Wave Glider

The Wave Glider is a wave- and solar-powered persistent autonomous surface vehicle made by Liquid Robotics, a wholly-owned Boeing subsidiary, recorded in the maritime form factor with the entity scoped to the Wave Glider product and Liquid Robotics as the maker. It converts wave motion into forward thrust through a submerged sub-float tethered to a surface float and uses solar power for its payloads, giving it theoretically indefinite endurance for ocean data collection, maritime domain awareness, and scientific work across defense, commercial, and science customers. The registry confirms its active state: Liquid Robotics remains a wholly-owned subsidiary of Boeing Defense, Space and Security, acquired on December 6, 2016 and relocated to Herndon, Virginia in 2022, and is neither divested nor wound down, correcting an earlier possibly-divested hypothesis, while the Wave Glider remains an active product with a 2025 Boeing and Liquid Robotics memorandum of understanding with India's Sagar Defence Engineering to co-produce Wave Gliders and a Pune manufacturing facility inaugurated in December 2025. Its editorial throughline is the persistent-presence-via-energy-harvesting archetype, the second example in the cohort alongside the Ocius Bluebottle, with both wind, wave, and solar indefinite-endurance vessels, the Wave Glider carrying the deeper Pacific operational history and Ocius the newer Royal Australian Navy program entry. Specific current customer rosters and fleet counts are not enumerated given limited Boeing-subsidiary disclosure, the India co-production is a memorandum and a facility rather than a delivered-units figure, and any aggregator-quoted deployment totals should be treated as company-sourced.
