USS Thomas G. Kelley (DDG-140) is the 90th planned (Flight III) Aegis guided missile destroyer of the United States Navy. She will honor Captain Thomas G. Kelley (USN, Ret.), who as a then-lieutenant serving in Vietnam, was awarded the Medal of Honor "for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty". Kelley served in the Navy for 30 years, and after retirement, went on to become Secretary of the Massachusetts Department of Veterans' Services.
The keel plate signing ceremony, with the ship's namesake Captain Thomas G. Kelley in attendance, was held at a General Dynamics Bath Iron Works facility in Brunswick, Maine, on 30 August 2024.
