Company Overview

Subsea Tech is a French marine-robotics manufacturer founded in December 2005 and based at 167, Plage de l'Estaque in Marseille, on France's Mediterranean coast. The company designs, builds and sells or rents intervention and instrumentation systems for underwater and surface marine applications, serving oil & gas, naval/defence, scientific-research and environmental customers. It holds certification as a Research Organisation from the French Ministry of Higher Education and Research and participates in regional research clusters covering maritime technology and visual-imaging systems. The company is a small enterprise, with headcount estimated in the range of roughly 11 to 50 employees.

Its mini-ROV line includes the Guardian, an observation-class ROV rated to 150 m depth with a four-horizontal-thruster configuration, capable of tethered excursions up to 500 m and fitted with an ancillary mounting plug for sonars, gauges or manipulators. Its AspiROV is a combined inspection-and-cleaning ROV rated to 100 m depth, weighing 12 kg in air (6 kg neutral in water, ballast-adjustable) with dimensions of 66 x 43 x 53 cm; it pairs a 35 m suction hose with a 30 m3/h centrifugal gasoline pump to clean the floor of drinking-water, industrial-water and fire-suppression storage tanks while performing simultaneous visual inspection, without draining the tank. On the surface side, its CAT-Surveyor is an unmanned surface vehicle measuring 3 m in length with a 1.6 m beam, weighing 270 kg dry, reaching 5 knots and running roughly 12 hours on twin Li-ion battery packs; its open architecture accepts hydrographic and environmental survey sensor payloads.

Subsea Tech has supplied customers including offshore energy operators and defence users, and has been active in EU-funded marine-robotics research initiatives such as the SEACLEAR ocean-debris-collection project. Its product range positions the company as a specialist builder of compact, portable ROV and USV platforms rather than large work-class subsea systems, and it maintains a UK representation agreement with Shackleton Offshore to support customers in that market.

FUTURE WARFARE | Sea - Autonomous Surface Vessels & Unmanned Underwater Vehicles — The Hybrid Fleet Takes Shape

FUTURE WARFARE | Sea - Autonomous Surface Vessels & Unmanned Underwater Vehicles — The Hybrid Fleet Takes Shape

Ukraine’s ‘Sub Sea Baby’ autonomous torpedo struck a Russian Kilo-class submarine inside Novorossiysk harbour in December 2025 — the first confirmed underwater drone attack on a submarine in history. The U.S. Navy is requesting $5.3 billion for unmanned maritime systems in FY2026, a 70 percent year-on-year increase. Saronic Technologies went from prototype to $392 million production contract in under 12 months. And DARPA’s Manta Ray XL-UUV completed full-scale sea trials. This article maps the maritime autonomous systems revolution — from Ukraine’s improvised Black Sea fleet to the Pentagon’s hybrid manned–unmanned force of the 2030s, and from Saronic’s Franklin, Louisiana shipyard to Boeing’s 85-tonne robot submarine.
