The torpedoes used Mark 46 silver oxide batteries. These had a known tendency to overheat, occasionally igniting or exploding. Training torpedoes used rechargeable secondary batteries. For a long time, the Mark 37 was a primary U.S. submarine-launched ASW torpedo. It was replaced by the Mark 48 starting in 1972. The remaining inventory was then ...

The Mark 33 was used as the main director on some destroyers and as secondary battery / anti-aircraft director on larger ships (i.e. in the same role as the later Mark 37). The guns controlled by it were typically 5 inch weapons: the 5-inch/25 or 5-inch/38 .
The authors report that concerns were raised in 1967 and 1968 about the Mk 37 torpedo carried aboard Scorpion—before Scorpion left Norfolk for her last mission. The concerns focused on the battery that powered the torpedoes. The battery had a thin metal-foil barrier separating two types of volatile chemicals.
The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. [9] The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology.
The Type 55 designation was given to a lengthened and modified version of the American Mark 37 torpedo manufactured in Japan, which in turn was designated as the Mark 37-0-N (Mark 37 Mod 0, the version without wire guidance). [41] Other variants of the Mark 37 were imported, not manufactured domestically. The Mark 37 remained in service until 1987.
Sargo was charging her oxygen tanks when the oxygen line, which entered the submarine through the stern torpedo room hatch, developed a leak and a fire ignited. Two Mark 37 torpedo warheads detonated "low-order", and the fire spread dramatically, killing the crewman tending the oxygen line, machinist's mate third class James E. Smallwood. The ...
The class was completed with four or five 5-inch (127 mm) dual purpose guns (anti-surface and anti-aircraft (AA)), controlled by a Mark 37 Gun Fire Control System as in the previous Sims class. The introduction of two centerline quintuple torpedo tube mounts in this class was a significant improvement and was continued in subsequent World War ...
