M-110 8in Self-propelled Howitzer
The M110 is a heavy but highly mobile and maneuverable self-propelled artillery piece designed to provide general artillery support to infantry or armor over a wide range of terrain conditions. It can be airlifted in large cargo aircraft.
The M-110 entered service with the U.S. Army in 1963, gradually replacing the M-55 8-inch Self-Propelled Howitzer. The gun is an 8-inch Howitzer traversing in it's mount at the rear of the vehicle. The large spade at the rear is hydraulically operated. When lowered it keeps the vehicle in place as the gun is fired, opposing the massive recoil. The 8-inch howitzer fired a 200-pound projectile as much as 25 miles, while being the most accurate weapon in the field artillery of its time.
M-110 8 inch (203mm) Self-propelled Howitzer
The M-110 entered service with the U.S. Army in the early 1960s. It was developed as the T236 prototype by Pacific Car and Foundry Company (PACCAR, Inc.), standardized as the M110 in 1963. The M-110 8 inch (203mm) Self-propelled Howitzer has a crew of five, weighs 62,500 lbs, and has a top road speed of 34 mph with a range of 325 miles.
The same diesel powered chassis is used for the M107 self-propelled 175mm gun and the M110. In Vietnam, the M110 8 inch howitzer was found with most division artilleries, and both the 8-inch howitzer and M107 175mm gun were with field force artillery. At field force the proportion of 8-inch and 175-mm. weapons varied. Since the weapons had identical carriages, the common practice was to install those tubes that best met the current tactical needs. One day a battery might be 175mm while a few days later it might be half 175mm and half 8-inch.
The M107 self-propelled 175mm gun and the M110 self-propelled 8in (203mm) howitzer were both characterized by rapid barrel wear and the need to be able to change the barrels frequently and simply. The M578 Light Armored Recovery Vehicle (VTR) was developed to service these requirements using the identical diesel powered chassis.
