The AVS 54 (Informally known as the "Char Cavalier") is a 3rd generation main battle tank designed by AVS and manufactured by GIST Industries (Groupe Industriel des Systèmes au Terre) of Notreceau. The AVS 54 was designed to replace the ageing AVS 36 as the primary armored platform of the nation and currently serves as the primary tank of the Notreceauen Army. The informal name "Cavalier" is often used to refer to the tank, a reference to its superior speed and mobility when compared to contemporary MBT designs. The official designation "AVS 54" indicates the initial 54 ton weight of the Séries I variant.
History and Development
Following the entrance of Licana into the Omandan War and the successes of Operation Southern Cross the Department of Defense Research and Development (DDRD) determined that the AVS 36 MBT was reaching the end of its service life and had become ineffective at engaging Transnapistani armor. In response the DDRD (Department of Defense Research and Development) initiated the Programme Future Armor (Future Armor Program) in 1972. The DDRD, under direction from the Notreceauen Military Government in Exile, cooperated with the Lumeric Royal Defense Agency (ARDDR) and began collecting data on the Licanan [Insert] MBT. The DDRD selected AVS as the primary design company on the Notreceauen while the ARDDR selected Amante S.p.A as the primary design firm on the Lumenic side. The program ran until 1980 and resulted in a number of tank designs, as well as the Lumeric Mangusta Main Battle Tank.
AVS initially drew from previous design theories incorporated into the AVS 36 main battle tank and AVS 14 Light tank as well as Lumenic anti-armor philosophies which resulted in the AVS 43 in 1979. The AVS 43 was considerably cheaper than other contemporary MBTs and offered high mobility, however it's poor armor design and lack of reliable protection against cannon fire was a considerable concern. Initial testing of the prototype by the DRDD found that the tank would not offer a significant enough advantage over the currently in service AVS 36, citing its lack of protection and mechanical issues that had occurred in initial prototypes as the primary factors for cancellation. Likewise the failure of the Lumenic Mangusta tank to effectively combat Soviet Order armor showed the design philosophy behind the tank to be ineffective. The AVS 43 was the first Notreceauen MBT to field a 120mm smoothbore cannon however, a development that would be incorporated into the design of the AVS 54 along with the enhanced electronic suite that was featured in the vehicle.
Despite the failure of the AVS 43 and concerns about the ability of Notreceau to produce a tank capable of directly engaging Soviet Order armor, the DDRD decided to continue with the program even after Luminerra dropped out in 1980. In 1981 the DDRD issued an updated requirement for the new MBT, stating that it must maintain high mobility and passive protection while still providing double the RHA capability of current generation MBTs (400mm). In order to address these new requirements, AVS began development on an entirely new hull design in 1982, intending to keep weight as low as possible and to increase speed while incorporating experimental composite and spaced armor packages to increase protection. This was further accomplished by the introduction of a new engine which offered significantly more power compared to the engine in the AVS 43, and a proprietary suspension system which allowed greater weight displacement.
The first prototype was available in 1986 and featured a weight of 52 tons. Initial DDRD testing of the prototype found the speed and maneuverability of the tank to be exemplary while the protection met requirements sufficiently. Between 1986-1988 specialized equipment (smoke launchers, range finders, etc.) and minor armor modifications were introduced to the prototype culminating in the Séries I variant weighing in at 54 tons. The DDRD officially designated the tank AVS 54 in 1989 and production began in 1990.
The ten tanks Batch 1 of the Séries I were shipped in early 1991 and, after delivery testing were found to have manufacturing flaws in their engine housing and suspension units, never entering service. Batch 2, shipped in late 1991 and corrected many of the problems with the engine and suspension found in Batch 1, they were retired in 1999. Batch 3 was a further production run of the Batch 2 variation. Batch 4 was the first of the Séries II tanks and featured additional and modified armor packages as well as a fully corrected engine and suspension, following modernization programs in 1999 Batch 4 was cleared for continued service and remains as such. Batch 5-9 is a further continuation of Séries II construction, with batch 8 specifically introducing a better climate control system in the right rear of the turret.
Batch 10 is the first of the Séries III variants and shipped with a new armor packaged that removed steel from the composite and added tungsten and titanium to increase protection and offset weight. Séries III also shipped with an upgraded gunner sight and an enhanced thermal-optical camera for night operations and thermal targeting. Batch 11 integrated an IFF indicator for use in the new Notreceauen Lien de Bataille (Battle Link) battlefield control and integration system. Batch 12 was the first to integrate the Lien de Bataille command and control system in command tanks. Batches 13-18 were a further continuation of Batch 12 production.
Batch 19 was the first of Séries IV and was introduced in 2018. Séries IV features a drone launcher and control system in certain tanks for greater integration and expansion of Lien de Bataille capabilities. Séries IV also features further improvements to the composite armor makeup, the addition of a RWS and several other grenade and sensor launching stations. In November of 2018 the possibility of introducing an Active protection system on future Séries IV tanks began research and development. The intention is to deliver these systems onto future Séries IV batches beginning in 2020.
In January of 2019 a proposal to field a limited number of Séries IV tanks with the GIST-CN140-55/1 cannon was submitted to the DDRD for review.
Design and Variants
Protection
The initial Séries I and II featured a full welded steel chassis and turret with fitted modular armor designed to be replaced upon destruction, damage, or upgrade to future variants. Séries III introduced a new composite armor package specifically designed to defeat high-grade kinetic penetrators that utilizes a new mixture of tungsten and titanium and incorporates ERA blocking on the sides of the turret. Séries IV introduces a further refinement of the Séries III armor composite and allows for the application of further ERA blocking on the sides, front and rear of the tank (such as in the Balayeur configuration for urban warfare).
The AVS 54 is also equipped with the SPDRDM (Multi Discharge Tank Protection and Concealment System) launcher system which is mounted on the roof of the turret and forward and behind the turret ring. The SPDRDM fires a variety of infrared concealing rounds designed to defeat thermal imaging, conventional smoke grenades to provide concealment for the vehicle and in some configurations anti-personnel grenades to dispatch close proximity infantry and light skinned vehicle targets.
Imaging and Fire Control
The AVS 54 is equipped with the VA-20/20 optical gunnery sight. The sight offers magnification levels of 3.3x, 10x and 14x (Beginning with Séries III) for daytime channel settings. The thermal imaging sight for use with the nighttime channels offers magnifications of 3x, 8x, 10x, and 20x (Beginning with Séries III) and has some ability to defeat IR-chaff and obscuring measures. Despite initial concerns with the design, no auxiliary sight has been provided for use in the AVS 54, although as of 2010 provisions to include future AVS 54 variants with backup sights are being explored.
The AVS 54's commander has the ability to view the tanks surroundings via 7 periscopes and the COS-95 panoramic sight aperture. The COS-95 has 3x and 10x magnification at daytime channel settings and 3x magnification at nighttime channels settings. A further refinement of the COS-95, the COS-105 (Beginning with Séries III) features the integration of a laser range finder into the commander's sight and the introduction of automatic tracking technology allowing the commander's sight to track, record and feed data on a target to the gunner's sight increasing the hit probability and time to fire of the gunner.
The digital fire control system can be operated by either the commander or gunner independently and offers a real-time view of all the tank's systems and sensors providing full coverage of the tank and the gunner's sight. Command tanks in a platoon may also access the larger Lien de Bataille network for a full-spectrum view of the battlefield and the location of other elements. Beginning with Séries IV the digital fire control system also has the ability to record and receive input from tank-launch UAVs as part of the large Lien de Bataille network.
Propulsion
Weighing in at only 57 tons in its most modern configuration the AVS 54 is considerably lighter than most contemporary main battle tanks and features a power-plant that gives it an impressive weight-to-power ratio. The primary power-plant is the 8 cylinder SMVBL-1500/2 diesel engine produced by GIST Industries which provides a horsepower output of 1500. The AVS 54 also features a hyperbar systems which incorporates a GHL LK-905 auxiliary engine which serves as both a turbocharger and auxiliary power unit when the primary engine is inactive. The AVS 54 features a GIST Industries STBL 2000 automatic transmission, with five forward and two reverse gears.
The maximum road speed achievable by the AVS 54 is 80km/h on road and 52km/h cross country. The maximum range is 550km unaided and 650km with external fuel drums. Due to its high weight-to-power ratio the AVS 54 is one of the fastest MBTs in service and features an impressive acceleration rate of 0 to 32 km/h in 5 seconds. The AVS 54's gearbox comes equipped with a hydrokinetic retarder, allowing deceleration at a rate of 7 m/s2. This system is automatically employed anytime speed in excess of 30km/h is reached. The AVS 54's exhausts exit at the rear left of the chassis and is cooled to reduce the thermal signature of the tank. Internal fuel capacity is 1300 liters.
Armament
The AVS 54 is equipped with the GIST-CN120-52/2 120mm smoothbore cannon. The cannon is capable of firing a variety of Notreceauen manufactured rounds including APFSDS with a tungsten core, HEAT, and HE. The gun is fitted with a thermal sleeve and features a proprietary compressed air-fume extraction system which functions automatically upon firing the weapon. The turret of the AVS 54 was designed around the proprietary Auto-loading system allowing the removal of the human gunner and reducing the crew to 3 was eliminating many of the size and space constraints placed on other MBTs featuring autoloaders.
The AVS 54's autoloader is capable of 12 shots a minute and contains 22 ready rounds. The autoloader can facilitate up to 8 different types of rounds, however a ready round cannot be unloaded from the gun once chambered. 120mm gun is 52 calibers long instead of the traditional 44 calibers common on most 120mm guns of its generation. This added length allows for firing rounds with a greater muzzle velocity than many contemporary cannons.
The AVS 54 features a .50 caliber MAP 54 machine gun with 1200 rounds as its coaxial and a MAP 50 7.5×54mm coaxial machine gun with 3000 rounds mounted on a remote weapon system (beginning with Séries III).
