Stadtholder MBT

The Stadtholder Tank ("Stadhouder Tank") is a Main Battle Tank that is produced by a Joint Venture of Nimrod BV and the Knootian Automotive Industry Cooperative. It was designed to operate with equal effectiveness in low intensity and high intensity conflicts, with a particular focus on urban operations. It can support infantry in assaulting hard points and destroy other tanks.

Design History
The earliest tanks with the Stadtholder name came into service in 1987. Initially these were little more than inferior re-engineered versions of the Leopard 2 series of tanks, whose production in the then-Knootian Republic had more to do with generating employment in marginal constituencies than any sound consideration of tactics or strategy. Weighing in at about 70 tons and firing a 223 mm shell that was (and remains) incompatible with the arms stocks of allied nations, the first two incarnations of the Stadtholder were rapidly consigned to obsolescence.

Development of the Stadtholder III began late during the Vogels administration (1993-1997), and it continues to be used, mainly by the Colombian National Army and the apartheid regime in South Epheron. In a nod to the standardisation that was then promoted by the South Atlantic Treaty Organisation (SATO), it features a standard 120mm gun design and can fire the widely used the .50 BMG rounds from its two heavy machine guns, one of which can be remote controlled from the commander's station. The new design also replaced a human loader with an auto-loading system. The main improvement was the introduction of proprietary advanced materials, most particularly the spaced, multi-layered composite armour that makes the third incarnation of the Stadtholder both relatively lightweight and able to take a punch.

In 2004, the nos Círdan administration proceeded with plans to develop an upgrade to the Stadtholder III that would feature a 140 mm cannon, as a counter to the rapidly expanding size and armour of Main Battle Tanks, in particular the emergence of Heavy Main Battle Tanks or 'Supertanks', in particular amongst more militaristic nations that presented a potential threat. To cope with the extra weight of the main gun, counterweights were added to the turret rear, and the number of available rounds had to be significantly reduced to deal with the increased size of the larger projectiles. This, and the mixed results of early trials, raised significant doubts about the ability of new gun of the 'Stadtholder III-U ' to compete on a 21st century battlefield. The Ministry of Foreign Affairs and Defence began to seriously look into the possibility of scrapping the project and instead purchasing a small number of foreign Heavy Main Battle Tanks to be fielded alongside its existing complement.

The project was saved when a corporate Joint Venture with Nimrod BV (based in Armeloo) introduced the concept of a domestically produced Main Battle Tank that was capable of launching anti-tank guided missiles (ATGM) from its gun. The Pijl [Arrow] Gun-Launched ATGM proved able to engage targets to beyond line of sight, up to a range of 15 kilometres. By mixing shells and missiles the Stadtholder would be capable of carrying out a broader range of tasks. Apart from the main high-explosive anti-tank (HEAT) warhead, versions of the Pijl carrying HE-F, Thermobaric and cluster munitions were developed over time. The newly dubbed Stadtholder IV also saw many improvements in battlefield awareness that were subsequently backfitted onto the Stadtholder III, as well as the introduction of an NBC air filtration system to replace the old method of overpressurisation to protect the crew from Nuclear, Biological and Chemical (NBC) threats, which was not backfitted.

The Stadtholders met their trial by fire during extensive high-intensity combat in the Iesus Christi Civil War. The 4th Armoured Division of the Ale-Yarok Defence Force (AYDF), Knootoss' 13th Army and the CNA's 1st Mechanised Infantry Division supported the allied combined arms offensive against the Iesian loyalists. While losses among tank crews were comparatively high, the Stadtholders did manage to effectively take out more enemy tanks first, though this can also be ascribed to the loyalists' tendency to mount frontal assaults even when they did not have numeric superiority.

The brand continues to be developed to suit its prospective users' needs. The Ale-Yarok Defence Force favours the Stadtholder VI-B, which is faster and lighter lighter due to the removal of some excess armour and the introduction of a more powerful engine. It is fine-tuned for operating in desert environments. Nimrod BV and the Knootian Automotive Industry Cooperative continue to hope that their product will find greater appeal among foreign clients.

Armament
All current incarnations of the Stadtholder use auto-loading, fully stabilized, smoothbore guns as their primary armament, allowing the gunner to engage hostile targets at speed. Its high explosive shells can be programmed to airburst over the target. If an unprogrammed round is fired, it will detonate on impact. From the Stadtholder IV onwards, these shells may be exchanged for Peil missiles of the HEAT, HE-F, Thermobaric or Cluster variety. Rumours that chemical weapons cannisters were adapted for use in the 120mm gun of the Stadtholder III have not been publicly confirmed. All variants come equipped with digital fire control systems with laser rangefinders and advanced night vision and sighting equipment, allowing the tank to function by day and by night.

Additional firepower is provided by two secondary weapons: a 12.7×99mm heavy machine gun that can be remotely controlled from the commanders' station sits atop the turret and can be used against enemy infantry, vehicles, buildings, low-flying aircraft and light fortifications, carrying 200 rounds that are ready to fire and storing 400 more. This heavy machine gun has an effective firing range of 1,800 m (2,000 yd) and a maximum firing range of 6,800 m (7,400 yd). A coaxial 7.62mm medium machine gun has 1500 rounds ready to fire rapidly against infantry and other vulnerable targets, storing 8000 more.

Battlefield awareness
In line with Knootian military thinking, the Stadtholder III, Stadtholder IV and Stadtholder VI-B have been fitted with an extensive range of military sensors. They use infrared, low-light, and remote-camera imaging, as well as a Spiegel ('Mirror') class ground RADAR, which is capable of spotting advancing enemies up to 35 kilometres away. A Battlefield Management and Navigation computer is installed, allowing interface with the national CAESAR Battlefield Management System. Hidden digital camera's have been dispersed throughout the hull, allowing the commander to 'see through' the hull using the HUD that is typically issued to Knootian Landmacht officers.

Armour
For protection the current generation of Stadtholders rely on a proprietary composite armour, the exact composition of which remains classified. The material appears to be lighter than that of Main Battle Tanks of similar dimensions, but this does not seem to have hurt its ability to absorb incoming damage. Like its predecessors, the current line of Stadtholder tanks use integral spaced armour as protection against high-explosive anti-tank (HEAT) warheads, containing a slanted first armour stage (disturber), a specially hardened second stage (disrupter) and a softer third stage with high ductility (absorber). The disturber is to ideally deflect or at least manipulate the direction of incoming kinetic energy penetrators, which are then shattered and fragmented when hitting the disrupter. The absorber stage finally erodes and contains spalls and fragments. The sloped front of the tank, meanwhile, increases its protection from incoming projectiles by increasing the thickness measured on a horizontal plane.

As the Stadtholder III and Stadtholder IV are expected to support infantry in assaulting hard points in urban areas, they have received upgraded 360° protection against RPGs and mines. Additional heavy armour has been added to the turret front, and on the hull and side skirts to increase its survivability. The Stadtholder VI-B has sacrificed this additional plating in favour of speed and performance. The Iesus Christi Civil War saw the introduction of front- and rear-facing modular armour plating (appliqué armour) that can be mounted onto the hull externally. While not standard, such additional plating has been produced in numbers and is thought to be a viable option during certain threat scenarios.

Iron Tide and Electronic Countermeasures
Finally, they are equipped with Iron Tide APS, a piece of technology that was originally developed by the AFV division of Schwerpunkt in Nachmere. This modular soft and hard kill system has been reconfigured to operate with the CAESAR battle management system and take full advantage of the systems of each specific vehicle it is mounted on. Infrared sensors located on sensor mast, a laser warning system and the Spiegel ground RADAR system are used to identify incoming threats in a 360 degrees arc around the protected vehicle. A speed compact processing unit is then used to allow the tracking, classification and engagement of threats. The software can use the data from the radar to identify threats and choose which threats to engage and which threats not to engage. It also chooses what counter measure to use against a threat. The processing unit is linked to the CAESAR system, allowing one unit to network with others.

2 twin-barreled automatically reloading, fully stabilized, rotating launchers fire combustible, fin-stabilized 80mm projectiles that explode at less than 1 meter from the threat, causing it to destabilize and either fall apart in the air or go off target. This method is effective against both CE threats and KE threats. 12 projectiles are carried in the auto-reload magazines of the system. In the Stadtholder tanks it is moreover connected to the turret traverse system, rendering it able to traverse the turret to fire smoke grenades if needed (requiring only a confirmation from the commander).

Active Electronic Countermeasures that are designed to passively defeat enemy anti-tank missiles by jamming their target designation and guidance systems to provide another layer of defence against incoming attacks. The system includes both a radio frequency jammer and a laser/infrared jammer. The R/F jammer is a high output unit which is programmed to work on frequencies used by radio guided munitions. As the missile nears the protected vehicle, the jammer outpowers the guidance signal, severing the tie between the missile and its launcher. The laser/infrared jammer works either by directing false guidance data at the incoming threat or by blinding it completely. The jammers are located in the sensor mast of the system.

Mobility
The Stadtholders engines have been designed by Peacock Motors and are produced in Pantocratoria. The current line of Stadtholder tanks rely on a liquid cooled turbocharged V12 diesel engine to provide 1,500 PS (1,103 kW) of engine output, giving them a power-to-weight ratio of 21 or higher. The transmission provides seven forward gears and one reverse gear. The Stadtholder VI-B uses a more powerful engine to increase its maximum speed and performance further, making it faster than most of its rivals, even if it sacrifices some of its endurance in the process as fuel consumption is increased.

The tanks can wade through water that is up to 1 meter (3 feet and 3 inches) deep, allowing them to ford shallow rivers and streams. They can theoretically be airlifted by heavy-lift transport helicopters, but doing so puts the helicopter in a very perilous position, and it has only been done in safe zones for purposes of strategic mobility.
