Vietnam War: Operation Pierce Arrow: American aircraft from carriers USS Ticonderoga and USS Constellation bomb North Vietnam in retaliation for strikes against U.S. destroyers in the Gulf of Tonkin.

The Vietnam War was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam and South Vietnam and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian and Cambodian Civil Wars, which ended with all three countries becoming communist in 1975.

Operation Pierce Arrow was a U.S. bombing campaign at the beginning of the Vietnam War.

USS Ticonderoga (CV/CVA/CVS-14) was one of 24 Essex-class aircraft carriers built during World War II for the United States Navy. The ship was the fourth US Navy ship to bear the name, and was named after the capture of Fort Ticonderoga in the American Revolutionary War. Ticonderoga was commissioned in May 1944, and served in several campaigns in the Pacific Theater of Operations, earning five battle stars. Decommissioned shortly after the end of the war, she was modernized and recommissioned in the early 1950s as an attack carrier (CVA), and then eventually became an antisubmarine carrier (CVS). She was recommissioned too late to participate in the Korean War, but was very active in the Vietnam War, earning three Navy Unit Commendations, one Meritorious Unit Commendation, and 12 battle stars.

USS Constellation (CVA-64/CV-64) was a Kitty Hawk-class supercarrier and the third ship of the United States Navy to be named in honor of the "new constellation of stars" on the flag of the United States. One of the fastest ships in the Navy, as proven by her victory during a battlegroup race held in 1985, she was nicknamed "Connie" by her crew and officially as "America's Flagship".
