Thales Selected by Lockheed Martin to Deliver Airborne Anti-submarine Warfare Sonars to the U.S., Indian, Greek and Danish Navies

  • Lockheed Martin and Thales closed negotiations for the supply up to 55 ALFS anti-submarine warfare sonars to the U.S. Navy and foreign navies.
  • As a tier-one supplier to Lockheed Martin, Thales will deliver the ALFS systems for installation on the MH-60R helicopter platform.
  • The navies of India, Greece and Denmark will receive the helicopter dipping sonars through U.S. Foreign Military Sales of the MH-60R.

PARIS LA DÉFENSE--(BUSINESS WIRE)--Thales has signed a contract with Lockheed Martin as a tier-one supplier for the delivery of up to 55 airborne anti-submarine warfare sonars. The ALFS (Airborne Low Frequency Sonar)* dipping sonars will be installed on the MH-60R platform for the U.S. Navy and three navies. Delivery of the first 42 systems will occur over the next five years with a delivery of 13 optional systems to occur in year six.

Thales has delivered more than 300 ALFS sonars to the U.S. Navy since the early 2000s and this new contract with Lockheed Martin will continue to support the Navy’s readiness strategy. The navies of India, Denmark and Greece will receive their first deliveries of the ALFS sonar system through direct U.S. Foreign Military Sales of the MH-60R platforms.

To maintain control over their maritime space and protect security interests around the world, naval forces need reliable, high-performing systems to operate with optimum effect on missions including anti-submarine warfare, maritime search and rescue, defence of maritime approaches and fleet protection for naval forces on deployment.

Offering unparalleled protection to maritime convoys, the ALFS anti-submarine warfare system is capable of detecting, classifying, prosecuting, harassing or attacking submarines, making Thales the benchmark for the world’s major navies. In addition to the U.S. Navy, the other navies that have chosen Thales dipping sonar solutions include the navies of Australia, the United Kingdom, France, Norway, Sweden, the United Arab Emirates, Poland, South Korea and the Philippines.

As a low frequency active sonar, ALFS is designed for the initial detection and tracking of opposing submarines. It offers a long detection range with a wide coverage rate and a low false alarm level, both in deep and coastal waters. It can be used autonomously to clear a particular area or as a complementary anti-submarine warfare asset to sonars on board surface vessels for target relocation and attack.

“Earning the trust of the U.S. Navy and its allies and partners around the globe is a source of pride for our team. This contract enhances our position as a strategic supplier to Lockheed Martin and further consolidates the Group's world leadership position in anti-submarine warfare systems. We will continue to improve the performance and competitiveness of our airborne sonars to meet the new anti-submarine warfare operational challenges of our customers.” Alexis Morel, VP Underwater systems, Thales.

Note to Editors

* The Thales ALFS and FLASH systems are from the same product family of airborne anti-submarine dipping sonars but each product has variances due to system destinations and the local technological requirements to comply with including U.S. ITAR.
