H-USVs offer long endurance of up to 70 days at 5 knots, with a sprint speed of 20 knots. Operated as a swarm they provide enhanced geographical coverage, acting as both a deterrent to those committing illegal activities, as well as providing a means of intercepting vessels and recording hi-resolution footage for prosecution.

In addition to security patrols, H-USVs also offer an environmental and safety management solution. They can be operated on multi-mission deployments, collecting scientific data as well as supplementing existing search and rescue apparatus. 

Example use case


Deployment of 14 AO Guard vessels as a swarm to provide a 350nm deterrent and visual perimeter along the English Channel to support counter narcotics and human trafficking operations, and provide search and rescue for migrant crossings.

The AO Guard swarm can identify threats and anomalies – including vessels that are too small for radar, and those operating without AIS. The AO Guard sends an alert, and the operator notifies Border Control, the MCA, Royal Navy and deploys the most optimally positioned vessels to track and intercept – the rest of the fleet reforms a perimeter to detect further incursions.


The lead AO Guard vessel sails to intercept the target at an interception speed of 20 knots, whilst trying to establish comms via VHF. At a range of 1-2nm the AO Guard uses the LRAD system to warn the vessel that it is entering UK waters.


If the target vessel persists, the AO Guard has the capability to deploy non-lethal deterrents.


The AO Guard continues to track the incoming vessel maintaining a stand-off distance, relaying its GPS co-ordinates to the authorities, whilst remaining in proximity to offer search and rescue support in the event the suspect vessel runs into trouble.

The AO Guard maintains a line of site and continues to transmit low bandwidth video, focussed on identifying the target vessel operator while crewed vessels move to site. The AO Guard continues to capture secure encrypted HD video suitable for prosecution.
