Normally the Kh-31 is carried by the MiG-29 Fulcrum or Su-27 Flanker fighters, including the SU-35 and SU-31 (see above). The Kh-31 is currently being offered for export equipped with either an active or passive RF seeker. The Kh-31 has also appeared under the MiG-31 in an anti-air role, using the passive R/F seeker to home in on U.S. radar planes such as the E-2 Hawkeye or E-3 Sentry. Other possible customers for the Kh-31 include India, Syria, Libya, Iran and China.
