Hull classification

The United Nations Interplanetary Navy uses a hull classification system to identify and categorize various types of voidfaring craft. These classifications are based on the size of the ship, as well as the task the ship is designed to fulfill.

Military Warship Classification

DE Destroyer Escort (1,000 - 1,750 tons)

Destroyer escorts are small, fast, and maneuverable warships intended to engage missiles, strikecraft, and other small threats. Despite what the name implies, it is not uncommon for destroyer escorts to operate independently or in small task groups. Command of a destroyer escort is typically granted to newly promoted commanders (OF-4).

Class	Operator	Tonnage	Armament	Commissioned	Built	Active
Surigao	UNIN	1,450	Missile	11 March 2031	8	7
Samar	UNIN	1,400-1,450	Missile	18 March 2031	12	10

DD Destroyer (1,750 - 4,000 tons)

Destroyers are small, fast ships primarily intended to engage other ships. Command of a destroyer is typically reserved for experienced commanders (OF-4) and captains (OF-5).

Cape Town	UNIN	2,150-2,250	Missile	11 March 2031	12	12
Irkutsk	FEAN	3,900	Unknown	21 July 2036	5	5
Nanuchka	FEAN	3,900	Unknown	9 October 2036	1	1

CL Light Cruiser (4,000 - 7,000 tons)

Light cruisers are medium, fast warships designed to be the primary combatants in a fleet, or operate as a flagship for a battle group. Command of a cruiser is typically reserved for officers ranked captain (OF-5) or commodore (OF-6).

Class	Operator	Tonnage	Armament	Commissioned	Built	Active
Berlin	UNIN	5,000-5,100	Missile	16 December 2029	5	5
Skory	FEAN	6,000	Missile	23rd January 2030	5	5

CA Heavy Cruiser (7,000 - 11,000 tons)

Heavy cruisers are large, fast warships designed as designed to be the primary combatants in a fleet, or operate as a flagship for a battle group. Neither the UN or Federation currently operates any heavy cruiser. Command of a cruiser would likely be reserved for a senior captain (OF-5) or a commodore (OF-6), or above.

Class	Operator	Tonnage	Armament	Commissioned	Built	Active
Hoplite	K2 Aliens	8,000	Particle Beam		≥ 4	≥ 4

BB Battleship (11,000+ tons)

Battleships are the largest warships, and serve as heavy combatants and flagships of a fleet. No battleships are known to exist, though it is speculated the Federation's premier shipyard has expanded to a large enough capacity to construct one. Battleships would almost certainly be commanded by a flag officer ranked Commodore (OF-6) or above.

FC Corvette

Corvette is a designation operated by the Federation Navy, roughly comparable to the UN's destroyer escort.

Moskva	FEAN	1,400	Meson	10 January 2027	19	16

BM Monitor

A monitor is a slow ship of variable size carrying heavy, long range firepower designed to operate as a strategic defense force. Monitors are currently commanded by flag officers rank commodore (OF-6) and rear admiral (OF-7).

Colony ships carry large numbers of passengers via cryo sleep trays.

FR Freighter

Freighters carry TN minerals, fabricated components, infrastructure and trade goods and possess planetary freight handling systems. Freighters cannot carry missiles, as they require dedicated safety systems. Most freighters in the Solar system are operated by civilian shipping corporations.

Transport

Transports carry ground forces into combat zones and unload them at their destination. If equipped with drop pods, they may perform boarding actions. The Federation has historically been dependent on the UN for troop transport capability.
