HTD-165/HAT-165 “Colossus”

Image:http://i660.photobucket.com/albums/uu322/NWIpics_2009/165.png


Background:
The HTD-165 and HAT-165 were born out of the same specification made by the Nachmere Parliamentary Guard for its Heavy Armored Assault Division. The specification called for a Tank that can engage and destroy any existing MBT while outranging the guns carried by any current MBT. It also asked for the vehicle to be able to attack and destroy fortifications, fight massed infantry at close ranges, and lead heavy armored formations in breakthrough battles.

Realizing that the design will in fact not be a MBT but a heavier, purpose built vehicle, NPS set to work on a new design, using MBT-140 technology but not limiting itself to it. Soon it became obvious that the specification calls for two different vehicles. One must have a long gun for armored duels at long distances. The other must have a shorter gun with as little “dead-zones” as possible, a supplementary weapon to fight massed infantry, and probably a dozer blade.

NPS indeed developed two vehicles. The first is the Heavy Tank Destroyer 165(HTD-165) with a 165mm 50 calibers (8.25 meters) ETC gun. The second was the Heavy Assault Tank 165(HAT-165) with a 165mm 35 calibers (5.77 meters) ETC gun. Both AFVs carry the same secondary weapons, with the HAT-165 also carrying a flamethrower. The vehicles share most parts and features, including power units. The HAT has slightly better protection while maintaining similar weight to the HTD, thanks to weight reductions resulting from the shorter lighter gun.

Both systems offer unmatched protection and fire power for heavy armored formations. They can be used to fearsome effect in both breakthrough battles and dynamic defense operations.

Fire Power:

The “Colossus” carries a 165mm L/50 or L/35(HAT-165) Electro- thermal Chemical (ETC) smooth bore gun, A 20mm automatic cannon, a 7.62mm machinegun, a 12.7 commander’s machine-gun, and 2 8-tube multi-purpose grenade launchers. The HAT-165 version also has a forward mounted flamethrower.
A) The two variants of the “Colossus” differ in their main gun. In both variants the gun is loaded by an automatic loading system capable of loading up to 10 rounds per minute. The human loader is tasked with solving any problems in the system.
The HTD has a L50 gun capable of penetrating any armored vehicle at very long ranges (up to 2500 meters for even the hardest opponents). This gives it an edge as the frontal armor of the HDT itself is capable of defeating even 140mm rounds at these ranges. The HAT on the other hand has a L35 gun. While being drastically less powerful than the L65 in armor penetration, this gun has many advantages for the role of the HAT. It is shorter and lighter, thus needing less of a counterweight and allowing for more protection at the same weight. It also has less muzzle energy so the recoil system is smaller and this allowed for storing more ammunition in the turret saving room in the hull for the flamethrower and its fuel. In addition the L35s shorter barrel allows for more elevation and depression. It also enables the HAT to rotate its turret in close quarters where the HTD cannot.
Both guns can fire all of the standard ammunition types, although for the L35 does not fire APFSDS but uses the “Gladiator 165” GLATGM or a tandem HEAT round for anti-tank operations.

B) A 7.62mm coaxial machinegun is located coaxial to the right of the main gun. The 7.62 is able to provide large amounts of fire power with good lethality against exposed infantry and soft vehicles. The 7.62mm was retained due to the small space it requires and to save 20mm and main gun ammunition.

C) A 20mm coaxial automatic cannon is installed left to the main gun. The autocannon is capable of firing 300 rounds per minute, and is suitable to use against light armored vehicles and infantry.

D) The 12.7mm is used as a commander’s weapon, for use against close and medium range infantry. The 12.7mm can be fired in single round or full automatic and is deadly accurate against infantry at up to 1200 meters. In the “Colossus”, the 12.7mm is mounted in a fully stabilized weapon station, which can be operated from within the tank while it is “buttoned”. The 12.7mm weapon station has a compartment for a 200 rounds belt.

E) The multi-purpose, close range, 2X10 tube 80mm grenade launching system is into the armor plates in the front of the turret and fired from a panel in the commander’s controls, the grenade launchers are used to engage infantry at short ranges, up to 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.

F) On the HAT-165 a fixed, forward facing flamethrower is locates in the center front of the hull. The nozzle can only be elevated or depressed. The Dozer blade has an opening for the flame to pass through. The flamethrower has a separate tank for its fuel and is fired by the driver. It is meant to be used against entrenched infantry at ranges of up to 100 meters.


Fire Control and Observation:

The “Colossus” uses the same FCS and observation as the MBT-140A1, adjusted for the different weapons.
A two-axis Gunner's Primary Sight- Line of Sight (GPS-LOS) increases the first round hit probability by providing faster target acquisition and improved gun aiming. 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's sight together with the range measurement from a laser rangefinder. The sight allows for the gun to be stabilized on a specific moving target (“Pixel Lock”).The Eye-safe Laser Rangefinder (ELRF) has range accuracy to within 10m and target discrimination of 20m. The gunner also has an auxiliary sight with magnification x8 and field of view 8°. The FCS elements needed to fire GLATGMs are incorporated. ATGMs can be fired by the main gun and controlled from the gunner or commanders interfaces. The very high position of the commander’s sights means that the tank can fire the ATGM without a LOS from the gun to the target.

The CITV (Commander’s Independent Thermal Viewer) is integrated with a weapon station holding the 12.7mm machine-gun. As a result the CITV has two modes of operation. In the first mode the CITV acts as a separate, fully stabilized day and night sight for the main and coaxial weapons, allowing the commander to “slave” the gunner controls to identify targets or fire. In this mode the CITV allows the commander to identify, select, and range targets before even the top of the turret is exposed, and while remaining buttoned. In the second mode the CITV acts as a fully stabilized day and night sight for the 12.7mm weapon station. In both modes the CIV allows for all the features of the FCS.

The fire control computer automatically calculates the fire solution based on: lead angle measurement; bend of the gun measured by the muzzle reference system; 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. A secondary emergency system enables for firing using a mechanical ballistic computer.

The driver has either three observation periscopes or two periscopes on both sides and a Driver’s Thermal Viewer (as standard). The periscopes provide 120°field of view. The driver also has rear facing TI camera to enable driving forward with higher accuracy, night and day.

The loader has an independent rotating day and night (Light Intensification) viewing system, useful in urban situation to maximize the tanks observation capabilities.

Protection and Survivability:

The “Colossus” is protected by a combination of composite passive armor, Non Explosive Reactive Armor, and an Active Protection system.
Armor: The armor is a composite made of layers of steel, DU (Depleted Uranium), and ceramics. The crew compartments in the MBT-140 are lined with Kevlar to prevent spalling. The passive armor is angled and in some parts spaced, to protect against virtually any large caliber KE threat at less than typical contact ranges.

Reactive Armor: The “Colossus” has spaced, multi-layered NERA (Non Explosive Reactive Armor) plates on most of its turret and hull. The NERA plates protect the tank against medium CE threats, and when combined with the passive armor suite also minimize the penetration chance of even the largest CE threats.
Active Protection: The HAT/HDT-165 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 turret, 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 turret. This projectile engages the threat 50 meters away from the vehicle by detonating on it. The system is reloadable and storage in the tank allows for 20 extra projectiles to be carried.
Screening and Decoys: As mentioned before the “Colossus” carries 2X10 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 “Colossus” is equipped with a standard self screening using condensed diesel fumes.
Fire suppression: “Colossus” uses several systems to prevent and suppress fires. The turret and driver compartment are both equipped with fire detectors and 5 BCF canisters. The canisters are operated either automatically by the detectors or manually by the crew (Gunner and Commander 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 6 tanks in the front and back of the tank, with cutoff valves allowing the use of each tank separately.

Explosion prevention: All main gun and Grenade ammunition is stored in separate containers, made from high-resistance anti-flame material. Blowout panels are located above the 165mm ammo storage 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 tank.
NBC protection: The vehicle is equipped with an overpressure system. The system pumps air from outside the vehicle through a system of filters and into to the tank, 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 “Colossus” has towing shackles on its front, back and sides, to enable recovery in hard situations.

Mobility:

The “Colossus” is powered by a multi-fuel 2300hp, twin turbo-charged 2500hp (2000kw) engine. The engine is located at the front of the tank, to the right of the driver compartment. A hydro-mechanical semi-automatic transmission transfers power from the engine to the final drives. The transmission has 5 forward gears and two reverse gears.
The “Colossus” has 8 pairs of road-wheels with separate helical-springs and pneumatic dampers. The helical springs were chosen for better performance over harsh terrain. The tracks are 800mm wide, and do not have rubber soles. Connection between sections is made by a separate pin.
Vertical obstacle ability is 1.5 meters, with trench crossing being 3.6 meters.

Auxiliary Power Unit:
The “Colossus” has a small auxiliary power unit that can provide power to all systems while the tank is stationary. The advantages of this setup are a reduced thermal signature when static, reduced noise levels, and reduced fuel usage.

Dozer Blade:
The HAT-165 has a hydraulic dozer blade attached to its front to clear or destroy obstacles and buildings. The blade is made of Steel and will survive small explosions (up to 20 kg HE). It also adds extra protection to the front of the tank.

Gladiator 165 Gun Launched Anti-Tank Missile:
The Gladiator GLATGM is fired from the main gun like any other 165mm ammunition. The Gladiator locks on to its target by its IR image and vector, and requires no further aiming after the launch(fire and forget). While its penetration figures are not sufficient to penetrate the frontal armor of MBTs, it is a Top-Attack missile, and will easily penetrate the top of any MBT. Gladiator also has a direct attack anti-helicopter mode.

There are too many superlatives here. Despite that, however, I'd back a Sumerian TD-7 or Lyran LY6A1 over this, any day of the week. They're kinda the pick of the crop for the very heavy AFVs, though.

Having said that, though, the design itself isn't half bad...

OOC : But did anyone ask for your opinion here?

And be careful about making unfounded accusations over TG.
