The Challenger 3 Main Battle Tank (MBT), developed by Rheinmetall BAE Systems Land (RBSL), is set to replace the aging Challenger 2 tanks. This transition comes under a robust £800 million contract awarded in 2021, which includes the delivery of 148 state-of-the-art tanks equipped with modern technology enhancements. These upgrades include a fully digitalized system, improved armor protection, and a new 120mm smoothbore gun designed to bolster the tank's combat efficiency.
One of the standout features of the Challenger 3 is its main armament, the German-designed 120mm L55A1 gun, which is akin to the American M256 but with a longer barrel. This design choice enhances the tank’s ability to penetrate heavier armor from greater distances, although it also increases the tank's overall length, posing challenges in dense terrains such as forests.
The switch from a rifled barrel to a smoothbore gun aligns the British tank with standard NATO armaments, resolving past limitations where British tanks could not interchange ammunition with their allies. This compatibility with NATO standard ammunition is expected to offer strategic flexibility and logistical advantages during combined operations.
The 120mm L55A1 high-pressure gun, based on the L55 model, stands as the most advanced smoothbore gun globally, offering unparalleled pressure levels that enhance the performance of high-performance ammunition. Since its qualification and deployment in service in 2019, it has significantly boosted the firepower and lethality of the main battle tanks equipped with it. Compatible with existing systems in service on the Leopard2 and other MBTs, the L55A1 can be seamlessly integrated as an upgrade. Additionally, a programming kit necessary for the 3-mode programmable HE-round DM11 is available as an optional enhancement.
The L55A1 cannon excels in using Rheinmetall KE (Kinetic Energy) ammunition, which includes a high-strength tungsten penetrator, yielding superior performance against modern main battle tanks equipped with reactive armor as well as those with multi-layered and composite arrays. This state-of-the-art penetrator is designed to withstand extreme cutting and bending forces induced by double-reactive armor. Moreover, its integrated incendiary unit proves effective behind armor, offering considerable efficacy against both light and medium armored vehicles.
Furthermore, the L55A1 is capable of firing the DM73 APFSDS (Armour-Piercing Fin-Stabilized Discarding Sabot), a next-generation KE round that features an enhanced propulsion unit. The heightened pressure capabilities of the L55A1 gun allow for increased muzzle velocity compared to the DM63A1 in an L55 configuration, extending the range of engagement against modern MBT threats.
The L55A1 also supports various other types of ammunition, including the HE-FRAG-T DM11 (High Explosive Fragmentation), primarily used against enemy armor, and the HE-FRAG-T RH31, which employs the DM11 warhead to deliver similar effects upon detonation at the target point.
Additionally, the secondary armament of the Challenger 3 tank comprises a coaxial 7.62mm L8A2 machine gun mounted to the left of the main armament. A 7.62mm L37A2 machine gun can also be mounted at the commander's cupola, providing versatile defensive capabilities.
The Challenger 3's tank integration of the Rheinmetall 120mm L55A1 gun significantly boosts its combat effectiveness by allowing it to engage and penetrate the latest generation of tanks and combat armored vehicles at extended ranges.
