The Tarskvagn-141 (TskVg-141) is a domestically produced Main Battle Tank from Dniegua. Intended to supplement the Tarskvagn-124 in armored units, and later replace it all together, the Tskvg-141 represents a major leap in armored capability and design in the 20th century. Commonly called the T-vagn (T-wagon), the TskVg-141 is armed with a 145mm L/55 smoothbore gun with 32 rounds, as well as a Coaxial 40x364mm cannon for anti-aircraft and anti-infantry use. In addition, a coaxial 6.5mm Machine Gun and two mounts for commander and gunner weapon stations exist.

The TskVg-141 development started in the late 1980s as a plan to defeat modern evolving composite armors from longer ranges. Economic situations and issues slowed development as funds were diverted from armored projects to stop-gap solutions such as gun-launched anti-tank guided missiles (GLATGMs), which ensured little (if any) development took place through most of the early 1990s. The project was revitalized in the mid 1990s as it became apparent that current production MBTs would be unable to reliably fight and defend from next-generation main battle tanks. Prototypes entered trials in 2002, and the first vehicles were adopted in 2004. Today, Dniegua is the largest operator of the TskVg-141 with 1,600 in service, with plans to acquire over 1,000 more within the next decade.

History

The TskVg-141 project draws roots from a 1980s Dnieguan project to develop a next-generation tank cannon. Originally proposed to be 130mm in diameter, the gun would be fitted to a number of armored brigades tanks, which would allow them to engage enemy armor at longer distances and deliver a much larger payload. With the adoption of the TskVg-124, however, the project was scrapped, as it was believed the new tank was sufficient to fill all roles with its high-pressure 125mm gun. In 1987, the project was defended and effectively put to an end. However, in 1990, the Dnieguan Defense Ministry again contracted the same firms to design and draft the next generation of "heavy" tanks.

The firms contracted and deign teams had initially planned to use the 130mm gun designed from the previous project. However, the Defense ministry specified the gun should offer at least a 20% increase in performance over the current KkB-2 125mm gun. This resulted in the development of a 140mm smooth bore cannon, which offered a 40% increase in performance when firing Fin-Stabilized sabot ammunition.

The tank project posed several ambitious designs to meet several design goals. Colonel Bjorn Zicher headed up the design team. The tank needed to be as fast as current medium tanks while also armed well enough to defeat any contemporary at distances in excess of 2 kilometers, and protected along the front from contemporary anti-tank ammunition. It had to be able to fire in 360 degrees while on the move, and had to have the ability to survive an impact to the ammunition compartment.

In 1993 the projects funding had been slashed considerably, primarily to divert funds to stop-gap solutions for the current tanks. This caused great strain on the project teams, who were unable to build any functioning prototypes. However, in these years, the designs had been streamlined and made more efficient, eventually resulting in three possible designs. The first was a conventional 140mm smoothbore cannon in a remote turret mount, which would be raised and lowered by a remote operating arm to a height of up to 3.2 meters. When lowered, the tank was 2.3 meters. The second design was far more conventional, with the 140mm gun being encased in a traditional angular turret with 360 degree rotation, which had a height of 2.2 meters. The third design was reminiscent of case mate tank destroyers, with a limited degree of fire (18 degrees), but had the advantage of a low profile and very strong armor.

The projects revitalization in 2001 saw all three testbeds built. The third prototype, while innovative and very well protected, was disqualified due to its mechanical complexity and inability to fire in a 360 degree arc while on the move. Another problem showed quickly. The larger ammunition disallowed the tank from carrying large amounts of inboard ammunition, which posed an issue to the tanks firing solutions. Sometime later, the two prototypes were fitted with a 40mm coaxial autocannon for anti-infantry and anti-aircraft use, allowing the TskVg-141 to carry more dedicated anti-armor munitions. The autocannons were not fully integrated initially.

As the competition went on, it was determined both tanks had merits, and the designers returned to combine elements into the same tanks. In addition, a choise was made to drop development of the still in progress 140mm tank cannon and adopt instead a domestic made version of the Austrasien 14.5cm PzK M-85 L/45 cannon. The final prototype utilized a traditional angular turret with firing controls and an auto loader system from the remote turret, as well as the mounting system for the 40mm gun from the same. Through a series of refinements, this became the TskVg-141.

Design

Overview

The Tarskvagn-141 follows the traditional role of modern main battle tanks by being relatively mobile and compact while being well armed and armored. With a maximum combat weight of 62.6 tonnes, the tank has a maximum speed of 70km/h and a range of 500 kilometers. The 145mm L/55 cannon is a domestic variation of the same Austrasien cannon with a longer barrel system, in an effort to force a degree of standardization among members of the Skanderan Union. The tank carries 32 rounds, traditionally 26 M824A2 APFSDS and 6 M478A1 HEAT rounds. The 40mm Cannon sits on the side of the turret loaded with 156 40mm rounds in a dual feed system, loaded with 42 APFSDS projectiles and 110 HE.

A three pairs of road wheels of even spacing are enveloped by a relatively thick track on either side. The hull of the tank measures 6.8 meters long and is 3.7 meters wide, while the gun forward makes the tank 10.7 meters long. The tanks is 2.26 meters from ground to the top of the turret, though with remote weapons stations the tank may measure to 2.65 meters tall.

The tank offers total frontal protection from 130mm APFSDS projectiles and is resistant to 1,650mm of HEAT penetration after ERA effects. The top of the tank offers protection from 155mm EFPs. The engine of the tank sits in the middle of the hull. The transmission has six forward running gears and three reverse, allowing for a maximum backwards speed of 40km/h.

Cover and Concealment

The TskVg-141 has an especially low-profile, allowing for excellent hull-down positioning and camouflage. Painted in the standard M/90 Fractile camouflage pattern, crews are trained to utilize the terrain to better camouflage their tank. This includes covering the tank with mud, foliage, bark, branches or otherwise and allows crews to maintain especially low-profiles. A pair of two eight-barrel smoke discharges create a large area of smoke around the tank, concealing it from thermal view. In addition, a remote smoke generator activated by the driver, which creates a thick discharge of smoke in driving.

Protection

In addition to thick armor, many tanks are equipped with softkill munitions systems (Such as the Scantronic ITDS-D system), which allows them to passively defeat incoming anti-tank missiles. The systems impede the function of guidance systems of some semi-active control line-of-sight (SACLOS) wire- and radio guided anti-tank missiles and infrared homing missiles. This system works by emitting a massive, condensed infrared signal to confuse the infrared homing seeker of an anti-tank guided missile (ATGM).

In addition, an fire suppression system within the crew and ammunition compartment exists and is automatically activated when a series of remote sensors detect flame. Blow-out panels are in place to protect the crew should the tank ammunition cook off.

Operational History

Dniegua

The Tarskvagn 141s first use was with Dnieguan Naval Infantry units operating oversees with peacekeeping forces in various conflict zones. For the most part, these tanks acted as mobile fire support for infantry units and defensive maneuver elements, firing on fixed position, hardened structures and vehicles at extended range. Proving durability, the Tvagn 141 proved suitability by withstanding a large number of impacts from anti-tank rockets and missiles, including a friendly fire incident with a Pskott. M/48.

Battle of Drazen-My'sta

The first true combat tests of the Tarskvagn-141 occurred during Operation: Coin Toss when the 11th Armored Brigade of the Dnieguan XXVII Corps faced off against the Gratislavian VI Corps 6th Battalion 4th Armored's own Tarskvagn-141s, as well as the 24th Infantry Divisions M-84AS Main Battle Tanks. Superior active protection systems and training of Dnieguan crews largely eliminated anti-tank guided missile advantages of the Gratislavian M-84AS and encamped infantry, which were quickly eliminated outside of their guns maximum effective range. A Dnieguan Tank from B Squadron, F Troop, 2nd Armored Battalion successfully engaged an M-84AS at 4,680 meters.

Dnieguan and Gratislavian tanks found themselves unable to reliably penetrate one another at distances in excess of 1 kilometer. Superior Dnieguan artillery and air support forced Gratislavian forces to withdraw to the nearby town of Drazen, hoping to force Air Support of station due to the risk of hidden short-range air-defense systems. Dnieguan rangers provided laser designation for two on-station NkB-78 bombers, which destroyed a large number of armored units, missile sights, and structures. The armored unit then advanced into the outskirts and city proper, along with IpKVG-91s. At close range, effects were devastating, though bounces and failures to penetrate were frequently reported. In total, Gratislavia suffered twelve Tvagn 141s destroyed, while Dniegua lost three; one of which was lost after ramming and destroying a Gratislavian M84-AS. Twenty-eight Dnieguan tanks suffered mobility loss or critical systems failure but were still able to function, and one was scuttled by its crew. Gratislavian forces suffered a similar fate, with the remaining tanks being captured and are ongoing refit to enter the Dnieguan Forces; one retreating Gratislav crew surrendered to a V-256 Sagoska, beveling it to be hunting them, when it was merely lost itself. In total, 163 Gratislav tanks were captured, 48 were damaged beyond repaired and destroyed, and 56 evaded Dnieguan forces.

Temuair

The Imperial Army of Temuair made extensive use of the Tarskvagn-141 during the 2015 Invasion of Gratislavia. Specifically, the 4th Imperial Lancers Brigade, equipped with 280 Tarskvagn-141's, participated in the Battle of Bedero, engaging 228th Armored Brigade of XX Corps, also equipped with a total of 186 Tarskvagn-141 vehicles. The fighting within the city was vicious and saw the loss of numerous Aisling combat vehicles.

In combat against Gratislavian M-84AS, Aisling Tarskvagn-141's fared as well as their Dnieguan counterparts, inflicting severe losses on Gratislav formations by achieving penetrating shots outside of the M-84AS's maximum cannon range, and defeating gun launched ATGM's with their soft kill active protection systems. The only known damage inflicted upon Aisling Tarskvagn-141's came during the Battle of Bedero, where the fighting forced the vehicles into close proximity to one another, and the urban terrain allowed the enemy to more easily enrage the advancing Aisling tanks from ambush. Footage recovered from Aisling tanks pro ported to show that most engagement ranges were within less than 80 meters. In some instances, tanks were often literally within distances in which they were unable to traverse guns to fire, as the barrels collided with the opposing tanks hulls.

During the Battle of Bedero, Aisling losses including seventeen Tarskvagn-141 vehicles completely destroyed, while an additional forty-nine were severely damaged and forced to withdraw from combat.
