M88 recovery vehicle

(Redirected from M88A2 HERCULES)

The M88 recovery vehicle is one of the largest armored recovery vehicles (ARV) in use by United States Armed Forces. There are three variants, the M88, the M88A1, and the M88A2 HERCULES (Heavy Equipment Recovery Combat Utility Lifting Extraction System). The M88 series has seen action in the Vietnam War, the Persian Gulf War, the Iraq War, and the War in Afghanistan, and to a lesser extent during the Kosovo War, where they were deployed to help recover heavy armored vehicles of the Allied ground units. As of 2000, the M88A2 replacement cost was around US$2,050,000.[1]

History

edit

Design

edit

In response to the information about the T-54A tank the US had to develop new M60 tank (production started in 1959) heavier than 46 metric tons, which M74 armored recovery vehicle was unable to retrieve.

The design of a new ARV vehicle was based on the chassis and parts of the automotive component of the M48 Patton and M60 tanks. The original M88 was introduced in 1961, M88A1 in 1977, and the current M88A2 introduced in 1997.[1]

Development

edit

It was originally manufactured by Bowen McLaughlin York, later the BMY division of Harsco Corporation, in 1961. The company later merged with FMC Corp. to form the United Defense Industries in 1994. United was acquired by BAE Systems in 2005 to become BAE Systems Land and Armaments. In February 2008 BAE was awarded a $185 million contract modification from the U.S. Army to manufacture 90 Army-configured M88A2s, four United States Marine Corps-configured M88A2s and authorized spares list parts.[2]

Role

edit

The M88's primary role is to repair or replace damaged parts in fighting vehicles while under fire, as well as extricate vehicles that have become bogged down or entangled. The main winch on the M88A2 is capable of a 70-ton, single line recovery, and a 140-ton 2:1 recovery when used with the 140 ton pulley. The A-frame boom of the A2 can lift 35 tons when used in conjunction with the spade down. The spade can be used for light earth moving, and can be used to anchor the vehicle when using the main winch.[1]

The M88 employs an Auxiliary power unit (APU) to provide auxiliary electrical and hydraulic power when the main engine is not in operation. It can be used to slave-start other vehicles, provide power for the hydraulic impact wrench, as well as a means to refuel or de-fuel vehicles as required. The M88 series of vehicles can refuel M1 tanks from its own fuel tanks, but this is a last resort due to the possibility of clogging the AGT-1500's fuel filters. The fuel pump draws fuel from the bottom of the fuel cell, and with it, all of the sediment that has accumulated with time.[1]

Variants

edit
  • M88 – 1961
  • M88A1 – 1977
  • M88A2 Hercules – 1991
  • M88A3 Hercules – future

All variants have a 12.7 mm M2 Browning .50 caliber machine gun, 432 mm ground clearance, 2.6 m fording depth, 1.1 m wall climb and 2.6 m trench crossing capabilities. There has been no major deviation in battlefield role through the M88 series. The later models are merely able to lift heavier loads. The M88A1 was designed around the now obsolete M60 Patton tanks, so it was in light of the fact that two M88A1s were required to tow the new M1 Abrams tank that the decision was made to upgrade to the M88A2 in 1991.[1]

The original M88 produced from 1960 to 1964 used the Continental AVSI-1790-6A gasoline engine. It had 980 HP at 2800 rpm, as well as a 10 HP gasoline auxiliary power unit.[3] The M88A1 was powered by the Continental AVDS-1790-2DR Diesel engine and had a 10 HP Diesel auxiliary power unit.[1]

While the original M88 and M88A1 are designated as a "medium recovery vehicle", the M88A2, original designation being M88A1E1, is designated as "heavy recovery vehicle". They are all similar in many fundamental ways. The later version is distinctly heavier at 70 tons, compared to the original 56 tons, and uses a different engine, an AVDS 1790-8CR with 1050 hp, compared to a Continental AVDS-1790-2DR, with 750 hp.[1]

The M88A2 is slightly larger than its predecessors, at 8.6 × 3.7 × 3.2 m compared to 8.3 × 3.4 × 3.2 m. It has a lower top speed (40 km/h) and a significantly lower road range at 322 km, compared to 450 km. There have been improvements in braking and steering. The M88A2 has upgraded armor protection including armored track skirts and applique armor panels, which both previous models lack. The later M88A1 and M88A2 models are equipped with nuclear, biological, chemical (NBC) defenses and a smoke screen generator. The crew number decreased from 5, to 3–4, to 3 through the series.[1]

In February 2017, the Army awarded BAE Systems Land and Armaments a $28 million contract modification for the procurement of 11 M88A2 recovery vehicles.[4]

The upgrades include a modernized powertrain that boosts horsepower and torque, a seventh road wheel for enhanced stability, and hydro-pneumatic suspension units that improve cross-country mobility and recovery operations. By increasing the towing capacity from 70 short tons (64 t) to 80 short tons (73 t), it eliminates the need for two vehicles for raising and moving the newer, heavier M1 Abrams tanks, effectively bridging the single-vehicle recovery gap.[5]

Criticism

edit
 
A M88 mired as it attempted to crest a hill in heavy rain during night training in Fort Hunter Liggett, California.

One of the main issues afflicting the M88A2 is a high rate of winch failures. The leading cause of these failures is operation of the winch without tension on the cable. This leads to "birdnesting" loose wrapping and bunching up of the cable.[1]

There is also concern with loss of tractive force when an M88A2 tows a heavy M1 Abrams on a slope in wet, muddy conditions. The M88A2 was extensively tested at the Aberdeen Proving Ground, Maryland, and in August 1998, was officially approved for the towing of 70-ton combat vehicles such as the M1 Abrams.[1]

Combat history

edit

About 8 M88s were sent to Ukraine during Russo-Ukrainian War as a part of a US aid package. They were used extensively in the 2023 Ukrainian counteroffensive.[6] According to Oryx, at least 2 M88A1s were destroyed by Russian troops, while another one was captured.[7]
