GREYSHARK Bravo SeaSEC operational trials: Germany test and trial record
From April 13-24, 2026, the battery-powered GREYSHARK Bravo participated in SeaSEC 2026 during the final phase of its operational-trials program. The campaign provided a German Navy-linked environment for evaluating the more mature Bravo architecture in seabed-security, infrastructure-protection, mine-countermeasure, and related underwater-defence missions.

Development and reported outcome
From April 13-24, 2026, the battery-powered GREYSHARK Bravo participated in SeaSEC 2026 during the final phase of its operational-trials program. The campaign provided a German Navy-linked environment for evaluating the more mature Bravo architecture in seabed-security, infrastructure-protection, mine-countermeasure, and related underwater-defence missions. The event does not establish serial-production commencement, customer acceptance, or vehicle delivery.[S1] [S2]
Program, platform and stakeholders
Programme or contract: GREYSHARK Bravo SeaSEC operational trials. Platform or product: GREYSHARK Bravo. 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; Mine Countermeasures; Anti-Submarine Warfare; Underwater ISR / Surveillance.
Contract, value and shipment signals
Delivery schedule, procurement window or milestone status: SeaSEC followed by further planned trials and REPMUS.[S1] [S2]
Source verification and interpretation limits
UXV Searcher master source-coverage note: Lifecycle reporting explicitly distinguishes Bravo from Foxtrot and places Bravo in the final phases of operational trials during SeaSEC.
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 GREYSHARK Bravo SeaSEC operational trials 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 Bravo. 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; Mine Countermeasures; Anti-Submarine…, the relevant next proof points are mine-countermeasures requirements, autonomy integration and acceptance milestones. 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]
