Positron Blaster Cannon

Positron blaster cannons are highly powerful weapons used as the main guns of some large warships. They fire beams of positrons, the antimatter equivalent of electrons. When such a beam comes into contact with an object, the positrons and electrons annihilate each other, which in turn causes the target to break apart on a molecular level. A side effect of this process is a burst of highly lethal gamma radiation. Positron blaster cannons include the "Lohengrin" cannons used by the Earth Alliance's Archangel-class assault ships and Orb's Izumo-class battleships and the "Tannhäuser" cannon of the ZAFT battleship Minerva. In addition, at least one Earth Alliance fortification on the Arabian Peninsula has been equipped with a "Lohengrin", and the MBF-P03-2 Gundam Astray Blue Frame Second L can be equipped with a miniaturized "Lohengrin", which is the size of a large mobile suit bazooka.

Positronic Interference
Positronic interference is a side effect of firing a positron blaster cannon within Earth's atmoshere that can be used to launch a vessel into space without use of a mass driver. If positron blasters are fired while a ship is in flight, they can produce a cone of positrons that literally disintegrate the atmosphere in front of the ship, eliminating air resistance and allowing it to achieve greater velocity without the risk of burning up in the earth's atmosphere. However, the procedure is only used as an emergency exit, not the standard procedure
