Rotem introduced the vehicle along with its wheeled armoured vehicles and unmanned weapon systems at the Seoul Aerospace and Defence Exhibition (ADEX) at the Seoul Airport in Seongnam City, Kyeonggi Province, in October 2009. The tank is expected to enter into service in 2014.

The K2 Black Panther is a new type of high tech battle tank and will replace K1 series of vehicles and M48 tanks. The new MBT features enhanced mobility and fire power compared to the K1 vehicles, and is regarded as one of the best main battle tanks in the world.

K1A1 MBT

K1 Republic of Korea Indigenous Tank (ROKIT)

The K1 has been operational in the RoK Army since 1986 and is known as the Republic of Korea Indigenous Tank or ROKIT. Following early design work based on US M1 technology, the K1 tank was designed and produced by Korea. The manoeuvrability of the tank is optimised for the varied geographical features of Korea, which include mountainous terrain, jungle, paddy fields and swamp.

The main gun is a 105mm rifled high-velocity cannon with a coaxial 7.62mm machine gun. The commander’s station is equipped with a 50-calibre machine gun and the loader’s station with a 7.62mm machine gun. The turret slews at 750mm a second and elevates and depresses at 400mm a second.

The commander’s panoramic sight has three modes of operation: align with the main armament, independent tracking and gunner override. The commander has the option of handing off the target to the gunner or of slaving the gun to the commander’s sight and initiating the fire. The K1 has demonstrated a first round hit probability of greater than 90% when firing on the move at a moving target.

The Raytheon Gunner’s Primary Sight Subsystem (GPSS) is stabilised in two axes and includes a thermal imager and laser rangefinder. The gunner’s ballistic computer automatically downloads crosswind data, vehicle cant, azimuth tracking rate and range. The gunner manually inputs data for air pressure, air temperature, barrel wear, barrel droop and ammunition type.

PROPULSION

The Kl is equipped with a turbo-charged 1,200hp MTU MB 871 diesel engine providing a power to weight ratio of 23.5hp/t.

MTU MB 871 diesel engine

MB871 Ka-501 engine, with 1200ps at 2600rpm 8-cylinder version, and MT881 Ka-500 engine, 8-cylinder version, has been locally produced by STX since the year of 1986 under the manufacturing license from MTU, Germany. These engines are not only best optimized for the military vehicles with its size compactness and lightness but also provided superior operational economics mainly thanks to the comparably lower fuel consumption rate, longest MTBO and well-organized logistics system. @army-guide.com

The transmission has a planetary gear train and a hydrodynamic torque converter. In high gear, the Kl can attain a maximum road speed of approximately 65km/h. The low ground pressure of 0.87kg/cm² enables it to successfully manoeuvre in sodden or sandy terrain.

The Kl has hydro-pneumatic suspension and torsion bar springs. The suspension system also provides vehicle attitude control or ‘kneeling’ capability, which increases the main gun depression angle to a maximum of minus 10°. @army-technology.com

The K2 Black Panther development

The K2 MBT design was completed in 2006. Rotem signed a co-operation agreement in March 2011 with the subcontractors of K2 MBT and provided KRW12.8bn ($12m) to solve the financial difficulties caused by delays in the mass production of the vehicles.

Rotem signed a contract with the subcontractors in November 2011 to offer emergency operating funds totalling KRW3bn ($2.65m). The mass production of K2 MBTs was further delayed due to technical defects in engines and transmission.

In July 2008, Rotem signed a technology cooperation deal with Otokar to provide technology systems of the K2 MBT for the development of Turkey’s Altay Main Battle Tank. The first prototype of the Altay MBT is expected to be ready by 2015.

Armament of the K2 Black Panther

The main armament of the K2 Black Panther is a 120mm L/55 smoothbore gun with automatic loader. The autoloader ensures the loading of projectiles on the move even when the vehicle moves on uneven surfaces. The 120mm gun can fire about 10 rounds per minute.

The Black Panther is armed with a Rheinmetall 120-mm/ L55 smoothbore gun. This gun is license-produced in South Korea. @military-today.comK6 12.7-mm heavy machine gun

The secondary armament of the tank includes a 12.7mm heavy machine gun and a 7.62mm machine gun.

“It is worth mentioning that autoloader’s is similar to that, used on the French Leclerc main battle tank. A total of 16 rounds are stored in the autoloader. Remaining 24 rounds are stored inside the hull.

It also has a very advanced fire control system, allowing to track and engage not only the main battle tanks, but low-flying helicopters as well. Maximum effective range of fire is up to 10 kilometers. Furthermore its fire control system can spot, track and fire automatically at visible vehicle-size targets without needing any input from a human operator.” @military-today.com

The K2 Black Panther autoloader

“The K2 and Type 10 are the only tanks I heard of that can use DM 53 tier APFSDS in autoloaders, which is amazing considering only DM 43 tier or so was used in the Leclerc. Autoloaders tend to be shafted in terms of penetration from what I can tell, usually because the ammo is too long for the autoloader.” @aw.my.com

“The gunner is seated on the left side of the turret with the commander to his right. Gunner has a dual-axis stabilized sight with auto-tracking capability and the commander has a panoramic stabilized sight to allow hunter-killer type operation. Turret has an onboard ammunition capability of 16 120mm rounds. Additional 24 rounds are stored in the hull.” @WARFARE TECHNOLOGY

See video below for comparison of tank autoloader’s

“The 120-mm gun can fire variety of munitions. It is compatible with all standard NATO tank rounds. It is also capable of firing the new KSTAM (Korean Smart Top-Attack Munition) rounds. These are smart target-activated fire-and-forget projectiles, but shouldn’t be confused with anti-tank guided missiles. The KSTAM has its own guidance system, aided by four stabilizing fins. At the final stage a parachute will deploy to slow its fall and accurately engage target. Such principle is broadly similar to mortar-launched anti-tank munitions. Furthermore the K-2 tank can fire KSTAM munitions from behind the cover. The KSTAM has a maximum effective range of 8 kilometers.” @military-today.com

untitledKSTAM (Korean Smart Top-Attack Munition) @dogswar.ru444-hhj666

“Basically a guided anti-tank mortar munition, the KSTAM flies with the energy applied to it from the firing of the munition from the main gun. It does not possess any kind of propellants, and should not be confused as a missile or a rocket. The trajectory of the munition is curved, giving it a mortar- or artillery-like capability to strike targets taking cover behind obstacles. Its main use is to destroy entrenched and/or covered enemy vehicles that are unreachable with regular anti-tank shells due to the restrictions in terrain and/or hazards imposed upon the friendly vehicle.” @wikipedia.org

Sensors and other systems of K2 Black Panther

The K2 Black Panther is equipped with auto target detection and tracking system, and hunter killer function. It also features electric gun and turret driving system (28-260VDC) provided by Doosan Corporation Mottrol.

The gunner’s primary sight (GPS) and commander’s panoramic sight (CPS) are stabilised in two axes, and include a thermal imager and laser rangefinder enabling day / night observation.

First exports of Thales’ Fulmar UAVs are going to the Malaysian Maritime Enforcement Agency.

Mar 21, 2016 00:59 UTC by Defense Industry Daily staff

First exports of Thales’ Fulmar UAVs are going to the Malaysian Maritime Enforcement Agency. The Malaysian shipbuilder has contracted Thales to deliver six of the mini-UAVs, which will be used for surveillance, reconnaissance, and border control missions, and is expected to cost around $1.1 million. Fulmar works with a catapult-based launcher system and net landing capability. It is available for use with a variety of fuel types such as diesel oil, JP8 and JP5, approved for use on combat ships. Thales are expected to produce up to 25 models over the next two years, with the company pushing its use by Spain’s Military Emergencies Unit and the Naval Infantry Force.

****-END-****

Thales’ Fulmar UAVs

Fulmar is classified in the mini-UAV segment. Its size is 3.1 meters and weighs 19 kilos, it flies to the altitude of 3,000 meters and can achieve a speed of 150 kilometers per hour. It has a range of eight hours due to a low consumption of the aircraft in flight as a result of its aerodynamic design, and it can fly 800 km without refueling.

This Spanish design counts on a terrestrial and a maritime version. Fulmar is purely Spanish, contributing with a profitable closeness to equipment maintenance as well as to operators’ training.

Fulmar is a competitive solution that can be adapted to different needs and can integrate with other systems to provide a global solution. @thalesgroup.com

CAEW Conformal Airborne Early Warning Aircraft – G550 airframe

The Israel Aerospace Industries (IAI) conformal airborne early warning and control (CAEW) aircraft was first unveiled in public at the UK’s 2008 Farnborough Air Show. The prime contractor, system developer and system integrator for the CAEW is Elta Systems Ltd, a subsidiary of IAI.

The CAEW aircraft is based on the G550 airframe from Gulfstream Aerospace of the USA. The operationally proven G550 CAEW aircraft is the third generation of airborne early warning and control systems developed by IAI Elta since the mid-1980s.

3-caew-aircraftGulfstream G-550 Aircraft AEW

Gulfstream was awarded a contract for four (plus two options) G550 modified aircraft in August 2003. First flight of the modified aircraft was in May 2006 and it was delivered to Elta for the installation of the mission systems in September 2006. The first and second CAEW aircraft were delivered to the Israel Air Force in February and May 2008 and since then have been in operational use.

In Feburary 2009, the Singapore Air Force recieved four CAEW aircraft from Elta Systems. The aircraft, worth $1bn, will replace four aging Northrop E-2Cs currently in service with the air force.

The Singapore Air Force has also ordered a number of CAEW aircraft to be delivered during 2009 and 2010.

CAEW modifications on Gulfstream G550

The CAEW provides improved performance in terms of higher operating altitude, longer range and increased time on station. The main AEW performance advantages result from the capability to point the radar beams in any direction in space at any time, with the beam’s parameters controlled by the radar computer. The CAEW aircraft is based on the Gulfstream G550 airframe, which is an upgraded variant of the Gulfstream V-SP with improved aerodynamic performance. The aircraft is manufactured at the Gulfstream business jet production centre in Savannah, Georgia, USA and transferred to IAI Elta Systems Ltd in Ashdod, Israel.
