Inverting Cost Equation

Imposing higher costs on adversaries

Satellites today are launched via booster rocket from a limited number of ground facilities, which can involve a month or longer of preparation for a small payload and significant cost for each mission. Launch costs are driven in part today by fixed site infrastructure, integration, checkout and flight rules. Fixed launch sites can be rendered idle by something as innocuous as rain, and they also limit the direction and timing of orbits satellites can achieve.
Military aircraft have evolved to incorporate ever more automated capabilities, improving mission safety and success rates. Yet operators of even the most automated aircraft must still manage dauntingly complex interfaces and be prepared to respond effectively in emergencies and other unexpected situations that no amount of training can fully prepare one for.
National Security Space (NSS) assets, critical to U.S. warfighting capabilities, traditionally reside in geosynchronous orbit to deliver persistent overhead access to any point on the globe. In the increasingly contested space environment, these exquisite, costly, and monolithic systems have become vulnerable targets that would take years to replace if degraded or destroyed. DARPA’s Blackjack program aims to develop and demonstrate the critical elements for a global high-speed network in low Earth orbit (LEO) that provides the Department of Defense with highly connected, resilient, and persistent coverage.
The general-purpose computer has remained the dominant computing architecture for the last 50 years, driven largely by the relentless pace of Moore’s Law. As this trajectory shows signs of slowing, however, it has become increasingly more challenging to achieve performance gains from generalized hardware, setting the stage for a resurgence in specialized architectures. Today’s specialized, application-specific integrated circuits (ASICs) — hardware customized for a specific application — offer limited flexibility and are costly to design, fabricate, and program.
DARPA’s Experimental Spaceplane program (formerly known as XS-1) aims to build and fly the first of an entirely new class of hypersonic aircraft that would bolster national security by providing short-notice, low-cost access to space. The program aims to achieve a capability well out of reach today—launches to low Earth orbit in days, as compared to the months or years of preparation currently needed to get a single satellite on orbit. Success will depend upon significant advances in both technical capabilities and ground operations, but would revolutionize the Nation’s ability to recover from a catastrophic loss of military or commercial satellites, upon which the United States today is critically dependent.
