Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what is the total cost of the RCH 155m artillery system to the MoD in terms of a) acquisition cost and b) through-life cost.

In line with the Integrated Procurement Model, the UK’s Remote Controlled Howitzer 155 (RCH155) programme will deliver a Minimum Deployable Capability (MDC) within this decade. This capability is defined as a Royal Artillery Battery equipped with RCH155 platforms, having completed the necessary specialist training. As a minimum, the system will have an appropriate peacetime safety case to enable training on UK ranges, preparing the sub-unit for potential operational deployment.

The current acquisition cost for the RCH155 programme is estimated to exceed £1 billion. This figure comprises the £52 million Early Capability Demonstrator contract awarded in December 2025 in addition to the £53 million Long Lead Item contract let in March 2025, and the UK’s series production contract announced on 13 May 2026. The estimated Whole Life Cost of procuring and supporting a fleet of 72 RCH155 systems is expected to exceed £3 billion over the currently projected 25-year service life.
