Online Aviation Pics,Videos and ForumThe Leopard 2 is a German main battle tank produced by the German company Krauss-Maffei Wegmann and since the year 2003 by Spanish company Santa Bárbara Sistemas. Developed in the early 1970s and first entering service in 1979, replacing the earlier Leopard 1 as the foremost MBT in the German Army. Its different versions have served in the armed forces of Germany and ten other European countries, as well as non-European countries. More than 3,480 Leopard 2s have been manufactured.There are two main development batches of the tank, the original models up to Leopard 2A4 which have vertically faced turret armour, and the "improved" batch, namely Leopard 2A5 and newer, which have angled arrow-shaped turret add-on armour together with a number of other improvements. All models feature digital fire control systems with laser range-finders, fully stabilized main gun and coaxial machinegun and night vision equipment (first vehicles used a Low-Light Level TV system or LLLTV, thermal imaging was introduced later on). The tank has the ability to engage moving targets while moving over rough terrain. It can drive through water 4 meters deep using a snorkel or 1.2 meters without any preparation and climb vertical obstacles over 1 meter high. The tank is powered with a turbo-charged multi-fuel V12 diesel engine that produces 1,500 horsepower.Even as the Leopard was entering service in 1965, an up-gunned Leopard with the new Rheinmetall L44 120-mm gun being was considered to keep pace with the newer Soviet designs, but this was cancelled in favour of the joint MBT-70 "super-tank" project with the United States. The MBT-70 was a revolutionary design, but after large cost overruns, Germany withdrew from the project in 1969.Work on a national development was started in 1970 by Krauss-Maffei. A year later a choice was made for it to be based on the earlier Experimentalentwicklung (later named Keiler) project of the late sixties (itself derived from the vergoldeter Leopard or Gilded Leopard), instead of being a modified MBT-70 or Eber. The name of the design was determined in 1971 as "Leopard 2" with the original Leopard retroactively becoming the Leopard 1. Seventeen prototypes were ordered that year (only sixteen hulls were built). They had to have a maximum weight of fifty metric tons.Leopard 2A4 of the Polish Army.Leopard 2A4 of the Polish Army.Leopard 2A4 of the Singapore ArmyLeopard 2A4 of the Singapore ArmyOn 11 December 1974 a Memorandum of Understanding was signed with the USA for the possible joint production of a new MBT, after the Americans had bought and investigated prototype hull number seven in 1973. In view of the experiences in the Yom Kippur War a much higher level of protection was demanded than was implemented in the prototypes, that used heavily sloped spaced armour. The weight class was increased to sixty tons. Prototype turret number fourteen was changed to test a new armour configuration, and was turned into a blockier looking turret as a result of using vertical steel perforated armour; it already had been much more voluminous than the turret of a Leopard 1 because of a large internal ammunition storage locker in the rear. The Leopard 2 thus initially used perforated armour but not Chobham armour as often claimed. PT-14 used the 120 mm Rheinmetall gun (as eventually did the U.S. Abrams). After this two new prototype hulls and three turrets were ordered, one (PT-20) mounting the original L7A3105 mm gun and a Hughes fire control system, a second (PT-19) with the same fire control system but able to "swap out" the gun for the 120 mm Rheinmetall design (it was indeed so changed by the Americans), and one more (PT-21) mounting the Hughes-Krupp Atlas Elektronik EMES 13 fire control system, with the 120 mm gun.
