This massive class of battleship was first introduced only a few years before the Dominion War. The Breen had long been testing their new energy-draining weapon and had fitted the first Voh Lanthe Battleships provided an excellent platform for the first live-fire testing. The success of the Voh Lanthe during those early tests reaffirmed the Breen’s interest in burst beam weaponry.
The Voh Lanthe Battleships served with distinction during the Dominion War. Participating in lightning strikes deep into Federation and Klingon space, the battleships were capable of besting every ship that they came across – even the Federation’s vaunted Galaxy Command Ship. Unfortunately for the Breen, the Voh Lanthe Battleships became priority targets for the Allies and within four months all three active battleships had been forced back to Breen space for repairs. Subsequent allied counter-offensives effectively isolated the Voh Lanthes from combat for the remainder of the war.
At war’s end, there were still very few warships capable of combating the raw firepower of the Voh Lanthe Battleship. The Federation Sovereign and Klingon Negh’Var were two of only a handful of ships that could make that boast.
