HPD series of mines
From Wikipedia, the free encyclopedia
The HPD-1, HPD-2 and HPD-3 are a series of French electrically fuzed anti-tank landmines that use Misznay Schardin effect warheads. The entire series of mines conform to the United States MIL-STD-331.

[edit] HPD-1
The HPD-1 consists of a large case with a prominent circular section at one end that contains the clearing charge and Misznay Schardin effect warhead, and a rectangular section that contains the batteries and seismic and magnetic sensors that the electronic fuze uses. It was developed to be laid automatically from the Matenin minelayer or by hand.
When the seismic sensor detects a suitable target the magnetic sensor is then monitored, when a vehicle with a mass of more than eight tons passes over the mine, triggering the magnetic sensor the mines warhead is triggered. First the mine detonates a clearing charge, which removes any earth that may have been laid over the mine, then it triggers the Misznay Schardin effect charge, which projects a slug of metal upwards. In testing the mine penetrated up to 100 millimeters of armour, although it can official penetrate only 70 millimeters.
[edit] HPD-2
The HPD-2 is a development of the HPD-1 mine. It incorperates a series of enhancements to both the warhead and fuzing mechanism. The mine's warhead is said to be a "second generation" Misznay Schardin effect design capable of penetrating up to 150 millimeters of armour. In addition it can be laid in water up to one and half meters of water.
The mine arms itself after an initial delay of ten minutes and self-neutralizes after 30 days. It also incorperates an anti-handling device, which is sensitive to motion and the signals produced by mine detectors.
As of 2006, approximately 400,000 HPD-2 series mines have been ordered. The mine is in service with the French Army, and is sold to the Belgian, Norwegian and Swiss armed forces.
[edit] HPD-3
The HPD-3 is a further development of the HPD-2 featuring a programmable fuze. It has a three pin interface for a programming device. It can be set for an active period of either 30 days after which it self-neutralizes or for a shorter active period of between four and ninety six hours after which it self-destructs.
