An Template:Sclass-

The AMDR (Air and Missile Defense Radar, now officially named AN/SPY-6)[1] is an active electronically scanned array[2] air and missile defense 3D radar under development for the United States Navy.[3] It will provide integrated air and missile defense, and even periscope detection, for the Flight III Template:Sclass-s.[4]

Development

On October 10, 2013, "Raytheon Company (RTN) [was] awarded a $385,742,176 cost-plus-incentive-fee contract for the Engineering and Manufacturing Development (EMD) phase design, development, integration, test and delivery of Air and Missile Defense S-band Radar (AMDR-S) and Radar Suite Controller (RSC)." [5] In September 2010, the Navy awarded technology development contracts to Northrop Grumman, Lockheed Martin, and Raytheon to develop the S-band radar and radar suite controller (RSC). X-band radar development reportedly will come under separate contracts. The Navy hopes to place AMDR on Flight III Arleigh Burke-class destroyers, possibly beginning in 2016. Those ships currently mount the Aegis Combat System, produced by Lockheed Martin.[6]

In 2013, the Navy cut almost $10 billion from the cost of the program by adopting a smaller less capable system that will be challenged by "future threats".[7] As of 2013 the program is expected to deliver 22 radars at a total cost of $6,598m; they will cost $300m/unit in serial production.[8] Testing is planned for 2021 and Initial operating capability is planned for March 2023.[8] The Navy then was forced to halt the contract in response to a challenge by Lockheed.[9] Lockheed officially withdrew their protest on January 10, 2014[10], allowing the Navy to lift the stop work order.[11]

Technology

The AMDR system consists of two primary radars and a radar suite controller (RSC) to coordinate the sensors. An S-band radar is to provide volume search, tracking, ballistic missile defense discrimination and missile communications while the X-band radar is to provide horizon search, precision tracking, missile communication and terminal illumination of targets.[6] The S-band and X-band sensors will also share functionality including radar navigation, periscope detection, as well as missile guidance and communication. AMDR is intended as a scalable system; the Burke deckhouse can only accommodate a 4.3 m (14 ft) version but the USN claim they need a radar of 6.1 m (20 ft) or more to meet future ballistic missile threats.[8] This would require a new ship design; Ingalls have proposed the Template:Sclass- as the basis for a ballistic missile defense cruiser with 6.1 m (20 ft) AMDR. To cut costs the first twelve AMDR sets will have an X-band component based on the existing SPQ-9B rotating radar, to be replaced by a new X-band radar in set 13 that will be more capable against future threats.[8] The transmit-receive modules will use new gallium nitride semiconductor technology.[8] This will allow for higher power density than the previous gallium arsenide radar modules.[12] The new radar will require twice the electrical power as the previous generation while generating over 35 times as much radar power.[13]

Although it was not an initial requirement, the AMDR may be capable of performing electronic attacks using its AESA antenna. Airborne AESA radar systems, like the APG-77 used on the F-22 Raptor, and the APG-81 and APG-79 used on the F-35 Lightning II, and F/A-18 Super Hornet/EA-18G Growler respectively, and have demonstrated their capability to conduct electronic attack. The contenders for the Navy's Next Generation Jammer all used Gallium Nitride-based (GaN) transmit-receiver modules for their EW systems, which enables the possibility that the high-power GaN-based AESA radar used on Flight III ships can perform the mission. Precise beam steering could attack air and surface threats with tightly directed beams of high-powered radio waves to electronically blind aircraft, ships, and missiles.[14]

The radar is 30 times more sensitive and can simultaneously handle over 30 times the targets of the existing AN/SPY-1D(V) in order to counter large and complex raids.[15]

Versions
