The PL-7 is a reverse engineered Matra R550 Magic WVR AAM, which entered production during the 1980s. The basic Magic I occupies the same niche as contemporary Sidewinders, but the missile uses a characteristic paired canard arrangement to improve turn rates. The seeker is nitrogen gas cooled using a Joule-Thompson element.
While the PL-7 has been displayed at airshows, there have been no reports of significant production numbers or exports. The R550 was exported to India for the Mirage 2000.
