USS Skipjack (SSN-585) and appendage drag can be combined via algebra to show that the vessel should have reached 31 knots submerged. This speed was some 9 knots faster than the "Nautilus" made using the same basic reactor, and only 2 knots shy of the "Albacore"'s best theoretical submerged speed (33 kn). "Skipjack"'s maneuver capabilities, furthermore, added a whole different dimension to ASW problems as she could reverse direction in the distance of her own length, and were referred to as "flying", as "Skipjack" and her sister ships climbed, dove, and banked like an airplane. The antisubmarine warfare (ASW) problems created by such
