How did it perform?
>>Main gun was the Shillelagh TOW missile.
Shillelagh and TOW missiles were very different animals. Shillelagh used an infrared link back to the launch optics, while TOW uses wires (Tube-launched, Optically-tracked, Wire-guided).
TOW was a much more successful system than Shillelagh. The infrared command link of Shillelagh was high among its many problems.
