Variously known as Alto or Derby, this Israeli active radar-guided air-to-air missile (AAM) is a collaborative effort between Rafael, the state's armament development agency, and Israel Aircraft Industries MBT. Officially acknowledged in 1998, the project has been underway for at least a decade. This missile's design shares considerable commonality with Python 4, though adding mid-body wings. This medium-range weapon, with a maximum effective engagement envelope of about 50 km, may have already entered service with the Israeli Air Force. Israel is marketing a variant of the missile for export, with offers to the Philippines and India, while South Korea and China also be potential customers.
