V-355 class nuclear fleet submarine
The V-355-class, also called the Barracuda class, were a large series of nuclear fleet submarines and the workhorses of the post-World War silent service. They featured greatly improved quieting, dive depth, sonar, at the cost of a slower speed. They were generally. Their updated fire control systems allowed them to fire a wider variety of weapons and an improved dive-plane design made it possible for them to surface under thin ice. 50 members of the class were commissioned between 1365 and 1372 and replaced many older World-War era fleet boats as they were launched.
Although the navy was considerably outnumbered by the recently formed Aemoric Union in raw submarine numbers, it was counter balanced by vastly more advanced and sophisticated boats they were producing. Dunavaria, the primary military power behind the AU, contributed 600 vessels, whilst East Siegmaria, Wesmere, Saliam and Libeccia contributed another 500. Having more than a three-to-one advantage in numbers by 1386, the Antarans needed to rely on more than just a technological edge, and thus their surface ASW fleet did not slack.
During the Nuclear War, tallies for ASW kills reached 122 vessels by the Barracuda class alone, at a cost of 24 ships from all causes. If other kills are factored in, on average a Barracuda class destroyed 10 vessels of all types before itself sinking. By World War standards, this might've been unimpressive, but the Antaran Navy did not participate signifincantly in merchant raiding unlike the last global conflict. The sinkings were primarily against warships.
