Overview
Bainbridge (CGN-25)
USS Bainbridge (DLGN-25/CGN-25) was the first nuclear-powered guided missile cruiser in the U.S. Navy, serving from 1962 to 1996 across various global theaters. Originally designated as a destroyer leader, it was reclassified in 1975 and participated in significant operations, including the Vietnam War and various missions in the Mediterranean and Atlantic, showcasing its advanced capabilities and strategic mobility.

Research Notes

First nuclear-powered frigate/cruiser

USS Bainbridge was built as a nuclear-powered guided missile ship to escort carrier task forces without refueling limits.

USS Bainbridge began life as DLGN-25, a nuclear-powered guided missile frigate or destroyer leader, and was later reclassified CGN-25. Naval History and Heritage Command identifies her as the third U.S. Navy ship named Bainbridge and records her long service career. The ship was part of the early nuclear surface-combatant era, intended to operate with nuclear-powered carriers and maintain high-speed endurance across global deployments.

Nuclear propulsion with missile combat systems

Bainbridge combined two nuclear reactors, Terrier missile launchers, ASROC, guns, sensors, and later Harpoon upgrades.

Bainbridge's design paired nuclear propulsion with guided-missile escort capability. Nuclear power removed the need for frequent refueling, while missile launchers and sensors allowed fleet air defense and anti-submarine support. The ship's later upgrades reflected changing threats and weapons. She was not as large as later cruisers, but her propulsion and combat system made her a major step in U.S. surface-fleet experimentation.

Three decades of global escort duty

Bainbridge served from the Vietnam era through post-Cold-War deployments, proving both the promise and cost of nuclear surface escorts.

In service, USS Bainbridge operated across the Mediterranean, Atlantic, Pacific, and Indian Ocean, including Vietnam War-era and later deployments. Her value was endurance and integration with carrier groups, but nuclear surface combatants were expensive to build and maintain. The ship's career is therefore useful context for why the U.S. Navy eventually concentrated nuclear propulsion in carriers and submarines rather than most escorts.
