USV Intelligent Command-and-Control Demonstration: South Korea test and trial record

Development and reported outcome

LIG Defense & Aerospace demonstrated intelligent command and control of heterogeneous unmanned surface vessels on May 27, 2026. Four live USVs were integrated with virtual assets, including Sea Sword-3, Sea Sword-5 and Sea Sword-S, and the event demonstrated cooperative autonomous maritime operations. The demonstration is a technology and operational-experimentation milestone, not a procurement award.[S1] [S2]

Program, platform and stakeholders

Programme or contract: USV Intelligent Command-and-Control Demonstration. Platform or product: Sea Sword-3; Sea Sword-5; Sea Sword-S. Recorded supplier, developer or relevant organization: LIG Defense & Aerospace (reported headquarters/country: South Korea). Recorded customer, operator or intended user: ROK defense / maritime-security stakeholders (reported headquarters/country: South Korea).[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: Anti-Surface / Strike; Anti-Submarine Warfare; Swarm / Collaborative Autonomy. Operating mode: Autonomous Surface Vessel (ASV).

Contract, value and shipment signals

Recorded quantity, delivery, demonstration or volume signal: 4 live USVs.[S1] [S2]

Source verification and interpretation limits

UXV Searcher master source-coverage note: Official LIG source confirms May 27 demonstration, four live Sea Sword USVs, coordinated swarm control, and both anti-surface and ASW scenarios. Official company source replaces the inaccessible Navy URL.

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 South Korea USV record for USV Intelligent Command-and-Control Demonstration 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 LIG Defense & Aerospace with ROK defense / maritime-security stakeholders for Sea Sword-3; Sea Sword-5; Sea Sword-S. 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 Anti-Surface / Strike; Anti-Submarine Warfare; Swarm / Collaborative Autonomy, the relevant next proof points are marine mission suitability, payload integration and measurable delivery or service outcomes. Monitor test result, qualification scope, operational acceptance and subsequent paid orders.[S1] [S2]

Quantitative evidence, calculations and limits

Quantity/scope signal: 4 live USVs. 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]
