The M32 Armored Recovery Vehicle was an
Horizontal Volute Spring Suspension
(HVSS), which were demarcated by the suffix "A1" after the model number.
M74 Tank Recovery Vehicle in 1954, when heavier tanks were produced, such as the M46 Patton. The M32 had a 30 short tons (27 t) winch, 18 ft (5.5 m) boom, and an A-frame
jib. It was armed with two machine guns and a mortar mainly to provide cover for an emergency retreat.
Specifications
The M32 Tank Recovery Vehicle was an
Continental R975-C1 or -C4 9 cylinder radial gasoline engine, running at 2,400 rpm, the M32B2 model had a General Motors 6046 twin diesel engine; running at 2,100 rpm, and the M32B3 model had a Ford GAA V8 gasoline engine running at 2,600 rpm. The range and fuel capacity likewise varied between 120–150 mi (190–240 km) and 148–175 US gal (560–660 L), respectively, depending on the engine and base vehicle. However, top speed remained constant at 24 mph (39 km/h).[3][4]
It had a Spicer manual
M1919 machine gun. There were 20 hand grenades (Fragmentation Mk.II), and six smoke grenades in the crew compartment. The armament was used only for self-defense, as the vehicle was not designed to be used as an offensive weapon.[4]
Development history
In early 1942, the US Army began mobilizing and reequipping for war in Europe. Based on British combat experience from earlier in the war, the
BARV; however, the Ordnance Department did not wish to use these variants and ordered several new ARV prototypes to be developed, also based on the M4 Sherman.[5]
The basic prototypes of the M32 were built by
Camp Hood, Texas (T5E2), and Camp Seely, California (T5E4) for further testing. However, during the testing, the T5E3's engine was damaged, so it could not go through further. In June 1943, Ordnance Committee Minutes 21553 standardized the designs of the T5, T5E1, T5E2, T5E3, and the T5E4 as the M32, M32E1, M32E2, M32E3, M32E4, respectively. These minutes also terminated the T7 project. The M32E4 did not enter production.[2] Many M32s were later converted into M34 Prime Movers, which were unarmed and fitted with additional equipment used to tow heavy artillery pieces.[6]
Production history
The serial production of the M32 was started by Lima Locomotive Works, which converted five M32B2s in June 1943. They also intermittently produced 26 M32B3s in May 1944, followed by 20 more vehicles in the summer of 1944.
Pressed Steel Car Company produced 163 M32s and 475 M32B1s from December 1943 to December 1944.[2] Pressed Steel Car also converted 298 M4A3 Shermans into M32B3s between May and December 1944. Baldwin Locomotive Works and the Federal Machine and Welder Company were licensed to produce M32 variants in November 1944. Baldwin Locomotive Works produced 195 M32B1s before June 1945 and the latter produced 385 M32B1s before May of that year. In total, 1562 M32s were produced.[2]
Service history
The M32 entered service with the US Army in July 1943. They served in the
M74 Tank Recovery Vehicle replaced the M32B1A1s after the Korean War in 1954[9] after the production of heavier tanks such as the M46 Patton.[10]
Especially during the Korean War, the M32 was considered inadequate for its role as an armored recovery vehicle because the power of the engine was insufficient to pull new, much heavier tanks, such as the M26 Pershing and M46 Patton.[11] Earlier variants' narrow tracks also gave the vehicle insufficient flotation to move over poor terrain such as mud and snow.[citation needed]
Some M32B1s were also shipped to Britain under Lend-Lease, where they were designated the ARV Mark III by the British Army.[12] In 1944, the Ordnance Department experimented with the M26 Pershing-based T12 Armored Recovery Vehicle, but it became too expensive and was never put on the production line.[13] The M32 was also planned to have mine-exploding equipment, such as the T1E1 Earthworm and the T2E1 Mine Exploder. However, only the T1E1 had any service with the vehicle.[14]
Several M32s were loaned to the
M51 Super Shermans.[15] Several M32s saw service in the Mexican Army under the nickname "Chenca" until 1998. The U.S. loaned Mexico these M32s shortly after World War II.[16] Some M32 and M32Bs were also sent to Tito's Yugoslavia during the Informbiro period.[17]
Variants
- M32 – The original version, based on the M4 Sherman. 163 were produced by Pressed Steel Car in 1944.[18]
- M32B1 – A M32 based on the M4A1. 1,085 were produced by Federal Machine, Baldwin Locomotive, and Pressed Steel Car.[18] Some were also shipped to Britain under Lend-Lease. It was named ARV Mark III by the British Army.[12]
- M32B2 – A M32 based on the M4A2. 26 were produced by Lima Locomotive.[18]
- M32B3 – A M32 based on the M4A3. 344 were produced by Lima Locomotive and Pressed Steel Car.[18]
- M32B4 – A M32 based on the M4A4. Never entered production.[18] Had a Chrysler Multibank engine.[4]
- M32A1 – A M32 with HVSS suspension.[18]
- M32A1B1 – A M32B1 with HVSS suspension. 175 were converted by Baldwin Locomotive.[18]
- M32A1B2 – A M32B2 with HVSS suspension.[18]
- M32A1B3 – A M32B3 with HVSS suspension.[18]
- M34 Prime Mover – M34 Prime Movers were simply M32B1 Recovery Vehicles without the towing cable and were just used for pulling towed artillery into place.[19] It was typically reserved for pulling heavy artillery, such as the 240 mm howitzer.[20] It lacked any armament and had four seats for crew. The vehicle also had tail lights, electric outlets for stopping of towed loads, and multiple stowage ports.[6] Production started in 1944 and ended in 1945.[12]
Additional equipment
- T1E1 Mine Exploder "Earthworm" – This mine exploding equipment, which was meant to be used with the boom on the M32, was essentially the T1 mine exploder with slightly different trailing discs. Developed and produced in 1943. It saw limited use in the war.[14]
- T2E1 Mine Exploder – This mine exploding equipment, which was meant to be used with the boom on the M32, was essentially the T2 mine exploder, but scaled up for use by the U.S. Marines. It was impractical, and the project was abandoned in October 1943.[14]
