Background:
Following a request by the Nachmere Armed Forces for a light fighting vehicle for its mountain warfare units, NPS started development of a wheeled AFV. The NAF asked for a vehicle capable of transporting 7 passengers and capable of engaging both infantry and light armor. It also requested the vehicle to be amphibious to allow it to cross rivers and lakes with minimal preparation. NPS chose a 6X6, conventional design and a turret based on the one used for the Lioness HIFV. The result is a light, fast vehicle that carries a considerable fire power.
General layout:
The LIVF-2070 "Viper" is a 6X6 design with the engine set to the front, driver and commander compartments behind it. The gunner is seated behind the commander and passengers at the back of the vehicle. A rear hydraulic door allows troop dismount while protected. The turret is essentially a large remote operated weapons station with its own ammo storage for the 20mm cannon. More ammo is carried inside for both the HLLCRS and 20mm.

Mobility:
The “Viper” is powered by a 290hp, 6 cylinder turbocharged water cooled engine. This engine is coupled to a 6X6 drive system and a semi-automatic transmission with 6 forward gears and 2 reverse gears. The Hydro-pneumatic suspension is adjustable, allowing for a lower, road setting and a higher off-road setting. The 6 wheels have special heavy-duty run-flat tires. A pressure regulating system allows the driver to set tire pressure separately for each tire, and gives warning if the tire pressure s incorrect for the load and speed of the vehicle.
The "Viper' is fully amphibious, propelled in the water by two water jets. Before entering the water a splash vane must be erected on the front of the vehicle and bilge pumps switched on. When the vehicle is on water accuracy of fire is somewhat reduced.

Fire power and observation:
The LIFV-2070 is armed to fight infantry and light AFVs. It carries two major weapon systems in a remotely operated turret/weapons station, as well as a 80mm close range grenade launch system.
1)70mm HLLCRS: The High Lethality-Low Cost-Rocket System was developed especially for the LIFV-2070. The system is based on 70mm rockets that can hit targets as far as 8000 meters away from the vehicle with truly awesome force. There are several warheads available for the HLLCRS: HE, WP, Anti-Personnel Flechette, HEAT (140mm RHA penetration), and Thermobaric. Each rocket pod carries 9 rockets, and the "Viper" carries 5 pods. When a pod is loaded it automatically informs the fire control as to what type of rockets it carries. The gunner can then select to fire a single rocket or a 3 rocket burst. The gunner can select which rockets to fire at what order. To allow fast firing, a default 3 round burst exists for any possible load. The pod continues to update the fire control about available rockets until it is empty. The pod is than ejected, and the commander and gunner must load a new pod.

2)The 20mm automatic cannon gives the LIFV-2070 the ability to engage massed infantry and light AFVs at ranges of up to 2000 meters with deadly accuracy and sufficient suppression, while keeping ammunition stores at practical levels for sustained fighting.
The sights are located in the unmanned turret, and both the gunner and commander can fire the weapons. The Thermal Imaging System (TIS) has magnification x10 narrow field of view and x3 wide field of view. The thermal image is displayed in the eyepiece of the gunner and commander sights together with the range measurement from a laser rangefinder. The Eye-safe Laser Rangefinder (ELRF) has range accuracy to within 10m and target discrimination of 20m.
The fire control computer automatically calculates the fire solution based on: lead angle measurement; velocity measurement from a wind sensor on the roof of the turret; data from a pendulum static cant sensor located at the centre of the turret roof; temperature, and barometric pressure from a sensor on the turret roof.
Solutions to moving targets or to fire-on-the-move are given by measuring the traverse speed of the turret while tracking the target.
The driver has either three observation periscopes or two periscopes on both sides and a Driver’s Thermal Viewer. The periscopes provide 120° field of view. The driver also has a rear view TI camera.


Protection and survivability:
The LIVF-2070 is protected by a combination of spaced steel armor, NERA plates and an active protection system.
Passive Protection: The LIFV-2070 has a spaced steel armor that protects it against light weapons. It also has NERA plates protecting vital areas on the front of the vehicle and troop compartment. The interior of the "Viper" is lined with a Kevlar anti-spalling layer. This passive protection is capable of stopping most kinetic-energy threats of up to 14.5mm caliber, as well as smaller chemical energy threats at vital areas.
Active Protection: The "Viper" is equipped with an active protection system based on fire-control radar and a “hard-kill” launching system. The fire control radar, located on top of the hull, identifies incoming rockets and missiles and classifies them. It than reacts by firing a quick reaction projectile from one of the 20 carried around the vehicle. This projectile engages the threat 50 meters away from the vehicle by detonating on it. The system is reloadable and storage in the vehicle allows for 20 extra projectiles to be carried.
Screening and Decoys: the LIFV-2070 carries 2 8 tube 80mm. grenade launchers on the front of the turret. These tubes can fire IR Screening and IR Decoy grenades to help the tank screen or avoid incoming threats. In addition the "Viper" is equipped with a standard self screening system using condensed diesel fumes.
Fire suppression: LIFV-2070 uses several systems to prevent and suppress fires. The crew and passenger compartment are both equipped with fire detectors and 4 BCF canisters. The canisters are operated either automatically by the detectors or manually by the crew (Commander and Passenger Compartments). 2 more BCF canisters are located in the engine compartment and can be operated from the driver’s controls or from outside the vehicle. The driver and commander have red-light indicators for an engine fire. The diesel fuel for the engine is stored in 4 tanks in the front and back of the vehicle, with cutoff valves allowing the use of each tank separately.
Explosion prevention and protection:Storage compartments for the ammunition are protected by NERA and thicker steel armor. They also have blow out panels, which direct the energy of a possible ammo explosion outside the vehicle. The crew and passenger seats are all of the suspended type, keeping them above the floor in case of an explosion underneath the vehicle.
NBC protection: The "Viper" is equipped with an overpressure system. The system pumps air from outside the vehicle through a system of filters and into to the vehicle, creating an overpressure that keeps contaminated air out if the Viper is fully buttoned. If the "Viper" cannot be fully buttoned, each crew member and passenger can use an individual, pressurized mask with a 90% field of vision. The overpressure system is integrated with an air-condition system but will operate even if that system is damaged.

Communications, Navigation, and Interface:
Internal communications: The LIFV-2070 has internal communications system, with headsets integrated to ballistic helmets. The system allows the commander to choose which crew members he hears and can hear him. The system has a separate commander to driver channel, receiving power from the best protected battery, to ensure the commander can always communicate with the driver. The system also has a wireless ability, which switches on automatically when the helmets are disconnected from the system; this prevents crew members being accidently disconnected and allows for faster dismount drills.
External Communications: The "Viper" is prepared to accept 2 transmitter-receivers and 2 receivers, antenna bases being integral. The antenna bases allow for lowering the antennas forwards and backwards from inside. The "Viper" is equipped with a AFV/infantry telephone located at the rear of the vehicle and connected to the commander’s internal communications.
Navigation: The "Viper" is equipped with an integral GPS navigation system, viewed on the commanders, passenger and drivers LCD displays. The system includes navigation rout planning, point to point line-of-sight checks, battle preplanning and other useful features. The navigation system can be integrated into battlefield management systems and used to give a complete picture of the battle.
Interface: The crew interface of the "Viper" includes a LCD screen/Control for each crew member as well as one for the passengers, clearly showing the information needed. The LCD screen/Control is encased in high-resistance polymer and has buttons allowing control of many systems. These electronic controls are all backed-up by conventional switches and controls in case they malfunction.
Amenities: The "Viper" gives its crew all that’s needed to fight and stay buttoned for long periods. 2 50 liter internal, NBC protected water tanks supplies hot and cold water through a water point. An air-conditioning system connects to the crews overalls to keep them cool while fighting. The LIFV-2070 can hold 4 days worth of rations for its crew.

ooc: Doesn't look like it would seat 8 comfortably[with full gear], since it's shorter then the BTR-70/80[which is a cramped vehicle in my experience.]. It'd be better for 5 or 6 soldiers, who wouldn't have to stow most of their gear on the exterior. Other then that, it seems like a solid vehicle.
