BOSTON. MA – A Coast Guard helicopter crew assisted with the medical evacuation of a civilian crewman who experienced medical complications while aboard a submerged U.S. Navy submarine conducting sea trials about 77 nautical miles south-southwest of Cape Cod Tuesday afternoon.
The fast-attack submarine, USS Pittsburgh (SSN 720) resurfaced after the 25-year-old Portsmouth, N.H., Naval Shipyard employee began having neurological problems. He was safely transferred via small boat to the Navy submarine support vessel Carolyn Chouest and continued to receive treatment by Pittsburgh’s corpsman. A crewman aboard Carolyn Chouest contacted the Coast Guard about 12:10 p.m. to request a medical evacuation of the victim.
An HH-60 Jayhawk helicopter from Coast Guard Air Station Cape Cod arrived on scene about 1:45 p.m. and hoisted the crewman. He was taken to the airport in Hyannis, Mass., where EMS was waiting for further transport to Cape Cod Hospital.
His condition is unknown.
