Douglas A3D/A-3 Skywarrior (known as Whale by the crews) was largest, heaviest and one of the longest serving carrier-based aircraft in the history, entering service in 1956 and being retired in 1991.
Initially designed and used as a carrier-based strategic and nuclear bomber, it was quickly rendered obsolete by the SLBMs, and it spent the majority of its service life in secondary and support roles, as an electronic warfare platform, tactical reconnaissance aircraft, and aerial refueling.
