The FA.90 Leopard (Glasic: Feithicil Armúrtha 90 Liopard) is a main battle tank (MBT) designed and manufactured by Byrne Heavy Industries (BHI) as a replacement for the FA.79 Leon and FA.83 Tíogar. It entered service with the Glasic Army in 1990. It itself has recently begun to be supplemented with the FA.15 Pantar.

Development

By the 1970s it had become apparent that the the FA.61 would not be sufficient in the face of newer armour being developed in Casaterra and Hemithea. Up until this point the FA.61 could be relied on to deal with most threats and indeed had been upgraded to remain competitive. After a lengthy and troubled development the FA.74 would not see service service instead being succeeded by a modified Type 74 from Dayashina, this entered service as the Leon. The FA.79 was primarily intended as a stop-gap before a clean-sheet design could enter service. This took much longer than initially anticipated and resulted in further stopgap tank being procured, the FA.83 which essentially the FA.79 witted with Burlington appliqué armour and improved gun.

With the adoption of the Tíogar the Glasic defence procurement agency was still looking toward the future with an eye on replacing the at the very least the FA.79 with an entirely clean sheet design, as a result multiple mockups and prototypes for replacement vehicles were produced between 1978 and 1983. A clutch of Leopard 2s from, Eisenmart were procured for testing and the loan of one of the STC prototypes (which would become the Type 90) to better develop a Glasic design. As a result of this some of the prototypes were based on the FA.79/83 whilst others were built from scratch to test new technologies.

Most major contract work for these studies was undertaken by a consortium of Timoney Automotive, Timoney Technology and Brennan Brown alongside the Defence Research and Technology Exploitation Institute (RTEI). After the desired vehicle layout was established a further series of prototypes were constructed in mild steel, all completed between 1985 and 1986. A second series of prototypes were constructed in 1987 incorporating improvements for issues identified during early troop trials. These were the first in the series to be equipped with a 120mm gun, the early prototypes being fitted with the 105mm L62 of the preceding FA.79. This new gun which was derived from an Eisenmatian weapon provided significant growth potential over the 105mm gun. The second and third series of trials between 1987 and 1988 further refined the vehicle's design, it eventually being frozen in 1989. Low rate initial production beginning in late 1989. A second round of troop trials prior to mass-production rectified several small issues which manifested during the trials. Mass production commenced in 1990 and continues to the present day.

Design

The design of the Liopard superficially resembles that of the Eisenmatian Leopard 2 or Type 90 with its angular turret and general shape but the similarities end there. The Liopard has a highly sloped front hull, greatly increasing the relative thickness of the vehicle's armour without the substantial increase in weight otherwise dictated by the required levels of protection. The driver, partly as a result of the highly sloped frontal armour is seated in a supine position between three self-sealing fuel tanks (front and side) which, serve the additional role of adding further armour protection through both their construction method and contents. Additionally, an in-built armour package ahead of the driver further increases the frontal resistance of the vehicle. The sides of the lower hull were originally of constant thickness but production models began to feature aplliqué plates welded to either side of the fighting compartment.The upper hull sides contain further armoured fuel cells as does the ammunition compartment for a total of 1,150 litres inclusive of the bow tanks.

The Liopard was initially to feature an MB 873 V12 engine manufactured in Tír Glas under licence by Timoney Automotive, whilst this was an acceptable arrangement at the time the Glasic army wished for a fully removable power-pack to improve accessibility and reduce maintenance time. This resulted in the introduction of a power-pack arranged around the smaller but more powerful MB 883. More recently the MB 883 have begun to be supplanted by the introduction of the MB 893, again smaller and more powerful than the previous design, this in turn has freed up valuable hull volume for other items such as fuel, improved air-conditioning and a auxiliary power unit.

The Liopard is steered by a pair of joysticks, one to either side of the driver, these are connected to electrically-actuated brake discs which are in turn connected to a 10 speed hydrostatic transmission. Between the driver's legs are the accelerator and brake pedals in their usual positions, again electrically actuated. The driver's seat can recline fully allowing for the driver to egress the vehicle through the turret in the event that their hatch is unusable.

The turret of the Liopard is of mixed construction with a cast front and welded mid and rear section, the front also having additional plates welded to it. The turret bustle is completely separated from the main turret structure by an armoured bulkhead and features blow-out panels in the roof to vent ammunition fires.

The Liopard utilises Horstman hydropneumatic suspension on all of its road wheels which allow for an adjustable ride height in addition to providing extra depression and elevation as well as smoothing out bumps and dips in terrain whilst on the move.

The main armament of the Liopard has changed both while in development and since its introduction. Initially the vehicle was schemed to use the tried and tested long-barrelled L62 105mm gun then in use by the FA.79 and FA.83, during development this was changed to a derivative of the Eisenmatian 120mm gun found on the Leopard 2. The change to a smooth bore gun necessitated the replacement of the HESH round with a HEAT round, again of Eisenmatian origin in the form of the DM12. Ordinarily the Liopard houses twenty-two ready-use rounds in its autoloader with up-to a further eighteen stowed in the hull as required. The gun is fully stabilised and computerised unlike the preceding FA.79/83 which greatly increases the first-round kill probability of the vehicle in combat, additionally the Liopard was the first Glasic vehicle to be equipped with a chain gun in a bid to reduce fume ingress into the fighting compartment. In its newer variants the Liopard has been fitted with a longer 55-calibre gun in place of the earlier 44-calibre weapon in a bid to improve armour penetration, though some vehicles have either retained or been retrofitted with 44-calibre weapons for operations in urban areas where the longer barrel of the 55-calibre weapon could pose problematic in regard to clearing obstacles. A 51-calibre 130mm gun has been trialled with vehicles so fitted receiving an extended rear bustle and modified gun cradle though it has yet to be decided whether the 130mm gun will be accepted for general use on the Liopard or whether the fleet will receive improved 120mm weapons, leaving the 130mm gun to a future vehicle.

The fire control system has changed greatly over successive variants of the Liopard, initially only able to be worked from the gunner's side of the vehicle but in subsequent variants both the commander and gunner are able to work the main and coaxial guns as required with the commander having the now commonplace override system. Recent variants of the Liopard have started to be fitted with the Elbit COAPS panoramic-sight for the commander and TIFCS for the gunner, replacing the Elbit SFIP system and Mitsubishi FCS. The new system allows for easier replacement and upgrading of sensors as well as integrating a laser range finder, allowing the commander to store firing solutions independently of the gunner.

Service History

The Liopard entered service as the FA.90 with the Glasic Army in late 1990 after final troop trials had been completed. They immediately equipped units of the Glasic Blackwater Army (GBA), tasked with defending Tír an Crainn from possible incursions by an ever more belligerent Vyzhvan regime or from Kolodoria. Like it's Casaterran stablemates the Liopard has found some export success, largely in Vinya as a standardised vehicle within the VDC. It has yet to be adopted outside of Vinya.

Perhaps unsurprisingly it was in Vinya that the Liopard's reputation would be forged, firstly during border skirmishes with Kolodoria and more recently in Operation Geas, the invasion of Vyzhva. Experience in the former greatly affected the roadmap for the vehicle's future. With a focus on urban combat coming to the fore rather than the originally envisaged en-masse engagements on the plains of Vyzhva and Tír Ealga it was decided to retrofit the independent tank regiments of the Glasic Army for urban operations with the remaining vehicles remaining focussed on the traditional anti-armour role.

Battle of Blackwater

On February 14th 2019, shortly after 00:00 local time the Queen's Dragoon Guards whilst crossing the river Blackwater into Vyzhva entered contact with what Initially thought to be a motor rifle regiment with armour support, later turning out to be a motor rifle brigade (believed to be from the 103rd Guards Armoured Division). During the ensuing battle the force of 56 Liopards supported by Ermin of the Royal Blacks fought doggedly to secure the Vyzhvan side of the Blackwater destroying 41 Vyzhvan tanks and numerous armoured fighting vehicles, damaging a further 11 without loss.

Battle for Targan

On March 3rd, 2019 a joint Glaso-Crainnic force began to assault the outskirts of the city state of Targan after a preliminary rocket artillery bombardment a four-prong attack commenced. The Glasic 1st Guards Armoured Division and Crainnic 6th Airborne Division lead the assault from the west whilst the Crainnic 3rd and 4th Infantry Divisions acted as a blocking force to the north and east of the city. Tanks from the Glasic guards units were involved in heavy street fighting with a number of vehicles being disabled by attacks from multi-story structures. Whilst losses in urban operations were to be expected, it had not been foreseen that Vyzhvan anti-tank teams in high-rise buildings would be as prevalent as they turned out to be.

Variants

FA.90A
The initial Liopard variant was unsurprisingly the A, manufactured between 1990 and 1992 these vehicles were quickly superseded in production by the B and even C variants resulting in the vast majority of A models being converted into driver-training vehicles as well as optionally manned mine-clearance vehicles.

FA.90B
The Liopard B had various internal changes such as the change to a removable power-pack as well as changes to the autoloader and forward fuel cells. Externally there is little to differentiate a Liopard B from a Liopard A. Like the Liopard A, many Liopard Bs have gone on to service in non-combat roles such as driver training vehicles.

FA.90C
The Liopard C designation was given to those Liopard Bs upgraded with thicker side and floor armour welded on as well as those vehicles built with it from new. The Liopard C was the first to feature a commander's override system, it also received a different arrangement of fuel cells to allow separate refuelling as well as to limit damage in the event of a hit. Other minor changes introduced with the Liopard C included a deflector plate for the turret ring and improved NBC system.

FA.90D
The most numerous Liopard production variant to date is the Liopard D which introduced substantial changes to the vehicle including the fitting of a fully digital fire-control system capable of handling newer ammunition types as well as a redesigned turret structure making extensive use of titanium and tungsten armour. The Liopard D can be split into two distinct tranches, those vehicles re-manufactured from Liopard Cs and those built as Liopard Ds from new. The Liopard D was the first to achieve export success and continues to be the minimum baseline for export vehicles.

FA.90E
The Liopard E is more than anything else an incrementally improved Liopard D which introduced the distinctive wedge-shaped "arrowhead" armour package reminiscent of the Leopard 2A5. The Liopard E also features substantially increased appliqué armour on the turret roof and upper and lower front hull as well as thicker side-skirts and improvements to the command and control and fire control systems. Other changes in the Liopard E include the installation of spall liners throughout the fighting compartment, the introduction of hull stowage for extra ammunition as-required and the replacement of the gun mantlet with an improved version. All Glasic vehicles have been brought up to at least E standard

FA.90F
The Liopard F is a further refinement of the Liopard E, introducing a more efficient and smaller power-pack the Liopard F also rearranged the turret interior, relocating the commander's sight to behind the commander's cupola. The Liopard F as a new production vehicle also introduced structural changes to the Liopard design including changes to the fighting compartment to make better use of space freed up by the new power-pack, the net result of these changes is a weight reduction of around
850kg.

FA.90G
The Liopard G is the current production standard for Glasic vehicles, the main changes from the Liopard F being the introduction of a 20kW APU, an improved intercom system, the ability to fire programmable munitions as well as the introduction of a GLATGM and both rocket-boosted and top-attack munitions, all stowed within the hull racks. The Liopard G also marked the first operational usage of so-called Smart-ERA for use against both tandem CE warheads and KE penetrators.

FA.90CG
The Liopard CG or Liopard Next-Generation is a technology demonstrator owned by the Glasic MoD to test industry-proposed improvements to the Liopard platform. The tank has received the name Failinis after the legendary hound, renowned for its invincibility on the battlefield and its ability to catch and slay any beast it encountered. Failinis introduced the majority of changes found on the Liopard F and G but has since evolved even further with the introduction of newly developed armour materials, fitting of a prototype 130mm gun, hybrid-electric transmission and regeneratively charged batteries for silent operation and movement. Additionally the vehicle has been provided all-round vision including "see-through-armour" systems for all three crew-members and micro-UAVs.
