Insitu Inc. is an American company that designs, develops and manufactures unmanned aerial systems (UAS).

[citation needed] At the end of the 1990s the company transitioned to the SeaScan concept for imaging reconnaissance from tuna seiners.

With the onset of the Iraq War in 2003, SeaScan turned into ScanEagle, and Insitu focused their efforts on military applications.

[citation needed] Insitu was sanctioned by the Chinese government on December 27, 2024 due to arm sales to Taiwan.

[12] Insitu, with the U.S. Navy, developed the RQ-21A Blackjack to fill the requirement for a small tactical UAS capable of operating from both land and sea.
