Pinch fusion reactors are a form of power generator that can be found aboard Covenant warships. The fusion reactor can also be scaled down and used in smaller weapons systems such as the Type-38 Anti-Aircraft Cannon.
Pinch fusion reactors use artificial gravity generators to initiate and sustain a fusion reaction, replicating conditions inside stars. Pinch fusion reactors generate an enormous amount of power and plasma but are volatile; they detonate with the fury of a small supernova if containment fails.
They use tritium as a fuel source. If their cooling systems are disabled or their maximum heat loads are exceeded, they will fail explosively providing a detonation on a similar scale of UNSC warship reactors.
