U.S. CGN-81 Charleston class Nuclear Missile Cruiser:
With the aging of the Ticonderoga class, the United States Navy needed a replacement for the vessels which had served well for around half a century. The time which the old missile cruisers were being decommissioned was one of reduced budgets and many politicians felt that the Burke and later classes of destroyers could fill the role. The United States Navy was able to get some funding for development but much less than they wished. The first of the Concord class gun cruisers had just been commissioned and it was selected as the basis for the new guided missile cruiser class. The Charleston was designed with as many features in common with the Concord as possible and in appearance they look very close. A similar design criteria was used for the previous Ticonderoga class cruiser which shared the same hull and lower levels of the superstructure to the Spruance class destroyer. The main change is the reduction in number of gun barrels and increasing the number of missile launching cells.
While the cruiser was under development, Congress changed the naming convention back to the way it was originally. Originally cruisers were named after United States cities but it was changed first to congressional leaders and then to state names. The entire twenty ship class was named after American cities. The United States Congress changed the cruiser naming convention yet again after the Charleston class and the next class, Delaware class, was named after States.
Like the Concord, the Charleston is heavy based on the DD-21 program and shares many of the same features. The missile cruisers actually share about ninety percent of the same systems as the Concord class gun cruisers and shares the same hull and virtually the same superstructure. Like the Concord, the Charleston was constructed from high strength alloys which made it both very tough and virtually immune to corrosion. For these reasons, these missile cruisers lasted far longer than classes that preceded them and were still serving when the Rifts came. The hull and superstructure were designed to give the vessel a reduced radar cross signature. Their main role was as carrier escorts like most previous missile cruisers. Due to this, the ships rarely carried a large amount of cruise missiles even though they have the capacity for them. The Delaware replaced these ships as the main cruisers of the United States Navy but the Charleston class was still considered too valuable to remove from service. The Delaware class is actually slightly smaller and displaces less while having a similar payload of missiles. If any vessels of the Charleston class survived the cataclysm of the coming of the Rifts is unknown but quite possible.
The main changes between the Concord and Charleston are the weapon systems. Instead of triple barrel 155 mm cannons, the Charleston carries single barrel cannons of the same caliber. The weight and volume from the reduction in cannons allowed for the carrying of two thirty-two cell MK-41 missile VLS in addition to the two sixty-four cell VLS. The decks that hold the sixty-four cell VLS are stretched slightly and one of the small VLS is fitted before the superstructure and the other is fitted behind the ship’s stacks and is above the hanger. The ship has 192 VLS cells as compared to the Concord Class having 128 cells. The side mounted Mk-55 medium range missile launchers were retained for medium range point defense. Like the Concord class gun cruisers, these vessels were originally fitted with four RAM missile launchers. They are in the exact same place as on the Concord class as well. Also, like the Concord, these close-in point defense missile launchers were replaced by combination rail gun and short range missile launchers. This system was carried in virtually all United States Navy combatant vessels. These ships also carry torpedo tubes because it is expected that they would be used in anti-submarine warfare. Most of the electronics on the classes are identical but the Charleston carries a more advanced phased array radar system. This radar system was first developed for the Ranger class carrier but was modified for the missile cruiser. This radar system was not quite as powerful as that fitted on the Delaware class missile cruiser but was still considered quite adequate at the coming of the Rifts.
The history of the ships' propulsion mirrors that of the gun cruisers that they are based on. These ships were originally built using powerful Gas Turbine engines powering electric propulsion. These engines gave the ship a top speed of 33 knots. These were replaced by fusion turbines based on those developed for aircraft. The new engines increased the top speed to 36 knots. The vessels were originally designated CG (Cruiser, Guided Missile) but when the engines were replaced, the designation was changed to CGN (Cruiser, Guided Missile, Nuclear). The ship was designed using variable pitch propellers for high maneuverability and also has stabilizers and is a surprisingly stable vessel. The ship is fitted with bubble masking to reduce machinery noise.
Initially, a vast reduction of crew compared to the Concord class was considered. This was eventually dropped for the same reason that it was not considered for the Concord class. Simply, there was concern that they crew would not be large enough in an emergency and would be unable to keep up with operations when the ship was on a wartime footing. The ship still incorporated a large amount of automation and does require a slightly smaller crew than the Concord does. This is mainly due to the lower manning required by the gun mounts. These ships were not fitted as flagships like the later Delaware class cruisers although there were about twenty extra bunks for additional personnel not including the crew for the two helicopters.
These ships initially did not carry any marines onboard but after the beginning of the New Cold War it was decided that some would be carried onboard for defense against boarding and other roles. These marines took up the space for extra personnel and a small section of deck berthing was divided from the rest and was taken over by the marines. The marines generally had about eight flying power armors onboard.

Market Cost: Not for sale but if found on the black market would probably cost 600 million or more credits.
- Two (2) Single Barrel 155 mm Naval Guns: One turret is mounted in the front of the vessel and the other turret is mounted on the rear. Based on the gun carried by the DD-21 class destroyer and shared similarities to army artillery weapons. The weapon is more powerful than the previous 127 mm cannon carried on many destroyers and cruisers. The weapon mount is heavily automated and is capable against other ships, against ground targets, and against aircraft. The weapon can use special artillery rounds, rocket assisted rounds, and can even fire Extended Range Guided Munitions. The turret can rotate 360 and has a 90 arc of fire.
- Four (4) Mk 44 "Sea Sabre" Combination Anti-Missile Defense Systems: One system is on the front of the superstructure, one system on the rear of the superstructure, and one is on either side of the superstructure. 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 twice per melee. 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 per melee (Has +3 to strike missile and +2 to strike aircraft). The rail gun is very similar to those carried on the Sea King Cruiser and it is likely that the Sea Kings rail guns came from a prototype of this system. 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.
- Four (4) Strategic MK 41 Vertical Launch Missile Launchers: The ship has two launchers with sixty four cells and two launchers with thirty two cells. The forward platform, behind the 155 mm gun, contains a 64 cell launcher behind the gun and a 32 cells launcher closer to the main superstructure. The deck above the hanger contains a 32 cell launcher forward and a 64 cell launcher aft. These are the longer strategic version of the missile launcher and can carry the longer cruise missile. From the beginning, the launchers have been found to be very flexible and adaptable. The launcher was originally design for the Tomahawk and Standard SM-2 Missile. On Rifts Earth, the launchers have been adapted to hold one cruise missile, two long range missiles, or four medium range missiles per cell. Cruise missiles are usually used against hardened fixed targets, long range missiles are normally used against aircraft and other large targets, and medium range missiles are normally used against closer targets such as incoming missiles. Normally, the launchers carry all cruise missiles and long range missiles. For close defense, medium range missiles are carried in the Mk-55 missile system
- Mk 55 Vertical Medium Range Missile Launchers (2): Unlike most vertical launch systems, these launchers fire the missiles on a 6 degree angle to the side. This is because the system was initially designed for carriers and is to prevent a missile that fails on its launch from crashing into aircraft on the flight deck. The missiles are arranged in an 2 by 4 pattern, and each launch cell has six reloads. One launcher is mounted on either side of the hull of the cruiser and require much less space than a Mk-41 or MK-49 VLS. Each system can launch up to 8 missiles simultaneously each and the launcher is automatically reloaded. These launchers often act as the ships middle point defense and are normally used to engage incoming air targets and missiles.
- Two (2) Medium Torpedo Launchers: Mainly design for anti-submarine warfare but can be used against surface targets. There is one launcher on each side of the ship with four tubes each. The tubes have an automatic reloading system and can be fired quickly. The ships carries a total of 80 torpedoes for reloads. Treat warheads as medium range missile warheads.
- 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. Reduce effects of launchers by 50% per launcher not used. Rifts Earth decoy systems are assumed to not operate on Phase World missiles due to technological difference. Reduce effects by 20% against smart missiles (Add +20% to rolls for smart missiles.)
Maximum Effective Range: 13.7 miles (11.9 nautical miles / 22 km) for standard projectiles, 23.5 miles (20.4 nautical miles / 36.4 km) for rocket propelled rounds, and treat Extended Range Guided Munitions as medium range missiles (See revised bomb and missile tables for details.)
Mega-Damage: Standard Projectiles: 2D6x10 to a blast radius of 25 ft (7.7 m) for High Explosive, 3D6x10 to a blast radius of 6 ft (2 m) for High Explosive Armor Piercing, and 4D6x10 to a blast radius of 25 ft (7.7 m) for Plasma. Rocket projectiles: 2D4x10 to a blast radius of 20 ft (6.1 m) for High Explosive, 2D6x10 to a blast radius of 4 ft (1.2 m) for High Explosive Armor Piercing, and 3D6x10 to a blast radius of 20 ft (6.1 m) for Plasma. Extended Range Guided Munitions: Treat as medium range missiles (See revised bomb and missile tables for details.)

Payload: 4 Decoys.
The ship has all systems standard on a robot vehicle plus the following special features:
- SPY-4E Three Dimensional Search Radar System Phased array radar system designed originally for the Ranger class carrier and modified for the Charleston class cruiser. The incredibly advanced radar and computer system first developed before the coming of the Rifts and is similar to the system as that which is carried on Coalition Navy vessels. Powerful and flexible radar system that is comprised of four panels that each emit radar waves. If allowed by the horizon, the system can track out to 600 miles (966 km) and can simultaneously track and identify up to 768 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 192 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. The system gives a +10% to read sensory rolls, +2 on initiative, and +1 to strike.
- Advanced Hull Sonar: Mounted under the bow of the ship. Range of 25 miles (21.7 nm / 40.2 km). This hull sonar system has both a passive and active system built in. Sonar system can track up to 32 targets at one time
- Advanced Towed Array Sonar System: The system is basically a long and very sensitive sonar system carried behind the ship on a long cable. Range of 100 miles (86.9 nm / 160.9 km). This towed array sonar system has both a passive and active system built in. Sonar system can track up to 64 targets at one time.
- Sonar Masking System: The Ship uses water bubbles to form a barrier against sonar as well as a shrouded propellor and sound absorbing materials. Gives a -20% penalty to any Read Sensory Instrument rolls to detect this ship using sonar.
- 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 -20% penalty to read sensor rolls when attempting to detect this ship. Go to General Detection Penalties for more information on penalties and bonuses to use with stealth.
- 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. In jamming mode, causes -25% to detection but when it is active, other vehicles/ bases can detect that it is jamming, and some missiles will home in on jamming signals. Jamming also causes a -4 penalty to all radar guided weapons.
