Leonardo’s ULISSES system was used to automatically locate a number of simulated submarines in a live trials exercise.
Leonardo say it has proven the submarine-hunting capabilities of its new ULISSES acoustic sensor system in a live sea trial off the coast of Italy, meaning that development is on track for completion by the end of 2019.
Production will now take place in 2020 for deliveries the same year and Leonardo is in talks with a number of potential domestic and international customers.
According to the firm:
“ULISSES (Ultra-LIght SonicS Enhanced System) is an integrated acoustic sensor system designed to ‘listen’ for hostile submarines and determine their locations. Uniquely in the market, ULISSES incorporates ‘multistatic’ functionality, where the processor collects and exploits data from up to 64 distributed sonobuoys or dipping sonar sensors, which are processed in parallel.
It then uses the multiple sources of information to triangulate the location of potentially hostile vessels. Leonardo announced the development of the acoustic system, in partnership with Ultra Electronics (providing miniaturised sonobuoys and multistatic technology) and L3 Technologies (providing dipping sonar), at the 2018 Farnborough Air Show. The system is now available to order.”
The firm say that the recent sea trials began with Leonardo deploying various types of Ultra Electronics supplied sonobuoys, including some with GPS, from a ship. The ULISSES processor was then used to quickly and accurately locate a number of simulated under-sea targets, automatically marking their coordinates on a map on the operator’s workstation.
Leonardo say that the success of the trials means that development of the system is on track to wrap up by the end of December, with production ready to start next year.
