Background:
Wishing to maintain the MBT140 as a legitimate and practical option for users facing top of the line MBTs, NPS started work on an upgrade as soon as the first MBT140s came off production lines.
The MBT140A1 is superior in several areas to the MBT140. It carries a more potent 50 calibers long main gun, better protection around the turret, and other improvements.

Note: The A1 is a direct development of the MBT140, you should read this:http://forums.jolt.co.uk/showthread.php?t=585063 before making a decision to purchase.

MBT140A1:
Place of Origin: Armed Republic of Nachmere and the Protected Dictatorship of Anghele
Designer: Nachmere Precision Systems | AFV Designs
Manufacturer: NPS Precision Systems Anghele Complex
Production Status: In Production
Crew: 4
Weight: 89 metric tons combat ready.
Length: 10.2 meters gun forward
Width: 4 meters
Height: 2.9 meters (without commander’s weapon station)
Armor: Composite, NERA
Primary armament: 140mm smooth-bore Electro-thermal Chemical gun
Coaxial armament: 2X7.62 Machineguns, 40mm Protecta AGL
Commander armament: 12.7mm Machinegun in a remotely operated weapons station
Close range armaments: 16 80mm grenade launchers
Ammunition storage: 40X140mm (Including “Gladiator” GLATGMs), 12000X7.6, 1000X12.7mm, 200X40mm, 48X80mm grenades
Engine: 2300hp (1700kw), Twin Turbo-Charged, Multi-Fuel.
Power to weight ratio: 25.8hp/ton
Suspension: Helical-Springs
Fuel Capacity: 2200 liters, +420 liters in jettison tanks.
Operational range: 490 kilometers with jettison tanks.
Speed: 72km/h on road, 52km/h off-road

Armament:
The A1 version has several differences from the original MBT140:
A) A new, 140mm ETC 50 calibers (700cm) long main gun, assuring penetration of targets at contact ranges.
B) The “Gladiator” GLATGM was developed for this gun. It is a 140mm, fire and forget, tandem ATGM with an 8 km range. Specifications for the “Gladiator” are attached at the end of this document.
C) A 40X53mm Protecta Automatic Grenade Launcher is mounted above the main gun and acts as a second coaxial weapon. This allows engagement of infantry and light AFVs at longer ranges and with higher lethality than the 2X7.62mm coaxial.
D) The 80mm close range grenade system is now incorporated into the armor plates in the front of the turret.

Fire Control and Observation:
The A1 has the following improvements compared to the original:
The FCS elements needed to fire GLATGMs are now incorporated. ATGMs can be fired by the main gun and controlled from the gunner or commanders interfaces. The very high position of the commanders sights means that the tank can fire the ATGM without a LOS from the gun to the target.
The driver now has rear facing TI camera to enable driving forward with higher accuracy, night and day.

Protection and survivability:
The turret armor on the MBT140A1 has been redesigned. Most of the added armor is spaced, but there is still around 4 tons of added passive and NERA. Specific attention has been placed on upgrading the turret-top armor.

Auxiliary Power Unit:
The MBT140A1 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.

Gladiator 140 Gun Launched Anti-Tank Missile:
The Gladiator GLATGM is fired from the main gun like any other 140mm 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.
Total weight: 48kg (with cartridge)
Warhead: Tandem HEAT, 8kg
Range: 10.000 Meters.
Speed: 340 Meters per second
Time to maximum range: 30 seconds
Guidance: Electro-Optic IR Homing, Fire and Forget, Top-Attack
Penetration: 1200mm RHA
Cost per unit: 30000 NS$

NOTES:
A)Upgrade costs for older MBT140s to MBT140A1 is 1.25 million NS$
B)The Gladiator GLATGM is also avilable for sale at M.A.C

OOC: 89 metric tonnes? Do you have a 2 foot thick chunk of un-perforated steel? Once again it'd be a total logistical nightmare, and with NERA and composite armor how would it even get the tank to 89 tonnes? Problems: speed is not likely to be 72 km/h. Having a person load the 140mm shell would be awfully difficult and thus would actually result in a lower rate of fire than an auto-loader. 140mm L/50 would be 7000mm not 700mm.

Recommendations: Use an autoloader, reduce the weight to under 75 tonnes, post designs at the NS Draftroom (http://z4.invisionfree.com/NSDraftroom/index.php?act=idx).

What do you mean? it is again, larger than any current tank, carries a bigger gun, and yes, has a lot of armor. 89 tons isent that much and there are plenty other afvs on NS to weigh that and more. get over it.

speed is not likely to be 72 km/h

Why It has a massive massive engine. The speed is more than possible with almost 26 hp/ton. The Leopard 2A5 for instance, with a hp/ton of just over 24, has a top speed of 72.

Use an autoloader,

It already has one pay attention.

post designs at the NS Draftroom

No, thanks. I only go to places where people are nice and talk to the point.

It already has one pay attention. No where in the write up does it say it has an autoloader and it has a crew of 4, which is rare for tanks with an autoloader...

...has a lot of armor What is your approximate armor thickness? Composites and NERA combinations are relatively light (as can be seen by the AMX-56 Leclerc and the XK2) and thickness isn't really the problem with "Chobham-esque" armor, it is positioning the armor so it will take a perpendicular hit and manufacturing out of superior material (silicon carbide instead of alumina).

No where in the write up does it say it has an autoloader and it has a crew of 4, which is rare for tanks with an autoloader (although your basis, the Merkava, is one such tank).


The Merkava IV does not have an autoloader.

I don't know why I have to keep repeating it.

ooc: well, having actually commanded a tank, i can tell you the 4th crewmen is more than just a loader. Either way, this is not a complete write-up, its just for the upgrade. here is the write up for the MBT140:

While you are correct about angles and materials, the claim that having more material(assuming its angled correctly) dose not give more protection is wierd.

AS far as my proposed RHA figures...Hmmm. Well, I would have to say that I was thinking in the realms of ~1700 vs KE 2100 vs CE. That doubles some protection estimates for modern MBTs. Lots of weight.

You are correct it dose not, it has a 10 round revolving magazine behind the loader.

First upgrade of 3300 units was purchased by The Wolf Hold.
