In 1997, the United States purchased 21 Moldovan MiG-29 aircraft under the Nunn–Lugar Cooperative Threat Reduction program. Fourteen were MiG-29S models, which are equipped with an active radar jammer in its spine and are capable of being armed with nuclear weapons. Part of the United States’ motive to purchase these aircraft was to prevent them from being sold to Iran. This purchase could also provide the tactical jet fighter communities of the USAF, the USN and the USMC with a working evaluation and data for the MiG-29, and possibly for use in dissimilar air combat training. Such information may prove valuable in any future conflicts and can aid in the design and testing of current and future weapons platforms. In late 1997, the MiGs were delivered to the National Air and Space Intelligence Center (NASIC) at Wright-Patterson Air Force Base in Ohio, though many of the former Moldovan MiG-29s are believed to have been scrapped. Some of these MiG-29s are currently on open display at Nellis AFB, Nevada; NAS Fallon, Nevada; Goodfellow AFB, Texas; and Wright-Patterson AFB, Ohio.
