SeaSEC 2026 Data2Sea: Germany test and trial record — Apr-26

Development and reported outcome

From April 13-24, 2026, GREYSHARK Foxtrot continued its prototype test campaign during the German Navy-linked SeaSEC Data2Sea experimentation period. The vehicle was evaluated in an operational maritime environment focused on seabed security, critical-underwater-infrastructure surveillance, and integrated data collection. This is a separate lifecycle stage from Foxtrot's first entry into the water and represents prototype maturation rather than German Navy acceptance or deployment.[S1] [S2]

Program, platform and stakeholders

Programme or contract: SeaSEC 2026 Data2Sea. Platform or product: GREYSHARK Foxtrot. Platform classification: Autonomous Operated Vehicle. Recorded supplier, developer or relevant organization: EUROATLAS GmbH; EvoLogics GmbH (reported headquarters/country: Germany). Recorded customer, operator or intended user: Deutsche Marine / NNCC SeaSEC (reported headquarters/country: Germany).[S1] [S2]

Mission and technical scope

The following are classifications recorded in the source master, not additional claims of operational deployment: Mission/use-case classification: Critical Underwater Infrastructure Protection; Underwater ISR / Surveillance; Technology Demonstration / Testbed.

Contract, value and shipment signals

Delivery schedule, procurement window or milestone status: SeaSEC ran April 13-24, 2026.[S1] [S2]

Source verification and interpretation limits

UXV Searcher master source-coverage note: SeaSEC participation is a distinct prototype-test stage after the first in-water milestone. No military acceptance or procurement is inferred.

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

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — validation / operational testing: The Germany UUV record for SeaSEC 2026 Data2Sea 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 EUROATLAS GmbH; EvoLogics GmbH with Deutsche Marine / NNCC SeaSEC for GREYSHARK Foxtrot. 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 Critical Underwater Infrastructure Protection; Underwater ISR / Surveillance;…, 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]

Quantitative evidence, calculations and limits

Quantification limit: No sufficiently attributed contract value or physical platform count is disclosed for this record. UXV Searcher leaves these fields unavailable rather than treating non-disclosure as zero or applying an unsupported market average.

The useful output is a qualitative stage and stakeholder signal, not a numerical forecast.[S1] [S2]
