Callahan-class Battleships are massive, fully featured mobile bases. They pack enough firepower to devastate enemy naval vessels and their crew, or rain death on nearby shorelines while shrugging off punishment with its reinforced hull. Named for Caoiva's founder and first Archon, who famously held fast in conflict with rival clans who wanted his head. Several Callahans remain anchored at Whedon's Row Harbour.

— In-game description
The Callahan is a Warden Callahan-Class Battleship. It is equipped with 3 Dual 150mm turrets, 2 Dual 120mm turrets, 2 Heavy Machine Guns, 4 30mm deck guns and 2 AI Naval Turrets.
Controls the movement of the ship, and can see the remaining fuel in the tank, the speed in knots, and the azimuth of the ship in degree.
Can see the distance and angle to the closest repair location (Dry Dock).
Cannoneers (Gunners) x5
Control the movement, reload, and firing of the 120mm and 150mm cannons.
Switch the gun between indirect and direct fire mode with Shift + F
Secondary Gunners x6
Controls the movement, reload, and firing of the 12.7mm machine gun and 30mm deck guns
Spotter
Can view 230m in every direction with distance and azimuth displayed.
Can act as the ship commander to direct the other crew members.
Engineer
Not an actual seat
Switches each of the two ship engines below deck between "Forward" and "Reverse" mode using a Wrench while crouching
Can view the status of an engine by pressing E next to it.
Loaders x2
Not an actual seat
Retrieve shells from the ammo rooms below deck to load them in the 120mm and 150mm turrets inventory.
The entrance area for each seat is marked on the floor by white paint.
Additional soldiers can be on the ship's decks for various purposes (transport, helping load guns, bail water in bottom deck, fix leaks, etc...). The ship can have a total of 30 players onboard, any more and it cannot cross region borders.
Armament
2 x 12.7mm Machine Gun
Mounted on the elevated platforms on the port and starboard side of the ship (150 degree firing arc)
Fire Rate: 27.3 per minute (reloading after each shot); Salvo of 2 in 0.2 seconds
Magazine Size: 2
Accuracy: 2.5m radius at minimum range up to 8.5m at max range (not including Wind effect)
Can also be used in direct fire mode (Max Range: 45 meters, cannot adjust elevation)
3 x Twin 150mm Cannon
One is mounted forward-facing on the large front turret, the other two are rear-facing on the center and rear turrets (can rotate 280 degrees), turns 15° per second)
The ship also has two AI Naval Turrets on its deck that are only active when anchored. They rapidly shoot Mortar Shells at smaller ships (i.e. not Large Ships) and amphibious vehicles on water that are between 75 and 200 meters from the turret, except if the targets are within 35m of a region border.
Inventory
At the front of the bottom deck, the ship has an ammo room with a single inventory slot and a stockpile that can hold 300 items but only accepts 120mm shells, 150mm shells, and Metal Beams. The room looks similar to a Storage Room however the shells can't be retrieved from it with V and the mixing of different ammo types is allowed. Crates of 120mm and 150mm can be directly submitted to it.
At the center of the bottom deck, the ship has another ammo room with a single inventory slot and a stockpile that can hold 600 items but only accepts 120mm shells, 150mm shells, and Metal Beams.
At the rear of the bottom deck, the ship has a 15 slot inventory and a large stockpile. The stockpile is identical to a Base stockpile, except the amount of 120mm shells, 150mm shells, and Heavy Oil is artificially limited to 5.
Each armament on board also has its own separate inventory with just a single dedicated ammo slot for the relevant ammo types: 30 magazines for the 12.7mm Machine Guns, 2 shells for the twin 150mm and 120mm cannons, and 50 shells for the 30mm deck guns.
Can ram and instantly destroy ice on frozen bodies of water during Snow Storms
Cannot move while anchored.
Turn Rates
The drivers direction, engines direction, and application of the handbrake influence the turn rate. For quick reference:
Setting the engines in opposite directions and driving forward allows the ship to turn at its fastest rate of (64.7° per minute).
Using the handbrake, with engines in the same direction, driving forwards, and holding A or D (Left or Right)results in a slower turn rate (16.9° per minute).
Use of the previous configuration, without handbrake results in a slightly slower turn rate (16.8° per minute) but at a significantly higher speed (10.1knots).
Without collision, it's not practical to turn 25° or more while moving forwards or reverse at top speed. Considerable engine manipulation and handbrake is required to accomplish this within the same region.
With engines operating opposite of each other, use of steering or handbrake doesn't impact the turn rate significantly.
Example turn rates and times caused by driver direction, engine direction, and application of the handbrake are detailed in the table below:

Health & Armor
The Callahan has 74750 HP. It has "Large Ship" armor resistance: it can soak small arms fire, shrapnel, 12.7mm machine guns, 20mm anti-tank bullets, and it is immune to Flamethrowers. It's also fairly resistant to Anti-Tank Explosive and Armour Piercing damage. High explosive shells are very effective against it. It has subsystems that have a chance to be disabled by heavy explosives and anti-tank weaponry if hit specifically: Turret/Cannon: 5%, Second Turret/Cannon: 5%. It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 5% chance of penetrating and doing damage. That chance goes up quickly if the armor is worn or if it is shot from up closeor with ammo that has penetration bonuses. As a Large Ship, its health, Tank Armor, and subsystems can only be repaired at a Dry Dock, costs 10 Naval Shell Plating, and takes some time.
Sinking Mechanic:
With their massive health, large ships are hard to kill the normal way, but they can also be sunk.
Interactions
Friendly soldiers in the water can instantly climb aboard the ship with E while next to it.
You can drop items on the ship decks.
The ship has 4 Gangway ramps that can be toggled with E. The anchor must be lowered and there must be solid flat ground for the gangway to deploy (Shipyard, Beach, docks, Dry Dock, Navy Pier, etc...).
The ship's bottom deck contains 4 rooms separated by bulkhead doors which can be toggled with E. Closing a room's bulkheads prevent water from leaks from spreading to the adjacent rooms.
Water in the ship rooms can be bailed using a Water Bucket (reloading) and thrown overboard.
The ship can be reserved for a Squad (via a button in the menu) to prevent any non members from toggling the ship's anchor or changing the engine settings and to allow members to eject any player from the driver seat with the "Eject Driver" button in the menu . The reservation doesn't prevent other friendly players from using the ship's seats or accessing the ship's stockpile however.
Anchor
The anchor interaction area is marked by an arrow at the front of the ship on the Port side (left).
Respawn
Battleships allow players to assign their "Forward" Spawn Point via a button in their menu and respawn on the ship when they die if the ship's main stockpile has Soldier Supplies. Like other Forward Bases, interacting with it updates the player's Map Intelligence.
Deployment
Players can also deploy onto Battleships from the Home Region if they're not within 150m of the region border and if there is not too many players with their spawn set there.
Region Borders
The ship can cross a region border with up to 30 players on board, provided the destination would not exceed its population capacity; otherwise the ship must wait in queue. While preparing to cross the border, the ship must be idle for 60 seconds. Moving, firing any ship weapons or interacting with its stockpile resets this timer.
Must be fully researched in the Vehicle Tech Tree in order to be produced.
Storage & Transport
The Callahan cannot be stored in a Storage Depot, Seaport or Storage Ship. It can be anchored anywhere. It cannot be packaged or transported by another vehicle. As such, it must be driven to its destination, regardless of where it is.
Tactics
Due to the Callahan class's cost and inability to fend off submarine threats it is suggested that it should be escorted by a blacksteele class frigate or a decent gunboat support fleet at all times. (gunboats are ineffective against submarines when they are submerged so frigates are advised for this role)
When engaging an enemy battleship the Callahan class must always attempt to keep it's broadside to the enemy due to the placement of it's main guns, it's forward fireing arc is ineffective and will get you out DPSed by the Titan class's superior forward firepower in a head to head engagement
Trivia
The Callahan-class battleship takes inspiration from the design of pre-WWI capital ships. HMS Dreadnought, which discarded earlier designs that relied on volume of fire in favor of an all-big-gun main battery with a few smaller weapons to keep torpedo boats away, seems to be the major inspiration, but elements of French, British, and German designs from the end of the 19th through the early 20th centuries are all present.
The aft hull includes a stepped-in appearance. In real battleships, this would be to allow for casemate guns in the hull, but none are present here. It's possible that in the lore, these ships were originally designed with guns in these positions in mind, but they were removed for the same reasons they were in real life, namely a tendency to let water into the ship and ineffectiveness in any conditions other than a dead calm with the ship anchored. The role they would have played (keeping small boats away and supporting the main battery at close range) is accomplished by the 30mm guns.
There are two "Battleship" board games sitting on bunk beds of the bottom deck.
With Engines set opposite of each other, the driver pressing S for reverse, and holding Space for the Handbrake - it take over an hour to make a single 360° Turn. (1 hour 32 seconds!)
The Callahan Battleship is unique among large ships with its turn rates; While traveling forwards, use of the handbrake results in a turn slightly faster than without.
