Spanish Juan Carlos I Amphibious Carrier (L61):

At the time it was built, Juan Carlos I amphibious carrier was the largest warship ever build for the Spanish Navy and no larger vessels were built for several decades. The ship was laid down in 2005, launched in 2009, and commissioned in 2011. It was in many ways the flagship of the Spanish Navy for many decades.

The vessel was designed to act as both an aircraft carrier and amphibious support ship. Unlike United States amphibious carriers, the vessel was fitted with a ski jump. In the carrier role, it was originally designed for up to thirty aircraft originally including the AV-8B Harrier, V-22 Osprey, and various helicopters. For the amphibious role, it was designed to be able to carry up to nine hundred troops and almost fifty tanks. Four LCM or a single LCAC could be launched from the stern well deck. The ship also was fitted with extensive medical facilities including a full operating room. The vessel was also designed to be able to act as an evacuation and disaster relief ship.

Capable of twenty-one knots, propulsion was combined gas turbine and diesel connected to electrical propulsion pods. Range was 9,000 miles on diesels at fifteen knots. The vessel was built with a high degree of automation and required an extremely small crew for its size. Main air search radar was the Indra Lanza-N 3D search radar. There were some problems with the radar initially but these were able to be solved. No sonar was carried although the vessel did mount sonar decoys.

While initially armed only with four point defense mounts to reduce costs, space was set aside for a Mk 49 RAM missile launcher mount. The launcher was added to the ship in a later refit towards the end of the Twenty-Tens to improve missile defenses. In addition, the AV-8B Harrier was later replaced with the F-35B Joint Strike Fighter. While larger than the Harrier, the F-35B was stealthy, capable of mach speed, and far long ranged. In virtually all respects, the F-35B was a far more effective.

Originally, there had been some consideration given towards building a second amphibious carrier but never came to fruition. At the time, the Spanish navy also had the Principe de Asturias aircraft carrier. Still, the carrier was quite a bit smaller and could carry a more limited aircraft compliment especially the larger F-35B when it replaced the Harrier. The Principe de Asturias was faster, around twenty-six knots compared with only twenty-one knots.

When the revolution in material technology in the Twenty-Thirties, the Spanish Navy found itself virtually obsolete. It was decided that the Juan Carlos I amphibious carrier would be rebuild while the much older Principe de Asturias aircraft carrier would be retired. Newer ships were generally retained and rebuilt while older vessels were retired. Similarly, the Álvaro de Bazán class frigates were retained while the less capable Santa María class would be retired. The initially rebuilding was simply to rebuild the hull with high strength composites and alloys and replace the ordinance with the far more powerful new explosives. At the same time, one of the point defense gun mounts was removed and replaced by a second Mk 49 RAM Missile launcher.

A later upgrade was the complete rebuilding of the propulsion system. The diesel engines and gas turbine were replaced by a single fusion turbine which produced almost twice as much power as the original propulsion system. At the same time, the electrical propulsion pods were rebuilt so that they could handle the far greater power of the fusion plant. Top speed went from twenty-one knots up to twenty-six knots. In addition, the fusion turbine gave virtually unlimited range. There was a smaller emergency fusion turbine also fitted in case the primary power plant went down.

Around the same time as the ship’s power plant was rebuilt, the F-35B Joint Strike Fighter was replaced by the FV-38 Panther II fighter. In addition, new fusion powered versions of the Osprey Tilt Rotor replaced conventional versions of the aircraft embarked. Due to the larger size of the aircraft, fighter compliment was reduced to twenty-four for the original thirty. Part of the rebuilding of the vessel included the virtually removal of fuel tankage and magazine space was able to be greatly increased. At the same time, the amphibious carrier began embarking two hundred PA-04A SAMAS Power Armors.

Eventually it was decided that the retired Principe de Asturias aircraft carrier would be replaced. It was still much smaller than most of the American carriers but far larger than the Principe de Asturias. About the same size as the American Avenger class escort carrier, in many ways it could be considered an enlarger version of the Juan Carlos I amphibious carrier with the well deck and amphibious facilities deleted. Named the Princessa Isabel, it was laid down in the late Twenty-Fifties and completed in the early Twenty-Sixties. It took over the main flagship role from the amphibious carrier. A second carrier was later ordered as well and completed around Twenty-Seventy.

When the second carrier was completed, the Juan Carlos I was relegated to reserve status and training. Still, it was considered too useful to retire completely and was well maintained. There were also no amphibious vessels in the Spanish Navy as capable as the Juan Carlos I although just before the coming of the Rifts a new amphibious carried had been laid down. The new amphibious carrier was scheduled to enter service around 2104. At that time, it is most likely that the Juan Carlos I would have been retired. It is most likely that the new vessel was completely destroyed. It was in this status that the Rifts had overtaken the Juan Carlos I. Nobody is quite sure what happened to her. It is quite possible that the amphibious carrier survived if properly sealed.

[1] If all both elevators are destroyed, no aircraft can be moved from the hangers to the main flight deck.
[2] If the flight deck is destroyed, only VTOL aircraft can be launched or land. VTOL aircraft are at -15% to piloting.
[3] If Bridge / Superstructure is destroyed, the ship can still be piloted from engineering but with a -15% to piloting rolls. Communication and sensor equipment are not concentrated on the bridge to reduce the effectiveness of bridge hits.
[4] Destroying the long range radar system will destroy the ship’s main fire control systems but the vessel has backup systems with a shorter range (Equal to robot vehicle sensors)
[5] Depleting the M.D.C. of the main body destroys the ship’s structural integrity, causing it to sink. There are enough life preservers and inflatable life boats to accommodate everyone on the ship including marines.

Surface: 29.94 mph (26 knots/ 48.18 kph)
Range: Unlimited due to fusion engines (needs to refuel every 15 years and requires maintenance as well). Ship carries six months of supplies on board.

Statistical Data:
Length: 757.2 feet (230.8 meters)
Draft: 23.0 feet (7.0 meters)
Width: 105.0 feet (32.0 meters) including flight deck
Displacement: 23,500 tons standard and 27,200 tons fully loaded
Cargo: 4,000 tons (3,628.7 metric tons) of nonessential equipment and supplies. Each enlisted crew member has a small locker for personal items and uniforms. Ship’s officers have more space for personal items. Extra ammo, armor, troops, weapons, and engines take up most of the ship’s spaces.
Power System: Originally conventional diesel and gas turbine propulsion (CODOG), converted to a single main nuclear reactor with a small backup reactor (both have an average life span of 15 years.)
Market Cost: Not for sale but if found on the black market would probably cost 500 million or more credits.

Weapon Systems:

  1. Three (3) Meroka SPG-M2B 20 mm Close In Weapon Systems: Mount is unusual in that it uses twelve fixed barrels instead of a rotary barrel like the Phalanx CIWS. Modified to fire 20 mm Ramjet Rounds instead of standard rounds. The weapon systems are still quite effective at destroying incoming missiles and are fully automated. The weapons can be used on surface targets as well as against missiles and aircraft. Each autocannon mount can fire on automatic at up to six targets per melee (Has +3 to strike missiles and +2 to strike aircraft).
    Maximum Effective Range: 5,000 feet (1,524 meters)
    Mega-Damage: 2D6x10 for a burst of 60 round (2D4 for each round but gun always fires in bursts).
    Rate of Fire: Six bursts per melee for each mount (Has +3 to strike missiles and +2 to strike aircraft).
    Payload: 720 rounds (12 bursts) each. Ship carries an additional 12,000 rounds of ammunition in magazines. Auto Cannon requires 2 minutes (8 melees) to reload by properly trained personnel (Double for untrained crews).
  2. Two (2) GDC Mk 49 Rolling Airframe Missile Quad Launchers: Vessel was refitted with two of these missile launchers. These are a Pre-Rifts RAM missile launching system and has been modified to use 21 Short Range Missiles. These missile mounts main purpose is for inner anti-missile point defense and was originally designed to deal with cruise missiles. Short Range Missiles are usually a mixture of 50% Armor Piercing and 50% Plasma. Launchers can lock onto multiple targets at the same. The systems missile launchers can target up four targets and can fire a volley up to twice per melee.
    Maximum Effective Range: As per short range missile type (See revised bomb and missile tables for details.)
    Mega Damage: As per short range missile type (See revised bomb and missile tables for details.)
    Rate of Fire: Can fire missiles one at a time or in volleys of two (2) or four (4) missiles and can be used up to twice per melee.
    Payload: 21 missiles each.
  3. Four (4) Chaff Launcher: 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 25% 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.)
    Range: Around Ship
    Mega Damage: None
      01-35 - Enemy missile or missile volley detonates in chaff cloud - Missiles are all destroyed.
      36-60 - Enemy missile or missile volley loses track of real target and veers away in wrong direction (May lock onto another target.)
      61-00 - No effect, enemy missile or missile volley is still on target.
    Payload: 24 each for a total of 96.
  4. Four (4) Towed Decoys: A special decoy which is towed behind the ship. The Coalition has not seen a need for this system so has not equipped their ships with it. It generates a sound like the ships propellers in order to confuse incoming torpedoes. Only effective at speeds below 18 knots. Otherwise, the noise of the ship’s systems and propellers is too powerful to mask. Rifts Earth decoy systems are assumed to not operate on Phase World missiles due to technological difference.
    Effects: The decoy has a 65% chance of fooling ordinary non military sonars and non smart guided torpedoes, the decoy has a 35% chance of fooling military level sonars (like those of the Coalition), and the decoy has a 10% chance of fooling advanced military sonars (Like those of the New Navy and Triax) and smart torpedoes.
    Decoys have a duration of 30 minutes (120 melee rounds)
    Payload: One, with four more as reloads. It takes three minutes (twelve melees) to reel out another decoy.
