Armament 120 mm TDA rifled mortar MO-120-RT, Mortar 2R2M. Development By TDA . Description The body of the PR14 bomb resembles an artillery shell. It has a tapering ogive, parallel-walled section, a pre-engraved driving band and a boat tailed section at the rear. There is a pre-engraved driving band and a plastic obturating ring at the boat tail. A tubular tailboom is attached to the base of the projectile. This carries a primary cartridge in its base and has 11 horseshoe shaped secondary propellant increments
clipped around it. The increments are colour-coded; four red, five white and two blue. The bomb is drop loaded by engaging the pre-engraved driving band with the rifling at the muzzle. Upon the explosion of the propelling charge, the obturating ring is driven up the boat tail and lodges behind the driving band to act as a seal. A delay element in the forward end of the tailboom is ignited. Shortly after the bomb has left the muzzle the delay burns through and ignites a small charge which blows off the tailboom, so that it lands about 100 m from the mortar. With an angle of fall of 69º, the lethal area for a ground burst is approximately 1,290 m ² and for an airburst at 3 m height 1,530m ² . There area three versions in addition to the HE bomb, all of which have identical ballistics. These are White Phosphorous (WP) smoke, practice and inert. Manufacturer TDA .
