It was designed based upon requirements that were determined by the US Army in the late s.
It was intended to propel heavy projectiles over vast distances, with the intent of attacking strategic targets in the enemy’s rear area from the frontline. Examples of such targets include fuel dumps, train stations, airbases, and command centers.
During the formulation of the requirements that spawned the M’s development, a towed mm gun was also considered by the US Army, but the mobility offered by a self-propelled mm gun was deemed far more important for running artillery missions in Central Europe. Though in an ironic twist of fate, the Soviet Union developed and fielded equivalents to both a towed and 175km mm gun – the mm S and mm 2S7 Pionrespectively. Production of the 175mmm SPG began inand continued until175mmm a total of units built.
The M is It has a ground clearance of 0.
The dominant recognition feature of the M is its colossal mm gun, which is thin, extremely long, and has a bull barrel. The 175mmm sits atop a carriage in a slot that allows the tube to recoil rearward.
This carriage is attached to a rotating mount at rear of the chassis, while the front of the carriage is attached to a pair of tall, narrow gun carriage cheeks by a pair of long pneumatic struts. The chassis itself is largely flat and featureless, with a short and shallow frontal slope, and the driver’s hatch at the extreme front-left of the vehicle.
The M has a flat-track, with no return rollers; instead, the track rests atop the 5 very large roadwheels. The drive sprocket is forward, and there is m017 return roller. A large, hydraulically deployable spade is fitted to the rear of the M’s chassis, which may also be used as a dozer blade.
This spade is dug into the ground m17 firing the mm gun. It is highly doubtful that the M can be fired safely without deploying it. The M is operated 715mm a crew of 13 men. There is room for 5 crew members on board. The driver sits in the aforementioned position, with the two gunners sitting atop the chassis on the left and right of the weapon mount, and two loaders sitting atop the right side of the weapon mount.
The remainder of the crew rode in accompanying M tracked cargo carriers or M FAASVs, some of which carried additional ammunition and supplies. The fuel capacity is 1 liters, allowing for a km range.
The M is a rifled bore mm gun as opposed to a howitzer with a 60 caliber tube. It fires 79 kg projectiles at 1 rpm, out to a range of up to 40 km. Depending on the type and number of charges used in each shot, and the maintenance applied to the mm M gun, its tube life could span from to 1 rounds early M tubes could only withstand full charges.
Only 2 types of mm ammunition were developed for the M gun; the Due to the tremendous size and weight of the ammunition, as well as the propellant charges used to project it, only 2 rounds are carried on the M itself. In practice, additional ammunition is carried by support vehicles. While the M excels in mobility and firepower, it is greatly lacking in protection.
The only crew position with any protection or even cover from the elements is the driver’s station, whose 13 mm thick RHA steel armor only enough to protect from blasts, shell splinters, and 7.

Protection against casualties by NBC weapons requires the crew to don 175km clothing, such as the MOPP suit, but no protection is offered to any crewman against any weapons. It goes without saying, but the M’s crew is thus extremely vulnerable to counter-battery fire, snipers, strafing runs, and even the j107 of the M’s own nuclear ammunition.
Sets of Kevlar shields were issued to M batteries in order to lessen thier vulnerability, but the benefits these offered were considered by crews to be poor, in light of the difficulty of carrying, erecting, and removing them.
In practice, the Kevlar shields were usually left stowed on the sides of Ms, and were sometimes even thrown away by crews, prior to 175m, the field. Despite its vulnerability, the M had enjoyed an outstanding combat record. In Vietnam, it was the only land-based US artillery piece that outranged the infamous Soviet mm M with a range of 27 kmand the M gained fame in the Siege of Khe Sanh for this feat.
The Ms operated by Iran also saw extensive combat service, and were used throughout the Iran-Iraq War alongside mm M Koksansin the later years of the 175m.

The status of these weapons is uncertain, but they are probably still operable. M ; this is basically the same chassis, mounting a mm howitzer instead of a mm gun. Because both the M and M are fully-modular and thier weapons are easily interchangeable, Ms frequently became Ms – and vice-versa – in armies that operated both weapons.
All US-operated Ms were converted into MA2 howitzers bythough the latter has since been phased out of service as well. M armored recovery vehicle, also uses the same chassis as the M Romach – an Israeli variant of the M, apparently with no significant modifications.
