The M mm self-propelled Gun was largely deployed in NATO areas and its ammunition was commonly used throughout NATO forces. One such artillery piece is the M self-propelled howitzer. This mm artillery piece entered service in , alongside the M

The others follow normally on board tracked M which contains the remainder of the ammunition. The M has an extremely-low fire rate, a maximum of 2 shots per minute.

During the s the standard of US Army motorized howitzer of mm was the M55, based on the chasis and the turret of the M53 self-propelled howitzer of mm gun.

The dominant recognition feature of the M is its colossal mm gun, which is thin, extremely long, and has a bull barrel. The driver m10 the positions spade and the barrel travel lock. Leave a Reply Cancel reply Your email address will not be published. The M is a rifled bore mm m17 as opposed to a howitzer 175m, a 60 caliber tube. The gunner controls deflection the horizontal direction in which the gun is pointing.
He was also in charge of the positions spade and barrel travel lock. A certain number of 1775mm recovery vehicles were developed on the frame of M, but only the light vehicle M is used at the present time.

The gun sits atop a carriage in a slot that allows the tube to recoil rearward. The hydraulic autofrettage procedure used in the early s was an expensive, difficult, slow, and sometimes dangerous procedure where pressurized hydraulic fluid, on the order ofpsi or greater, was pumped into the bore of the tube to apply compressive residual stress at the bore.
This brought the Army to build a new series of self-propelled guns, lighter and transportable by air, derive from the same frame and some same mounting. Big gun, big 1775mm.
M mm in Vietnam. These guns fired an HE shell weighing Romach – an Israeli variant of the M, apparently with 17mm significant modifications. Put another way, as strength, pressure, and performance increase, cannon life decreases, sometimes dramatically.
The artillery piece and servants were well protected by a turret-like superstructure but it was quite heavy, at 44 tons, but had a gasoline engine which gave reduced range and could cause possible explosion hazards. M armored recovery 1775mm, also uses the same chassis as the M It was further noted that the lower life tubes were linked to longer timed – lower temperature tempering processes.
M is equipped with infra-red equipment for the night vision. Some of the “newer” cannon designs in this era, such as the original mm M Gun on the M Self-Propelled System, experimented with what were considered very high strength steels for the time with gun steel strength levels aboutpsi yield strength.
This long-range advantage, along with its ability to rapidly k107 from its previous position, made it an effective weapon for destroying North Vietnamese Army and Viet Cong command-and-control sites, communications facilities and supply-trains, while evading counter-battery fire from its longest-range Soviet counterparts in service with North Vietnam.

The M was essentially similar to the M see later only differing by its main armament which traded ammo weight and caliber for 175km. Temper embrittlement was specifically noted as a concern.

Longer tempering times allowed impurities to migrate to grain boundaries. 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.
If the gun was facing hostile artillery, the gun would fire and relocate where these crewmen would reload the M at the new location to avoid enemy counter-battery fire.
