Aegis system
Aegis system
The Aegis combat system is an integrated weapons system used by the United States Navy. It is both an integrated single ship system and a ship-to-ship network. The Aegis combat system is one of the most advanced and most capable defense systems currently in use. It is also used by the Japan Maritime Self-Defense Force, Spanish Navy, Royal Norwegian Navy, and Republic of Korea Navy. The Royal Australian Navy has selected the Aegis system for placement on their new destroyers. A total of 108 Aegis-equipped ships have been deployed in five navies worldwide.
Aegis was initially developed by the Missile and Surface Radar Division of RCA, which was then acquired by General Electric. The division responsible for the Aegis systems became Government Electronic Systems. This, and other GE Aerospace businesses, were sold to Martin Marietta in 1992.[1] This became part of Lockheed Martin in 1995.
Overview
The Aegis weapon system is an advanced combat, control, and information system that uses powerful computers and radars to track and destroy enemy targets. It is the most advanced modern combat system and is the first fully integrated combat system built to defend against air, surface, and subsurface threats.
The Aegis Weapons System comprises the SPY-1 Radar, MK 99 Fire Control System and ORTS, MK 41 VLS, the Command and Decision Suite, and SM-2 Standard Missile systems. Shipboard torpedo and naval gunnery systems are also integrated.[2] The Aegis combat system is controlled by an advanced, automatic detect-and-track, multi-function three-dimensional passive electronically scanned array radar, the AN/SPY-1. Known as "the Shield of the Fleet", the SPY high-powered (four megawatt) radar is able to perform search, tracking, and missile guidance functions simultaneously with a track capacity of well over 100 targets at more than 100 nautical miles (190 km).[3]
The Aegis system uses missile uplink using the AN/SPY-1 radar for midcourse guidance of Standard missiles during engagements, but still requires the AN/SPG-62 radar for terminal guidance. This means that with proper scheduling of intercepts, a large number of targets can be engaged simultaneously.
The computer-based command-and-decision element is the core of the Aegis combat system. This interface makes the Aegis combat system capable of simultaneous operation against almost all kinds of threats. The Aegis system is being enhanced to act in a Theater Missile Defense role, to counter short- and medium-range ballistic missiles of the variety typically employed by rogue states (see Aegis Ballistic Missile Defense System).
Development
By the late 1950s, the US Navy replaced guns with guided missiles on its ships. These were sufficient weapons but by the late 1960s, the U.S. Navy recognized that reaction time, firepower, and operational availability in all environments did not match the anti-ship missile threat.
As a result, the US Navy decided to develop a program to defend ships from anti-ship missile threats. An Advanced Surface Missile System (ASMS) was promulgated and an engineering development program was initiated to meet the requirements. ASMS was re-named "Aegis" in December 1969 after the aegis, the shield of the Greek god Zeus. The name was coined at the suggestion of Captain L. J. Stecher, a former Tartar Weapon System manager, after an internal U.S. Navy contest to name the ASMS program was initiated. Captain Stecher also submitted a possible acronym of Advanced Electronic Guided Interceptor System although this definition was never used.[4] While many other meanings have been attributed to the name Aegis, the name is not an acronym. The main manufacturer of the Aegis combat system, Lockheed Martin, makes no mention of it being an acronym, nor does the U.S. Navy.
The first Engineering Development Model (EDM-1) was installed in a test ship, the USS Norton Sound, in 1973. This was the first fully-operational seaborne phased-array RADAR. The Navy built the first Aegis-equipped cruisers using the hull and machinery designs of Spruance-class destroyers. The first cruiser of this class was the Ticonderoga, which uses two twin-armed Mark-26 missile launchers, fore and aft. The commissioning of the sixth ship of the class, the Bunker Hill opened a new era in surface warfare as the first Aegis ship outfitted with the Martin Marietta Mark-41 Vertical Launching System (VLS), allowing a wider missile selection, more firepower, and survivability. The improved AN/SPY-1B radar went to sea in the Princeton, ushering in another advance in Aegis capabilities. The Chosin introduced the AN/UYK-43/44 computers, which provide increased processing capabilities.
In 1980, a destroyer was designed using an improved sea-keeping hull form, reduced infrared, and radar cross-section and upgrades to the Aegis Combat System. The first ship of the Arleigh Burke class, the USS Arleigh Burke, was commissioned in 1991. Because the Aegis system dominates the ship's architecture, ships equipped with it are sometimes mistakenly called Aegis class ships.
Flight II of the Arleigh Burke class, introduced in 1992, incorporated improvements to the SPY radar, and to the Standard missile, active electronic countermeasures, and communications. Flight IIA, introduced in 2000, added a helicopter hangar with one anti-submarine helicopter and one armed attack helicopter. The Aegis program has also projected reducing the cost of each Flight IIA ship by at least $30 million.
Aegis in other navies
Australia, under its Sea 4000 project to acquire three air warfare destroyers, decided in August 2004 that Aegis would be the core of the combat system for the Royal Australian Navy ships. On 20 June 2007, the Australian government announced it had selected the Navantia F-100 Álvaro de Bazán class design over a variant of the Arleigh Burke design. The Australian variant will be known as the Hobart class.
Japan operates four Kongō-class destroyers of a modified Arleigh Burke design from 1993. Two improved units known as the Atago class were purchased in 2000 and the first ship of this class, DDG 177 Atago, was commissioned March 15, 2007.
Norway is procuring five ships of Spanish manufacture which include a U.S. sourced Aegis system integrated onto the ships, as the Fridtjof Nansen class. The first unit of this type, Fridtjof Nansen, was launched on June 3, 2004. The second of five Norwegian Nansen class frigates, the Roald Amundsen, completed its sea trials and entered service in June 2007. The 5,200 ton Nansen class ships are being built in Spain and cost $600 million each.
Republic of Korea is building Aegis variants of its KDX destroyers, called KDX-III. The first ship of the class, King Sejong the Great, was launched on May 25, 2007.
Spain is currently operating five Álvaro de Bazán class Aegis frigates, with at least four in commission.

LGM-30 Minuteman III
Five hundred Minuteman III missiles are deployed at four bases in the north- central United States: Minot AFB and Grand Forks AFB, North Dakota, Malmstrom AFB, Montana, and F. E. Warren AFB, Wyoming. Operational since 1968, the model "G" differs from the "F" in the third stage and reentry system. The third stage is larger and provides more thrust for a heavier payload. The payload, the Mark 12 reentry system, consists of a payload mounting platform, penetration aids, three reentry vehicles (RVs) and an aerodynamic shroud. The shroud protects the RVs during the early phases of flight. The mounting platform is also a "payload bus" and contains a restartable hypergolic rocket engine powered by hydrazine and nitrogen tetroxide. With this configuration, the RVs can be independently aimed at different targets within the missile's overall target area or "footprint". This concept is known as Multiple Independently Targeted Reentry Vehicles (MIRV).
The LGM-30 Minuteman missiles are dispersed in hardened silos to protect against attack and connected to an underground launch control center through a system of hardened cables. Launch crews, consisting of two officers, perform around-the-clock alert in the launch control center. A variety of communication systems provide the National Command Authorities with highly reliable, virtually instantaneous direct contact with each launch crew. Should command capability be lost between the launch control center and remote missile launch facilities, specially-configured EC-135 airborne launch control center aircraft automatically assume command and control of the isolated missile or missiles. Fully qualified airborne missile combat crews aboard airborne launch control center aircraft would execute the NCA orders.
The Minuteman weapon system was conceived in the late 1950s and deployed in the early 1960s. Minuteman was a revolutionary concept and an extraordinary technical achievement. Both the missile and basing components incorporated significant advances beyond the relatively slow-reacting, liquid-fueled, remotely-controlled intercontinental ballistic missiles of the previous generation. From the beginning, Minuteman missiles have provided a quick-reacting, inertially guided, highly survivable component to America's nuclear Triad. Minuteman's maintenance concept capitalizes on high reliability and a "remove and replace" approach to achieve a near 100 percent alert rate.
By the time the last Minuteman IIs of the 564th SMS were placed on strategic alert in the spring of 1967, significant progress had been made on the development of an even more advanced ICBM. The Minuteman III, using modernized Minuteman I and Minuteman II ground facilities, provided reentry vehicle and penetration aids deployment flexibility, increased payload, and improved survivability in a nuclear environment. Its liquid injection attitude control system with a fixed nozzle on an improved third stage motor increased the Minuteman's range and the Minuteman III reentry system could deploy penetration aids and up to three Mark 12 or Mark 12A multiple independently-targetable reentry vehicles. A liquid-fueled post-boost propulsion system maneuvered the missile prior to deployment of the reentry vehicles, while upgraded guidance system electronics enhanced computer memory and accuracy.
On 17 April 1970, an important Minuteman III milestone was reached when the first missile was placed in a silo assigned to the 741st Strategic Missile Squadron, Minot AFB, North Dakota. At the end of December, the 741st SMS became the first SAC Minuteman III squadron to achieve operational status.
Strategic Air Command expected Minuteman to play an important role in the command's force structure beyond the year 2000. To ensure the reliability and maintainability of the Minuteman force into the next century, the Air Force initiated a major Minuteman upgrade and modification program. Rivet MILE (Minuteman Integrated Life Extension Program) began 1 April 1985 at the 341st Strategic Missile Wing, Malmstrom AFB, Montana. This joint Strategic Air Command and Air Force Logistics Command effort was the largest single missile logistics program ever undertaken within the ICBM program.
Through state-of-the-art improvements, the Minuteman system has evolved to meet new challenges and assume new missions. Modernization programs have resulted in new versions of the missile, expanded targeting options, significantly improved accuracy and survivability. Today's Minuteman weapon system is the product of almost 35 years of continuous enhancement.
Peacekeeper missile deployment also affected the Minuteman force. As part of the strategic modernization program undertaken in 1982, Strategic Air Command deployed fifty Peacekeeper missiles in modified Minuteman III silos assigned to the 400th Strategic Missile Squadron, 90th Strategic Missile Wing, F.E. Warren AFB, Wyoming. Conversion began on 3 January 1986, when the first Minuteman came off alert, and the phaseout of the 400th SMS's Minuteman IIIs was completed on 11 April 1988.
The current Minuteman force consists of 530 Minuteman III's located at F.E. Warren Air Force Base, Wyo.; Malmstrom AFB, Mont.; Minot AFB, N.D.; and Grand Forks AFB, N.D. As a result of U.S. initiatives to cancel development programs for new intercontinental ballistic missiles and retire the Peacekeeper ICBM, Minuteman will become the only land-based ICBM in the Triad. To compensate for termination of the Small ICBM and Peacekeeper Rail Garrison programs, DOD will conduct an extensive life extension program to keep Minuteman viable beyond the turn of the century. These major programs include replacement of the aging guidance system, remanufacture of the solid-propellant rocket motors, replacement of standby power systems, repair of launch facilities, and installation of updated, survivable communications equipment and new command and control consoles to enhance immediate communications.
In order to meet warhead levels set by START II, the United States has decided to permanently DEMIRV Minuteman III missiles from their current capability to carry up to three reentry vehicles to a newly configured single reentry vehicle system once the treaty enters into force. "Downloading" Minuteman III missiles from three reentry vehicles to one lowers the military value of each missile; reduces the likelihood of any country expending resources to preemptively attack America's ICBM force; and decreases the probability of future US leaders being force into a "use or lose" position. For a downsized force of 500 single reentry vehicle Minuteman III to continue to be an effective deterrent force, the guidance replacement program will improve the needed accuracy and supportability that is inherent in a smaller missile force. Peacekeeper missiles will be deactivated by 2003, provided START II is ratified and enters into force. Ultimately, a total of 500 single RV Minuteman IIIs will be the nation's ICBM deterrent force through 2020.
