438 SC-497 (originally PC-497) class subchasers were constructed for the USN during WWII to hunt submarines, provide convoy escort, search and rescue services, and provide beach control services for various amphibious invasions. SC-1068 was originally sent to Dutch Harbor AK via the Panama Canal in 1943, She operated along the Aleutian chain out to Kiska and Attu during the clearing of the islands. She was then sent to the South Pacific where she received a battle star for the Invasion of Kwajalein and Majuro. She also ranged out to Guam, Saipan, and Eniwetok.

After WWII ended she was returned to the states and spent two years with the USCG as an Air/Sea Rescue Cutter (this is where she gained the AIR SNIPE name (WAVR-465) - all 70 Cutters were named for birds with the Air prefix).
