Hoffman tank gunfire simulator

Last updated

Introduced in the early 1980's, the Hoffman tank gunfire simulator is a pyrotechnic device manufactured by Diehl Defence, used in military training alongside non-gunfire training systems such as MILES. It consists of an array of tubes (usually nine, [1] though the variant for the Leopard 2 has seventeen [2] ) resembling a multiple grenade launcher into which explosive cartridges are inserted: these generate a flash, sound and smoke plume designed to imitate the firing of a tank gun.

Description

The Hoffman simulator mounts to a bracket which is mounted somewhere near the front of a tank's turret. On the M1 Abrams it is clamped to the fume extractor,[ citation needed ] while on recent variants of the Leopard 2 it is mounted on the frontal turret armor.[ citation needed ] The system is manually loaded and fired electrically, with firing linked to the trigger of the tank's main gun.

The system is referred to as the "Simulator Tank Gunfire: Main Weapons Effect Signature" in US service, with the cartridges referred to as Simulator, Flash, Artillery M21. [3]

Safety concerns

Over the course of 20 years of service with the US Army, the Hoffman Device acquired a reputation for being prone to accidental discharges: while it is only supposed to fire when triggered electrically, there were numerous cases where static electricity or other local electrical fields resulted in uncommanded firing. A series of internal documents obtained by CBS News in 2003 included statements that "the ammunition is always unsafe" and saying many of the devices were "an accident waiting to happen." [4]

In early 2004, modifications were made to Hoffman simulators to prevent uncommanded firing, and a notification was circulated stating that any unmodified devices found in stock should be destroyed. [5]

The M1 Abrams is a third-generation American main battle tank designed by Chrysler Defense and named for General Creighton Abrams. Conceived for modern armored ground warfare and now one of the heaviest tanks in service at nearly 68 short tons, it introduced several modern technologies to US armored forces, including a multifuel turbine engine, sophisticated Chobham composite armor, a computer fire control system, separate ammunition storage in a blowout compartment, and NBC protection for crew safety. Initial models of the M1 were armed with a 105 mm M68 gun, while later variants feature a license-produced Rheinmetall 120 mm L/44 designated M256.

<span class="mw-page-title-main">Leopard 1</span> Main battle tank family of German origin

The Kampfpanzer Leopard 1 is a main battle tank designed by Porsche and manufactured by Krauss-Maffei in West Germany, first entering service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armour of limited value, the Leopard design focused on effective firepower and mobility instead of heavy protection. It featured moderate armour, only effective against low caliber autocannons and heavy machine guns, giving it a high power-to-weight ratio. This, coupled with a modern suspension and drivetrain, gave the Leopard superior mobility and cross-country performance compared to most other main battle tanks of the era, only being rivaled by the French AMX-30 and Swedish Strv 103. The main armament of the Leopard consisted of a German license-built version of the British Royal Ordnance L7 105 mm rifled gun, one of the most effective and widespread tank guns of the era.

The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft.

The M48 Patton is an American first-generation main battle tank (MBT) introduced in February 1952, being designated as the 90mm Gun Tank: M48. It was designed as a replacement for the M26 Pershing, M4 Sherman, M46 and M47 Patton tanks, and was the main battle tank of the U.S. Army and U.S. Marine Corps in the Vietnam War. Nearly 12,000 M48s were built, mainly by Chrysler and American Locomotive Company, from 1952 to 1961. The M48 Patton was the first U.S. medium gun tank with a four-man crew, featuring a centerline driver's compartment and no bow machine gunner. As with nearly all new armored vehicles it had a wide variety of suspension systems, cupola styles, power packs, fenders and other details among individual tanks.

<span class="mw-page-title-main">M60 tank</span> American second generation main battle tank

The M60 is an American second-generation main battle tank (MBT). It was officially standardized as the Tank, Combat, Full Tracked: 105-mm Gun, M60 in March 1959. Although developed from the M48 Patton, the M60 tank series was never officially christened as a Patton tank. The US Army considered it a "product-improved descendant" of the Patton tank's design. The design similarities are evident comparing the original version of the M60 and the M48A2. It has been sometimes informally grouped as a member of the Patton tank family. The United States fully committed to the MBT doctrine in 1963, when the Marine Corps retired the last (M103) heavy tank battalion. The M60 tank series became America's primary main battle tank during the Cold War, reaching a production total of 15,000 M60s. Hull production ended in 1983, but 5,400 older models were converted to the M60A3 variant ending in 1990.

Various iterations of the Leopard 2 continue to be operated by the armed forces of Germany, as well as 13 other European countries, and several non-European countries, including Canada, Chile, Indonesia, and Singapore. Some operating countries have licensed the Leopard 2 design for local production and domestic development.
