Hunter-Killer is an unofficial project name based upon an Aviation Week & Space Technology article. The U.S. Air Force's Hunter-Killer program was a tactical unmanned combat air vehicles (UCAV) procurement program. The General Atomics MQ-9 Reaper, a variant of the MQ-1 Predator won the project and was deployed in Afghanistan.

The term “HK” or Hunter-Killer was used in the 1984 film The Terminator to describe autonomous, twin-ducted fan UAS capable of identifying and destroying targets.
