Raytheon Integrated Defense Systems is being awarded a modification to a previously awarded contract for one AEGIS weapon system AN/SPY-1D (V) transmitter group in support of DDG-127.
The undefinitized contract action modification, valued at around $48 million, was awarded by the U.S. Naval Sea Systems Command (NAVSEA) located in Washington DC. Fiscal 2016 shipbuilding and conversion (Navy) funding in the amount of around $22 million will be obligated at time of award and will not expire at the end of the current fiscal year.
Work will be performed in Andover, Massachusetts (79 percent); Marlborough, Massachusetts (19 percent); Moorestown, New Jersey (one percent); and Chesapeake, Virginia (one percent), and is expected to be completed by January 2020.
DDG-127 will be an Arleigh Burke-class destroyer of the United States Navy. She is the fourth of the Flight III variants and 77th overall in the class.
AN/SPY-1 is a U.S. naval 3D radar system manufactured by Lockheed Martin. The array is a passive electronically scanned array (PESA) system and is a key component of the Aegis Combat System.
The system is computer controlled, using four complementary antennas to provide 360 degree coverage. The system was first installed in 1973 on the USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga.
The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, CG-73.
SPY-1D was first installed on Arleigh Burke in 1991, with all antenna in a single deckhouse. It is a variant of the -1B to fit the Arleigh Burke class using UYK-43 computer, with the main antenna also used as missile uplinks, thus eliminate the need of separate missile uplink in earlier models, and the UYA-4 display in earlier models is replaced by UKQ-21 display.
It is designed for U.S. Navy Arleigh Burke-class destroyers, Japanese JDS Kongō-class destroyers and Spanish Armada Álvaro de Bazán-class frigates.
SPY-1D(V), the Littoral Warfare Radar, was an upgrade introduced in 1998 with new track initiation processor for high clutter near-coast operations, where the earlier “blue water” systems were especially weak. The wave form is coded and signal processing is improved.
About Arleigh Burke-class:
Arleigh Burke class of guided missile destroyers (DDGs) is the United States Navy’s first class of destroyer built around the Aegis Combat System and the SPY-1D multifunction passive electronically scanned array (PESA) radar.
The class is named for Admiral Arleigh Burke, the most famous American destroyer officer of World War II, and later Chief of Naval Operations. The class leader, USS Arleigh Burke, was commissioned on 4 July 1991 during Admiral Burke’s lifetime.
With an overall length of 505 to 509 feet (154 to 155 m), displacement ranging from 8,315 to 9,200 tons, and weaponry including over 90 missiles, the Arleigh Burke class are larger and more heavily armed than most previous ships classified as guided missile cruisers. Their hull and superstructure were designed to have a reduced radar cross section.
These warships were designed as multimission destroyers to fit the anti-aircraft warfare (AAW) role with their powerful Aegis radar and surface-to-air missiles; antisubmarine warfare (ASW), with their towed sonar array, anti-submarine rockets, and ASW helicopter; antisurface warfare (ASuW) with their Harpoon missile launcher; and strategic land strike role with their Tomahawk missiles.
With upgrades to their AN/SPY-1 phased radar systems and their associated missile payloads as part of the Aegis Ballistic Missile Defense System, the ships of this class have also begun to demonstrate some promise as mobile antiballistic missile and anti-satellite weaponry platforms.
Besides the 62 vessels of this class (comprising 21 of Flight I, 7 of Flight II and 34 of Flight IIA), up to a further 42 (of Flight III) have been envisioned.
