A combined force unit of the Union Defence Force, comprising vessels of the Caspian, Krittish, and Yari navies. The Third Fleet was founded in the fourth year of The Crest, and its sponsor was Her Honorable Senator Aly Soussamon. The fleet's nickname was the Iron Torch Fleet, and was often dispatched to patrol the regions of Caspia's frontier that were closest to the Perlemian Trade Route. Because of this, the forces of the fleet found themselves tackling pirates and raiders on a frequent basis, and those pilots that distinguished themselves became aces and masters of their trade.
