US Army engineers have developed a new muzzle brake design for the M119 towed howitzer system in a bid to reduce the weapon's recoil.

A team of engineers at Watervliet Arsenal designed a 105mm low blast overpressure (LBOP) muzzle brake, which redirects propellant gases towards the gun's rear section.

The more efficiently a muzzle break redirects gases to the rear of the gun, the greater the recoil reduction, according to LBOP design engineer Robert Carson.

LBOP programme lead Alan Ng said: "It is important to the warfighter because it allows them to be more lethal by sustaining [a] higher number of rounds fired per day.

"The blast overpressure from this new muzzle brake that is experienced by the artilleryman is significantly lower."

"The reduction in impulse noise [blast overpressure] varies between 13% and 48% at various quadrant elevations and crew locations."

The new LBOP muzzle brake is said to be the first high-calibre muzzle brake designed specifically for an existing gun system, and increases safety compared to the current brake.

Ng said: "The reduction in impulse noise [blast overpressure] varies between 13% and 48% at various quadrant elevations and crew locations.”

The 105mm LBOP muzzle brake will be used with the M119 towed howitzer during short-range howitzer missions and training, the US Army stated.
