The launcher was capable of a full 360 degrees traverse and +90/-9 degrees of elevation. Four missiles were carried on the launch rails, with eight extras stored below the launcher with their fins and wings removed. The gunner sat between the missile pairs on the mount, aiming using a simple reflex sight. An auxiliary power unit provides the necessary power to run the mount, and a cryonic air cooler provides the missile seekers with the necessary cooling. On early model the power unit was a two-cylinder 10 horsepower gasoline engine, though it was replaced with a more powerful 30hp diesel engine in the early 1980s, greatly improving available power while simultaneously allowing fuel compatibility with the main engine.
