide to interpret the requirement literally, this is effectively a way to make certain the F-35 is a non-starter without explicitly writing so. Another problem for the F-35A is the bases used in the scenario. As fellow blogger Doug Allen noted over at Best Fighter 4 Canada, the 6,000 feet runways are too short for comfort. The Typhoon in turn is designed for exactly the scenario described in the evaluation, transiting high and fast to meet an enemy aircraft far out, but is a few years from getting an AESA radar and the Meteor. The Rafale does feature supersonic drop tanks and a potent AESA set, but the repeated requests for “seamless” integration with Five Eyes ISTAR and other tactical and strategic assets might not play to its strengths. The weapons are also uniquely French.

Enter the Super Hornet, which features the AN/APG-79 AESA radar, is seamlessly integrated into the US-Canadian NORAD air defence network, and carries the same munitions and missiles that the ‘legacy’ Hornet does. The last part is explicitly asked for in the questionnaire, something which is not the case in any documents regarding the HX which are openly available. The Super Hornet manufacturing line is also struggling with having too few aircraft to produce each year, so quickly ramping up to supply the RCAF with a limited number of stop-gap aircraft would be *relatively* easy. Boeing also has an established partnership with the Canadian defence forces and aviation industry. All in all, the stage seems set for Boeing’s fighter, and Canada is indeed one of the countries for which stealth isn’t necessarily a big deal, at least not for their homeland defence/NORAD contribution. Noteworthy is also that the questionnaire does mention cost for 100 pilots being trained, which would imply that the information could serve as a base for the complete Hornet replacement program (though one should remember that there isn’t a procurement decision for anything as of yet).

Another possibility is that, despite his continued official anti-F-35 view, Trudeau is trying to set the stage for a F-35 purchase, by creating the foundations for a competition, which the F-35 then can sweep clean (compare to Kampfly in Denmark). For Canada, a mix of Super Hornets (or Typhoons) for NORAD duties combined with F-35A’s for expeditionary work under NATO and UN commitments might actually be the ideal solution. Only time will tell if this will be the final outcome.
