SeaSEC Data2Sea 2026: Denmark test and trial record — Apr-26 — ProZero 8M Sentinel ISR USV

Development and reported outcome

Tuco Marine's ProZero Sentinel USV participated in live SeaSEC Data2Sea experimentation with CUBEDIN integration. CUBEDIN combined vessel navigation, position, speed, camera and connectivity information within a unified architecture supporting remote maritime operations. The event validates Denmark-origin USV and C2 technology in multinational military experimentation but does not establish a foreign procurement.[S1] [S2] [S3]

Program, platform and stakeholders

Programme or contract: SeaSEC Data2Sea 2026. Platform or product: ProZero 8M Sentinel ISR USV. Platform classification: Medium (8.2 m).

Recorded customer, operator or intended user: German Navy-led SeaSEC / multinational participants (reported headquarters/country: Germany / Multinational).[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: Maritime ISR / MDA; System-of-Systems Integration. Operating mode: Autonomous Surface Vessel (ASV).

Contract, value and shipment signals

Recorded quantity, delivery, demonstration or volume signal: 1.[S1] [S2] [S3]

Source verification and interpretation limits

UXV Searcher master source-coverage note: CUBEDIN's case study confirms SeaSEC/Data2Sea remote-USV integration; Tuco's official product page identifies the ProZero 8M Sentinel ISR USV and 8.2 m length.

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 Denmark USV record for SeaSEC Data2Sea 2026 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 Tuco Marine / CUBEDIN with German Navy-led SeaSEC / multinational participants for ProZero 8M Sentinel ISR USV. 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 Maritime ISR / MDA; System-of-Systems Integration, the relevant next proof points are maritime awareness persistence, sensors and communications interoperability. Monitor test result, qualification scope, operational acceptance and subsequent paid orders.[S1] [S2] [S3]

Quantitative evidence, calculations and limits

Quantity/scope signal: 1. Counting rule: Trial/deployment context; not necessarily procurement or paid fleet additions.

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