Lockheed Martin was awarded a $182 million contract for airborne low-frequency sonars (ALFS) related to Indian and Danish Sikorsky MH-60R anti-submarine warfare helicopters.
The contract modification, announced Tuesday by the U.S. Department of Defense, is worth more than $182 million and covers production, delivery and integration of 24 ALFSs for the government of India; eight ALFSs for the Navy and seven ALFS for the government of Denmark, into MH-60R Seahawk helicopters.
In May, Sikorsky signed a $905 million contract for New Delhi’s 24 MH-60Rs, with the first delivery expected in 2021.
Cirium fleets data indicates that the Royal Danish Air Force operates nine MH-60Rs with an average age of 3.3 years.
The ALFS is the primary undersea warfare sensor of the MH-60R multi-mission helicopter. This integrated dipping sonar system enables the MH-60R to accomplish the assigned ASW missions of submarine detection, tracking, localization and classification. It also performs missions relating to acoustic intercept, underwater communications and environmental data acquisition.
Work is expected to be completed by Lockheed Martin in September 2024.
