The Naval Sea Systems Command contracted
Raytheon’s Integrated Defense System business with $38.1 million for engineering services for the Dual Band Radar (DBR) System
. Raytheon’s DBR is capable of simultaneously operating over two frequency ranges (S-band and X-band), coordinated by a single resource manager. It does not require a dedicated operator or manned display consoles. Its separate band radar arrays provide extensive search, track and multiple missile illumination capacity. DBR
also provides target illumination and uplink/downlink capabilities for SM-2 and Evolved SeaSparrow missiles. Per the terms of the contract, Raytheon conducts technical engineering services for DBR system upgrades, product support services, test equipment procurement, installation integration support, combat system integration testing, program management support, along with other studies and analysis. Work will be performed in Massachusetts, New Jersey, and Virginia. The company will utilize 2019 shipbuilding and conversion (Navy), and fiscal 2019 research, development, test, and evaluation funds for the task.
The DBR concept involves a significant change from current naval design approaches, and that change is not without risk. The USA’s GAO audit office remains concerned that key tests may not happen before the radar is installed on new ships, and any more development or testing snags could put much larger programs at risk. In April 2009, a successful full-power “lightoff” of both DBR radars was encouraging, but 2010 saw a major program shift. Sharp drops in the planned number of DDG-1000 destroyer created a per-ship cost crisis. Part of the response involved a shift to a single X-band SPY-3 radar for the Zumwalt Class, leaving DBR as a dual-band SPY-3/ SPY-4 solution only on America’s new carriers.
