Navy Commercial, the Royal Navy procurement office at Whale Island in Portsmouth, published preliminary market engagement notice 074032-2026 on 5 August, asking industry how to stand up a Platform Authority for maritime uncrewed systems 1. A preliminary market engagement is a pre-tender consultation, in which the Ministry of Defence asks suppliers what is possible before any contract is written. The scope covers governance, engineering, certification support and through-life assurance. Responses close on 19 August, the tender itself is estimated for 20 August, and a down-selected group attends industry days in Portsmouth on 1 and 2 September 2.
A Platform Authority is the office that certifies an uncrewed vessel as safe to operate. It is a harder job than certifying a crewed one, because no captain is aboard to override the automation when something goes wrong. The notice states that the authority's own post must be held by a crown servant, with supporting organisations seconding workforce and expertise into it 3. Small firms and voluntary-sector suppliers are named as suitable bidders, which matters because most of Britain's uncrewed-vessel builders are small firms.
The seaworthiness half of this went up fast. The International Maritime Organization (IMO), the United Nations agency for shipping standards, adopted the first Maritime Autonomous Surface Ships (MASS) Code in May , and the code entered force on 1 July . The Maritime and Coastguard Agency (MCA) published its Maritime Innovation Hub approval route on 3 June . Both answer whether the boat can be trusted at sea. Neither asks who made the parts fitted inside it.
The timing runs in Britain's favour on one reading. This notice went out four days before The Telegraph published, and the Marine Accident Investigation Branch (MAIB) refreshed its investigations register on 6 August, and both of the uncrewed-vessel cases on it date from September 2025 4. Assurance is working at the speed of a market engagement notice, and the boats have been in special forces hands since the spring.
