The US Air Force (USAF) in South Korea has completed the transition of the last Thunderbolt II aircraft A-10A model to the A-10C model.

The new model features improved precision strike capability, and enhances the USAF’s ability to provide lethal and precise close-air support.

The USAF commenced the transition to the new model in early 2010 with five A-10Cs at Osan Air Base, South Korea.

The final A-10A aircraft is being transferred for modification and reassignment to the US Air National Guard.

The upgrade to the C-model combines a highly survivable airframe and air-to-ground cannon with digital sensor and pilot integration.

The upgrades will provide attack pilots with a truly integrated suite of sensors, aircraft and weapons that build situational awareness and facilitate the rapid destruction of targets.

The A-10C is an enhanced version of the twin-engine, single-seat, subsonic, A-10A Thunderbolt II attack aircraft that served as air support aircraft for the USAF, Air National Guard and Reserves.
