After finishing A-school, PR's will be assigned to their first duty station. This will likely be a Sea-Duty tour, however some personnel are assigned to a shore unit. A sea tour may require working with an F/A-18 Hornet squadron or on an aircraft carrier. Shore tours involve supporting sea-going commands at facilities around the world including NAS Whidbey Island, NAS Jacksonville, Naval Station Norfolk, Naval Station San Diego, NAS Lemoore, Naval Support Activity Bahrain and others. Most PR's will perform the inspection and repair of Aviation Life Support Systems equipment that includes life preservers, life rafts, parachutes, oxygen hoses and regulators, ejection seats, radios, medical equipment and supplies, safety flares, mountaineering equipment, cold weather equipment and other items related to the survival of aviators who may eject or egress from their aircraft in unfavorable conditions.
