M15 Lionhound II Main Battle Tank (http://img30.exs.cx/my.php?loc=img30&image=m154cg.png)

The KAF90F was a great member of the imposing and revolutionary KAF90 family, but with newer armored vehicles it began to show it's age. With a massive upgrade to the design, the Lionhound has been replaced with the Lionhound II.

Propulsion

The vehicle is powered by a hybrid-hydrogen engine. It can propel the vehicle up to 50mph on optimal surfacing. The suspension has been designed to carry the 75 tons well and allows for excellent climbing and turning ability. The system is designed to vent as much air as possible downward to reduce heat plume.

Armor
The MAgneto Hydrodynamic Explosive Munition (MAHEM) program will demonstrate compressed magnetic flux generator (CMFG)-driven magnetohydrodynamically formed metal jets and self forging penetrators with significantly improved performance over explosively formed jets and fragments. Explosively formed jets (EFJ) and self forging penetrators (SFP) are used for precision strike against targets such as armored vehicles and reinforced structures. Current technology uses chemical explosive energy to form the jets and fragments. This is highly inefficient and requires precise machining of the metal liners from which the fragments and jets are formed. Generating multiple jets or fragments from a single explosive is difficult, and the timing of the multiple jets or fragments cannot be controlled. MAHEM offers the potential for higher efficiency, greater control, the ability to generate and accurately time multiple jets and fragments from a single charge, and the potential for aimable, multiple warheads with a much higher EFJ velocity, hence increased lethality and kill precision, than conventional EFJ/SFP.

Armor from outside in:
Mayhem Reactive Armour, Smart Armour, EleRA, Momentum Transfer Armor, NxRA, CERMAT, then Chobham with Tungsten Honey Combs, then another layer of CERMAT, and finally Rubber insulation to prevent spalling.

Defensive Systems

TAMS II or Tank Anti Missile System. This is a 7.62mm Caseless weapon. A 40mm shortbarrel grenade launcher, tied into the LIDAR and MM wave targeting nad fire control systems for engaging ATGMs. Also mounted is WASP II for dealing with weapons targeted at the side of the vehicle. The Wasp AMPS consists of packets of 5mm Flechettes. Each packet contains flechette "Needles" and their propellant. When the computer in the Wasp AMPS detects incoming missiles, by the same criteria ARENA does, it fires off sections of the appropriate packet at it, showering the missile with high velocity (1500mps) armor piercing flechettes, destroying it, which will eliminate the missile completely, or detonating it prematurely, with minimal, if any damage to the vehicle. In extreme situations, the Wasp AMPS can be used against infantry, which causes horrific effects. Two laser blinders are mounted on the tank for dealing with enemy optics or IR seekers.

Armarment

The Lionhound II mounts a 150mm main gun, using ETC propellant. This huge weapon requires an extensive recoil buffering system to keep the tank on balance. The weapon is guided via the LIDAR Rangefinder/Tracking system, along with Thermal, Enhanced Optic, and SLICS uplink. The vehicle also mounts an autoloader that works faster than a human, though due to the stress on it a loader/commander sits in the turret.

The coaxial is a 40mm automatic cannon capable of firing at 700 RPM. Its main purpose is taking out light-mid armored targets and can use the same fire control as the main gun.

In the miniturret sits the TAMSII, the 40mm, and a 15.5mm FN BRG Heavy Machine Gun. The miniturret is controlled by the loader commander, along with any of the ATGM pods attached to the tank.

Can I ask why you use a 7.62mm caseless weapon as a "Tank Anti Missile System"

[Well, considering this can't possibly be modern tech even by the loosest modern tech definition in NS. I also don't think you're taking into account the speed at which ETC projectiles are launched.

I believe the average ETC SABOT travels at around 2.2 km/s, given an average engagement range of 4 kilometers you have approximately 1.8 seconds to react to any enemy firing at you. Now, I don't know how much power you think you have in that tank, but I can guarantee you that to be able to have a computer that could calculate an intercept vector that fast and then feed it to the defensive systems and for the defensive systems themselves (especially MAHEM) to react with what time was left would require power in the high kilowatts or low megawatts. Expending that much energy at once is enough to seriously shorten the life of all but the largest nuclear reactors.

In short, unless you have a portable fusion reactor in that thing, it ain't happening.]

OOC:

SS, yeah, the armor is a sticking point. Artitsa said we should go through with it, so I kept his armor writeup, but for now I'm treating them as anti HEAT and not anti sabot.

Witzgall, look up the 'Tank Anti Missile System'. TAMS II also includes a frag grenade launcher and the WASP pods, along with any attached SLID units.

OOC: Obviously not modern tech, so not going to worry about it.
