The ?Black Knights? of Helicopter Antisubmarine Squadron Four (HS-4) ?train like they fight,? extracting naval aviators from hostile territory under the cover of darkness and with the use of night vision equipment. Two helicopters, manned by five personnel each, are used for the training, and if called upon, for an actual mission. The Black Knights are attached to Carrier Air Wing One Four (CVW 14) aboard USS Abraham Lincoln (CVN 72). U.S. Navy photo by Lt. Troy Wilcox.
