Background:

The ATAV-2 started as a private venture by NPS, to create an Anti-Tank Guided Missile launch platform that is both well protected and highly mobile. The project used major components from two previous NPS designs- The TM-2 (http://forums.jolt.co.uk/showpost.php?p=14662495&postcount=275) medium tank and the Hunter (http://forums.jolt.co.uk/showthread.php?t=590528) GLATGM.

From the TM-2 the ATAV-2 borrows its automotive components and hull, while the TLFFR 150 Assassin missile borrowed extensively from the Hunter’s guidance and propulsion. In addition the project required development in guidance and optics for the missile.

Important note- This description has two sections. The first regards the ATAV-2 launching vehicle and the second regards the TLFFR 150 missile system itself. Please read through the entire post.

Section 1: The vehicle

Fire power and observation:

Armament:

A)The ATAV-2 has a retractable, 2 rail launching system for TLFFR-150 “Assassin” ATGM. The launcher is housed in the center of the vehicle, and deployed before firing. Inside the vehicle is a loading system holding 16 more tubes, in two 8 tube carousels. After the two missiles are fire from the tubes on the launcher, the tubes are jettisoned. The launcher arm than lowers in to the hull and two new tubes are loaded.

B)The ATAV-2 has a 7.62mm machine gun in a remote operated weapons station. The Weapons station is retractable and controlled from the “weapons operator A” compartment. It has 270 rounds ready to use and 2700 more are carried internally and can be loaded. The commander’s hatch is located near the weapons station and when he is commanding the vehicle with his head out, he can use the MG manually.

C)A 2X6 80mm close range grenade launching system, located at the front of the vehicle and capable of engaging infantry at close ranges(60 meters). The grenade types fired by the system are: Fragmentation, White-Phosphorus, Less-Than-Lethal “Flash-bang”, Less-Than-Lethal Tear Gas, IR Screening, and IR Decoy.

Observation and sensors

The ATAV-2 has several observation systems. The main observation system is the day and night sight(discussed in detail below). In addition the vehicle also has a wave millimeter RADAR(also discussed below).

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 camera with thermal imaging for night operations.


Mobility:

The ATAV-2 is powered by a multi-fuel 1200hp, twin turbo charged engine, producing 900kw. The engine is located at the back of the tank coupled to a hydro-mechanical transmission. The transmission is semi-automatic with 5 forward gears and two backward gears, as well as a pivot gear.

The ATAV has 6 pairs of road wheels on each side, with helical spring and hydraulic dampers for each pair. The combination of Helical and Hydraulic dampers improves ride comfort over harsh mountain terrain. The tracks are 550mm wide with no rubber soles. Connection between sections is made by a separate pin. This makes for quick section replacement and while pin erosion is high, section erosion is relatively low.

Protection and survivability:

The ATAV-2 is protected by a combination of composite passive armor, Non Explosive Reactive Armor, and an Active Protection system.
Armor: The armor is composite and made of layers of steel, DU (Depleted Uranium), and ceramics. The crew compartments in the TM-2 are lined with Kevlar to prevent spalling. The passive armor is angled and in some parts spaced, to protect against medium(up to 130mm) KE threats at contact ranges.

Reactive Armor: ATAV has spaced, multi-layered NERA (Non Explosive Reactive Armor) plates on most of its hull. The reactive armor suite protects the tank against most CE threats.

Active Protection: The ATAV-2 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 hull. This projectile engages the threat 50 meters away from the vehicle by detonating on it. The system is reloadable and storage in the AFV allows for 20 extra projectiles to be carried.

Screening and Decoys: The ATAV-2 carries 2 6 tube 80mm. grenade launchers on the front of the hull. These tubes can fire IR Screening and IR Decoy grenades to help the AFV screen or avoid incoming threats. In addition the vehicle is equipped with a standard self screening using condensed diesel fumes.

Fire suppression: ATAV-2 uses several systems to prevent and suppress fires. The crew compartment has 5 BCF canisters and 5 optical/thermal fire detectors. The canisters are operated either automatically by the detectors or manually by the crew. 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 5 tanks in the front and back of the AFV, with cutoff valves allowing the use of each tank separately.

Explosion prevention: The missile reloading system is especially protected and has Blowout panels to direct explosion energy away from the crew. The crew seats are all of the suspended type, keeping them above the floor in case of an explosion underneath the vehicle.

NBC protection: The ATAV-2 is equipped with an overpressure system. The system pumps air from outside the vehicle through a system of filters and into to the crew compartment, creating an overpressure that keeps contaminated air out if the tank is fully buttoned. If the tank cannot be fully buttoned, each crew member 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.
The ATAV-2 has towing shackles on its front, back and sides, to enable recovery in hard situations.

Communications and interface:

Internal communications: The ATAV-2 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 ATAV-2 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 TM-2 is equipped with a AFV/infantry telephone located at the rear of the vehicle and connected to the commander’s internal communications.

Battlefield Management and Navigation: The ATAV-2 is equipped with the BASTION (http://forums.jolt.co.uk/showpost.php?p=14715018&postcount=381) system.

Interface: The crew interface of the ATAV-2 includes a LCD screen/Control for each crew member, clearly showing the information that crew member needs. The LCD screen/Control is encased in high-resistance polymer and has buttons allowing control of many systems in the tank. These electronic controls are all backed-up by conventional switches and controls in case they malfunction.

Amenities:

The ATAV-2 gives its crew all that’s needed to fight and stay buttoned for long periods. A 50 liter internal, NBC protected water tank supplies hot and cold water through a water point. An air-conditioning system connects to the crews overalls to keep them cool while fighting or warm while waiting. The ATAV-2 can hold 7 days worth of rations for its crew. An electric cooking pan, along with plates and utensils are stored in special compartment.

Section 2: The missile system- TLFFR 150

The Tube Launched Fire and Forget or RADAR-150 “Assassin” is based on the “Hunter” GLATGM, but has many modifications. The Fire and Forget system, IIR seeker, and RADAR jammer are identical to the ones used on the “Hunter”. The RADAR system was developed for the “Assassin”, as was the radio command system.

Specifications:
Total weight: 46kg (with tube)
Warhead: Tandem HEAT, 8kg
Range: 10.000 Meters.
Speed: 400 Meters per second
Time to maximum range: 25 seconds
Guidance: Electro-Optic/IIR seeker fire and forget, RADAR, Combined
Attack modes: Top Attack, Direct Attack
Penetration: 1000mm RHA after reactive armor
Cost per unit: DPRs given with purchase of ATAV-2, for use only on ATAV-2

In general the “Assassin” system has 6 sub systems:

1)A retractable, 2 rail launching system for TLFFR-150 “Assassin” ATGM. The launcher is housed in the center of the vehicle, and deployed before firing. Inside the vehicle is a loading system holding 16 more tubes, in two 8 tube carousels. After the two missiles are fire from the tubes on the launcher, the tubes are jettisoned. The launcher arm than lowers in to the hull and two new tubes are loaded. The rate of fire is up to 12 missiles per minute.

2)A day and night optical sight, located at the front of the vehicle. This system is based on sights used in other NPS AFV designs, mainly that of the TM-2. The system combines a electro-optic sight with a Thermal Imaging System for night operations. Both in day and night modes, the system has magnification x10 in narrow field of view and x3 in a wide field of view. This sight is used for observation and for firing missiles in Fire and Forget mode.

3)Wave millimeter RADAR which is located near the optical sight. It has a theoretical range of 10,000 meters and allows accurate identification of targets at 8000 meters. The RADAR is used to direct the missile in the radio command mode.

4)A fire control system. This system collects data from the sight and the RADAR, displays it on the controls of both the weapons operators, and processes the commands from the controls to send them to the missile over a radio transmitter.

5)Radio transmitter with a range of 10,000 meters used to guide the missile in radio control mode.

6)The TLFFR-150 missile itself- see more information below.

The TLFFR-150 missile is made of these main components:

1)Flight rocket engine- A solid rocket engine which is used to propel the missile out of the tube and to its target

2)A primary HEAT charge, which is used to penetrate the target.

3)A precursor HEAT charge, used to trigger NERA or ERA plates on the target and clear the way for the main charge.

4)RADAR Jammer- A combined Barrage Jamming and Digital Radio Frequency Memory jammer installed on the front of the missile.

5)A radio receiver used to receive guidance from the fire control system.

6)Imaging Infra Red Seeker: Used to detect emissions from the target and provide information for guidance. The IIR is cooled by compressed gas.

7)Electronics Package: This includes the processing units that receive target data from the fire control, process data from the IR seeker, and control the flight of the missile.

8)Batteries: Two batteries power the electronics, seeker and servos.

9)Servos and fins: 4 fins are located at the back of the missile each controlled by a servo.

RADAR jammer:

The Jammer combines two jamming methods, the first is barrage jamming. The jammer powers up 150 meters above the target and jams in all known frequencies used by APS systems. The second is Digital Radio Frequency Memory. When a receiver on the jammer receives the first signal from the APS radar it stops jamming in all frequencies and instead sends a false return to the APS, showing multiple targets at different locations. This causes the APS to expend ammunition while still not intercepting the missile.

Operation:

The “Assassin” has 5 modes of operation. These modes are: Fire and Forget, Radio Command, Simultaneous Launch, TMOT, and Anti Helicopter

Fire and Forget- The missile is aimed by the thermal imaging system prior to launch. The fire control system transmits target data to the missile through a physical connection on the launcher. The missiles are launched and the IIR seeker identifies the target. The missile than guides itself to the target and attacks it in a top-attack path. This is the standard launch mode.

Radio Command- The missile is aimed by the RADAR. The operator locks the RADAR on target and the RADAR than guides the launched missile to its target via a radio link. The missile attacks the mode in a top-attack approach. This mode is used to engage targets at longer ranges, targets using thermal decoys, or targets using thermal reducing materials.

Simultaneous Launch- This mode is meant to allow two missiles to be fired at the exact same time. One weapons operator uses the Radio Command mode while the other uses the other uses the Fire and Forget mode. Each aims at a different target. This allows firing both missiles at the exact time. This mode is very useful in ambushing armor, as it allows destroying many tanks in the first moment of engagement.

Anti Helicopter- The anti helicopter mode is essentially similar to the simultaneous launch mode. The difference is that in this mode one weapons operator uses both systems to engage a single target. This means that two missiles are launched at the same time at the helicopter using two different guidance systems. The missiles engage the helicopter in a direct attack approach. This mode increases the chances of hit against a helicopter considerably.

TMOT- Two Missiles One Target. This mode is used against targets with very advanced countermeasures and active protection systems. It is similar to the anti helicopter mode but the missiles engage the target in the normal top attack approach.
