Operation Pierce Arrow was a U.S. bombing campaign at the beginning of the Vietnam War. The operation consisted of 64 strike sorties of aircraft from the aircraft carriers USS Ticonderoga and USS Constellation against the torpedo boat bases of Hon Gai, Loc Chao, Quang Khe, and Phuc Loi, and the oil storage depot at Vinh.

This was the start of U.S. air operations over North Vietnam and Southeast Asia, attempting to destroy the infrastructure, war material, and military units needed by North Vietnam to prosecute the guerrilla war in the South. The air operations following Pierce Arrow would swell so that by war's end, the United States bombing campaign was the longest and heaviest in history. The 7,662,000 tons of bombs dropped in Southeast Asia during the Vietnam War nearly quadrupled the 2,150,000 tons the U.S. had dropped during World War II.
