In its January 1998 report, the Task Force recommended that a modified STARLITE program be initiated, as a "Military Space Radar Surveillance Program," in an effort to achieve broad-area, all-weather, near-continuous radar access that could be integrated with military operations. In February 1998 DARPA, the Air Force and the NRO established a joint program to undertake a "Space-based Radar Risk Reduction and Demonstration Program".

126:'s Small Satellite Review Panel concluded that: "...now is an appropriate time to make a qualitative change in the systems architecture of the nation's reconnaissance assets... We see the opportunity to move towards an operational capability for the country, at least for imagery systems, that consists of an array of smaller, cheaper spacecraft in larger numbers which is at least as useful as those currently planned and to transport them to space with substantially smaller and less costly launch vehicles."
