Bluebottle at Australia

Ocius Technology (Sydney, New South Wales; founder and chief executive Robert Dane, evolved from his earlier Solar Sailor venture and renamed Ocius in 2014) makes the Bluebottle, a wind-, solar-, and wave-powered persistent autonomous surface vessel, recorded in the maritime form factor. The Bluebottle harvests energy three ways, through a patented hard solar sail combining wind and solar, crystalline-silicon solar panels, and rudder-mounted wave oscillators for passive propulsion, giving it average missions of about 75 days and a longest deployment of 184 days.

The registry records it at commercial maturity: a A$176 million, 40-vessel, five-year Royal Australian Navy program of record announced on March 11, 2026 expands the RAN fleet from 15 to 55 vessels with deliveries from early 2026, and Ocius has operated Bluebottles around the clock from HMAS Coonawarra in Darwin for the border-security Operation Resolute since July 1, 2024 with 15 vessels already delivered. Its editorial throughline is the persistent-presence-via-energy-harvesting hardware archetype, with theoretically indefinite endurance and vessels sold outright to the RAN and US primes, distinct from Saildrone's captive data-as-a-service and Saronic's US new-defense procurement.

Several cap-flags and corrections apply: the A$176 million figure's ceiling-versus-obligated split is undisclosed in all sources including the primary government release, so it is recorded as a government-reported headline value; the US Navy relationship is indirect through the prime ThayerMahan, which bought two Bluebottles for A$2.4 million and ran the US Navy anti-submarine-warfare demonstrations rather than a direct US Navy procurement; a NOAA customer relationship could not be verified and is dropped; and Ocius's funding is not verifiable with no institutional round, while its founding year and hull length conflict across sources.
