From the release:
The time for action has come. The sixth wave of expansions for Star Wars™: Armada is now available!
Comprised of the Imperial Light Carrier Expansion Pack and the Hammerhead Corvettes Expansion Pack, Armada Wave VI hits far above its weight class with its surprisingly potent starships and an array of upgrades focused on close-quarters combat.
Imperial players gain a medium-base ship that elevates their squadron game to new heights, making it easier than ever to wipe out Rebel fighters with your TIE swarms. More than this, the Quasar Fire-class cruiser-carrier even makes it possible for your TIE swarms to chew through your opponents' ships' defenses, leaving them completely vulnerable to the thunderous volleys of lasers and missiles unleashed by your Star Destroyers. And the ship itself is no slouch either; it can even equip and discard a set of Disposable Capacitors to surprise opponents with heavy volleys of red and blue dice from long range.
Against this threat, the Rebels respond with their Hammerhead corvettes. Built as tough as they appear in Rogue One, these Hammerheads arrive to the game in pairs, and you can use their new Task Force Antilles and Task Force Organa Title upgrades to synchronize either their defense or attacks. Or you can simply take advantage of the ship's strengths as a straight-forward combatant and ram it right into your opponent's ship, using the Garel's Honor Title to ensure you get the better of the collision.
