L3 Technologies Receives $10M from U.S. Navy for Eight MH-60R CDL Hawklink AN/SRQ-4 Systems

L3 Technologies is awarded a $10 million contract modification from the U.S. Naval Air Systems Command (NAVAIR) for eight Common Data Link Hawklink (CDL Hawklink) AN/SRQ-4 systems for the U.S. Navy MH-60R Seahawk helicopters.

Work will be performed in Salt Lake City, Utah, and is expected to be completed in December 2022.

L3 CDL Hawklink

L3’s Ku-Band CDL Hawklink system is a high-speed digital data link that transmits tactical video, radar and acoustic sensor data from the U.S. Navy’s MH-60 Romeo Light Airborne Multi-Purpose System (LAMPS) helicopter to its host surface ship.

Comprising the AN/ARQ-59 airborne terminal and the AN/SRQ-4 shipboard terminal, the system will double the Hawklink’s current data rates for the MH-60R at ranges over 100 nautical miles and will support a full range of surveillance, anti-submarine warfare (ASW) and recovery missions.

Additionally, the system is suitable for a variety of platforms, providing extended range, high data rates, and proven operational reliability.

L3’s next-generation AN/SRQ-4 provides Command/Control (C2), sensor data transfer, data link operation and comprehensive built-in test. Radar, video, network and acoustic data interfaces meet shipboard interface requirements.

CDL Hawklink provides real-time exploitation of aircraft sensors, extending situational awareness over the horizon.

The features of the AN/SRQ-4 system includes:

• Supports Anti-Submarine Warfare (ASW) and Anti-Ship Surveillance and Targeting (ASST) missions
• Receives and distributes full-motion video
• IP enabled and extensible to future network-centric applications
• Compatible with SAU7000 Digital Messaging Interface
• Ruggedized construction and modules qualified to U.S. Navy shock and environmental requirements
• Expanded CDL frequency range to support MH-60R operations
• Maximizes link performance by auto-switching between open-loop pointing and closed-loop tracking depending on range between airborne platform and ship
• Range specified to 100 nm to AN/ARQ-59 airborne terminal
• Extensive built-in test avoids O-level support equipment
• Interoperable with CDL family of airborne terminals, including Fire Scout, P-3 and P-8
• Easy-to-use touchscreen graphical user interface for control and status
• Growth path to dual-link operation
