handle is hein.gao/gaobabdwf0001 and id is 1 raw text is: This is an unclassified digest furnished in lieu of a report containing classified security information. REPORT BY THE SWINGER POST AIR DEFENSE MISSILE: COMPTROLLER GENERAL --POTENTIAL PRODUCTION PROBLEMS OF THE UNITED STATES --PLANNED IMPROVEMENTS DIGEST The Army has just completed development of the Stinger POST air defense missile, which pro- vides better performance in coping with certain threats than an earlier version of Stinger now in production. Stinger POST is portable and shoulder-fired and uses the same airframe, motor, and warhead as the existing Stinger mis- sile. Stinger POST's improved performance is due to its use of infrared and ultraviolet detectors to acquire and home-in on enemy aircraft--a new seeker referred to as the passive optical seeker technique (POST). The entire Stinger program encompasses the development and production of about 50,000 mis- siles of which 40,000 will have the POST seeker. The reported estimated program acquisition cost is about $4.3 billion. (See pp. 1 and 2.) Production uncertainties exist which could significantly affect program cost and delay procuring the quantity of missiles desired. The uncertainties relate to the difficulty of producing the ultraviolet detector and other critical seeker components in sufficient quan- tities to permit a high rate of production. The manufacturing processes tried so far have produced very low yields of high quality materials and components. Unless the yields can be increased, the quantity of missiles the Army hopes to obtain will cost more and take longer to produce. Consequently, the Army has awarded a contract to refine the processes going into the manufacture of high quality cadmium sulfide crystal, and ultraviolet detec- tors produced from the crystal. Also, the Army will try to effect more economical production of microelectronic chips and printed circuit boards in a production proofing phase (to vali- date the adequacy of production technology) to begin in March 1983. The success of these efforts is critical to full-scale production of the seeker. 1 GAO/C-MASAD-83-10 4 -_ -)JANUARY 26.,1983 120564U
