Battlefleet Koronus - Notable Vessels of Battlefleet Koronus: Gryphon (Mars-class Battlecruiser) This venerable Mars-class Battlecruiser has served with Battlefleet Koronus since its inception, often as the detachment's flagship. Many foes have fallen to its powerful and fearsomely accurate Nova Cannon, until the ship is known, and feared by the Imperium's enemies, throughout the regions of the Expanse near the Maw. Almost as renowned are the Gryphon's Attack Craft squadrons, especially the Fury interceptors of Tempest Wing and the Starhawk bombers of Absolution Wing. Currently, the Gryphon is under the personal command of Fleet-Captain Horne, and consequently patrols between the detachment's staging points.Stormwind (Overlord-class Battlecruiser) - This powerful Overlord-class Battlecruiser is better suited for full warfare than long-range patrols, and some wonder how it ended up assigned to the Passage Watch at all. In truth, Battlefleet Calixis was loath to lose this vessel to the demands of the "Margin Crusade" and the ongoing war in the Jericho Reach, and transferred it to the Passage Watch instead. The Crusade's masters could hardly protest without raising unwanted attention amongst those who do not know the true nature of the Margin Crusade, which is simply an excuse to hide the existence of the Achilus Crusade and the Calixis Sector's role in supporting an Imperial Crusade on the other side of the galaxy. Now, the Stormwind spends much of its time commanding the blockade forces around Zone 15, but provides a powerful reserve should the Passage Watch or Battlefleet Calixis find itself in a full-blown war.Sirius (Lunar-class Cruiser) - A stalwart Lunar-class Cruiser with an impressive record of service, the Sirius fought with distinction in the Battle of Gethsemane during the Gothic War of 143-151.M41, helping to throw back Abaddon's attempted conquest of the Gothic Sector. It was subsequently transferred to Battlefleet Calixis, then to Passage Watch 27-Est. The Siriuss veterans constantly train new recruits, so that the warship's crew has earned a reputation as being particularly competent. The Sirius often patrols the Maw entrance in the company of the Gethsemane.Gethsemane (Gothic-class Cruiser) - Something of a rarity in a Battlefleet, this Gothic-class Cruiser is newly constructed, built within the last century at the Drystan Construction Yards. Its crew is still considered "green," hence its pairing with the veteran Sirius. It is rumoured that Fleet Command finds it amusing to partner the ship with a vessel that fought in the battle the Gethsemane is named for.Hand of Redemption (Lunar-class Cruiser) - Under the command of Captain Keel, this Lunar-class Cruiser spent several years on "extended patrol" in Winterscale's Realm. Upon his return, his familiarity with the Koronus Expanse meant Battlefleet Command felt it was worth transferring him to the Passage Watch.Drake (Tyrant-class Cruiser) - A Tyrant-class Cruiser, the Drake recently returned to service after being trapped in the Immaterium for five years by the violent Warp Storms bordering the Maw. That the warship survived either makes it lucky or suspect, depending on whom one asks.Warspite (Dictator-class Cruiser) - Like most Dictator-class Cruisers, the Warspite began life as a Lunar, and was converted into an Attack Carrier vessel to better serve the needs of Battlefleet Koronus. Its duties alternate between convey patrols around Port Wander, and showing the flag at outposts beyond the Maw.Swiftsure (Dauntless-class Light Cruiser) - Battlefleet Koronus finds Light Cruisers exceedingly useful in anti-piracy patrols, and the Swiftsure is one of several Dauntless-class vessels in the Passage Watch's ranks. Under a succession of aggressive (and slightly brutal) captains, it has become the bane of Cold Trade smugglers who run the Maw.Hawk (Defiance-class Light Cruiser) - Voss Pattern vessels are rare this far from the world of Armageddon, and this Defiance-class Light Cruiser/Attack Carrier is the only one of its kind in Battlefleet Calixis. Light Cruisers outfitted as Attack Carrier vessels are thought of as an unworkable hybrid vessel by many Navy officers, and Hawk was transferred to the Passage Watch mostly because Sector Command was unsure what to do with her. Under the command of Commander Victoria Horne, however, Hawk consistently patrols deep into the Expanse, and has proven a valuable source of intelligence to the Battlefleet.
