PLAMEN AIRCRAFT GUN POD PL-20
The PL-20 package represents a set of products comprising an aircraft weapons system and its ground accessories. The 20 x 102 mm weapons system consists of the ZPL-20 aircraft gun, the KPL-20 gun pod, the MPL-20 aircraft ammunition (TP, TP-T, API-T or HEI cartridges), PYR-20 cartridges and elements of the P-20 ammunition feed belt. The ground accessories consist of the feed belt charger PLN-20, the ground control device LUN 2469, the adjustment telescope RD 20-460, the gun assembly stand, the gun pod assembly, the set of spare parts 1:1 and 1:3 and the tool set.
The ZPL-20 is a high rate-of-fire, two-barrels electrically controlled automatic gun for aerial usage resting together with the ammunition box and the electronic control block in the KPL-20 gun pod. The pod may be suspended under a standard NATO pylon and is standardly linked to the board control computer of the aircraft.
During all allowed flight modes the PL-20 package enables aerial fire at air targets (in aerial combat and for aircraft self-defense) and at ground targets, to provide combat support for or defense of ground forces.
The ground accessories of the PL-20 are designated, in particular, for the pre-flight procedures and post-flight checks of the PL-20, as well as for its maintenance, transport and storage.
The ZPL-20 gun and MPL-20 ammunition are also utilizable for ground applications. In such cases the gun may be mounted on fixed and/or mobile platforms.
In 2004, all parts of the PL-20 have been certified for use in military aviation in compliance with the STANAG and MIL international standards. The ammunition is compatible with the M39 / M56 / M61A ammunition series.
Based on successful finalization of control and end-user tests, the PL-20 has been integrated into the armaments of L-159 aircraft and, subsequently, employed by the Armed Forces of the Czech Republic.
