QF-99B Dart

The FQ-99B Dart was an atmospheric and exoatmospheric-capable, twin-engine, carrier-capable, unmanned combat drone (UCA/SV) designed by Chevron Aerospace and operated by the United Nations Space Command. The Dart, a modernised variant of the Human-Covenant War-era nicknamed the Wombat, featured several advancements over its predecessor including a vastly improved central processor, which allowed it to match and exceed the performance of most sentient pilots, as well as be remotely operate by an AI; advanced variable geometry three-stage hybrid engines, which could function as turbofans, scramjets or rocket engines; and a threefold increase in payload capacity. The Dart functioned as an unmanned support vehicle, being used to supplement ground or spatial forces in combat and acting as an effective yet somewhat more disposable companion to manned fighter craft.
