If the gun was facing hostile artillery the gun would fire and relocate where these crewmen would reload the M107 at the new location to avoid counter-battery fire. Since the weapons had identical carriages, the common practice was to install those tubes that best met the current tactical needs. The M107's combat history in U.S. service was limited to the Vietnam War and also saw extensive combat use in Israeli service. the projectile normally weighs 66.78 kg, but a hydraulic device assembled to the back of the frame facilitates its loading: it raises it ground, positions it and pushes it in the cylinder head. The fatigue life of this replacement design was increased at least ten-fold from the original design, and in service failure was eliminated. 7 sold. The M107 was able to launch a 147 lb (67 kg) projectile out to 21 miles (34 km), at 0 deflection and 800 mil (45°) elevation. $30.00. This led the U.S. Army to issue a requirement for a new series of self-propelled artillery: lighter to be transportable by air, while continuing the practice of deriving several vehicles from the same chassis which simplified maintenance and training. Because no special end seals, high pressure pumps and lines, or expensive external restraining fixtures are required, the swage autofrettage process has been greatly simplified, as well as made the process safer for the machinist. According to GlobalSecurity.org, the M107 fired only one type of conventional round, the M347 high-explosive round. The M107 was fast for an armored vehicle, with a top speed of 50 miles per hour, and could go almost 450 miles on a single tank of fuel. Buy It Now. It shared many components with, and in many cases was replaced by later versions of, the M110. var setNptTechAdblockerCookie = function(adblocker) { One drawback of the M107 in combat was that laying the gun involves skilled minute movements of the entire vehicle. 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. and half 8-inch. Although this system is no longer in service with the U.S. military, it continues to provide safe and effective fire power to NATO allies. Free shipping. The M107 175 mm self-propelled gun was used by the U.S. Army from the early 1960s through to the late 1970s. document.getElementsByTagName("head")[0].appendChild(script); Itis the FUZE that costs money. $189.99. During the 1950s the standard of US Army motorized 203mm artillery was the M55, based on the chassis and the turret of the M53 155mm Self-Propelled Gun, which used some components from the M48 tank. #ga-ad {display: none;} 07-09-2013 19:24:56 ZULU. SGT Max Cones (gunner) fires a M107, 175mm self-propelled gun, Btry C, 1st Bn, 83rd Arty, 54th Arty Group, Vietnam, 1968. The 175-mm. This was used to good effect in Vietnam, where the barrels could be swapped as needed at firebases. Long thin barrel without a fume extractor or muzzle brake. Given the amount of firing on-going, this was a potential crisis for field units, and the impact was heard at the Secretary of Defense level. Some of the most notable are the French 75 of World War I, or the Napoleons used during the Civil War, or the German 88. The French 75 – the First Modern Artillery Piece The French 75mm Field Gun was a quick-firing field artillery piece adopted by … Vietnam War is a FANDOM Lifestyle Community. @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { The hydraulic pump was sometimes improperly used to dig in the rear spade, resulting in damage to the hydraulic spade cylinders after the first round was fired. Certain country replaces it by trucks 6 X 6, whose possibilities any ground are however quite lower than that of the gun itself. The M107 was exported in Germany, in South Korea, in Spain, in Greece, in Holland, in Iran, in Israel, in Italy, with United Kingdom and in Turkey. When retubing was done at the battalion level the M578 Light Recovery Vehicle was used. The only projectile used by the American army is HE M437A1 or M437A2 whose range is approximately 32.7 KM. Gun tubes with fracture related mechanical properties in the same range as those of the failed tube were removed from service. the Artillery Memorial Bridge gun, D Battery, 134th Field Artillery and the Field Artillery in general. This retubing was usually accomplished by the supporting ordnance company or a fixed depot as it requires an overhead electric rail winch and chassis modifications for the E2 barrel. The gun was assigned to corps artillery units and a number of M107/M110 composite units were formed allowing the option of responding with the longer range M107 or the more accurate M110. }, Page last modified: Pacific Car and Foundry company developed a number of prototypes.

The M-110 was a “Howitzer” (low velocity, high trajectory, short range). The M107 self-propelled 175-mm. Inclusions tended to contribute to the faster crack growth - and brittle failure mode. It could fire shells as far as 25 miles away – and this long range proved very handy during the Vietnam War. Free shipping. But some are less well-known, but packed a big punch – or long range – of their own. This allows for faster reload times and its high maneuvering speed and fast reload time allows the M107 to practice shoot-and-scoot, redeploying before the firing position can be zeroed in on. From Latvia. Temper embrittlement also contributed to brittle failure mode. The barrels could not be replaced using a single M578 due to weight and the need for precise placement of the barrel into the cradle to prevent damaging the barrel brass runners. Temper embrittlement was specifically noted as a concern.
