Abstract : The necessity to protect the glass dome window on optically guided weapon systems became a firm requirement with the reports of weapon damage to Fleet-returned missiles. A test program was initiated to determine the range and extent of rain-erosion damage to a typical electro-optically guided weapon system, the Walleye. The developmental end item was a lightweight, open-ended frustum of a cone that attaches to the nose of the weapon. The design met all of the basic requirements for rain-erosion prevention, airborne boresighting, low drag, minor modification to the Walleye system, and simple one-piece deployment.
