ITT [ITT] recently said it won a contract from the Norwegian Defense Logistics Organization to provide six tactical radar Electronic Support Measures (ESM) and surveillance systems for its Ula-class submarines.

“With our established in-country support and ability to offer early delivery of a solution that provides commonality across the Norwegian fleet, ITT is committed to helping Norway achieve its mission,” Bill Devlin, vice president of ITT’s Radar Reconnaissance and Acoustic Systems business area, said in a statement. “This win continues to position us as a premier international supplier of ESM systems.”

Because of the competitive and classified nature of the contract, terms of the deal could not be released without additional customer approval, a spokesperson for the company told sister publication Defense Daily.

ESM systems play an important role in a submarine’s defenses, ITT said. By monitoring electromagnetic energy, the crew can detect, intercept, locate, or analyze sources of those signals to detect other vessels or objects, and determine if any of these are a threat to the submarine.

ITT’s solution, based on its ES-3701 precision ESM system, is in use by numerous navies around the world. The system is ideally suited for ship, submarine and coastal surveillance, as well as land-based applications. In addition, the equipment has advanced capabilities for long-range radar signal acquisition, classification and intelligence, the company added.

Work will be performed by ITT’s Radar, Reconnaissance and Acoustic Systems business area, a leader in global solutions for battlespace situational awareness, electronic warfare and countermeasures.
