Lockheed Martin wins contract modification for DDG 127 AEGIS weapon system

Lockheed Martin Rotary and Mission Systems is being awarded a contract action in-scope modification for one AEGIS weapon system Mk 7 in support of DDG 127 as well as associated system-level integration testing at the production test center.

The undefinitized contract action modification, valued at around $73 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 $37 million will be obligated at time of award and will not expire at the end of the current fiscal year.

The work will be performed in Moorestown, New Jersey (59 percent); Clearwater, Florida (40 percent); and Owego, New York (1 percent), and is expected to be completed by September 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.

AEGIS Weapon System (AWS)

AEGIS Weapon System (AWS) is the heart of Aegis Combat System (ACS), an integrated naval weapons system developed by the Missile and Surface Radar Division of RCA, and now produced by Lockheed Martin.

ACS is an advanced command and control/ C2 (command and decision, or C&D, in Aegis parlance) and weapon control system that uses powerful computer and radar technology to track and guide weapons to destroy enemy targets.

AWS is the fast-reaction component of the Aegis Anti-Aircraft Warfare (AAW) capability, along with the Phalanx Close In Weapon System (CIWS), and the Mark 41 Vertical Launch System (VLS).

The system is comprised of the AN/SPY-1 3D PESA Radar, MK 99 Fire Control System, Weapon control system (WCS), the Command and Decision Suite, and SM-2 Standard Missile family of weapons; these include the basic RIM-66 Standard, the RIM-67 extended range missile, and the newer RIM-161 designed to counter ballistic missile threats.

A further SM-2 based weapon, the RIM-174 Standard ERAM (SM-6) was deployed in 2013. Individual ships may not carry all variants. Weapons loads are adjusted to suit assigned mission profile.

Initially used by the United States Navy (USN), Aegis is now used also by the Japan Maritime Self-Defense Force (JMSDF), Spanish Navy (AE), Royal Norwegian Navy (RNoN), and Republic of Korea Navy (ROKN).

Over 100 Aegis-equipped ships have been deployed in five navies worldwide.

Arleigh Burke-class DDG

Arleigh Burke class of guided missile destroyers (DDGs) is the U.S. 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.
