令和8年度～令和10年度「通信機器借上／水中無人機OZZ-100用イリジウム衛星通信回線（閉域網）」: Japan procurement notice

Development and reported outcome

On August 20, 2026, JMSDF Supply Headquarters issued a distinct FY2026-FY2028 solicitation for closed-network Iridium communications supporting the OZZ-100 UUV. The requirement covers SBD/Certus services and a closed-network configuration, making it a later and separate communications-support requirement from the April OZZ-100 Iridium solicitation. Applications opened August 26 and remained open through September 9, so the procurement was active on August 31.[S1]

Program, platform and stakeholders

Programme or contract: 令和8年度～令和10年度「通信機器借上／水中無人機OZZ-100用イリジウム衛星通信回線（閉域網）」. Platform or product: OZZ-100 closed-network Iridium communications. Platform classification: Autonomous Operated Vehicle. Recorded supplier, developer or relevant organization: JMSDF Supply Headquarters (reported headquarters/country: Japan). Recorded customer, operator or intended user: JMSDF (reported headquarters/country: Japan).[S1]

Mission and technical scope

The following are classifications recorded in the source master, not additional claims of operational deployment: Mission/use-case classification: Communications / secure C2.

Contract, value and shipment signals

Original-currency label: JPY. Recorded quantity, delivery, demonstration or volume signal: Communications-service package. Delivery schedule, procurement window or milestone status: Status as of Aug. 31, 2026: Application Period Open; bid/application deadline: Sept. 9, 2026. Recorded contractual end: Sept. 9, 2026.[S1]

Source verification and interpretation limits

UXV Searcher master source-coverage note: This is distinct from the April 22 OZZ-100 communications solicitation because it covers a later closed-network configuration and FY2026-FY2028 support period.

Interpretation boundary: The tender, notice or request stage does not by itself prove a signed contract, selected supplier, or physical delivery.[S1]

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — procurement requirement / tender: The Japan UUV record for 令和8年度～令和10年度「通信機器借上／水中無人機OZZ-100用イリジウム衛星通信回線（閉域網）」 is best treated as a procurement pipeline signal. A published requirement can indicate addressable demand, but it is not an award, supplier revenue, shipment, or fleet increase.

Traceability for buyers: The dataset associates JMSDF Supply Headquarters with JMSDF for OZZ-100 closed-network Iridium communications. 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 Communications / secure C2, the relevant next proof points are underwater endurance, navigation, payload integration and operator acceptance. Track the award notice, signed value and accepted delivery quantities before upgrading this demand signal.[S1]

Quantitative evidence, calculations and limits

Quantity/scope signal: Communications-service package. Counting rule: Requested scope; not a delivery or award total. Delivery/timing evidence: Status as of Aug. 31, 2026: Application Period Open; bid/application deadline: Sept. 9, 2026. Scheduling language is not independently proof of completion or acceptance.

Quantified requirements are potential procurement scope, not realised hardware orders or sales.[S1]
