Full Specifications

KC-135 Stratotanker Air Refueling Aircraft

The KC-135 Stratotanker is one of the most important force multipliers in U.S. air power. First introduced during the Cold War, this aircraft gave the U.S. Air Force the ability to project air combat power across continents without relying on forward bases. Even today, it remains a backbone of global air refueling operations.

Manufacturer and Origin

The KC-135 Air Refueling Tanker was developed by Boeing in the United States and is based on the company’s early jet transport designs. It entered service in 1957 and became the first jet powered aerial refueling tanker in the U.S. inventory. More than eight hundred aircraft were built, with many still flying after major upgrades.

Role and Capabilities

The primary mission of the KC-135 is air to air refueling using a flying boom system. It can refuel fighters, bombers, reconnaissance aircraft, and allied platforms. Some variants are also equipped with probe and drogue pods, expanding compatibility with NATO and partner aircraft.

Performance and Technology

Powered by modernized turbofan engines, the KC-135 cruises at high subsonic speed and offers intercontinental range. It can offload over ninety thousand pounds of fuel on long range missions. Avionics upgrades have added digital flight decks, GPS navigation, and improved communication systems. While not armed, the aircraft relies on escort fighters and mission planning for protection.

Operational Use

The KC-135 Air Refueling Tanker has supported every major U.S. military operation since Vietnam, including Desert Storm, Enduring Freedom, and current global deterrence patrols. Despite its age, continued upgrades have kept it operationally relevant as the KC-46 gradually enters service.
