Under Scottish Skies – The Path Forward

‘Seek and Destroy’. That’s the motto of the RAF’s 41(R) test and evaluation squadron currently residing at RAF Coningsby. Operating six Typhoons (as well as a few Tornados set for retirement next year), the squadron is responsible for testing updates to RAF’s Typhoons and looking into the best ways of employing new capabilities in the field, before these are rolled-out to the frontline squadrons of the service. This summer, the squadron will start testing a new and highly destructive tool, as the first operational Typhoons will receive the P2E-upgrade (Phase 2 Enhancements). The most obvious change to RAF Typhoon operations this brings is the introduction of the Meteor very-long range air-to-air missile, though internally the there will also be major improvements to the data link and sensor fusion.

“Meteor [on Typhoon] will feature a two-way datalink, which is quite different to Rafale”Paul Smith, BAE Systems Test Pilot

Meteor is something both RAF and BAE Systems like to talk about. RAF Lossiemouth station commander group captain Paul Godfrey notes that the real life roll-out has been preceded by a significant amount of test in simulators, focused on looking into the tactics the new weapon will allow for. “I am hugely looking forward to it”, he says. BAE test pilot Paul Smith shows a slide highlighting the different velocity pattern of the ramjet-driven missile compared to traditional rocket-powered ones. Rocket engines accelerate faster out of the gate, but once the rocket has burned out the missile will coast towards the target, meaning that long-range shots will have relatively little energy left for maneuvering close to the target. The Meteor’s ramjet engine is able to cruise at an economical setting and then throttle up when it closes in on the target, giving it a huge boost to the no-escape zone compared to rocket-powered missiles. It is no surprise that the Meteor is set to complement or in some cases replace the AIM-120 AMRAAM and MICA medium- and long-range missiles on all HX-contenders with the exception of the F/A-18E/F Super Hornet, though there are differences to exactly how it is being implemented. Both the Eurofigher and the Gripen will feature a two-way datalink, which allows the missile to send data back to the aircraft, further increasing accuracy as well as situational awareness.

But P2E is only part of what RAF calls the the Centurion staircase, a series of phased enhancements aimed at making sure no capabilities will disappear with the retirement of the Tornado in 2019. The P3E(a) is in the works for RAF, which will bring the Brimstone to the Typhoon. Officially described as a low-collateral high precision air-to-surface weapon, the anti-tank/anti-vehicle missile is probably best described as an AGM-65 Maverick for the 21st century. It has been used with great success in all combat operation RAF has taken part in during recent years. Godfrey highlighted its performance in Libya, where RAF Tornados used it to take out a pro-Gaddafi T-72 which was shooting at a crowd in an urban environment. The Brimstone penetrated the tank, and the explosion was violent enough to cause the turret to bounce from its mount, while the people standing besides it were unhurt. The Brimstone has also quite a lot of potential against lighter naval vessels, and being carried on triple-racks a nice number of missiles can be carried by the Typhoon.

Yes, that is the kind of stuff that gives landing craft skippers nightmares.

The other weapon being integrated with P3E(a) is the Storm Shadow stealthy cruise missile, called SCALP in French service. In the event of the Eurofighter (or Rafale) actually winning the HX-program, this would likely be acquired to replace the AGM-158 JASSM in Finnish service (the 15 year shelf-life of the missiles nicely matches the retirement date of the F/A-18C Hornet). In parallel the P3E(b) is being developed for the Kuwait Air Force, and includes the Enhanced GBU-16 (GBU-48) 1,000 pound laser/GPS-guided bomb, as well as the CAPTOR E AESA radar and the Sniper advanced targeting pod in place of RAF’s Litening III pods.

There has been much talk about the fact that the Eurofighter still relies on the CAPTOR M mechanically scanned radar, which, despite being more or less as good as it gets when it comes to mechanical scanning, is still not an electronically scanned array. Godfrey admits that while the current radar is very good, he would like to get the CAPTOR E.  “Would I like to have an AESA? Sure. Why? Because of versatility.” While his wish will be granted, in the case of RAF, the CAPTOR E is still some time out in the future.

Before HX deliveries the plan is that yet another major upgrade will have taken place. The P4E is currently in the negotiation phase, and as such its exact scope is yet undecided. The plan is that the upgrade will include full operational capability for the CAPTOR E, upgrades to the PIRATE infrared search and track sensor, as well as the integration of SPEAR long-range anti-tank/anti-vehicle weapon (and/or the Small Diameter Bomb in some version). The SPEAR will, together with a planned major improvement to the DASS and sensor integration, be at the core of allowing the Typhoon to take up the SEAD/DEAD mission. This is a most welcome addition for RAF, as they lack a dedicated SAM-hunting capability after the retirement of the ALARM anti-radiation missile in 2013. In addition, a number of anti-ship missiles are currently being evaluated. These include the Marte ER, of which there is currently a feasibility study ongoing for integrating it onto the Typhoon, as well as the JSM and Harpoon (of which the JSM is further along). A contract for the P4E is expected within the next 12 months.

Pair of Tiffies

“The Centurion staircase is what’s driving the UK Typhoon program”JOHN BROMEHEAD, GENERAL MANAGER BAE SYSTEMS

What won’t see a direct replacement is the RAPTOR reconnaissance pod, the British version of the Goodrich DB-110. Instead, advanced targeting pods will take over the role of dedicated reconnaissance pods for the Typhoon.

The P4E would likely form the basis of the Eurofighter Typhoon’s HX-bid. Still, it is important to remember that just because an aircraft is certified for a certain weapon, it does not mean that Finland would get these (case in point the current F/A-18C Hornet is able to carry the better part of the US Navy’s arsenal, while in Finnish service the weapons used goes on the fingers of one hand). In the case of the Eurofighter, while the weapons integration is part of the core package, ‘unlocking’ a certain weapon or capability means buying it from the nation(s) that have originally paid for it’s integration. In this way, costs for popular weapons are brought down through sharing, but you only pay for the ones you plan on buying. Realistically, this means that Finland e.g. would buy either IRIS-T (likely) or the ASRAAM short-ranged air-to-air missiles to complement the longer-ranged Meteor, and not both. In the same way, exactly which ground attack weapons would be bought is open. To replace the capabilities of the current F/A-18C Hornet the Storm Shadow would likely replace the JASSM, with SPEAR and some suitable GPS/LGB being other likely candidates. Brimstone and an anti-ship missile would add significant punch to the Air Force, but while the Air Force Command has confirmed they are looking into the anti-shipping mission for HX, it is unlikely that the funds will be found for these (at least not in the initial buy).

What will then follow after P4E? The Typhoon is set to stay RAF’s primary air superiority fighter for the foreseeable time, and the current plan is that it will stay in RAF service beyond 2050. Integration with unmanned platforms operating is a hot topic. A large area display for the cockpit has also been proposed to customers, but currently the interest from the users has instead focused on the Striker II helmet mounted sight, which will provide a full-colour, fully digital night/day sight. While the exact development path is still open, it is clear that the development will continue. As BAE Systems Mark Parkinson notes: “There is simply nothing else on the horizon.”

Typhoon starting to unlock growth potential

The Eurofighter Typhoon has long been one of the prime contenders for the title of fighter with the most untapped potential. While the combination of excellent fast/high performance, a sizeable radar dish, and a large battery of ASRAAM and AIM-120 AMRAAM missiles have long made certain that it is one of the best BVR interceptors available, the lack of a AESA radar and limited range of ground attack weaponry available have made it seem lackluster when compared with other multirole fighters, and in some aspects even with the very Tornado it is set to replace.

While this comparison is somewhat unjust and oversimplified, it is also true that there has been a marked lack of interest on the part of the governments of Spain, Italy, Germany, and the UK with regards to keeping the Typhoon at the forefront of technology. In a way this is understandable, as all of the air forces operate older types which already largely have the ground attack capabilities that the Typhoon is lacking. Allocating precious funds from limited defence budgets to unlock capabilities that’s already there in another form have been hard to justify. Especially with two of the four air forces already having received their first F-35’s.

But nothing lasts forever, and that include both Tornadoes and Hornets. After having already had to push back on the retirement date for a number of Tornado squadrons, the RAF in particular have finally decided to put some effort into actually unlocking more of the Eurofighter’s potential.

The current situation is that the RAF is operating their Typhoons in the somewhat ungainly named P1E(B)-standard, which is adding on to the original P1E (the first standard to bring multirole capability) by, amongst other things, introducing the very capable Paveway IV guided bomb. The Paveway IV adds a dual GPS/INS-seeker as well as being aerodynamically more efficient compared to earlier members of the Paveway-family, and has rapidly become the RAF’s weapon of choice when requiring more punch than the Brimstone.

The past weeks’ major story has been that the Typhoon has performed at RIAT and Farnborough with the upcoming P3E weapons kit, in a configuration that include:

  • Four Meteor very-long range air-to-air missiles
  • Two ASRAAM mid/long range air-to-air missiles
  • Six Brimstone 2 anti-vehicle/low-collateral damage guided missiles
  • Two Paveway IV guided bombs
  • Two external drop tanks

While a single aircraft might be unlikely to employ both Brimstones and Paveways on the same mission, it does show a well-rounded capability to target many different kinds of air and surface threats. What is even more interesting is that the aircraft flies during the airshows with this loadout, further emphasising the impressive thrust and manoeuvrability available to the Typhoon.

“This display will also demonstrate is that Typhoon, even with this weapons fit, loses none of the incredible agility and manoeuvrability for which it is known.”

Nat Makepeace, BAE Systems Typhoon Experimental Test Pilot

Notable is also the fact that of these weapons, only the Brimstone 2 is actually a P3E weapon, with the Meteor being integrated under the earlier Phase 2 Enhancement (together with the Storm Shadow stealthy cruise missile), and the Paveway IV and ASRAAM being available already today. In an export configuration, the Typhoon also benefits from having already integrated both the long-range ASRAAM and the highly-manoeuvrable IRIS-T (used by non-UK Typhoons), giving it an interesting mix of heat-seeking missiles. In addition the brand new SPEAR missile has also been successfully test-fired earlier this year, and though no decision has yet been taken, integrating it would open up even further capabilities. The only piece of the puzzle currently missing is the CAPTOR-E AESA radar, which is currently about to start flight testing as well under the P3E-program. It seems like the Typhoon finally is starting to show its true multirole potential.
