Comparing: T71 vs. Aufklärungspanzer Panther vs. AMX 13 90

Experimental airborne light tank with an oscillating turret and automatic loading. Developed by Detroit Arsenal from 1952 through 1953 as a replacement for M41. The armament was deemed ineffective, and the development was stopped after one wooden prototype had been built.

Planned heavy reconnaissance vehicle. The plans called for using the Panther hull in order to facilitate rapid mass production. The vehicle was to feature the Leopard turret with a gun not longer than the tank's hull, which was to ensure maneuverability in forested terrain. No prototypes were built.

In the early 1960s, the 75-mm gun with a muzzle velocity of 1,000 m/s was deemed outdated. The vehicle received the new 90-mm F3 gun that used more powerful HEAT shells. This modernization did not require any significant changes to the turret or vehicle design. The first vehicles were manufactured in February, 1967. The existing vehicles underwent the gun modernization as well.
