Background
The LY83 Fox Light Multirole Utility Vehicle is a military 4WD designed and built created by the Protectorate of Lyras. Specifically designed as a replacement for the M998 and M1114 HMMMV, it has also supplanted a number of similar vehicles, and assumed a wide variety of combatant and non-combatant roles, within all arms of the Lyran Protectorate Military. In most cases, the LY83 is referred to simply as the “Fox”.
The Fox was designed by the Protectorate Research and Development Commission, in conjunction and spurred on by submissions from Asgarnieu and the Federal Republic of Hamilay, both of whom sought Lyran assistance in the production of a light multirole utility vehicle. The Fox is designed primarily for strategic and tactical mobility with a high level of protection against anti-tank and anti-personnel mines, further featuring modular and adaptable armour protection and low observability design.
In peacekeeping or peace enforcement operations, currently undertaken by heavy armour and infantry fighting vehicles, the Fox provides a lower profile while still providing a high level of crew protection. In high intensity conflicts, the Fox can be configured as a scout, command vehicle, ground surveillance radar carrier, ambulance or weapons platform.
Armament
The can mount up to two lateral grenade launchers. Each launcher, as per Lyran standard, is electronically-fired, and consists of four barrels which can be intermixed with either smoke, fragmentation or chaff grenades. The smoke grenades are capable of shrouding the Fox from visual or thermal detection, and the chaff grenades are utilised as a means of breaking up the vehicle's radar cross-section.
Two gunrings are included integral to the chassis, which can be fitted with any number of weapons systems, including, but not limited to; TOW, Spike or Javelin firepoints, LY60, M2 or KPV heavy machine guns, or MG3, LY64, LY19 or M60 GPMGs. The gunrings are compatible with all standard remote weapons systems, should such an option be sought.
Networking, and sensory system
The Fox uses the Cromwell II fire control and battlespace integration system as the basis of its electronic and information warfare suite. Like the Cromwell before it, the Cromwell II system inputs and actively seeks information from a wide variety of sensory sources, including gun-station datastreams (where applicable including, but not limited to, thermal or daylight gun sights, laser rangefinders, automatic crosswind sensors, pendulum static cant sensors, ammunition type and temperature information, and a high-precision muzzle reference sensors).
Cromwell II system follows on from its Inter-Vehicular Information System (IVIS) conceptual ancestor, and is part of an integrated and adaptive battlespace network that maximises combat lethality, and enables command and control on an unprecedented scale. Information is sourced not only from multiple sources on the individual vehicle or soldier, but from every Cromwell II equipped friendly platform within the battlespace, which provides constant informational updates across a broad spectrum of sources, both known to the operators, and operating below their awareness.
The Cromwell II system is often utilised to compute a firing solution, based upon analysis of the target. This is achieved in less time than it would take the gunner to depress the firing stud or authorise the missile launch. The firing solution that Cromwell II generates ensures a near-perfect hit percent at standard ranges, across all conditions.
However, at the most basic level, the Cromwell II system aims to accelerate engagement cycles and increase operational tempo at all levels of the warfighting system. This acceleration is acheived by providing a mechanism to rapidly gather and distribute targeting information, and rapidly issue directives. Cromwell II's ultra-high speed networking permits error-free, high integrity transmission in a bare fraction of the time required for voice-based transmission, and permits transfer of a wide range of data formats, from a multitude of compatible sources.
The Cromwell II links for the Fox use frequency-agile radios or landline. Over 4,000 frequencies with 20kHz channel spacing are used in the frequency agile radio link. The system architecture provides full duplex data exchange and simultaneous half duplex voice communications.
Well implemented networking, using the Cromwell II system, can contribute to improved effectiveness in other ways as well. Rather than micromanage Cromwell-equipped platforms with close control via a command link tether (such as a radio), networked platforms are given significant autonomy, defined objectives, and allowed to take the initiative in how they meet these objectives. The size, integration and scope of the networked Cromwell II system enables all units across the battlespace to respond faster than their opposition, and this increased tempo generates increased lethality across all levels of the engagement spectrum.
The Cromwell II system can automatically detect and track visible or otherwise located targets, compare them using the data link established with other friendly vehicles to prevent redundant target overkill. Parameters for engagement in this instance are determined by the operational rules of engagement, and while functional, although the system does NOT replace the human operator.
The system, in its entirety, is fully insulated against electronic interference and data-hacking, and all communications and information exchange programs are 512 bit encrypted to ensure maximum network security.
Armour and protection
The armour protection on the Fox is adjustable to threat level by the replacement of armour packs within the vehicle's external skin. The basic add-on armour pack provides ballistic protection against small arms fire and a heavier kit provides protection against ambush including mines.
Fuel and ammunition are located within anti-spalling sub-compartments, with integral blowout panels and kevlar liners, although steltexolites are used, as on the Wolfhound tank, as spalling to protect the internals of the crew compartment, given its greater resilience to armour piercing AT weapons.
The protective concept borrows heavily from the British Panther, and is based on creating the maximum distance and protection between the seat of a mine explosion and the cabin. The wheel stations are located away from the crew cabin so that if a wheel detonates an anti-tank mine, the explosion is vented upwards, leaving the crew cabin relatively undamaged. Further, the bonnet is hinged to the chassis to reduce the shock transmitted to the cabin.
The light alloy rear body is fitted with a lightweight kevlar roof over a supporting frame. The rear body is sacrificial and severs from the cabin in the event of a mine detonation under a rear wheel, again leaving the crew cabin intact.
A number of features have been incorporated into the design to protect the cabin from an explosion of an underbelly mine. The underside of the vehicle is v-shaped, an increasingly common adaptation, and the ground clearance has been maximised (at 50cm, by default) to allow maximum dissipation of the blast, with an eye towards crew protection.
The presence of heavy components under the cabin floor has been minimised as these can be forced through the cabin floor by a mine or IED blast. The lower part of the vehicle has a collapsible triple-layered structure that compressed in the event of an underbelly detonation, absorbing a high percentage of the energy that has not been vented away laterally by the v-form hull.
The cabin further includes anti-mine and anti-blast internal features to reduce residual and secondary explosive effects on the crew. There are two adjustable anti-mine front seats and three foldable anti-mine back seats. The seats are not fixed directly to the floor which thereby avoids direct transmission of any explosive shockwave to the crew.
The cabin is fitted with a high resistance roll bar, a two-piece tiltable windscreen and an optional canvas roof with a dismountable frame, should the impact resistant hardtop not be selected for a given situation. The four crew doors are all fitted with sliding and dismountable windows and are built to withstand the shock wave of an explosion, as well as small arms fire.
Propulsion and mobility
The Fox is powered by a LY694 multifuel propane-injected, inter-cooled twin turbo-charged 8L V8 diesel-electric hybrid, generating 350hp at 2000RPM. This grants a horsepower to ton ratio of 87.5.
The Fox, like the LY219 Ironheart features an electric transmission system (the drive shafts have been replaced by cable and the power from the engines is transferred by cable), which delivers a number of advantages, including volume efficiency, very high fuel efficiency, reduced lifecycle costs, and reduced environmental impacts.
The new electric drive has also greatly improved low observability characteristics in terms of thermal and acoustic signatures as well as low visual and radar signatures. The silencers and the exhaust manifolds are installed within the C-spars of the vehicle chassis and the turbocharger is installed under the engine in order to minimise thermal radiation.
The Fox's engine is unique amongst extant hybrid engines by providing the driver with the option to use the added energy provided by the hybrid systems to give vehicles a power boost, rather than the conventional significantly improved fuel efficiency (compared to non-hybrid, traditional diesel counterparts). The trade-off between added performance and improved fuel efficiency is partly controlled by the software within the hybrid system and partly the result of engine, battery and motor sizing. Lyran Arms has facilitated this user control interface through what is in essence an efficiency/power toggle, similar to those on many commercial ICE vehicles.
The 2m width and 5 ton weight of the vehicle allow the vehicle to be air transported to the area of operations by a number of aircraft including the C160, EH101 (two vehicles), C-27J, C-130J (two vehicles) and on heavy lift helicopters CH-53 and CH-47 (two vehicles), in addition to a very large number of NS-grade transport assets.
The vehicle has a maximum road speed of 140kph (87.5mph) and the range is nearly 600km. The Fox is further able to navigate 0.5m steps and cross side slopes of 30% and gradients of 65%. A removable steel cable winch allows independent recovery should the Fox get into difficulty.
The Fox can ford water obstacles to a depth of 0.85m without preparation and with minimal preparation can ford rivers to a depth of 1.5m. The assisted-air hydraulic braking system allows the vehicle to tow loads of up to 5 tonnes.
Crew Amenities
While a comfortable vehicle, the Fox doesn't possess quite the same degree of it that is featured in several heavier Lyran vehicles, due in part to vastly differing roles.
The Fox does however contain the ubiquitous drink point, providing hot water, cold water, and with two further compartments that can be filled with hot or cold drinks of the crew or unit's choice. As well as being morale boosting, hot water in particular can be of direct military value, with it being used to brew tea or coffee, produce other hot beverages and, most importantly, it is used for dehydrated ration packs common to many armies and armed services. The water itself is stored below the vehicle, and acts as additional protection from mines or IEDs.
As Lyran standard, the Fox's integrated NBC system serves as air conditioning/climate control, allowing for working temperatures easily adjustable to every national or personal need (operating temperature range -40C to 55C).
Seat warmers/coolers are also fitted, to ensure greater comfort and optimise combat endurance and deployability. The seats can also be adjusted, manually or electronically, to ensure optimum comfort and control access for any shape or size.
Foxes are, again as per Lyran standard, equipped with integral high-speed wireless (satellite) broadband internet connections, piggy-backing on the Cromwell II connection, allowing the crew to surf the internet, check their emails, or correspond with family. The provision of insulated external connections allows accompanying dismounted personnel to simply plug in to the side of the vehicle, and then they to can go online.
Export
Export versions are identical to Lyran versions, with most of the Lyran cryptographic and communications equipment being memory erased to prevent compromise. All are, however, still integratable into a single force, should the requirement to synchronise operations on a multinational basis arise. Further modified and/or specific custom versions of the LY83 Fox are available from the Lyran Protectorate, with costs altering as circumstances warrant.
Asgarnieu, Verenberg, TPF, Errikland, Bomble, the Federal Republic of Hamilay and and select other nations are eligible for special dispensation, if they wish to utilise the Fox.
Each LY83 currently exports for NS$100,000. Purchases can be made through Lyran Arms (http://forums.jolt.co.uk/showthread.php?t=541320).
