and C-146 (Dornier 328) are militarized conversions of existing civilian aircraft. Transport aircraft are operated by Air Mobility Command, Air Force Special Operations Command, and United States Air Forces in Europe – Air Forces Africa.

Electronic warfare aircraft are used to keep airspaces friendly, and send critical information to anyone who needs it. They are often called "the eye in the sky". The roles of the aircraft vary greatly among the different variants to include electronic warfare and jamming (EC-130H), psychological operations and communications (EC-130J), airborne early warning and control (E-3), airborne command post (E-4B), ground targeting radar (E-8C), range control (E-9A), and communications relay (E-11A, EQ-4B).

Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft, such as the F-117 Nighthawk. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as full-scale aerial targets (FSATs) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF had 2,025 fighters in service as of September 2012. F-15C and F-15D Eagle F-15E Strike Eagle F-15EX Eagle II F-16C and F-16D Fighting Falcon F-22A Raptor F-35A Lightning II H – Search and rescue These aircraft are used for search and rescue and combat search and rescue on land or sea. The HC-130N/P aircraft are being replaced by newer HC-130J models. HH-60U are replacement aircraft for "G" models that have been lost in combat operations
