   The Honorable Caspar W. Weinberger             114605
   The Secretary of Defense

        Subject: Luestionable Need for Product Improvements
                  to te Army's VULCAN Air Defense Systemq
                  (MASAD-S1-21)

   Dear Mr. Secretary:

        As part of a review of air defense in the North Atlantic
   Treaty Organization's central region, we performed limited
   work on proposed product improvements to the VULCAN air de-
   fense system (PIVADS). This is a congressionally initiated
   program to enhance the near term readiness of air defense
   in the airborne and air assault divisions of the Rapid De-
   ployment Force (RDF). Our work was limited primarily to dis-
   cussions with officials at the Army headquarters and commands
   currently involved in the improved VULCAN program.

        We have two concerns involving the need for the product
   improvement program which we believe should be addressed be-
   fore a decision is made to improve the VULCAN system. Spe-
   cifically (1) will it be effective against the representative
   threat and (2) can alternative systems satisfy the need?
   Accordingly, we recommend that you require the Army to fully
   justify the need for the improved VULCAN before the improve-
   ment program is allowed to proceed.

   VULCAN SYSTEM

        VULCAN was fielded in about 1967 as an interim short-
   range air defense system. According to the Army, the VULCAN
   system has very limited effectiveness. For VULCAN to be ef-
   fective, the target must be hovering or flying a nonmaneuver-
   ing course toward the gun and be within a range of 1,000
   meters. VULCAN provides only a low degree of suppression
   against maneuvering threats.

                                                    (95157)
