Jaguar was a three-stage sounding rocket developed by the United States Air Force in the early 1960s.

Jaguar was an air-launched sounding rocket developed by the Air Research and Development Command of the U.S. Air Force, intended for use for high-altitude scientific research into the aurora borealis and radiation trapped in the Van Allen Belts.

[2][1] It was to be launched using a Martin B-57 Canberra medium bomber that was modified to carry the rocket on a side-mounted pylon; this allowed for the rocket to be launched from any location capable of operating a jet aircraft, without the need for installing launch infrastructure in remote areas.

[4] To launch, the Canberra would pull into a near-vertical climb, akin to that used for toss bombing, and release the rocket;[2] Jaguar was expected to be capable of launching a 16-kilogram (35 lb) payload to an apogee of 800 kilometres (500 mi).

[3] An upgraded version using the improved "Yardbird" model of the Recruit was proposed.
