Why did the US Navy invest in the S-3 Viking and carrier-based ASW aircraft?
Short answerThe aircraft let a carrier group investigate and intercept suspected submarines at long range as part of a layered ASW screen.
NotesThe Viking is compared with the earlier Fairey Gannet in the context of each aircraft's own era. Its operational logic was to push submarine interception and contact investigation as far from the carrier as possible. Combined with escorts, towed arrays, and broader maritime patrol coverage, carrier aircraft formed part of a layered open-ocean surveillance system.
