MBT-70
main battle tank

The MBT-70 (German: KPz 70 or KpfPz 70) was an American–West German cancelled joint project to develop a new main battle tank during the 1960s.
The MBT-70 was developed by the United States and West Germany in the context of the Cold War, intended to counter the new generation of tanks developed by the Soviet Union for the Warsaw Pact. The new tank was to be equipped with a number of advanced features such as newly developed "kneeling" hydropneumatic suspension and housing the entire crew in the large turret, and was armed with a 152mm XM150 gun/launcher, which could use both conventional ammunition and the MGM-51 Shillelagh missile for long range combat.
The program faced significant challenges from the start, including poor communication and coordination between the American and West German teams working on the project. The U.S. Army and the German Bundeswehr had different requirements which were not aligned and were not resolved before the project was too far advanced to be changed.
By the late 1960s, the development of the MBT-70 was well over budget, leading West Germany to withdraw from the project in 1969. The United States continued development of the MBT-70 (spun off as the XM803) until 1971 when the program was finally cancelled, with funds and technology from the MBT-70 project redirected to the development of the M1 Abrams. West Germany independently developed the Leopard 2 as its new main battle tank.
History
Background
The joint German–US main battle tank program was the brainchild of US Secretary of Defense Robert McNamara. After serving in the US Army Air Forces during World War II, McNamara became a "Whiz Kid" at Ford Motor Company, where he later rose to become president.

Why this record matters
The phrase “main battle tank” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated May 30, 2026. The linked authority identifier is Q707466. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1969 and 1971.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
