The same Portsmouth office issued a second notice on 5 August: a £10m multi-role uncrewed surface vessel testbed for the Defence Chief Technology Officer, running from March 2027 to March 2030.

Key takeaway

The Royal Navy has flagged £10m for a dedicated uncrewed vessel testbed running to March 2030.

Navy Commercial issued a second notice on 5 August, 074351-2026, for a £10m multi-role uncrewed surface vessel testbed sponsored by the Defence Chief Technology Officer (DCTO), the Ministry of Defence office funding the work⁠¹. The contract period runs from 1 March 2027 to 31 March 2030. A pipeline notice of this kind flags intended spending to the market rather than opening a competition.

The testbed must run in three configurations: controlled from shore, integrated with a mothership, and distributed alongside other uncrewed vessels⁠². The Royal Navy has already run the middle configuration in a real deployment. The Royal Fleet Auxiliary support ship RFA Lyme Bay embarked France's Sirius minehunting drone at Toulon in early June and operated it from the deck. What that arrangement lacks is a British hull dedicated to trying things that might not work.

A testbed exists so that failures happen on a vessel nobody has bet a programme on. The notice went out the same day as the Platform Authority consultation, from the same office, which puts the experimental hull and the certifier on the same procurement clock.

Deep Analysis

In plain English

The same Royal Navy office that wants to build a Platform Authority is also spending £10m on a test boat. This one is not for fighting or mine-hunting; it is for trying out different ways of controlling uncrewed boats, from a shore base, from a mothership at sea, or spread across a network with no single controller. The contract runs from March 2027 to March 2030, so the Navy is giving itself three years to work out which control method actually works best before betting the rest of the fleet on one.

Deep Analysis

Root Causes

Notice 074351-2026 asks a single testbed to run three different control architectures, shore-controlled, mothership-integrated and distributed, rather than committing to one.

That is a hedge: the Defence Chief Technology Officer's office does not yet know which control model the rest of the fleet should standardise on, and a £10m testbed is cheap enough to buy time on that decision without committing the wider Mine Hunting Capability or Common Combat Vessel programmes to an architecture that turns out wrong.

The testbed's 1 March 2027 start, nearly seven months after the notice, also reflects the same governance gap notice 074032-2026 was trying to close : a testbed contracted before the Platform Authority exists will be assessed against whatever ad hoc standard the Defence CTO's office applies today, not whatever standard the Platform Authority eventually sets.

What could happen next?

Meaning
The three-configuration remit signals the Navy has not settled on a single control architecture for uncrewed surface vessels, which the testbed exists to help decide.

Different Perspectives

DNV and Fassmer

Signed a memorandum at SMM in Hamburg, announced on 10 September, to seek an approval in principle for autonomous naval vessels. DNV's Rasmus Stute said autonomy is "becoming one of the key pillars in defence".

Belgian Ministry of Defence

Awarded Exail Robotics Belgium €9.87m on 14 September, without competition, for three TRIDENT systems carrying the K-STER C mine-disposal vehicle for Ukraine. It had tendered separately in July for twelve tethered ROVs, not yet bought.

IRGC Navy (Iran)

IRGC spokesman Hossein Mohebbi said the IRGC Navy seized a US Kingfish mine-hunting vehicle in the Strait of Hormuz on 27 September, valuing it at several million dollars. US Central Command calls the claim "clearly desperate"; no verified imagery exists.

UK Defence Intelligence and Kraken

Defence Intelligence said the 12 September clash "almost certainly marks the first time" Russian and Ukrainian USVs engaged directly. Kraken meanwhile trialled an unarmed Saab radar picket boat on 5 and 6 October.

Ukrainian forces and ARX Robotics

A Ukrainian Sargan-3000 destroyed a Russian robot boat on 12 September, and the first ARX GEREON ground robots reached Ukraine on 29 September. The Sargan-3000 carries a mounted gun.

Indian Register of Shipping

Certified Accurate Industrial Controls' ISACA collision-avoidance software to IMO standards after five audited milestones and 2,500 hours of trials. The firm plans to use it converting six Indian Navy patrol boats.
