SABUVIS II: Development milestone in Poland — 07 Feb 2026

Development and reported outcome

The European Defence Agency concluded SABUVIS II in early February 2026 after four years of work led by Poland. Although primarily focused on underwater swarms, the project explicitly developed mixed swarms integrating underwater and autonomous surface vehicles and validated common C2 and interoperability approaches. The EUR 3.7 million is the total multinational project budget, not a Poland-only USV procurement value.[S1] [S2]

Program, platform and stakeholders

Programme or contract: SABUVIS II. Platform or product: Mixed swarm integrating autonomous underwater and autonomous surface vehicles. Recorded supplier, developer or relevant organization: Poland-led EDA consortium (reported headquarters/country: Poland / European Union). Recorded customer, operator or intended user: Participating European defense ministries / navies (reported headquarters/country: European Union).[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: Swarm / Collaborative Autonomy; Maritime ISR / MDA. Operating mode: Autonomous Surface Vessel (ASV) element within mixed USV/UUV swarm.

Contract, value and shipment signals

Original reported amount or scope: EUR 3.7 million total multinational EDA project budget. Original-currency label: EUR. Recorded contractual start: 8-Feb-22. Recorded contractual end: 7-Feb-26. Recorded contractual duration: 4 years.[S1] [S2]

Source verification and interpretation limits

UXV Searcher master source-coverage note: EDA confirms the Poland-led SABUVIS II project concluded in early February with EUR 3.7 million budget; Łukasiewicz-PIAP gives the Feb. 8, 2022-Feb. 7, 2026 project period. USVs and UUVs are kept distinct within the mixed swarm.

Interpretation boundary: A development milestone does not by itself establish completion, acceptance or fleet induction.[S1] [S2]

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — product or engineering development: The Poland USV record for SABUVIS II is best treated as a technical progression signal. The record documents a capability step or integration scope, not proof of mass production or repeatable sales.

Traceability for buyers: The dataset associates Poland-led EDA consortium with Participating European defense ministries / navies for Mixed swarm integrating autonomous underwater and autonomous surface vehicles. 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 Swarm / Collaborative Autonomy; Maritime ISR / MDA, the relevant next proof points are maritime awareness persistence, sensors and communications interoperability. Watch for successful acceptance testing, commercial availability, customer commitments and quantified deliveries.[S1] [S2]

Quantitative evidence, calculations and limits

Financial signal (master transcription): EUR 3.7 million total multinational EDA project budget. Classification: Tender estimate, ceiling or budget, not necessarily an awarded or paid amount. Reproducible calculations: Recorded start-to-end calendar interval: 1,460 days ((2026-02-07) - (2022-02-08) = 1460 elapsed calendar days). Refer to the calculation cards for assumptions and limitations.

Keep reported, derived and prospective quantities separate; do not convert activity into installed-base counts without a shipment or acceptance source.[S1] [S2]
