The K2 Black Panther (Hangul: K2 '흑표'; Hanja: K2 '黒豹') is a South Korean main battle tank that will replace most of the M48 Patton tanks and complement the K1 series of main battle tanks currently fielded by the Republic of Korea. Mass production commenced in 2013 and the first K2s were deployed with the armed forces in June 2014. The K2 costs over US$8.5 million per unit.[2][3]

Development

In 1995, the South Korean Agency for Defense Development (Hangul: 국방과학연구소) was given the task of developing a modern armored fighting vehicle based upon Korean state-of-the-art domestic technologies. It was intended for this development program to further modernize the Republic of Korea Army; despite the superior capability of existing K1 and K1A1 designs versus existing North Korean tanks; most of which are aging T-55s and Type 59s. Emphasis upon indigenous technologies would also allow the proposed vehicle to enter the export market without licensing issues.

Early design variants included a version with an unmanned turret, which was later scrapped in favor of manned turret designs. It was also planned for the vehicle to be equipped with Rheinmetall's experimental 140 mm smoothbore gun, though this had to be abandoned when Rheinmetall ceased development upon the rationale that its current weapon, the 120 mm/L55 would be more than adequate to counter prospective armored threats for the foreseeable future. The K2 was subsequently reconfigured for the 120 mm/L55, though it is capable of mounting the 140 mm gun with minimum modifications should the need arise.

The design became production-ready in 2006, following 11 years in development and a research budget expenditure of approximately US$230 million, and entered production phase on March 2, 2007 in Changwon, South Korea.

It was planned that the K2 would feature a domestically-designed powerpack, based upon the German-designed MTU-890, comprising a Doosan Infracore Corporation 1,500 horsepower (1,100 kW) 12-cylinder diesel engine and a S&T Dynamics transmission. However, this encountered recurrent technical trouble in testing, leading to a delay in operational deployment of the K2 for 2 years.

In March 2011, South Korea's Defense Acquisition Program Administration (DAPA) announced that mass production of the K2, which the Army was expecting to deploy in 2012, would not happen due to problems concerning its engine and transmission.[4] In April 2012, DAPA announced that due to ongoing issues with the reliability and durability of the domestically-produced powerpack, the first 100 production K2s would use German-made MTU powerpack and that service entry would be delayed until March 2014.[5]

On 26 September 2014, the K2 was demonstrated to 40 foreign military visitors from 9 countries at DX Korea 2014. When compared to the K1A1 tank, the K2's main gun reloaded quicker and reached targets faster. Although both are 120 mm, the K2's barrel is 1.3 m (4.3 ft) longer (6.6 m (22 ft) total length), resulting in a higher muzzle velocity of 1,400 m/s (4,600 ft/s) (compared to 1,140 m/s (3,700 ft/s) for the K1A1) for higher accuracy and armor penetration. Other features demonstrated included the tank's ability to cross a 4 m (13 ft)-deep river, a posture control function that can lower its height by 40 cm (16 in), and a laser warning systems that turned the turret towards the source almost instantaneously. Personnel from Hungary and others expressed interest in the K2 after the event.[6]

The first 15 K2 Black Panther tanks were put into service in June 2014. Faulty indigenous engines and transmissions previously halted production, but the lowering of required acceleration performance allowed it to enter service. The "power pack" of tank is intended to be locally developed. Until that occurs, they will employ German-made MTU power plants, making possible the deployment of around 100 K2s by 2017.[7][8] Tanks under the second contract, after the first 100 models, will be built with the domestic Doosan DST 1,500 hp engine and S&T Dynamics automatic transmission, beginning delivery in late 2016.[9]

Weapon systems

Main armament: The Black Panther is armed with a Rheinmetall 120 mm L/55 smoothbore gun. This gun is license-produced in South Korea.[10] This is complemented by an autoloader, similar to that designed for the Leclerc tank; it can fire up to 10 rounds a minute.[11] The ammunition for the main gun is loaded in a 16-shell magazine. The tank has a total ammunition capacity of 40 rounds for its main armamment.

Secondary weapons: 12.7 mm M2 Browning heavy machine gun; 7.62 mm coaxial machine gun.

Fire-control system and optics

The K2 is equipped with an advanced fire-control system (FCS) linked to an Extremely High Frequency radar system deployed on the frontal arc of the turret, along with a traditional laser rangefinder and crosswind sensor. The system is capable of a "lock-on" mode, which can acquire and track specific targets up to a range of 9.8 km using thermographic camera. This allows the crew to fire accurately while moving as well as engage low-flying aircraft.

The FCS is also linked to an advanced gun stabilizer and trigger-delay mechanism to optimise accuracy while moving in uneven terrain. Should the trigger on the main gun be pulled at the moment the tank encounters an irregularity in the terrain, oscillation of the gun barrel will cause temporary misalignment between a laser emitter at the top of the barrel and a sensor at the base. This will delay the FCS from activating until the beam is re-aligned, improving the chances of hitting the intended target.

The Korean Gunner's Primary Sight (KGPS) and the Korean Commander's Panoramic Sight (KCPS) are present in the Black Panther as in the original series of K1A1 tanks, though modified to utilise the more advanced sensors and armaments deployed on the K2.

The commander of the tank has the ability to override the command to take control of the turret and gun from the gunner. Moreover, unconfirmed reports state that, in the event of an emergency, the vehicle can be operated by only two crew members, or even a single one. It is speculated that the FCS can automatically spot and track visible targets, compare them using the data link established with other friendly vehicles to prevent redundant target engagements, and fire its main gun without manual input.

Munitions

The K2's primary anti-tank munition is an indigenously developed improved tungsten APFSDS kinetic energy penetrator, which offers significantly greater penetration than the current generation of tungsten rounds through better heat treatment of the tungsten alloy and the deformation-free self-sharpening that the penetrator undergoes as it penetrates the armour of its target.

The Korean Smart Top-Attack Munition (KSTAM) is a fire-and-forget, top-attack anti-tank munition with an effective operating range of 2–8 km, developed specifically for use with the K2. It is launched as a kinetic energy projectile, fired from the main gun in a high trajectory profile comparable to that of a mortar. Upon reaching its designated target area, a parachute deploys, giving on-board millimeter band radar, Infrared and radiometer sensors time to seek and acquire stationary or moving targets. When a target is acquired, an explosively formed penetrator is fired from a top-down position, to exploit the weaker top armor of tanks. Target acquisition can also be directed manually by the tank crew via a remote link. These characteristics allow the launch vehicle to remain concealed behind cover while firing successive rounds towards the known location of an enemy, or provide effective indirect fire support against targets hidden behind obstacles and structures.

For attacking unhardened targets, the K2 can use a multi-purpose HEAT chemical energy round, similar to the U.S. M830A1 HEAT MP-T, providing good offensive capabilities against personnel, unarmored and lightly armored vehicles on the ground as well as low-flying helicopters.

Defensive capabilities

Details of the composite armor of the Black Panther are classified. The frontal armor has been proven to be effective at defeating the 120 mm APFSDS round fired from the L55 gun. Explosive Reactive Armor blocks are also present, with the addition of Non-Explosive Reactive Armor planned for the K2 PIP version.

Defense against incoming missiles is provided by a soft-kill anti-missile system. The K2 PIP will likely deploy a hard-kill anti-missile defense system when it is released within the next few years.

The millimeter band radar system mounted on the turret is capable of operating as a Missile Approach Warning System (MAWS). The vehicle's computer in turn can triangulate incoming projectiles, immediately warn the vehicle crew and fire off Visual and Infrared Screening Smoke (VIRSS) grenades, which can effectively block optical, infrared and radar signatures. Once the hard-kill AMS is installed, the radar system will also be responsible for tracking and targeting the incoming missiles for the AMS.

The K2 also has a Radar Warning Receiver (RWR) and radar jammer. Four all-bearing Laser Warning Receivers (LWR) are also present to alert the crew should the vehicle become "painted", and the computer can also deploy VIRSS grenades towards the direction of the beam.

An automatic fire suppression system is programmed to detect and put out any internal fires that may occur, and atmospheric sensors alert the crew if the tank enters a hazardous environment.

Mobility and maneuverability

The K2 can travel at speeds of up to 70 km/h on road surfaces, accelerate from 0 to 32 km/h within 8.7 seconds,[12][13][14] and maintain speeds of up to 52 km/h in off-road conditions. It can also climb 60-degree slopes and vertical obstacles 1.8 meters in height. Due to the relatively compact design of the engine, the designers were able to fit an additional Samsung Techwin gas-turbine engine into the remaining compartment space. This is capable of producing 100 horsepower (75 kW), and intended to act as an auxiliary power unit with which the tank may power its on-board systems when its main engines are turned off. It will also allow the tank to conserve fuel when idling and minimise the vehicle's thermal and acoustic signatures.

The vehicle can cross rivers as deep as 5 meters using a snorkel system, which also serves as a conning tower for the tank commander. The system takes approximately 30 minutes to prepare. The turret becomes watertight while fording, but the chassis can take in 500 gallons of water to prevent excessive buoyancy from air inside the vehicle and keep the tracks planted firmly on the ground. Furthermore, the tank can enter combat-ready status as soon as it resurfaces.

The Black Panther fields an advanced suspension system, called the In-arm Suspension Unit (ISU), which allows for individual control of every bogie on the tracks. This allows the K2 to "sit", "stand" and "kneel", as well as "lean" towards one side or a corner. "Sitting" gives the tank a lower profile and offers superior handling over roads. "Standing" gives the vehicle higher ground clearance for maneuverability over rough terrain. "Kneeling" augments the angular range in which the tank's gun barrel can elevate and depress, allowing the vehicle to fire its main gun downhill as well as engage low-flying aircraft more effectively. The suspension unit also cushions the chassis from vibrations when travelling over uneven terrain, as the bogies can be adjusted individually on-the-fly.

Network-centric considerations

The K2 houses the following features which help to improve situational awareness for the crew:

Work is also under way to integrate the XAV unmanned wheeled reconnaissance vehicle into the Black Panther's systems, giving the tank's crew the ability to remotely scout an area without exposing its position.

K2 product improvement program

The K2 PIP is an improved version of the initial production model of the K2 that will be released within the next few years. Improvements will include:

KAPS

The Korean Active Protection System (KAPS) is an indigenously developed hard-kill active protection system designed to protect the K2 from anti-tank threats. It uses a three-dimensional detection and tracking radar and a thermal imager to detect incoming threats. Warheads can be detected out to 150 meters from the tank, and a defensive rocket is fired to destroy them at 10–15 meters away. The KAPS can neutralize rocket-propelled grenades and anti-tank guided missiles. The system may be installed on other platforms in the future like warships, helicopters, and buildings. Unit price per system is ₩670 million ($600,000).[15]

Export

See also: MİTÜP Altay

After competing against the Leclerc and Leopard 2, the K2 established its first export customer in Turkey. In June 2007, South Korea and Turkey successfully negotiated an arms deal contract worth ₩500 billion (approximately US$540 million) licensing the design of the K2, as well as exporting 40(+15) KT-1 trainer planes to Turkey.[16]

On July 30, 2008, South Korea's Hyundai Rotem and Turkey's Otokar signed a contract worth $540 million for technological transfer and design assistance. The technology is to be incorporated to Turkey's own indigenous future main battle tank, dubbed MİTÜP Altay. Despite sharing many subsystems with the K2, such as protective armor and main gun, it is expected to feature a different look and have different performance characteristics. Turkey required partial dissolution of contractual coverage from the South Korean national-defense agency in January, 2011 for reasons of the delay in development.

In late September 2013, South Korea entered the K2 Black Panther in the Peruvian Army's future tank competition.[17]
