MBT-70

[Sewter]

My friend, I did not mean to offend. Though the weapon was a longer barrel 152mm prototype, the fact that it was to incorporate the Shillelagh missile is still an amazing idea.

"The US prototype was equipped with a 152mm gun launcher with an auto loader. It was capable of firing AP/HE/WP rounds and the Shillelagh Missile. The main armament was to be a long-barrelled improved XM-150 variant of the XM-81 gun/launcher mounted on the M551 Sheridan and the M60a2 Patton. This was a much more reliable weapon than the earlier variant, firing Sabot, HE, and Cannister rounds in addition to the Shilelagh A/T Missile, but the earlier weapon's reputation was such that it was a lost cause from the start. It had a coax 7.62 machinegun and a 20mm AA remote control gun in a separate part of the turret. It would pop up out of twin hatches and fire at the target. The German version had a 120mm autocannon, instead of the 152mm gun launcher."
