Photon charge
A photon charge was an explosive utilized by Starfleet vessels in the 24th century.

In 2371, Captain Janeway suggested detonating a field of photon charges between Voyager and a space-dwelling lifeform which had been attacking the ship. Commander Chakotay, however, suggested using a non-aggressive tactic. ()
