Italian company Sentiq integrates USVs, underwater sonars, ROVs and aerial drones for defence, security and commercial maritime applications
Sentiq Defence has commenced operations as an Italian integrator of autonomous and remotely operated maritime systems, bringing together technologies for defence, security and the blue economy.
The company works with international manufacturers to configure and integrate uncrewed surface vessels (USVs), underwater surveillance sonars, remotely operated vehicles (ROVs) and unmanned aerial systems (UAS), delivering mission-specific solutions supported from Italy.
What happens below the surface now matters to far more than navies. Energy operators, port authorities, telecommunication companies and coast guards all share the same problem: vast areas to watch, and not enough resources. Autonomous systems allow smaller teams to monitor wider areas, for longer and at lower risk and cost. Yet the market is fragmented: platforms, sensors and software from different suppliers, each with its own interfaces, support arrangements and export constraints.
Sentiq has been created to respond to that challenge. It adapts and integrates commercial-off-the-shelf (COTS) platforms and payloads to the customer’s mission and delivers a turnkey system, complete with training and through-life logistic support, all from a single Italian point of contact.
Sentiq’s offering covers three domains:
- Surface – the SQ family of modular USVs, configurable for hydrographic survey, environmental monitoring, offshore asset inspection and persistent surveillance, as well as defence missions such as mine countermeasures (MCM) and anti-submarine warfare (ASW).
- Underwater – sonars for detecting intruders, in fixed (SQ DDS) and portable (SQ PDDS) versions, and long-range (SQ UDS) to protect ports, naval bases, coastlines and critical infrastructure, supported by inspection-class ROVs.
- Air – tactical aerial drones that extend the surveillance reach of surface assets beyond the horizon.
Rooted in operational experience
Sentiq was founded by Antonio J. Belfiore, a retired Italian Navy Commander specialising in mine warfare. During 25 years of active service, he held operational and staff appointments at national and international level before moving into business development and sales roles with defence and subsea technology companies in Denmark and the United Kingdom.
“I spent most of my career at sea, in mine warfare, and later training the people who do this job,” says Antonio J. Belfiore, Founder and CEO of Sentiq Defence. “I learned that technology rarely fails on its own: what fails is integration. Sentiq was created to give anyone who works at sea – navies, coast guards, port and energy operators – full control of their domain: mission-focused solutions developed with our international partners, tailored here in Italy and supported by people who have done the job themselves. That, for us, is why we operate under the principle of ‘Command your space’.”
