Product Information

The M1 Garand was designed for simple assembly and disassembly to facilitate field maintenance. It can be field stripped (broken down) without tools in just a few seconds. [42] M1 Garand variant; rechambered for 7.62×51mm NATO; While the majority used the standard en bloc clip, a small number were experimentally fitted with a 10-round internal magazine loaded by 5-round stripper clips.

Retrieved November 15, 2005.The Marine Corps pursued a force restructuring plan named Force Design 2030. Under this program, all US Marine tank battalions were deactivated and its M1A1 tanks transferred to the Army by the end of 2021. [93] [94] Engineering Change Proposal 1 is a two-part upgrade process. ECP1A adds space, weight, and power improvements and active protection against improvised explosive devices. Nine ECP1A prototypes have been produced as of October 2014. ECP1B, which would begin development in 2015, may include sensor upgrades and the convergence of several tank round capabilities into a multi-purpose round. [91] From 1991 to 1994, the Army fitted 1,500 Abrams turrets with external Auxiliary Power Units (APU). APUs allow some the Abrams to run some functions without running on the engine. Some Abrams tanks that saw service during the Gulf War were fitted with such a device. [141] Although the Army favored an under-armor APU, Congress instead funded a short-term modification to 336 M1A2 Abrams. These were installed in 1997. [142] An under-armor APU located in the hull was chosen for the M1A2 SEP variant. When this proved unreliable, it was replaced with a battery-based Alternate APU starting in 2005.

ISBN 978-0-85045-451-2.M1A1HC (Heavy Common): Added new second generation depleted uranium armor components, digital engine control and other small upgrades common between Army and Marine Corps tanks. In 1990, Project On Government Oversight in a report criticized the M1's high costs and low fuel efficiency in comparison with other tanks of similar power and effectiveness such as the Leopard 2. [38] Many M1s were repaired or rebuilt after World War II. While U.S. forces were still engaged in the Korean War, the Department of Defense decided more were needed. Springfield Armory ramped up production, but two new contracts were awarded. During 1953–56, M1s were produced by International Harvester and Harrington & Richardson in which International Harvester alone produced a total of 337,623 M1 Garands. [33] [34] A final, very small lot of M1s was produced by Springfield Armory in early 1957, using finished components already on hand. Beretta also produced Garands using Winchester tooling.

The TUSK system is a field-installable kit that allows tanks to be upgraded without needing to be recalled to a maintenance depot. While the reactive armor may not be needed in most situations, like those present in maneuver warfare, items like the rear slat armor, loader's gun shield, infantry phone (which saw use on Marine Corps M1A1s as early as 2003), and Kongsberg Remote Weapons Station for the 12.7mm (.50in) caliber machine gun will eventually be added to the entire M1A2 fleet. Air Ground Defense System ( AGDS): Proposed air defense variant of the Abrams equipped with dual 35mm Bushmaster III autocannons, 12 ADATS missiles and advanced electro-optical and radar targeting systems derived from the ADATS. It was supposed to be capable of both air defense and anti-tank purposes with the ADATS MIM-146 missiles which was a dual purpose ATGM/SAM. The proposal never saw consideration and was never developed further. [191] During the 1950s, Beretta produced Garands in Italy at the behest of NATO, by having the tooling used by Winchester during World War II shipped to them by the U.S. government. These rifles were designated "Model 1952" in Italy. Using this tooling, Beretta developed the BM59 series of rifles. The BM59 was essentially a rechambered 7.62×51mm NATO caliber M1 fitted with a removable 20-round magazine, folding bipod and a combined flash suppressor-rifle grenade launcher. The BM59 is capable of selective fire. These rifles were produced under license in Indonesia as the " SP-1" series. Later, the M829A3 round was introduced to improve its effectiveness against next generation ERA equipped tanks, through usage of a multi-material penetrator and increased penetrator diameter that can resist the shear effect of K-5 type ERA. [ citation needed] Development of the M829 series is continuing with the M829A4 currently entering production, featuring advanced technology such as data-link capability. [120]

The Abrams was to be replaced in U.S. Army service by the XM1202 Mounted Combat System, but since that project was canceled, the Army has opted to continue maintaining and operating the M1 series for the foreseeable future by upgrading with improved optics, armor, and firepower.

M1 Thumper (also known as ATAC Demonstration System) was a single M1A1 [180] fitted with a heavily modified turret to trial the experimental XM291 ATAC (sometimes referred to as LW120) smoothbore gun, a more powerful replacement for the M256 capable of firing either single-piece 120mm or two-piece 140mm ammunition with only a barrel change. The 140mm rounds were too large (boasting twice the chamber volume of a M829 APFSDS and twice the muzzle energy) and heavy to be moved around by a human loader, mandating the installation of a XM91 mechanical cassette autoloader. The Thumper underwent testing in 1988 and in the 1990s at Aberdeen Proving Ground, [181] [182] where it demonstrated accuracy equal to a M1A1's but with significantly higher armor penetration capability.a b c d Rayle, Roy E.
