RCH 155 (Remote-Controlled Howitzer 155 mm)

The RCH 155 (Remote-Controlled Howitzer 155 mm) is a modern wheeled self-propelled artillery gun (or howitzer) manufactured by KNDS Germany (formerly Krauss-Maffei Wegmann).

Development of the RCH 155 (Remote-Controlled Howitzer) was undertaken by the German defense company Krauss-Maffei Wegmann (now KNDS Germany) between 2014 and 2024.

Prior to the RCH 155, the German manufacturer had developed an autonomous, automated artillery turret system known as the Artillery Gun Module (AGM). The AGM weapon system utilized the 155mm L52 caliber gun barrel from Germany's legendary tracked howitzer, the PzH 2000. In 2014, KMW decided to integrate this unmanned AGM module onto the chassis of the GTK Boxer 8×8 wheeled combat vehicle. This combination aimed to create an artillery system with destructive power comparable to the PzH 2000, yet offering significantly higher strategic mobility and operational speed on roads. The RCH 155 prototype was first unveiled to the global public at the Eurosatory 2016 international defense exhibition in Paris. Following years of live-fire testing and the refinement of its computerized systems, the system officially entered mass production in 2022.

The following are some of the key specifications and advantages of the RCH 155:

"Shoot-on-the-Move" Capability: This is its most revolutionary feature; the gun is capable of accurately aiming and firing rounds while the vehicle is in motion.

Full Automation: The system employs a fully automated loading mechanism (autoloader), allowing the gun within the turret to be operated remotely by a crew seated in a protected cabin. Minimal Crew: Requires a crew of only two (commander and driver) to operate the entire weapon system.

Firepower and Range: Utilizes a 155 mm L52 barrel with a firing range of approximately 40 km using standard ammunition; it can reach distances exceeding 54 km—up to 76 km—with advanced guided munitions (such as Excalibur or Volcano) and boasts a firing rate of up to 9 rounds per minute.

No Stabilizer Legs: The turret is capable of 360-degree rotation and firing in any direction without the need for additional stabilizer legs prior to engagement.

Weaknesses and drawbacks considered by military experts:

Very Heavy Weight: The Artillery Gun Module (AGM) mounted on the Boxer chassis brings the RCH 155's total weight to approximately 39 tons. This is significantly heavier than competing wheeled howitzers like the CAESAR (France), which weigh only around 18–32 tons.

Limited Air Mobility: Due to its large size and weight approaching 40 tons, the RCH 155 cannot be transported by standard NATO tactical transport aircraft such as the C-130 Hercules. It requires much larger strategic transport aircraft, such as the Airbus A400M or Boeing C-17 Globemaster III, for air transport.

Very High Cost: Given its cutting-edge automation technology, fire stabilization system, and complex Boxer chassis, the unit cost of the RCH 155 is far higher than that of other conventional self-propelled artillery systems.

High Reliance on Electronic Systems: The entire process—from ammunition loading and targeting to firing—is digitally controlled and fully automated (remote-controlled). In the event of an electronic system failure, computer damage from a cyberattack, or an EMP (Electromagnetic Pulse) strike, the gun system risks total incapacitation, as manual operation by the crew—who are located in a separate cabin—is difficult.

Limited Ammunition Capacity: The AGM automated turret carries only 30 ready-to-fire rounds in its magazine. During prolonged, high-intensity combat, the RCH 155 relies heavily on nearby ammunition supply vehicles.

High Vehicle Profile: The large, unmanned turret design results in a vehicle height of nearly 4 meters. This high profile makes it easier for enemy radar or reconnaissance drones to detect the vehicle in open terrain compared to lower-profile artillery systems.

User and Ordering Nations: To date, hundreds of RCH 155 units have been ordered by several countries to modernize their field artillery fleets:

- Ukraine: The first nation to operate the system. Ukraine ordered a total of 54 units, funded through German military aid. The initial units have reportedly arrived and are undergoing live battlefield testing (combat-proven).

- Germany: The Bundeswehr (German Army) conducted intensive testing and committed to ordering the system—alongside the UK—as part of strengthening the NATO alliance.

- United Kingdom: In May 2026, the UK government finalized a contract worth nearly £1 billion to purchase 72 RCH 155 units.

- Switzerland: In June 2026, the Swiss Army officially selected the RCH 155 and ordered 32 units.

- Qatar: Confirmed the purchase of the RCH 155 from Germany.

The Type 99 MBT (ZTZ-99) - Chinese third-generation Main Battle Tank

The Type 99 MBT (ZTZ-99) is a third-generation Main Battle Tank (MBT) of Chinese manufacture, produced in large numbers to modernize the country's ground forces. The Type 99 replaced the Type 88 tank and entered service with the Chinese People's Liberation Army (PLA) in 2001.

Key Specifications and Advantages

Main Armament: A 125mm ZPT-98 smoothbore gun equipped with an autoloader and the capability to fire anti-tank guided missiles (ATGMs). 

Protection: Utilizes modular composite armor and Explosive Reactive Armour (ERA) to withstand tandem-warhead attacks; it is also equipped with a laser warning system or laser dazzler to disrupt enemy optics. 

Mobility and Technology: Powered by a high-output turbocharged engine and featuring an advanced digital fire-control system for high battlefield accuracy.

The development of the Type 99 MBT was driven by the Chinese military's need for an indigenous third-generation main battle tank capable of rivaling modern Western and Russian tanks. 

Origins (1980s): The project officially began in the late 1980s (under China's Eighth Five-Year Plan) through the defense research agency NORINCO. Chinese designers extensively studied the chassis and autoloader mechanisms of the Soviet T-72 tank, integrating them with Western technologies (such as German engine systems and digital fire-control systems). 

Lessons from the Gulf War (1991): The destruction of Iraqi tanks—which were older Soviet and Chinese-made variants—by US-led coalition forces during Operation Desert Storm served as a wake-up call for Beijing. This accelerated China's research into delivering state-of-the-art composite armor protection and integrated digital systems. 

Type 98 Prototype (1999): The tank's initial prototype was known as the Type 98 (WZ-123). It was first revealed to the public during China's National Day parade on October 1, 1999. 

Official Service (2001–Present): Following refinements to its armor and engine, the tank was officially designated the Type 99 (ZTZ-99) and entered operational service with the Chinese Army in 2001. In 2015, China launched the Type 99A variant—a comprehensively upgraded version featuring a much thicker, arrow-shaped turret and a more advanced computerized battlefield system.

China has never exported the Type 99 to other countries for several key reasons: 

Classified Technology: The tank incorporates Beijing's highest-tier military technology, including secret composite armor and an active laser protection system designed to counter missiles. 

High Production Costs: Its exorbitant price tag led China to limit production numbers (estimated at around 1,200 to over 1,300 units) and opt instead for the more economical Type 96 tank as the backbone of its armored forces.

To date, the Type 99 MBT has never seen actual combat, despite being one of the most advanced main battle tanks in Asia. China has not engaged in large-scale ground warfare since this tank officially entered service in 2001. Furthermore, because China prohibits the export of the Type 99, the tank has never been used by other nations in regional conflicts in the Middle East or Africa—unlike its rivals, such as the Russian T-90 or the US M1 Abrams, which are frequently deployed to the battlefield by the countries that purchased them.

The Type 15 tank - Black Panther, Chinese light tank

The Type 15 tank (also known as the ZTQ-15 or nicknamed "Black Panther") is a third-generation Chinese light tank developed by NORINCO. It was specifically designed to operate in challenging terrain—such as highlands, mountainous regions (like Tibet), forests, and wetland areas—where heavy Main Battle Tanks (MBTs) struggle to maneuver.

Key Characteristics and Specifications

Mobility and Weight: It weighs approximately 33 to 36 tons. This light weight facilitates transport by military cargo aircraft, enabling rapid deployment.

Main Armament: It is equipped with a 105mm rifled gun featuring an automatic loading system (autoloader). The gun can fire various types of anti-tank ammunition and guided missiles, with an effective range of 3–5 km.

High-Altitude Engine: It is powered by a 1,000-horsepower (hp) diesel engine. The engine utilizes a modular turbocharged system to compensate for low oxygen levels at high altitudes, ensuring performance does not degrade.

Protection System: It features composite armor and modular add-on steel armor, including Explosive Reactive Armor (ERA) and cage armor designed to withstand anti-tank rocket attacks. The tank is also equipped with laser warning sensors as part of its passive defense system.

Efficient Crewing: Thanks to the automatic ammunition loading system, the tank requires a crew of only three personnel (commander, gunner, and driver).

The development of the Type 15 (ZTQ-15) tank was driven by China's strategic geographic military requirements.

Between the late 2000s and early 2011, the Chinese Army (PLA) recognized that its existing light tank fleet—the Type 62—had become severely obsolete (having been introduced in 1963). On the other hand, their mainstay Main Battle Tanks (MBTs)—such as the Type 96 and Type 99—are excessively heavy (weighing between 42 and 58 tons). Heavy MBTs cannot operate effectively in China's rugged southwestern border regions, characterized by high, rocky mountains (such as Tibet and Xinjiang), because the thin air causes standard tank engines to lose power. Heavy MBTs also struggle to traverse the dense forests or marshlands found in the south.

The state-owned defense company NORINCO held an internal competition to design a next-generation light tank. The winning design was specifically developed for China's domestic military as the ZTQ-15. Meanwhile, the losing design was not discarded but instead modified into a commercial variant for the export market, designated the VT5.

Mass production began around 2016. Its existence was first confirmed by the Chinese Ministry of National Defense in December 2018, and it was grandly unveiled to the world during the 70th National Day military parade in Beijing on October 1, 2019. The tank proved crucial when deployed to the Tibetan plateau border during tensions with India in mid-2020.

User Nations: 

Currently, operators of the Type 15 tank are divided into users of the domestic version (ZTQ-15) and users of the export version (VT5):

China (Primary User)

Operated extensively by the People's Liberation Army (PLA). Hundreds of units are actively used by specialized units, namely: PLA Ground Force: Stationed within the Xinjiang and Tibet Military Commands to guard high-altitude regions. PLA Navy Marine Corps: Used for high-speed amphibious landing operations. PLA Air Force Airborne Corps: Due to its light weight, the tank can be airdropped from military cargo aircraft.

Bangladesh

Bangladesh became the first foreign nation and the inaugural export customer to purchase this tank. The Bangladesh Army ordered the VT5 variant (approximately 44 units) because the tank's characteristics were deemed highly suitable for traversing the marshy terrain, rivers, and muddy ground typical of South Asia—areas that are difficult for heavy Main Battle Tanks (MBTs) to navigate.
