The Army gave Raytheon Co. [RTN] a contract to provide heavy anti-tank, precision assault missiles for the military, a pact worth an initial $163.2 million that contains a potential five one-year options.

Raytheon will deliver the new wireless version of TOW missiles that receives commands from the gunner through a wireless data link, eliminating the wire connection that the system has used since it was introduced more than 30 years ago.

The weapon works with existing launch platforms, including the Improved Target Acquisition System, Improved Bradley Acquisition Subsystem, TOW 2 Subsystem and M220 Ground TOW.

While operating in a new manner, the system performs exactly as the wire-guided version, enabling soldiers to continue using the proven weapon without changing tactics or incurring additional training.

TOW remains the Army and Marine Corps’ primary heavy anti-tank and precision assault weapon deployed on more than 4,000 TOW launch platforms including the Army “Stryker,” Bradley Fighting Vehicle System and the High Mobility Multipurpose Wheeled Vehicle, or Humvee.
