The APEX is designed to defeat a multi-spectrum of target types ranging from air targets to both soft and armored ground targets. It has an explosive filled warhead, with a delayed initiation, so the blast, fragments and incendiary effect are delivered inside the target. A penetrator in the nose gives enhanced penetration capabilities. The APEX is designed specifically for the F-35 fighter, but it may also be used on platforms with a M242 Bushmaster gun.
