UMEX 2026 - LIG D&A Sea Sword-X / Sea Sword-II Presentation: South Korea exhibition or demonstration

Development and reported outcome

LIG Defense & Aerospace presented the Sea Sword-X modular unmanned surface vessel at UMEX 2026 in Abu Dhabi from January 20 to 22. The platform was presented for surveillance, reconnaissance, combat and maritime-security missions, while independent government technical material identifies anti-ship weapon options. The event is a South Korea-origin export-market presentation and does not represent a foreign procurement award.[S1] [S2] [S3]

Program, platform and stakeholders

Programme or contract: UMEX 2026 - LIG D&A Sea Sword-X / Sea Sword-II Presentation. Platform or product: Sea Sword-X modular USV concept. Platform classification: Large (30 m). Recorded supplier, developer or relevant organization: LIG Defense & Aerospace (reported headquarters/country: South Korea). Recorded customer, operator or intended user: International defense and maritime customers; no named procurement customer (reported headquarters/country: United Arab Emirates / 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: Surveillance / Reconnaissance; Anti-Surface / Strike; Combat; Counter-Drone / Maritime Security. Operating mode: Autonomous Surface Vessel (ASV).

Contract, value and shipment signals

The master does not contain a dependable disclosed contract amount, shipment quantity or delivery schedule for this development. These should not be assumed to be zero.[S1] [S2] [S3]

Source verification and interpretation limits

UXV Searcher master source-coverage note: LIG validates the UMEX 2026 Sea Sword-X presentation. French Ministry of Armed Forces technical coverage identifies Sea Sword-X as a 30 m unmanned surface vessel with anti-ship weapon options. It is Large under the user's >24 m rule and supports ISR plus antiship/combat missions.

Interpretation boundary: A conference presentation or exhibition display is not, by itself, evidence of a sale, production contract or fleet entry.[S1] [S2] [S3]

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — industry event / public visibility: The South Korea USV record for UMEX 2026 - LIG D&A Sea Sword-X / Sea Sword-II Presentation is best treated as a ecosystem visibility signal. A display, award or conference appearance is evidence of visibility, not inherently of orders, production or deployment.

Traceability for buyers: The dataset associates LIG Defense & Aerospace with International defense and maritime customers; no named procurement customer for Sea Sword-X modular USV concept. 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 Surveillance / Reconnaissance; Anti-Surface / Strike; Combat; Counter-Drone /…, the relevant next proof points are mission validation, safety standards and production commitments. Track named customer or programme commitments and independently confirmed commercial follow-on announcements.[S1] [S2] [S3]

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] [S3]
