Photon torpedoes

Photon torpedoes' are imaginary weapons used in the Star Trek science fiction universe.

They are essentially 'missiles' with 'matter/anti-matter' warheads capable of very powerful explosions.

When the 'photons' impact on the target the 'matter/anti-matter' components come together exploding with incredible force.[1]

They were later complemented by quantum torpedoes.
