The main components of a photon torpedo consist of a photon/anti-deuterium reactive warhead placed into a Terminium-reinforced casing, commonly known as a photon tube. Before detonation, the matter/anti-matter charge is kept separated by an internal magno-plasma force field. Upon detonation, the field automatically deactivates, flooding the reaction chamber. This process allows thousands of magnetic micro-pockets of photons to combine with anti-matter. These micro-pockets help to control both blast radius and blast intensity.
They remained the standard compliment on all ships for over a century. A newer torpedo, called the quantum torpedo, was invented by the Federation around 2371; however, only advanced starships utilized that weapon.
