The RCH-155 module is very similar to the Artillery Gun Module (AGM, Artillerie-Geschütz-Modul), but has a lower profile. The AGM was designed to have the firepower of the PzH 2000 in an air-portable package with the A400M aircraft this was possible when installed on an ASCOD 2 platform, known as the DONAR. In 2014 with interest in installing the AGM on the Boxer, questions arose regarding its capacity to meet this requirement. In 2021, KMW produced a modified variant of the AGM, the RCH 155. The RCH 155 has a turret with a significantly lower profile.

The German launched a programme for a future wheeled artillery system known as the "Zukünftiges System Indirektes Feuer mittlere Reichweite" (ZukSysIndF mRw, "Future System Indirect Fire Medium Range"). In October 2023, the RCH-155 was mentioned as the winner of the competition, as the option from Rheinmetall (Artillery Truck Interface) was still in development and not yet mature. The target back then was hopefully for 168 systems, realistically the budget was for 120 systems. In December 2025, the Bundestag voted the budget for a framework agreement for 500 systems, more precisely: • 4 prototypes (1 for the UK, 3 for Germany) • Germany: • 80 RCH-155 to be ordered in 2025 • 149 to be ordered in 2026 • 271 available for export at German price condition. On 13 January 2025, Germany gave the first RCH 155 to Ukraine. KNDS will supply Ukraine with 54 RCH 155 wheeled howitzers, with the first six systems to be delivered in 2025.

The RCH 155 is the world's first howitzer that can fire while in motion. This is mainly to avoid enemy counter-artillery fire, as modern counter-battery radars such as COBRA can be used to reconnoitre fire positions after firing in near real-time. Its traverse and firing controls allow firing the gun at targets in the vicinity, such as an enemy tank, in a direct-fire, rather than indirect artillery mode. Taken together, quick acquisition of target, direct-fire and "shoot-and-scoot" capabilities mean the RCH 155 could be considered to have a hunter-killer role similar to main battle tanks as it is able to quickly acquire targets in line-of-sight and prosecute them while on the move, or at least moving quickly out afterwards without remaining open to easy counter-fire. This capability, however, is for self-defence and is not its main role. The RCH 155 is highly automated and is theorised to eventually be capable of operating entirely remotely.

It was presented at Eurosatory 2026, and will start the trials in 2026. The cannon is a new KNDS France system.

Rheinmetall signed a contract in December 2025 for the delivery of the weapon system and the electronic system, worth around €1.2 billion for the 84 first systems ordered by Germany and the UK.

• Qatar (12) • In September 2024, it was reported that Germany has approved the sale of the RCH 155 for Qatar in exchange for 12 PzH 2000, which were transferred to Ukraine. • Ukraine (54) • List of orders of Boxer RCH 155 ordered for the Ukrainian Ground Forces: • 18 howitzers ordered on 17 September 2022, announced as a purchase from Ukraine through a German aid fund at a cost of €216 million. • 18 howitzers ordered in February 2024, announced during the Munich Conference for Ukraine support, Germany added 18 additional RCH-155 to the planned support. • 18 howitzers ordered as per an announcement in June 2024 by KNDS. It was revealed that the total of RCH 155 for Ukraine was increased to a total of 54, which implies that 18 additional RCH-155 had been ordered. • In January 2025, Federal Minister of Defence Boris Pistorius symbolically consigned the first of a total of 54 RCH 155 to the Ukrainian ambassador to Germany, Oleksii Makeiev. The first six of these systems will initially remain in Germany and be used to train Ukrainian soldiers.
