What Seadar Blue does
Seadar Technologies (operating under the brand Seadar Blue / SEADAR™) is a private US-based subsea sensing company that develops Ultra-Low Frequency (ULF) radio-wave radar systems for detecting, geolocating, mapping, and tracking metallic materials and electronic signatures underwater. The company markets two core products: SEADAR™ Survey, a vessel-towed multi-band metal-detection radar used for UXO clearing, offshore wind and oil-and-gas site survey, ocean mining, subsea cable mapping, and salvage; and SEADAR™ Shield, a multi-static underwater intruder detection radar providing jam-resistant, real-time perimeter monitoring for harbors and sensitive maritime assets. Both systems leverage saltwater EM propagation to penetrate non-metallic media and discriminate manmade conductive objects from natural geology, with the multi-static Shield architecture explicitly designed to detect stealth craft using anechoic tiles or stealth propellers.
The commercial model is hardware-centric (sale of integrated radar systems) augmented by professional survey and monitoring services for specialized defense and commercial applications. Pricing is undisclosed and contact-based, consistent with enterprise defense procurement. Go-to-market is direct enterprise sales into defense ministries, coast guards, offshore energy operators, and operators of critical national infrastructure across the NATO Alliance and US Allies. The company self-describes as a team of 1-10 entrepreneurs, scientists, and engineers and holds a registered SEADAR™ trademark.
Revenue, ownership, management team, and closed funding history are not disclosed in the available material. The most recent capital event is a $0 PortXL accelerator participation dated 2024-09-13, indicative of ecosystem engagement rather than dilutive equity capital. The company explicitly targets eight market sectors—UXO clearing, renewables, offshore oil and gas, critical national infrastructure, telecommunications, ocean mining, search and recovery, and archaeology—which signals deliberate broad-TAM positioning but does not constitute evidence of commercial scale.

Seadar Blue product offering
Product offeringCore offering
Seadar Blue designs and manufactures underwater radar systems based on Ultra-Low Frequency radio wave technology for detecting and monitoring activity beneath the water surface. Its commercial offerings consist of two hardware product lines: SEADAR Survey, used for hydrographic and oceanographic survey work, and SEADAR Shield, used for subsea security and intrusion detection around ports, harbors, and critical infrastructure.
Product overview
SEADAR™ Technologies offers two distinct subsea radar products: SEADAR™ Survey is a vessel-towed metal detection radar for underwater detection, geolocation, mapping, and tracking of metallic objects and electronic signatures; SEADAR™ Shield is an underwater intruder detection radar providing continuous real-time monitoring and security surveillance for maritime infrastructure. Both products leverage Ultra-Low Frequency (ULF) radio waves that penetrate saltwater and non-metallic materials, with the Survey system using multi-band simultaneous frequencies for 3D target localization and the Shield system using multi-static radar with multiple transmit/receive antenna nodes for wide-area jam-resistant detection coverage.
