Американская атомная подводная лодка «Sturgeon» long hull

STURGEON class submarines were built for anti-submarine warfare in the late 1960s and 1970s. Using the same propulsion system as their smaller predecessors of the SSN-585 Skipjack and SSN-594 Permit classes, the larger Sturgeons sacrificed speed for greater combat capabilities. They are equipped to carry the HARPOON missile, the TOMAHAWK cruise missile,and the MK-48 and ADCAP torpedoes. Torpedo tubes are located amidships to accomodate the bow-mounted sonar. The sail-mounted dive planes rotate to a vertical position for breaking through the ice when surfacing in Arctic regions.
Beginning with SSN-678 Archerfish units of this class had a 10-foot longer hull, giving them more living and working space than previous submarines of the Sturgeon Class.
