The M43 Howitzer Motor Carriage 203mm (8inches) was an American self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and HVSS that was introduced at the end of the Second World War.

The M43 shared the same chassis as the more widely produced M40 Gun Motor Carriage, which instead mounted a 155mm gun, and were designed by the Pressed Steel Car Company.

A production run of 576 was planned originally, but in the end only 24 were produced and another 24 were converted from M40 hulls. The M43 went on to serve in the Korean War, and was retired after its conclusion.

Equipped with a M115 203 mm (8") Howitzer, it was designed to replace the earlier M12 Gun Motor Carriage 155mm. Its prototype designation was the T89, but this was changed to the M43 in March 1945. The 41.5 ton vehicles struggled to keep up with mechanized formations, but were successful when employed in more stationary roles.

The M43s were used in action in the Korean War, where they were well suited to the static fighting there, their high angle of fire permitting them to hit the rear slopes of hills.

To start this project, I used the excellent AFV Club kit (#35031) of M40 switching the 155mm metal gun barrel by the AFV Club kit (#35S-06) M115 8 inches howitzer aluminum gun barrel.

Notice the Kojak inspecting the project!!
|Booklets: Notice the drawings...|
Same parts except the barrel.

The kit (#35S-06) M115 8 inches howitzer was not "crippled" since I used the 155mm barrel left over from the M40 AFV Club kit (#35031) to turn the 8 inch howitzer into Long Tom 155mm gun. "In modeling, nothing is lost, everything is transformed" (First Law of Conservation of Model Stuff).
