Maritime Arresting Technologies is pleased to announce that the company’s Stingray Unmanned Underwater Vessel (UUV) Interceptor Net has been nominated to compete in the 2017 ‘ASTORS’ Homeland Security Awards Program.
Maritime Arresting Technologies was recognized with the Top Award in the 2016 ‘ASTORS’ Homeland Security Awards Program, Winning the Platinum Award for Best Maritime Perimeter Protection System.
Maritime Arresting Technologies, has been working with the U.S. Navy under a cooperative research and development agreement (CRADA) to conceive and develop a system to successfully intercept underwater threats such as autonomous vessels and divers.
UUVs are now considered a threat to high value assets on or beside the water.
The Stingray UUV Interceptor System consists of a net that is rapidly deployable in front of a hostile UUV or other underwater threat (swimmer, self-propelled mine, etc.)
- The net is stored in a composite box that firmly attaches to the transom of a patrol boat.
- When the lid is opened it forms a chute that keeps the net clear of the drive units of the patrol boat and ensures that the net deploys without snags or twists.
- The net provides protection across the entire water column, extending from the water surface to the seabed.
- Constructed from mono-filament nylon it is practically invisible and therefore hard to avoid.
- The net encapsulates the oncoming UUV, snagging on all and any projections.
- Once captured the UUV can be towed away to be dealt with far from the target.
Test Results
100% success result in trials at NUWC Newport when deployed into the path of a hostile UUV.
Deployment
- A drogue is deployed over the stern of a boat or other vessel including autonomous and remote control.
- The drogue catches in the water creating enough drag to pull the net from its storage bin as the deploying vessel continues forwards.
- The initial drogue moves very little during deployment allowing the net to be precisely positioned.
- The deploying vessel can be traveling at up to 20 knots during the deployment.
- The net self-sets due to the action of floater and sinker lines top and bottom.
Net design
- The net is a cross between a Seine net (sea surface down) and a Gill net (sea bed up) and is intended to cover the entire water column.
- Nylon monofilament nets sink quicker than braided structures.
- Nylon netting is practically invisible underwater making evasion almost impossible.
- The net is fitted with a floating rope along the top edge and a lead core sinking rope to the bottom edge.
- This reduces snagging hazards associated with separate floats and weights.
- The net is made from 0.52mm nylon with a 7” stretch mesh.
- The net depth should be chosen for the specific area to be protected.
- GSA listings have been made for 200’ long nets in 10, 20, 30 and 40’ depth.
Anatomy of the net
The system can be deployed at speed, for the entire 200 foot length to stop threats in under ten seconds, protecting the entire water column from the surface to the seabed, for up to 40′ depth.
The system keeps ports and harbors with high value assets, safe from underwater threats.
The system can be deployed in under ten seconds protecting the entire water column from the surface to the seabed of 40′.
As sonars detect an object approaching a High Interest Vessel (HIV) or other high value asset a patrol vessel manned or autonomous is rapidly deployed with the net to drop a protective screen in the water protecting the asset.
Once the target is caught a team can be brought in to safely dispose of it.
Maritime Arresting Technologies continues to develop technologies to protect high value assets from above and below the waves.
