Armament TDA 120 mm rifled mortar MO-120-RT, Mortar 2R2M. Development By TDA to provide an illuminating projectile for the rifled mortar. Description The PRECLAIR resembles the PR14 HE bomb, with a similar body shape, prerifled driving band, obturating ring and tailboom that detaches in flight. However, the boat tail is slightly different in contour and the latter part of it is a separate component pinned to the main body. The interior contains a parachute and flare container. A time fuze ignites an expelling
charge which blows off the rear of the boat tail, allowing the contents of the body to be ejected. At 420 m height of burst, the PRECLAIR's initial illumination covers an area of 1,500 m diameter with 5 lux over a 700 m diameter area, tapering to 2 lux at the outer edges. In the final stage of descent, the illuminated area expands to a diameter of 1,700 m, with 5 lux over an 1,080 m area, tapering to 2 lux at the outer edges. Manufacturer TDA .
