Authority: Ministry of Defence (Central government)
What is being bought
Published requirement descriptionThis Pre-Market Engagement seeks to identify suppliers whose Autonomous Underwater Vehicles (AUVs) can meet the MOD’s Minimum Viable Requirement (MVR) and to understand which platforms may support future development. This is not an evaluative exercise and nothing in this activity will limit the opportunity to engage in any follow-on ITT.
The Royal Navy’s Diving and Threat Exploitation Group (DTXG) delivers a range of operational outputs, including protection of critical undersea infrastructure in home waters and deployed support to maritime operations. Inherent in these tasks is a requirement to survey and understand the underwater battlespace; tracking undersea cables and pipelines, charting beaches, ports and maritime infrastructure, and plotting potential obstructions or objects. These operations will frequently need to be conducted from small boats by light-role teams at significant range from a host platform. The possibility for sub-surface deployment and recovery is desirable.
To meet this requirement, DTXG is exploring a portable, single operator deployable AUV system for environmental data gathering, survey operations, and exploratory autonomous missions in coastal/offshore waters. The rapid procurement of this system will allow the development of the capability alongside the Original Equipment Manufacturer; the key user requirements are below in the following format:
Requirement Area - Requirement Statement - Minimum Requirement
- Depth Performance - Operate effectively in coastal and shelf-sea environments requiring mid-depth capability - equal to or greater than 300 m depth rating
- Portability - Deployable and recoverable by a single operator without mechanical lifting assistance - Single-person portable & recoverable; no mechanical/specialist Launch And Recovery System
- Endurance - Support meaningful survey/data-gathering missions - multi-hour mission capability
- Navigation & Comms - Operate safely and autonomously using standard technologies - Autonomous nav/comms suite suitable for AUV operations
- Modularity/Deployment Pathway (Desirable) - Provide scope for future payloads, upgrages or development - Modular payload or development pathway (desirable)

How Ministry of Defence buys Warships (CPV 3551), and who usually turns up
Ministry of Defence’s own published record, next to the published market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Warships (CPV 3551) →
How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Here, local means the winner is registered in the region where that contract was delivered.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered in Greater London.
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced within 50 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
Both shares are minimums: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.
Past bids do not predict this tender.

How did awards compare with estimates?
i
Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
Past prices are a guide, not a bid price.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
