![]() ![]() The US Army therefore proceeded with the evaluation of the XM1 prototypes built by Chrysler and General Motors, and ultimately decided to launch full-scale development of the Chrysler design. The Leopard 2 AV was originally intended to be tested while the XM1, but the German modification program took longer than expected. Modifications included several new armor layers (like armor developed by British "Chobham" which consisted of layers of steel and ceramic armor) in the hull and a new turret with a less sophisticated system of aim. According to the military requirements of the US and Germany subject to these modifications, Porsche, Krauss-Maffei, and Wegmann designed and built the Leopard 2 AV. As a result, by 1976 the study of how Leopard 2 could be modified to resolve performance problems and emergencies and adapt to the needs of the US agreed. ![]() During 1973, negotiations began between the United States and Germany to standardize certain components between the main battle tank of these nations to the 1980. This resulted in a breakthrough in the Leopard 2 program and the first step towards the Leopard 2 AV (Austere Version). The result was a decision to improve the Leopard 2 to MLC 60 (Military Class loading 60 tons), which would allow increased armor and to modify one of the turrets with a new type of multiple layers of armor.

It permits effective use of a new APFSDS-T round, DM53 (LKE II), with a longer rod penetrator, and which is under development. A new smoothbore gun, the 120 millimetre L55 Gun, has been developed by Rheinmetall GmbH of Ratingen, Germany to replace the shorter 120 millimetre L44 smoothbore tankgun on the Leopard 2. The Leopard 2 has had technical improvements under Upgrading Level I and Level II programs. These include the Atlas Elektronik Vehicle Integrated Command and Information System (IFIS), a digital command and information system. Combat support variants include an armoredĪ variety of upgrade programs and options are available for the Leopard 2. A variety of MBT variants from 2A1 to 2A7 denote minor changes, as well as FCS upgrades. ![]()
