Company Overview

Sonardyne is a British underwater-technology company founded in 1971 by John Partridge, whose company name combines sonar and dyne, a unit of force. Headquartered at Blackbushe Business Park in Yateley, Hampshire, England - a purpose-built facility the company calls Ocean House, opened in 1996 - Sonardyne designs and manufactures precision instruments and delivers custom engineering services for tracking, monitoring, imaging, surveying and navigating in subsea environments. The company has more than 50 years of operating history and states it has been carbon neutral since 2023. As of 2026, Sonardyne operates as part of Kraken Robotics following an acquisition that combined the two companies' subsea technology portfolios.

Sonardyne's product families include the SPRINT-Nav range of subsea navigation systems, which combine inertial and Doppler sensing for underwater vehicle guidance; the Ranger 2 family of ultra-short baseline (USBL) acoustic positioning systems; the RT 6 family of acoustic release transponders used in subsea moorings; the Origin family of acoustic Doppler current profilers for ocean monitoring; and the BlueComm 200 UV underwater optical communication system. The company also provides equipment hire, custom engineering and training services to support subsea operations.

Target sectors include oil and gas, offshore renewable energy, ocean science and research, defence and maritime security, and carbon capture and storage, reflecting Sonardyne's role as an instrumentation and positioning supplier across both commercial offshore energy and scientific and defence subsea markets. In July 2026 the company took part in the Smart Sound Connect demonstration event, showcasing marine autonomy and underwater positioning capabilities alongside other participants in real-world sea trials.

Sonardyne maintains an active public presence across LinkedIn, X, Facebook and YouTube under its own brand, and continues to operate its original support and eShop channels for existing customers even as it integrates with Kraken Robotics' broader marine technology group. Specific current headcount and direct phone/email contact details were not published on the company's own site as of this record.
