Liberation Day II - The second Liberation Day was an ill-fated cruiser launched in the initial attacks on Trade Federation privateers during the conflict with that organization approximately twenty-five years ago. It was obliterated in its first hyperspace jump and lost with all hands.
Liberation Day III - The third Liberation Day was an Alliance Kuat-9 high-speed transport under the control of Alderaanian personnel in the early days of the battle against the Empire. It evacuated dozens of Senators, dissidents from the press and the arts, and their families, to safety when they were threatened by Palpatine's minions. Weaponless, it was destroyed by COMPNOR saboteurs, and most of the crew was captured and executed. The survivors were reassigned to Naval Group 8, under Corellian command.
The B-Wing was the more experimental, and the more problematic, of the designs. The 99 was, by contrast, built along the lines of the time-tested Imperial gunship, with the passenger section replaced with tracking computers, the wings swept back and the cabin rounded to provide a 360-degree firing arc for the five crew members it could support. Although not as maneuverable as starfighters of the line, the 99 is capable of high speeds with sustained burns, and with a starfighter escort proved capable of providing a serious threat to capital ship operations and a devastating screening vessel against starfighters. In a squadron, which was assembled but rarely due to the small number of 99s in service during the conflict, and with appropriate escorts, the unit was capable of outright destroying all but the largest capital ships in the Imperial fleet.
Other than its maneuverability, the high cost of outfitting a 99 was its chief weakness. Because it could carry a full complement of light and heavy torpedoes, required five crew (though in a pinch it could carry up to 10 in tight quarters), a single 99 cost as much to arm as an entire squad of X-Wing fighters. A New Republic military report estimates that the institutional life of the 99 will be at an end in four years. A replacement heavy starfighter is currently under early development at the shipyards in Corellia.
