Sweden Leads Revival Of Conventional Submarine Capabilities

After a decline in conventional submarine numbers across northern Europe following the Cold War, new submarines are set to surface in NATO’s northern seas. Sweden is leading the charge with its A26 submarine program, with the first boat expected to be in the water in late 2028 and handed over to the Royal Swedish Navy in 2031. This development marks a significant shift in strategic priorities for NATO’s European navies, which had previously questioned the value of submarines due to high costs. The move is reported by Janes.
