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.

The term 'blackjack' referring to a hand weapon is of unknown etymology, and the earliest text reference is 1889. A type used by sailors in the 19th and early 20th century was weighted with a heavy lead ball at one or both ends of a piece of baleen, which is then wrapped in woven or plaited marline or codline and then varnished over.

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.Blackjack seeks to incorporate commercial sector advances in LEO, including design of LEO constellations intended for broadband internet service, of which the design and manufacturing could offer economies of scale previously unavailable. DARPA is interested in capitalizing on these advances to demonstrate military utility, emphasizing a commoditized bus and low-cost interchangeable payloads with short design cycles and frequent technology upgrades.The key program objectives are:. Develop payload and mission-level autonomy software and demonstrate autonomous orbital operations including on-orbit distributed decision processors. Develop and implement advanced commercial manufacturing for military payloads and the spacecraft bus. Demonstrate payloads in LEO to augment NSS assets.

The driver will be to show LEO performance that is on par with current systems in geosynchronous orbit with the spacecraft combined bus, payload(s), and launch costs under $6 million per orbital node while the payloads meet size, weight, and power constraints of the commercial bus.
