The Boeing B-50 Superfortress is an American strategic bomber. A postWorld War II revision of the Boeing B-29 Superfortress, it was fitted with more powerful Pratt & Whitney R-4360 radial engines, stronger structure, a taller tail fin, and other improvements. It was the last piston-engined bomber built by Boeing for the United States Air Force, and was further refined into Boeing's final such design, the B-54. Though not as well known as its direct predecessor, the B-50 was in USAF service for nearly 20 years.

After its primary service with Strategic Air Command (SAC) ended, B-50 airframes were modified into aerial tankers for Tactical Air Command (TAC) (KB-50) and as weather reconnaissance aircraft (WB-50) for the Air Weather Service. Both the tanker and hurricane hunter versions were retired in March 1965 due to metal fatigue and corrosion found in the wreckage of KB-50J, 48-065, which crashed on 14 October 1964.

In the United States Army (USA), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF), captain (abbreviated "CPT" in the USA and "Capt" in the USMC, USAF, and USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version.
