Summary of the contracting process

The Submarine Delivery Agency, a central government authority within the UK Ministry of Defence, has planned a procurement process under the title "A-Class Platform Complex Systems - Batch 1 PMS and ICS" located in Bristol, UK. This procurement involves the provision of in-service support for Internal Communication Systems (ICS) and Astute Class Platform Complex Systems Batch 1 Platform Management System (PMS), including technical support and spares. The process is valued at approximately £51,000,000 excluding VAT and spans a period from 1st March 2026 to approximately 2033. The procurement method is Direct Award due to technical compatibility requisites, with milestone signatures anticipated by 19th October 2026. The procurement status is presently in the planning stage, offering a unique opportunity to businesses with expertise in defence and security services.

This procurement provides substantial growth opportunities for businesses specialising in technical support and post-design services, particularly those with experience in defence systems. As L3Harris Mapps Limited, the Original Equipment Manufacturer (OEM) and Design Authority for the ICS and A-Class systems, holds proprietary information essential to the contract, businesses with capability in building partnerships or subcontracts with L3Harris may find valuable prospects. Companies operating at a large scale with technical prowess in maritime and communication systems will be well-suited to engage in collaborative opportunities stemming from this procurement. This contract is pivotal due to its role in supporting critical safety and operational functions for submarine delivery, thereby offering involvement in paramount national security projects.
