To ask the Secretary of State for Defence, what the delivery date is for the Joint Crypt Key Programme.

The Joint Crypt Key Programme is delivering incrementally, and in 2022 delivered modernised End Crypto Devices to the Navy, with new sovereign communications modes and improved cryptographic interoperability standards for future crypt devices. It is presently upgrading the military cryptographic key management infrastructure. The programme will continue to sustain and modernise Defence’s high grade crypt key capabilities, with a clear programme of annual capability delivery milestones, and is expected to achieve Full Operating Capability in 2035.
