The torpedo was classified as obsolete in the 1960s.[2] The Mark 27 was essentially a Mark 24 mine which had been modified for submarine launching in a 21-inch submerged torpedo tube by the addition of 1" wood guide studs mounted on the torpedo's outer shell.[1][4] Modifications and improvements{{Infobox weapon| name = Mark 27 Mod 4 torpedo | image = | caption = | origin = United States | type = Acoustic torpedo[1] | is_ranged = yes | is_explosive = yes | is_missile = yes | service = 1946-1960 | used_by = United States Navy | wars = | designer = Ordnance Research Laboratory, Pennsylvania State University | manufacturer = Avco[1] Naval Ordnance Station Forest Park | design_date = 1946[1] | production_date= 1946-1954[1] | number = 3000[1] | variants = | weight = 1175 pounds[1] | length = 125.75 inches[1] | diameter = 19 inches (with 21-inch guide rails)[1] | range = 6200 yards (12 minutes search duration)[1] | filling = Mk 27 Mod 2, HBX[1] | filling_weight = 128 pounds[1] | detonation = Mk 11 Mod 2 contact exploder | engine = Electric[1] | propellant = | speed = 15.9 knots[1] | guidance = Gyroscope[1] | launch_platform = Submarines[1] }} The Mark 27 Mod 4 torpedo was designed by the Ordnance Research Laboratory of Pennsylvania State University in 1946 as an improved version of the Mark 27 torpedo.[1] Fully compatible with electrical setting fire control systems through the use of the standard 65-pin umbilical cable, this weapon was in service on submarines for about ten years. It was withdrawn from service use in 1960 with the introduction of the Mark 37 torpedo. See also
