Arleigh Burke Class (Aegis) Destroyer
The entire ship (except the two aluminium funnels) is constructed from steel, with vital areas protected by two layers of steel and 70t of Kevlar armour.There is a platform for rearming and refuelling a LAMPS III SH-60B / F helicopter (with ASW capabilities), but no hangars, the ship is unable to house a helicopter of its own. This is the first US Navy class to be fitted out with anti-NBC warfare protection.
The Arleigh Burke Class destroyers are equipped with the Aegis combat system which integrates the ship's sensors and weapons systems to engage anti-ship missile threats.
The Aegis system has a federated architecture with four subsystems – AN / SPY-1 multifunction radar, command and decision system (CDS), Aegis display system (ADS) and the weapon control system (WCS). The CDS receives data from ship and external sensors via satellite communications and provides command, control and threat assessment. The WCS receives engagement instruction from the CDS, selects weapons and interfaces with the weapon fire control systems.
The latest Aegis upgrade, baseline 7.1, was certified by the USN in September 2005 onboard USS Pinkney (DDG 91). The upgrade includes a new radar, AN / SPY-1D(V), which has enhanced electronic countermeasures and more effective capability in littoral environments. Baseline 7.1 is based on COTS (commercial-off-the-shelf) computer architecture. Trials of the upgrade in March 2003 included live firings of the ESSM.
Lockheed Martin is developing the Aegis ballistic missile defence (BMD) capability for the Aegis combat system to engage ballistic missiles with the SM-3 missile. 15 Arleigh Burke destroyers have been fitted with the Aegis BMD system, which provides the capability for long-range surveillance, tracking and engagement of short and medium-range ballistic missiles.
The ships are armed with 56 Raytheon Tomahawk cruise missiles, with a combination of land-attack (TLAM) missiles with a Tercom aided navigation system, and anti-ship missiles with inertial guidance. The Standard SM-2MR block 4 surface-to-air missiles with command / inertial guidance remain at the centre of the Aegis system. Both Tomahawk and Standard missiles are fired from two Lockheed Martin mk41 vertical launch systems.
There are also eight Boeing Harpoon surface-to-surface missiles and Lockheed Martin ASROC vertical launch anti-submarine systems, armed with the mk50 or mk46 torpedo. ASROC is launched from the mk41 VLS.
Arleigh Burke vessels are fitted with the evolved Sea Sparrow missile (ESSM), developed by Raytheon. ESSM is an advanced ship self-defence missile for use against anti-ship missiles.
