The Hammerhead is the most numerous missile used in the last three decades. As the premier dogfight missile of the post-2015 UEDF and UEEF, the Hammerhead has more kills to its name than any other missile, and is arguably the most important missile in service today, carried on almost all mecha, aircraft and other vehicles. Built as a cylindrical body with a raised seeker section and narrowing thrust port, the Hammerhead is based on the Zentraedi Maggot Universal Dogfight Missile, which equipped the Quaedluun-rau Power Armors and the various Glaug configurations. Like its inspiration, the Hammerhead is small enough to be carried in large numbers. Compared with the Zentraedi missile though, the Hammerhead has almost double the range and a far more advanced seeker head. Two warheads are available for the missile; one, a conventional high explosive warhead, is most often used against mecha, the other warhead, a plasma design, is more commonly used against ground targets. However, both missiles have been used against all manner of targets. The Hammerhead is capable of locking onto off-angle targets after emergence from an internal launcher or launch tubes, and thus mixes flawlessly with helmet- mounted sights despite requiring a lockon-after-launch routine. The first versions of the Hammerhead were the Hammerhead A, with a high explosive warhead, and the Hammerhead B, which was the same missile, fitted with a plasma warhead. The UEEF developed a slightly updated version on Tirol, with an improved seeker head incorporating an UV element, which gave enhanced detection capabilities against Invid mecha thrusters. The improved Hammerheads were the C and D models, once again only differing in their high explosive/plasma warheads. The Southern Cross, not fighting the Invid, kept using the A and B versions until the return of the UEEF relief fleet. After that, in anticipation of possible Invid attack, the Southern Cross switched production to the C and D variants as well. However, at the time of the Invid Invasion, most SC stocks were still of the A and B versions.
