The DDG-51 AEGIS Destroyer

About the AEGIS Destroyer:

The DDG 51 Arleigh Burke Class AEGIS Destroyer (named after the famous U.S. Navy destroyer squadron commander Admiral Arleigh Burke) is a type of multi-mission guided missile destroyer designed to perform anti-submarine warfare (ASW), anti-air warfare (AAW), and anti-surface warfare (SuW) missions in support of U.S. naval operations. DDG 51 ships support carrier strike groups, surface action groups, and replenishment groups.

The DDG 51 is an important component of the AEGIS Ballistic Missile Defense (BMD) System, where it - together with Ticonderoga Class Missile Cruisers (CG 47) - patrols the oceans to detect and track ballistic missiles of all ranges, including Intercontinental Ballistic Missiles (ICBM). The tracking data is then reported to the U.S. Ballistic Missile Defense System (BMDS).

The Arleigh Burke Class ships are constructed by General Dynamics-Bath Iron Works (lead yard) and Huntington Ingalls and to date, a total of 62 destroyers have been delivered. The Arleigh Burke Class AEGIS Destroyer is widely recognized as the most successful surface shipbuilding program since the Second World War.

The DDG 51 is powered by four General Electric LM2500 marine gas simple-cycle high-performance turbine engines, each delivering 33,600 shp. The LM2500 is derived from the GE CF6 turboshaft aircraft engine.

At the core of DDG 51 shipboard systems is the Lockheed Martin-developed AEGIS Combat System, an integrated missile guidance system used on U.S. Navy and allied ships. The system operates as an integrated single ship system, as well as in ship-to-ship networks. The key component of the AEGIS Combat System is the Raytheon AN/SPY-1D(V) multi-function phased array radar, the most advanced and versatile maritime radar in the world. The role of the radar is to acquire and track targets such as planes and missiles and defend against them. In October 2013, Raytheon won a contract to design the next-generation Air and Missile Defense Radar (AMDR), which will replace the AN/SPY-1D on DDG 51 destroyers starting in 2016 (Flight III). Other electronic systems onboard include the Northrop Grumman AN/SPQ-9B, a multimode X-band pulse doppler radar that detects sea skimming missiles; the Lockheed Martin AN/SQQ-89A(V)15 Undersea Warfare / Anti-Submarine Warfare Combat System; the Raytheon AN/SLQ-32(V) Shipboard Electronic Warfare (EW) System; the AN/USQ-82(V) Gigabit Ethernet Data Multiplex System (GEDMS) from DRS Technologies; and the Raytheon AN/APX-100 Mk 12 IFF transponder set.

DDG 51 is an all-steel construction and features four separate variants so-called Flights. The ships from DDG 51 to 71 represent the original design and are designated as Flight I ships, DDGs 72 to 78 are Flight II ships, while DDGs 79 to 122 employ the Flight IIA design. The first Flight III ship, DDG 123, is expected to enter service in 2022 and as many as 42 Flight III ships may be purchased.

Construction of Flight IIA ships started with DDG 79 USS Oscar Austin commissioned in August 2000. The Flight IIA design includes the addition of the Kingfisher mine-avoidance system; helicopter hangars with space for two MH-60R Seahawk helicopters; blast-hardened bulkheads; a distributed electrical system; and advanced networked systems. Additionally, DDGs 91 to 96 provide accommodations for the AN/WLD-1 Remote Mine-Hunting System. U.S. Navy Flight IIA requirements have involved various modifications to secondary armaments, in that some ships have a Close-In Weapon System (CIWS) installed and some vessels employ a storage/launch facility to hold a single minehunting Under Sea Vehicle (USV). Flight III will meet ballistic missile defense and open ocean anti-submarine warfare (ASW) requirements. It is anticipated that the Flight III design will replace the AEGIS AN/SPY-1D(V) radar with the Air and Missile Defense Radar (AMDR), currently being developed for the AEGIS Combat System.

Launched in May 2011, DDG 112 USS Michael Murphy (the last Flight IIA ship) was commissioned on October 6, 2012.

On June 3, 2013, General Dynamics BIW was awarded a $2.84 billion contract for the design and construction of four DDG 51 class ships, one in FY 2013 and one each in FYs 2015-2017. This award also includes a contract option for a fifth ship. Also, Huntington Ingalls was awarded a $3.33 billion contract for the design and construction of five DDG 51 class ships, one each in FYs 2013-2017.

The development of the DDG 1000 Zumwalt Class Next-Generation Destroyer caused an interruption in the DDG 51 program, which has since been reinstated due to the DDG 51's important role in ballistic missile defense, a capability not offered by Zumwalt Class destroyers.

Armament/Ship Self-Defense:

The DDG 51 is equipped with two Mk 41 Vertical Launching Systems (VLS) that together accommodate a total of 90 Standard Missile (SM-2/SM-6), RUM-139 VL-ASROC, and RGM-109E Tactical Tomahawk missiles. The DDG 51 also features a 5-inch Mk 45 127mm gun, which provides surface fire support to forces on land and + an anti-ship gun capability; two Raytheon Mk 15 Phalanx 20mm Close In Weapon Systems (CIWS); two Mk 32 triple 324mm torpedo tubes with a total of six Mk 46/50/54 torpedoes; four .50 caliber (12.7mm) machine guns; and two Alliant Techsystems M242 Bushmaster 25mm chain guns. DDGs 79 and up also feature the RIM-162 Evolved Sea Sparrow Missile. For more detail, see specifications below.

Price/Unit Cost:

In FY 2015, the unit cost of a DDG 51 Destroyer is $1.48 billion (end cost).

Total Cost - Life of Program (LoP):

The total procurement cost of the DDG 51 program is $89.73 billion (estimated by the DoD) + $4.25 billion in research and development (RDT&E) funds, which means the total estimated program cost is $93.98 billion (numbers are aggregated annual funds spent over the life of the program and no price/inflation adjustment was made). This figure excludes military construction (MILCON) costs in support of the program in the amount of $44.5 million.


The DDG 51 AEGIS Destroyer provides an anti-submarine warfare (ASW), anti-air warfare (AAW), and anti-surface warfare (SuW), and land attack capability.

FY 2015 DoD Program:

Funds two DDG 51 AEGIS destroyers (DDG 121 and DDG 122). Procurement funds in the amount of $3,255.8 million have been provided for the DDG 51 Program.

FY 2016 DoD Program:

Funds two DDG 51 AEGIS class destroyers (DDG 123 and DDG 124) as part of a multiyear procurement contract for ten ships from FY13-FY17. Procurement funds in the amount of $3,576.0 million have been provided for the DDG 51 Program.
