A Reflex Warhead was a projectile weapon which used Reflex Technology to boost its destructive power.
In 2006, the Armor-1 was intercepted by Roy Fokker flying the prototype YF-1 Valkyrie. The hijackers launched the ship's complement of SF-3 Lancer fighters to destroy Fokker, but the Veritech fighter easily destroyed them and a salvo of missiles from Armor-1. Fokker was able to close on the bridge of the vessel, destroying it with his gun pod. While the hijackers managed to launch a Reflex warhead at Macross Island before they were killed, it was destroyed high above its intended target by Fokker during re-entry through Earth's atmosphere.
