US Navy avoided a 2022 ‘trough’ in submarine fleet size, but industry challenges threaten future growth

Defense News – This fiscal year was expected to be the first in which the U.S. Navy dipped into a “trough” in its submarine force, falling below the previous requirement for 48 attack subs and facing two decades of reduced numbers, with as few as 41 at times. Instead, the Navy is holding steady at 50 and plans to only grow the fleet, thanks to efforts to extend the lives of many aging Los Angeles-class SSNs by about three years each and to refuel five of them altogether for additional years of operations.
