The Brunhilde (ブリュンヒルデ Buryunhirude) is a prototype aircraft, designed specifically for Black Rock Shooter. Presumably incorporating seized alien technology, it is a large gunship capable of VTOL (vertical take off/landing). The aircraft is outfitted with 12 missiles arranged in 4 groups of 3 along the wings and an 8-barreled machine gun situated under the cockpit. It is capable of autopilot without human input.
- Brunhilde (or more specifically, Brynhildr) is the name of a female valkyrie in Norse mythology.
