The $3.2m production and delivery contract covers the delivery of a number of security systems by the company to the navy for deployment at various coastal sites and offshore installations.
With deliveries scheduled to continue throughout 2013, the modification contract is also expected to further bolster maritime security of the nation.
The navy is currently using DSIT-built AquaShield diver detection sonar (DDS) and PointShield portable diver detection sonar (PDDS) systems to guard its critical assets.
Designed to provide automatic detection, tracking and classification capability for scuba and closed circuit divers for effective response, the AquaShield surveillance system enables the user to effectively determine the need and improve response times.
In addition, the system offers low false alarm rate and increased reliability, as well as reduced maintenance.
DSIT president and CEO Benny Sela said: "The underwater venue is the perfect cover for the stealthy approach of threats, and it is essential to guard against this danger.
"The customer understands that deployment of these additional AquaShield underwater perimeter security systems will further strengthen the country’s underwater defences."
Capable of operating in all weather and water conditions, the AquaShield DDS system’s sensors can be integrated with other sensors into a comprehensive command and control (C&C) system to provide more intelligent evaluation and effective response to the threat.
The AquaShield underwater system is also used to support operations for homeland security agencies, oil and gas (O&G) companies, nuclear power facilitie, port authorities, as well as yachts and coastal homes.
