The Oerlikon/Martin Marietta Air Defense Anti Tank System (US designation MIM-146 ADATS) is a dual-purpose short range surface-to-air and anti-tank missile system based on the M113A2 vehicle. The ADATS missile is a laser-guided supersonic missile with a range of 10 kilometers (6.2 miles), with an electro-optical sensor with TV and Forward Looking Infrared (FLIR). The carrying vehicle also has a search radar with an effective range of over 25 kilometers (16 miles).

The first firing of an ADATS missile occurred in June 1981. Canada was the launch customer for the system with 36 Units on the M113 chassis ordered for the Canadian Army in 1986. The system was further developed and produced at a new facility in Québec. The US Army also selected ADATS installed on the M2 Bradley chassis but by the time it was ready for service the ending of the Cold War led the US Army to cancel its orders, after Oerlikon invested over CHF 1 billion in the project. A small number of vehicles, many of them the developmental prototypes, entered service with the Canadian Army.

History

ADATS was trialed or proposed on a variety of different platforms to suit the needs of the user for the defense of mobile field formations or fixed sites such as airfields. Besides the M113A2 tracked vehicle chosen by Canada, ADATS was also installed on the M2 Bradley chassis for the US Army and the Swiss MOWAG Shark 8x8 vehicle, and proposed for the British Warrior MICV chassis. A shelter mounted version either with on-mount radar for autonomous use, or without radar for coordination with a central fire control center could be mounted on a 4x4 or 6x6 military truck or installed in fixed locations. This version was purchased by Thailand. A version mounted on the 4 wheel trailer used for the Oerlikon Contraves Skyguard fire control system and without radar, probably intended for integration with Skyguard and Oerlikon GDF 35mm guns, was also proposed.

There was also a proposed naval version called Sea Sprint using the standard 8-missile turret minus the radar, proposed for the close-in anti-air and anti-missile self-defense role.

Oerlikon also suggested a dedicated anti-tank system... ...read more
