Self-propelled artillery mount M43 8-inch self-propelled howitzer M43 (8 inch Howitzer Motor Carriage M43). Just like the M40 SPG, this unit is designed on the chassis of the M4A3E8 medium tank. The layout of the tank has been changed: in the front of the hull there is a control compartment, behind it is a power compartment, and an armored conning tower with a 203,2 mm M1 or M2 howitzer installed in it is mounted in the rear. The horizontal aiming angle of the gun is 36 degrees, the elevation angle is +55 degrees, and the descent angle is -5 degrees. Shooting is carried out with shells weighing 90,7 kg at a distance of 16900 m. The practical rate of fire is one shot per minute. At the rear of the body, a folding opener is mounted, designed to increase stability when firing. The lifting and lowering of the opener is carried out using a manual winch. To protect against air attacks, the units were armed with a 12,7-mm anti-aircraft machine gun. Just like the M40, the M43 was used in the artillery units of the High Command Reserve.
