TKRB – Coastal Defense in Swedish

In a surprise move, Sweden today announced that they will reintroduce truck-based coastal defense batteries equipped with the Saab RBS15 heavy-anti ship missile. This is not a new system for Sweden, which operated exactly such a unit for five years between 1995 and 2000. This was then rapidly disbanded in the general drawdown of the Swedish Defense Forces. The decision was widely criticised, and has since come to be seen as a major mistake (amongst several that took place between 2000 and 2009). Crucially, the equipment was not stored for a possible reactivation, but dispersed without any kind of central plan. Some of the trucks were sold on the civilian market, some were used by Saab, FMV, or the defense forces themselves.

The original TKRB (Swe. Tung kustrobot, literally ‘Heavy coastal missile’) was the RBS-15KA based on the baseline RBS 15, later referred to as Mk I. The current version in Swedish naval use is the updated Mk II, which also roughly corresponds to the Finnish MTO 85M. This is starting to show its age, and in the Finnish Navy it is to be replaced in both vessel- and coastal-based roles in the time span of 2018 to 2025. A number of countries around the Baltic Sea already operate the upgraded Mk III, which can be considered a completely new weapon for most intents and purposes.

The interesting part is that Sweden at very short notice has decided to introduce a new(ish) weapon system with a very limited operational life span of just five to ten years, after which it will have to be replaced with a new missile. Granted, this is a low-cost solution, with the weapons themselves already found in the inventory and the drawings for the truck-mount probably based on the original implementation. Still, it has been known for years that this system would significantly increase the deterrence factor, and nothing has happened until now.

The fact that this significantly heightens the Swedish Defense Forces ability to defend their home waters is great news for Finland as well, as this is one place where our supply lines would be vulnerable to intercept without the Finnish Navy or Air Force being able to do something. However, this also causes a very uncomfortable question to pop up again:

What does the Swedish Commander-in-Chief know, that our politicians pretend they don’t?
