X-Plane 9.70+ North American T-2 Buckeye. The North American T2 Buckeye was the United States Navy's intermediate training aircraft, intended to introduce US Navy and US Marine Corps Student Naval Aviators and Student Naval Flight Officers to jets. This is a conversion of the author's original v7.63 Buckeye to v9. You will find three versions of the aircraft: T-2A - U.S. Navy - this is the single engine version, T-2C - U.S. Navy - twin engine version and the T-2E - Greek Air Force. The instrument panel is the same as the previous v7 version, so quite basic. By Davide De Marchi.
