Design
The Jericho is a large Multirole Amphibious Assault Ship (LHDN) with a very unique design. Built for maximum capacity, she carries her aircraft hangar in the middle of the flightdeck in the shape of an oversized superstructure. She also has a novel forward island for directing air operations away from the main bridge. The Jericho is built to provide long range transport to thousands of troops and provide combat support when landing them on hostile shores. The size, sophistication and sheer power of the Jericho will ensure she remains the backbone of the Freethinker Amphibious Assault Fleet for many years to come.

The Jericho is 452 metres long, 67 metres wide and has a draft of 13.2 metres. The vessel displaces 210,000 tons fully loaded and has a range limited only by crew endurance. Six months of supplies and equipment can be carried without replenishment carrying a standard crew and airwing only.

The Jericho is the first ship to utilise the new standardised armour plates. Instead of creating new armour schemes for different ships, Freethinker designers have come up with a grading system for standard armour types so that replacement and maintenance is made easier. The Jericho carries grade S2 armour, which is made up of mixed layers of Titanium VA, Ballistic Composite, Cooling Gel and Damage Control sensors that allow for significant protection against most nautical threats. The belt plates have successfully stopped without significant damage almost all light weight sub- and supersonic ASMs carried by many navies.

As with other large Freethinker vessels, to support the heavy frame a honeycomb network of supporting beam and lattices is installed throughout the ship, along with a displaced keel set high in the hull for added structural integrity and protection against torpedoes. The framework is made from Titanium VA, and is interspersed with shock dampeners and anti-splitting brackets. Because of the need for large internal spaces, the framework is not as intensive or encompassing as the scheme fitted in other warships, but still offers extremely significant gains in structural integrity when compared to traditionally constructed vessels.

The ships are outfitted for a crew of 760 with a minimum optimal crew of 620, along with an airwing of approximately 1,600. There are berths for an additional 2,800 overflow personnel and accommodation and equipment storage for up to 3,200 embarked Marines or Soldiers

Aviation
As mentioned above, the Jericho has two large flightdecks located forward and aft of the superstructure. The forward flightdeck handles principle aerial missions, and is fitted with a Seven-degree ski-jump offset to port, opposite the Air Control tower, to support STOVL aircraft in take-off. No catapults or arrester gear is installed, and the split flight deck limits space for landing. The rear flight deck is generally used for aircraft storage and aerial insertion operations only. It is also possible for a limited number of UAVs and UCAVs to be operated from the Jericho in support of amphibious operations.

The main hangar is located in the superstructure located in the middle of the ship. Two sets of armoured doors lead out onto either flightdeck, and within the hangar are the main maintenance, rearming and repair facilities of the Jericho, and full combat operations with helicopters and VSTOL aircraft can be maintained over a significant amount of time. There are also five elevators that lead down to link up the flightdeck with the two vehicle storage decks, and, if the client so desires, more aircraft can be stored on these decks at the expense of vehicles and stores. However, with a normal loadout and spacing, 60 VSTOL aircraft and helicopters can be carried on the flightdeck and superstructure hangar without limiting flight operations.

Guns
The Jericho carries four Oto Melara 76mm/62 Super Rapid Guns, installed in pairs amidship. These guns can fire at up to 150RPM at targets up to 12km. These are principally Anti-Air weapons but can also be used against light surface targets, and are excellent self defence weapons in littoral combat theatres.

The Jericho also carries thirteen Falltech/Ballistics International Mk.3 JOCIWS systems, carried in pairs along the flight deck and on the superstructure, with a single bow mount far forward. These units support both four independently fed 40mm cannons for a maximum firing rate of 3,600 RPM out to a distance of 5km. Up to 18 Short-Range SAM weapons can mounted in the two 3x3 boxes mounted on the unit.

The ship also carries four Ballistics International Automated Dual 25mm GP Cannons, in pairs on either side of the superstructure. These guns can fire up to 6km at up to 800 RPM, and can be either manually or automatically aimed. These are primarily used, like the Super Rapid guns, against littoral aerial and surface threats, and are backed up with a dozen .50 cal machine guns located across the beam walkway.

Laser-Based Weapons
Two Falltech 500 KW Carbon Dioxide ‘Deadeye’ Laser CIWS are mounted, one on either side of the superstructure, and with a lowered laser aimed using a ‘Ball’ mirror assembly, it is a reasonably reliable, fast tracking and engagement CIWS system that has, in trials even engaged targets as small as a 6-inch shell. It has an estimated range of thirty kilometres against aerial targets in good weather conditions.

Missiles
The main missile launching system is the Falltech Mk.72 Multirole VLS in both its tactical and strategic length. Four Sixteen-Cell (2x8) Strategic-length VLS are mounted along the sides of the superstructure. These large tubes can carry a variety of ordinance but are usually reserved for large Land Attack weapons for use in support of an amphibious landing.

Seven Eight-Cell (2x4) Tactical-length are also installed, in three pairs along the flightdeck edge and one forward opposite the forward island. These are smaller launchers, usually armed with SAMs and similar weapons to engage aircraft and missiles, but can carry other weapons as well. In all, a total of 64 Strategic and 56 Tactical Weapons can be carried by the Jericho.

For self-defence against shipping threats, there are two Quadruple launchers for medium range SSMs fitted just to the rear of the main Mack. In export versions this is the Boeing Harpoon ASM, although other weapons can be carried. These weapons are carried primarily for surface threats, particularly FACs and similar vessels that present a threat in littoral combat zones.

Underwater Weaponry
The Jericho carries the brand new Torpedo Intercept System (TIS), a new Eight-Tube underwater launcher for lightweight torpedoes that can be used against localised underwater threats such as torpedoes, mines, divers and close-by submarines. Eight launchers are carried with a total of 64 light torpedoes. The system can engage targets at up to 600 metres from the ship.

The Jericho also carries four Falltech Mk.2 200mm Unguided ASW Mortars. These can fire a variety of warheads against nearby submarine targets. Reload is manual. These simple but efficient weapons have successfully engaged and destroyed both conventional and, with superb effectiveness, super-cavitating torpedoes. These units have a range of up to 2,000 metres although in reactive mode may operate as close as 200-300 metres.

Countermeasures
The Jericho carries six Mk.5 Decoy Launchers from Falltech. These units can fire a mixture of flares and chaff decoys, both mobile and floating, in order to confess and redirect multiple threats. Launchers for the modern SRBOC decoy system are also carried. For use against torpedo threats, a ‘Nixie’ towed decoy system is also carried.

The Falltech Mk.603 Intercept/Jamming system is also installed. The latest in a series of highly effective ECM/ESM equipment, the 603 provides unparalleled support and jamming capabilities for the host warship.

Sensors
The principle surface and aerial detection system on the Jericho is the Falltech APAR-12D I-band LPI radar system. One set of four panels is mounted on the forward Mack, and provide continuous all-weather tracking and targeting of aerial and surface contacts. The system can simultaneously track and engage up to 684 independent contacts up to a range of 396 miles (where the horizon allows), and new software enhancements and ECM support provide excellent counter ability against targets deploying decoys.

The Falltech IRIS (mod 1), which provides over the horizon tracking by utilising the Surface effect and by adapting super-directional arrays to detection and tracking, is installed on the aft Mack, and provides early warning capability for a distance of up to sixty miles. Limited targeting ability against surface opponents is incorporated in the system. The main purpose, however, is to provide early warning of sea-skimming threat, allowing reaction times in the minutes rather than seconds.

Other systems on the Jericho include three Falltech Mk.1 LIDAR arrays mounted on the forward island and the two superstructure Macks; these provide multispectrum tracking and targeting of airborne and surface targets in the systems line of sight. Four Falltech AS-20 Short-Range LPI Radar systems are installed on the forward island and the superstructure for fire direction duties.

Sonar is the standard Falltech SS-24 Active/Passive bow-mounted array, capable of tracking 144 targets out to 30 miles in Active and 120 miles in Passive mode. This is unlikely to be utilised often as the ship’s normal operations would make active and passive scanning difficult.

Command and Control
The main control unit for the Jericho is the Falltech ‘Landmaster’ Ship Control Bloc. This dedicated control suite is designed for amphibious assault vessels and utilises secure data links to maintain communication with aerial and sea based landing units and the landing assault units on the beachhead itself. The system is designed to provide real-time combat information on both 2D and 3D displays, allowing commanders to see the full theatre with the real-time positioning of friendly and enemy forces. The system also hosts the secure data-flows from land units for support fire, and can direct the ships own weapons and provide accurate targeting data for aerial units.

Landmaster can also work very effectively as a sub-unit in the command chain, providing a hub for communications in an amphibious operation and relaying information onto a separate flagship, and in turn relaying orders in the opposite direction. Landmaster communication lines, through all digital and analogue frequencies have been installed with sufficient encoding gear to prevent malicious hacking of communication channels.

The Jericho also uses the Falltech General Ship-based Theatre Defence Control system for back up control and fleet integration, designed to provide full scale multilinking and targeting between multiple ships and can effectively relay information and commands as both a controlling and as a subsidiary command system. In Freethinker Systems the Command/Control bloc supports the Overlord Multilink system, in more conventional navies it utilises and supports AEGIS for this purpose. The system can direct and target all the ships weapons in cooperation with both sub-units and with allied forces, and can interlink with a host of other combat systems when the need arises.

Amphibious Assault
For sea-based amphibious assault the Jericho carries a mixture of modern LCACs with tradition Landing Craft. At the rear of the vessel is located the Jericho’s well deck. However, because the Jericho is designed to operate LCACs only from here, the deck is not floodable as well decks traditionally are. However, this means that in lieu of the hovercraft, vehicles and other stores can be placed here when in overflow.

The well deck is 120.8 metres long and 46.2 metres wide, and can accommodate up to 12 Scandavian ‘Tigershark’ class LCACs in a 3x4 arrangement. This gives significant single-wave landing capability for the Jericho, and the large size of the well deck can accommodate the larger Russian LCACs as well for added versatility. The well deck is located directly to the rear of the lower vehicle deck and tanks and other amphibious assault vehicles can either be driven or crane-loaded on to the respective LCAC.

For additional landing capability, eight LCVs are carried in divots along the forward sides of the ship in protected enclosures. These sturdy, traditionally designed landing craft can land up to 44 men or up to thirty tons of cargo onto a beach and add significantly to the single-wave landing capability of the Jericho.

Accommodation And Cargo
There are 3,200 dedicated bunks for Marines located in the bow of the ship, with more luxurious accommodation for officers and senior NCOs located in the superstructure. The Marine quarters, although crowded, are significantly less cramped than on previous ships and recreational facilities are also extensively fitted. Another feature is the ‘Assault Pathways’ that run through the Marine quarters to the loading bays for sea and aerial insertion, allowing speedy and organised loading in a short period of time. These pathways also aid evacuation in an emergency.

There are two main decks, equivalent to aircraft carrier hangars in shape and size but usually dedicated to vehicle and stores storage. There is a total of 32,500 square metres of storage space, enough room for approximately 650 MBT’s or equivalent, although a weight limit of 35,000 tons does tend to limit this number somewhat. Alternatively, the space can be converted to makeshift accommodation to house even more marines, and additional temporary cooking, recreational and sanitation facilities can be hooked up to the ship’s own systems. Assuming conversion of the rear flightdeck and hangar for vehicle storage, it has been theorised that a full Scandavian Marine division could be carried by a single Jericho, although the concentration of resources in one hull would make a very tempting target.

For movement between decks, both five elevators and two vehicle ramps move between both vehicle decks and the flightdeck. The placement has been made of these to ensure efficient movement of men and material for both aerial and amphibious insertion.

RO/RO
For loading and unloading at an established dockside, two Roll-on/Roll-off sideports have been included halfway along the ship to provide self-sustaining RO/RO capability. Featuring retractable heavy duty ramps beneath folding armour plates, these large 150-ton rated ramps can be adjusted to almost any height for loading and unloading in commercially rated ports and harbours. Another useful feature of the sideports is that when stationary, the ramps can be adjusted and connected with those of another Jericho class, so that vehicles can move from one to ship to another. This is only recommended when both ships are at a dockside for quicker unloading. Whilst moving or with more than two ships, a minor swell or similar can create sufficient strain to rupture and collapse the ramps with obvious results.

There are also two 50-ton rated cranes on either beam on the aft flightdeck, which can be used in a limited Lift-on/Lift-off capacity, as well as being used for aircraft recovery and can also be utilised for very limited underway stores replenishment of escorting warships.

Hospital Facilities
The Jericho is equipped with extensive hospital facilities so it can act as a close casualty receiver for providing immediate aid to wounded Marines and Crew. Six Operating Theatres, three X-ray rooms, an extensive lab, two decontamination suites, a Blood and Organ storage bank, and many other facilities are carried. A total of 80 ICU beds and 300 Standard beds are fitted as standard, though in an emergency more could be set up in one of the vehicle storage areas. These extensive facilities also make the Jericho an extremely useful asset in humanitarian operations.

Propulsion
The Jericho is powered by two Thompson Engineering R-27 175 MW-rated Pebblebed Reactors (license produced Scandavian models) for a combined useable power output of 342 MW at full running. Two Thompson Engineering R-18 50 MW-rated Pebblebed Reactors are installed for emergency power, producing a total of 92 MW in usable power.

The ship has full Integrated Electrical Systems, with power to six Electrical Induction turbines which in turn power three shafts to three sets of dual variable pitch propellers in acoustically shielded housings. Cruising speed is 25 kts and top speed reached on trials has been ~29kts, although this is unlikely to be reached in combat set up. Four 2 MW MHD-driven bow thrusters are also installed for close in manoeuvring.

Export
The Jericho will be offered in export version to allies in the Organisation of Maritime Powers and the New Alliance Treaty Organisation in limited numbers, along with very limited export to nations outside these alliances. The current price for a new build ship is $US 8,000,000,000, with a 5 year construction time.
