The M74 tank recovery vehicle (M74)[1] was an engineer vehicle used by the U.S. Army in the 1950s. It was designed to cope with the heavier weights of the M26 Pershing and M47 Patton. It could also be suitable for light dozing, since it had a hydraulic, front-mounted spade. 1126[2] were produced by Bowen-McLaughlin-York by converting M4A3 Sherman tanks starting in 1954. From 1956, 60 M32B3A1s were converted by Rock Island Arsenal until 1958.
After the Korean War the M74 was designed to cope with the heavier weights of the new vehicles that were being introduced.[3]
Designed in 1953,[4] it was based on the M4A3 HVSS medium tank and it was developed to cope with the heavier M26 Pershing and M47 Patton tanks which were entering service, which the M32 armoured recovery vehicle (ARV) was unable to retrieve. Using the standard Ford GAA and HVSS suspension the chassis would be rebuilt. It was replaced in service with the U.S. Army by the M88 Hercules.[5]
The M74 was fitted with a main 60000lb[6] hydraulic winch, a lighter-duty general purpose secondary winch, a hydraulic A-frame, and a hydraulic front-mounted spade, which was suitable for light dozing, as well as serving as an anchor for heavy winching operations.[7] [8] It had a .50-caliber M2 machine gun atop the hull and a .30-cal M1919A4 machine gun in the right bow.
The M74B1 was a M32B3 HVSS converted to M74B1.[9]
1126 M74 ARVs were produced between 1953 and 1955 by Bowen-McLaughlin-York. The conversion of M4A3 Sherman tanks into M74 recovery vehicles was started by Bowen in 1954.[10] Some were also converted from obsolete M32A1B3 by Rock Island Arsenal until 1958.
