Saab signs deal worth billions for Swedish subs
At around 1,900 tonnes (surfaced or submerged?) the A26 will be much heavier than Sweden is used to. This would be a large sub to move in the very shallow and narrow waters of its mainly Baltic operating area. The A26's size will improve Sweden's ability to confront Russian forces outside the Baltic - in the North, Norwegian or Barents Seas.
With a large horizontal diver/diver delivery vehicle tube large displacement UUVs (LDUUVs) could be launched to more safely approach the Russian Baltic Fleet's Base at Kaliningrad Oblast (an enclave).
While the two A26s are being built and 2 Gotlands overhauled Sweden will rely on three subs - the two Sodermanlands and the third Gotland class.
