Overview

Ocius has partnered with US-based company ThayerMahan to deliver Bluebottle uncrewed surface vessels in support of advanced anti-submarine warfare (ASW) and intelligence, surveillance and reconnaissance operations for the United States Navy and United States Coast Guard.

ThayerMahan undertook a comprehensive evaluation to identify the most effective ASW platform available globally. Following extensive trials, ThayerMahan selected the Bluebottle USV for its combination of quite acoustic performance, superior ability to remain on station and cost-effectiveness.

Participation in US Navy exercises focused on submarine detection have demonstrated the platform’s endurance and resilience in harsh environments.

ThayerMahan has rigorously tested Bluebottle USVs in demanding real-world conditions, including:

  1. Long-range transits along the US East Coast, from Florida to Connecticut

  2. Operations through two hurricanes

Delivering equivalent coverage with a traditional patrol vessel would typically require continuous operations and consume thousands of litres of diesel, meaning the deployment of two Bluebottles avoided an estimated 120–160 tonnes of CO₂ emissions over a month.
