UKDI autonomous sensing program: United Kingdom test and trial record

Development and reported outcome

ZeroUSV demonstrated Oceanus12 autonomously deploying two Oshen C-Star surface drones during UKDI-backed trials in Plymouth. The project combines Oceanus12, C-Star and MarineAI's autonomy software to demonstrate coordinated multi-platform surface operations for defense and security missions. The next phase is expected to scale the deployment to four C-Star vehicles, but that future step is not recorded as completed.[S1] [S2] [S3]

Program, platform and stakeholders

Programme or contract: UKDI autonomous sensing program. Platform or product: Oceanus12 + two C-Star ASVs + GuardianAI. Platform classification: Medium (Oceanus12 host: approx. 11.55 m). Recorded supplier, developer or relevant organization: ZeroUSV; Oshen; MarineAI (reported headquarters/country: United Kingdom). Recorded customer, operator or intended user: UK Defence Innovation (reported headquarters/country: United Kingdom).[S1] [S2] [S3]

Mission and technical scope

The following are classifications recorded in the source master, not additional claims of operational deployment: Mission/use-case classification: Swarm / Collaborative Autonomy; Underwater Sensing / Communications; Maritime ISR. Operating mode: Autonomous Surface Vessel (ASV).

Contract, value and shipment signals

Recorded quantity, delivery, demonstration or volume signal: 1 Oceanus12 host + 2 C-Star ASVs. Delivery schedule, procurement window or milestone status: Demonstration completed Aug 2026. Recorded contractual end: Ongoing program.[S1] [S2] [S3]

Source verification and interpretation limits

UXV Searcher master source-coverage note: Deep verified: ZeroUSV/Oshen/MarineAI demonstrated autonomous deployment of two C-Star surface drones from Oceanus12 in August under UKDI. Exact demonstration day is not disclosed; one Oceanus12 plus two C-Stars are confirmed.

Interpretation boundary: Testing, authorization and demonstrations should not be counted as confirmed purchases or fleet deliveries without a separate acceptance source.[S1] [S2] [S3]

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — validation / operational testing: The United Kingdom USV record for UKDI autonomous sensing program is best treated as a technical maturity signal. Testing, demonstration and certification-type activity can reduce integration uncertainty but is not equivalent to contracted fleet deployment.

Traceability for buyers: The dataset associates ZeroUSV; Oshen; MarineAI with UK Defence Innovation for Oceanus12 + two C-Star ASVs + GuardianAI. This supports stakeholder mapping; supply-chain tier, exclusivity and signed-customer relationships need the underlying source before firm classification.

Client-use interpretation: For intelligence users tracking Swarm / Collaborative Autonomy; Underwater Sensing / Communications; Maritime ISR, the relevant next proof points are underwater mission readiness, subsea navigation and operator acceptance. Monitor test result, qualification scope, operational acceptance and subsequent paid orders.[S1] [S2] [S3]

Quantitative evidence, calculations and limits

Quantity/scope signal: 1 Oceanus12 host + 2 C-Star ASVs. Counting rule: Trial/deployment context; not necessarily procurement or paid fleet additions. Delivery/timing evidence: Demonstration completed Aug 2026. Scheduling language is not independently proof of completion or acceptance.

Trial participation and travelled distance describe testing activity, not sales volumes.[S1] [S2] [S3]
