Inert Cold War Polish MN-121 Air Drop Anti Tank Mine. This mine is in new old stock condition. First set of photos is the mine fully deployed with the parachute and legs extended. The mine uses a magnetic influence fuse, which triggers the mine when a vehicle passes over it. The mine also has an anti-handling device which triggers the mine if it is moved. The mine's warhead is a shaped charge design containing approximately 700 grams of RDX. The manufacturer claims that it is capable of penetrating 60 millimeters of armor at an offset of half a meter. The mine can be deployed either from aircraft, a specialized mine laying system or 122 mm artillery rockets. When required the mine is ejected from a storage canister, and shortly afterwards a small parachute is opened, which both retards the descent and keeps the mine correctly oriented as it descends. Once the mine lands on the ground the top of the mine is ejected, along with the parachute and the spring-loaded legs bring the mine upright. The mine can be manually programmed to self-destruct after a period of 3, 6, 12, 24 or 96 hours. A very cool and uncommon mine for your ordnance collection.
