A U.S. Navy crewman wears a sound-powered headset while on duty aboard the aircraft carrier USS Ticonderoga during the Vietnam War. Headsets like this one allowed flight deck and bridge personnel to communicate clearly amid the roar of jet engines during round-the-clock air operations. The catwalk safety netting visible behind him was a standard feature along carrier flight decks, protecting crew working near the ship's edge during launch and recovery cycles. Project: 218112
