1950s on behalf of the United States. Developed by Detroit Arsenal, the
M-47 Patton Tank combined the turret from the problematic T-42 with the
hull of the M-46. They were frequently deployed by NATO to global
hotspots and even used as target practice in the 1970s once they had
outlived their usefulness on the battlefield.
The heart of an M-47 tank, the AV-1790-5B engine, now beats out 800 horsepower, a number equal to five 350 Chevys, inside Jay Leno's legendary "tank car."
