Which was just "launched" commercially, and was also in the running for the Finnish corvettes in build (plus replacing the older version on FCAs and in shore batteries; lost out to Israeli next-gen 'Gabriel' though).
Let's look at the detail, as the ER thinking was modified
; meanwhile the Swedish navy has gone over to Mk2 but both the navy and the air force will skip Mk3 (see end comment about the AF):
"Mk3 was a radical redesign resulting in what was basically a completely new missile. Following a four-year test program it was adopted by the German Navy, and shortly after that by the Poles. The Swedish Navy is still soldiering on with the MkII, and would have been happy to adopt the Mk3. However, the Swedish Air Force had other thoughts
, and had a requirement for the weapon to be lighter to allow four missiles to be carried simultaneously by the upcoming 39E Gripen. The result was the RBS15 ‘Next Generation’ (still lacking an official designation, though Mk4 wouldn’t come as a surprise), which is an upgraded Mk3 with a lighter launch weight
, longer range, and generally improved performance. The weapon is contracted for introduction into Swedish service for both the Navy and the Air Force during the next decade"
- now Typhoon has Martel (Martel was dictated by an export customer that deploys it also in their navy)
- the new Gripen, thanks to the modified development path
I mentioned before the quote, despite being at the smaller end in size (amongst modern fighter a/c) will be able to carry 4, easily beating the 3 JSMs carried by Norway's F-35s... Norway had the unique requirement for range, to be able to defend the Norway-Spitzbergen (Svalbard) gap, and that eliminated Gripen simply due to its size (fuel/ range) despite unequalled anti-shipping fire power
... can't remember if Typhoon was even in the running (the Marte story arose later)
