The M53 self-propelled howitzer was a self-propelled, armored artillery gun with a caliber of 155 mm, which was produced by the American company General Motors from 1952 to 1953. They were procured by many NATO member states. The howitzer was used intensively , especially during the Vietnam War . After the end of the war it was retired from the US Army.
Assemblies of the M47 battle tank were used , but the direction of travel was reversed. The turret now sat on the former bow of the hull of the main battle tank. The turret in which the driver sat was only weakly armored (against fragmentation and handgun fire). The engine and drive ring gear were now in front. To do this, the gearbox was rotated and adjusted. A hydraulically moved earth spur at the stern supported the gun when firing.
The M55 was largely identical, but had a barrel with a caliber of 203.2 mm (8 inches). 10 rounds could be carried in the turret. One bullet weighed approx. 96 kg. The photo shows an M55, some of which were also used in individual divisional artillery units of the Bundeswehr in the 1960s .
