The A-Darter (Agile-Darter) also named V3E is a modern short-range infrared homing ("heat seeking") air-to-air missile, featuring countermeasures resistance with a 180-degree look angle and 120-degrees per second track rate, under development by South Africa's Denel Dynamics (formerly Kentron) and Brazil's Mectron, Avibras and Opto Eletrônica. It will equip South African Air Force's JAS 39 Gripen and Hawk 120; Brazilian Air Force's A-1M AMX, F-5BR and future FX-2. It is expected to be operational in both Air Forces by 2014 and it will also be available for export.
