The Lians needed to rely on stealth much more than their predecessors. The hull was a streamlined racing-boat design to slide through the water and to reduce radar cross-section. Near the bow the bridge was built into the hull. Slanted windows on three sides gave an excellent view of the surrounding seas. The ships had a straight flight deck configuration with a ski-jump at the forward edge of the flight deck. A small island structure on the starboard side housed the flight operations center. Both elevators were mounted on the starboard side with one directly in front of the island and the second behind the VLS launcher. These were inboard elevators to and although they cut into the available deck space, they were essential to giving the Lian class a stealth profile.
The Lian class mounted the SPY-6S light-weight radar system with the four fixed panels mounted in the superstructure. At first, designers planned to mount the panels similarly to the Saratoga class on the sides of the hull but water tanks test showed that spray during high speed cruising and during high seas would interfere with the panels. There were plans to upgrade this to the RNEC SPY-6J system, but those plans were lost on December 22, 2098. A hull sonar was planned into the initial design to ensure defensive submarine detection, but was deleted later on as it was deemed unnecessary and space consuming. The class mounted a single 48-cell Mk 59 VLS launcher behind the island. This launcher used medium-range missiles almost exclusively to provide self-defense for the carrier. Four Mk 44 combination missile/railgun defense systems were mounted at the corners of the ship for close-in defense. At first, retractable mounts were considered but were dropped in later design phases. Of course the carriers carried decoy, chaff and jamming systems for self-defense.
A pair of powerful fusion reactors powered the engines, which were mounted in trainable pods under the hull. The propellers were both variable pitch allowing for faster changes in speed and the ability to turn quicker. All this provided for an incredible ship handling capability. Both the hull and propellers were designed with a bubble masking system to reduce ship noise. This was combined with the hull being covered by a sound absorbing rubber material and the engines being specially mounted to reduce noise. The entire hull was constructed of non-corrosive, super-strength materials to ensure protection from both weather and weapons.
The carriers were not equipped with catapults or arrester gear. The carrier had a ski-jump on the bow to allow VTOL aircraft to carry heavier payloads on takeoff. The carrier was designed for ASW and convoy escort rather than for strike missions. The vessels carried a full squadron of 14 Sabertooth VTOLs for attack and defense. Eighteen E-1s were stationed aboard for ASW, EW/ES, COD, AEW, and Airborne Refueling missions.
Model Type: Lian-class Escort Aircraft Carrier
Vehicle Type: Ocean, Escort Aircraft Carrier
Crew: Ships Crew: 395 (55 Officers and 340 Enlisted [Has a high degree of automation]) Air Wing: 345 (120 Pilots, 20 flight deck officers, 205
enlisted)
Speed: 47.2 mph (41 knots/ 76 kph)
Range: Unlimited due to fusion engines. Ship carries six months of supplies on board.
Length: 775 feet (232.5 meters)
Draft: 31.5 feet (9.6 meters) including sonar dome
Width: 184 feet (56.3 meters) including flight deck
Displacement: 22,200 tons standard and 27,900 tons fully loaded
Cargo: 1,000 tons of nonessential equipment and supplies. Each enlisted crew member has a small locker for personal items and uniforms. Ships officers have more space for personal items. Most of the ship's spaces are taken up by extra ammo, armor, troops, weapons, and engines.
Power System: Nuclear Reactor, average life span is 20 years
Weapon Systems: Four (4) Mk-44 Sea Sabre Combination Anti-Missile Defense Systems: Weapons are mounted on the sides of the ship with two on either side of the ski-jump and two on the sides just forward of the fantail. This anti-missile defense system combines both a rapid fire rail gun and a short range missile launcher. While mounted in one system, both defense systems have separate tracking systems. The short range missile launchers can target up four targets and can fire a volley up to three times per minute. The rail gun is capable of destroying any missile or inflicting serious damage on aircraft. The rail gun can fire on automatic at up to six targets at a time. The system also can be used against other ships and ground targets. The system has a 360 degree rotation and can elevate up to 90 degrees to fire at targets directly overhead. Maximum Effective Range: Rail Guns: 11,000 feet (2 miles / 3.2 km). Short Range Missiles: depends on the missile being used Payload: Rail Guns - 8000 rounds (200 burst) each. Short Range Missiles - 16 short range missiles each. Mk-59 Vertical Launch Missile Launcher (1): This launcher is mounted directly behind the island. The system is similar to the vertical launch system employed on many ships in the late twentieth century to launch the SM-2 series missile but since the missiles are smaller they have a reload system that reloads from under the launcher and can reload within 15 seconds. The launcher has a total of 48 individual cells and is six missile cells long by eight cells wide. The launcher can fire up to half its total payload per minute. The launcher can use a vast variety of missiles including surface skimming missiles and rocket propelled torpedoes. Each cell can carry one long range missile or two medium range missile. The reload for the cell must carry
the same load as the main cell. Long range missiles are normally used against large targets and aircraft further out where the medium range missiles will
normally be used to engage closer targets. About half of all long range missiles carried are fusion warheads and most missiles are normally smart missiles. Payload: 48 missile cells in launcher with reload systems for each cell (1 reload each cell). One long range missile or two medium range missiles may be carried per cell but reload must be the same load out as well. The ship will usually carry all 48 cells with two medium range missiles each. Chaff Launcher (2): Located on the superstructure of the ship, they are designed to confuse incoming missiles. Both launchers must be operated or effects will be reduced. Advanced Towed Decoys (4): The vessel carries four advanced towed decoy drones. They are each a small automated vehicle that creates a false sonar image designed to mimic the vessels. The decoy is dragged behind the carrier using a cable.
Special Features: SPY-6S Three Dimensional Search Radar System: While not as powerful as those systems design for missile cruisers, the light-weight system is still quite effective. The system is a powerful and flexible phased array radar system that is comprised of four panels that each emit radar waves. If allowed by the horizon, the system can track out to 250 miles (402.3 km) and can simultaneously track and identify up to 512 targets at one time. The system controls missile launched from the long range missile launchers and the system track and guide each individual missile to an individual target for up to 128 targets. If a target is eliminated, missiles are automatically guided to a new target. The system can also control missiles launched from other linked vessels as well and can also act as fire control for gun mounts. Sonar Masking System: The ship uses water bubbles to form a barrier against sonar as well as a shrouded propeller and sound absorbing materials. Gives a 10% fault to any Read Sensory Instrument rolls to detect this ship using sonar. Command and Control Facilities: The carrier carries extra communications equipment and command facilities, to enable the ship to operate as the flagship for a flotilla. Radar Defeating Profile & Radar Absorbing Materials: The ship superstructure is designed so that the radar profile of the ship is reduced and the ship is covered with radar absorbing materials. Because of this, attempts to detect the ship using radar are made with a 30% fault to read sensor rolls when attempting to detect this ship. Combination Radar Detectors and Active Jamming System: Combination of radar detection system (ESM) and an active jamming system. The system can detect another radar system at 125% of the range of the transmitting radar. Beware however, because when it is active other vehicles bases can detect that it is jamming, and some missiles will home in on jamming signals.
Market Cost: 2.5 billion
