 Navy aircraft take off and land every day but no one wants to hear that an aircraft has crashed. When the unthinkable does happen you won't hear about the sailors behind the equipment saving lives. Aircrew survival equipment or PRs are the survival equipment specialists who oversee the valuable life-saving equipment used by naval pilots, air crewmen and other Air Department personnel. The PR rating was established in 1942 to help meet parachute survival requirements during World War II. The original title of the rating was parachute rigor but as sailors took on more responsibility and as more life-saving equipment was developed the rating title was changed to aircrew survival equipment. Despite the 1965 title change aircrew survival equipment maintained their official abbreviated title of PR. So next time you see a fighter jet or the leapfrogs land at a baseball game remember the model of the PRs working behind the scenes. The last to let you down.
