With little fanfare or pomp, General Dynamics Bath Iron Works (BIW) floated the first of the next-generation Zumwalt-class guided missile destroyers (DDG-1000), Naval Sea Systems Command (NAVSEA) announced on Tuesday. Read More
When the first new Flight III Arleigh Burke-class destroyer enters service with the U.S. Navy in 2019, it will be equipped with a new radar roughly 30 times more powerful than the long-serving Lockheed Martin SPY-1 system found on current Aegis warships. Called the air and missile defense radar (AMDR), the new sensor is expected to exponentially increase the ship’s performance in simultaneously defending the Fleet against both air-breathing and ballistic-missile threats. The key technology that enables such high performance is a semiconductor called gallium nitride (GaN).
“It is definitely one of the key enabling technologies,” said Captain Douglas Small, Naval Sea Systems Command’s AMDR program manager, during an interview with USNI News. “We’re basically in the Flight III going to deliver over 30 times the radar capability for about twice the input power.” Read More
The Navy has awarded $6.1 billion in contracts to Huntington Ingalls Industries (HII) and General Dynamic Bath Iron Works (BIW) for nine Arleigh Burke–class guided missile destroyers (DDG-51) to be purchased between Fiscal Years 2013 to 2017 in a massive multi-year shipbuilding deal, Naval Sea Systems Command told USNI News on Monday.
The contract award has HII building five of the hulls for $3.3 billion and BIW four for $2.8 billion. The multi–year deal — starting with future ships Paul Ignatius (DDG-117) and Daniel Inouye (DDG-118) — includes an option for a tenth DDG-51 if the Navy can overcome a sequestration funding challenge. The extra ship would likely be built in 2014 by BIW, NAVSEA said. Read More
