01 Executive_Summary

Strategic Defense Initiative directed energy programs FY1985-1993 (GAO NSIAD-93-182). Programs: (1) Nuclear-powered x-ray laser ('Excalibur') — LLNL, Lowell Wood's O Group, underground nuclear tests. (2) Free-electron lasers — ground-based with space relay mirrors, transferred to Army FY1994. (3) Space-based chemical lasers (Alpha/Zenith Star) — leading candidate for early follow-on, transferred to Air Force FY1994. (4) Neutral particle beams — BEAR rocket test July 1989 at White Sands, LANL-coordinated, first NPB accelerator in space. (5) Brilliant Pebbles — LLNL/Lowell Wood, small spacecraft for boost-phase intercept by collision, SDIO baseline 1990, discontinued 1994. Priority decreased after Soviet breakup (1990) and Bush refocusing (1991). 1992: Congress directed far-term programs transfer to ARPA/military. SDI re-directed Shiva Star from nuclear weapons effects to directed energy research in the 1980s — MARAUDER (1990-1993) was a direct product of the SDI era.

02 Definition
