The Blackjack (RQ-21A) was deployed last year. For the Navy and Marine Corps, it fulfills a requirement for a small tactical unmanned aircraft system (STUAS) to follow-on to the ScanEagle. And it is the first military drone that is open architecture, that is, based upon a non-proprietary operating system, allowing it to integrate almost any payload, as long as it complies with the 25 pound limit and the power capacity (called size, weight, and power or SWaP).
