Sweden buys FDI for their Luleå-class.
Some current news (2026-05-26): Sweden just announced that they are buying the FDI as their new Luelå-class frigate.
On the news conference the defence minister of Sweden listed the following subsystems that should be incorporated into the new class.
Trackfire for close in defence. 57mm main gun + 40mm cannon. Aster 30 och CAMM ER. Robot 15 Torped 47 GTX Radar.
From that it is possible to make some educated guesses on the layout of new Luelå-class.
That it got a 57mm main gun is no surprise as that has been the signature weapon for the Swedish navy since the middle of the cold war.
The 40mm cannon will most likely replace the RAM launcher on the Greek Kimon-class. In fact, the Luleå-class will look more like the Kimon-class than the Admiral Ronarc'h-class in that will most likely have 32 VLS cells as the Luleå-class is said to have a mix between Aster 30 and CAMM-ER.
Which probably means (hopefully imho) that the Luleå-class will have 16 or 24 sylver a50 cells for Aster 30 and then either 8 or 16 dedicated CAMM-ER cells similar to how the British does it. While CAMM-ER can technically be launched from Sylver it can't be quad-packed so it doesn't really make sense to use up a single cell for a CAMM-ER missile instead of just using a Aster-30. Adding CAMM-ER quad-packed in their own custom VLS cells makes more sense. So then the maxed out load out would be 24 Aster 30 in 24 Sylver A50 and 32 CAMM-ER in 8 dedicated CAMM cells.
Switching out the Exocet for RBS 15 is no surprise nor is the addition of Torpedo 47 as the ASW-weapon. Both are also fairly simple replacements. Adding Trackfire as the RWS for close in defence, probably with a 20mm gun, also makes sense for a Swedish ship. Plus Trackfire is part of the core of the Loke anti-air/anti-drone defence system so it should mean that the Luleå-class will get a superb drone-defence by pairing the Trackfire and the 40mm Mk4 gun.
The inclusion of GTX radar is a bit interesting and exciting as that seems to refer to the next generation of SAABs Giraffe radar family that is being upgraded to use GPU-processing. Not sure if that is what they really meant or what in the end will actually be installed. But if it is, that will be a first in naval radar systems. Which is a bit cool. (Even if it mean the cost of my next gaming computer will go up even more.)
