REVIEW OF THE SDI SPACE POWER PROGRAM The SDIO fiscal year (FY) 1987 and 1988 budgets, future projected budgets, and interviews with staff in the SDIO Power Program Office were used as data to deduce the current SDIO investment strategy

This dilemma is frequently referred to as the "chicken-and-egg syndrome." Consequently, support of the SP-100 program by the SDIO Power Program Officc in the absence of a commitment for a specific space mission shows a farsighted perspective, and this committee strongly endorses that strategy.

Accordingly, this committee strongly encourages the development of generic, scalable space power technologies for the future, but believes that advanced development of specific space power systems should await improved specification of SDI weapons. The SP-100 is an exception, and is justified by its having broad applicability to civil and military space power missions and by its potential for providing experience on how to integrate puIsed-power systems in space.

There is substantial interaction within SDIO between its Power Program Office and its programs dealing with kinetic energy weapons, directed-energy weapons, and sensors, ~ order to provide quaTitative and quantitative guidance for emphasis within the space power program. The committee finds that the SDIO Power Program Office is being responsive to the changing needs of the other SDIO directorates by shaping its program accordingly.

A more detailed examination of the SDIO space power program investment strategy for the FY 1987 and FY 1988 budgets follows. COMMENTARY ON THE SDI SPACE POWER INVESTM1:NT STRATEGY The SDIO space power program budgets for FY 1987 and FY 1988 were reviewed to deduce the current SDIO investment strategy for space power.

If a substantial portion of SP-100 funding can be provided by the DOE and NASA, SP-100 development can proceed without consuming the entire SDI power program budget. The committee strongly encourages SDIO to pursue these project partnerships aggressively to avoid erosion of its power technology development program.

Funding for research on rotating machinery technology for power conditioning grew from FY 1987 to FY 1988 because that technology permits reasonable pulse compression to the millisecond range. The committee understands that current-collection technology is a major

System and system technologies have three explicit subdivisions totaling approximately $12 million. As shown In Figure ~4, most of these funds are to define requirements, conduct surveys, fund program management of the SDIO Power Program Office, obtain pros gram advice, and support the independent evaluation group (IEG)

, the committee recommends a concerted study of the effluent issue to discriminate among power options before selecting the most promising approaches. Of course, if some weapons platforms can tolerate substantial effluent, the improved power-per-unit mass from the open-cycle systems and the reduced reliance on the nuclear option with its associated environmental and survivability problems may justify developing several multimegawatt power options.
