CG(X)
The CG(X) program, also known as the Next Generation Cruiser program, was a United States Navy research program to develop a replacement vessel for its 22 s. Original plans were for 18–19 ships, based on the 14,500 ton with additional ballistic missile defense and area air defense for a carrier group. These vessels were to enter service beginning in 2017. The program was ended in 2010 with its mission to be fulfilled by the successor to the Flight III ''Arleigh Burke''–class destroyers. History Background In the early 1990s, the U.S. Armed Forces had to respond to new threats and budgets after the end of the Cold War. The U.S. Navy's response was the Surface Combatant for the 21st Century (SC-21) program. This envisaged a destroyer called DD-21 and a planned cruiser called CG-21. Budget cuts in November 2001 meant that SC-21 became the less ambitious Future Surface Combatant program. The DD-21 was renamed DD(X), which was later named the destroyer. By April 2002, DD( ...

SC21 (United States)
SC-21 (Surface Combatant for the 21st century) was a research and development program started in 1994 intended to design land attack ships for the United States Navy. A wide variety of designs were created and extensively examined, including an arsenal ship with 500 cruise missiles. Eventually a "tumblehome" design of around 16,000 tons with two long-range guns and 128 missile tubes was selected as the DD-21, the Destroyer for the 21st century. The program ended in November 2001. Background The origins of SC-21 lie in the realization by Admiral Joseph Metcalf III that new technologies such as vertical launch missiles permitted a complete rethink of warship design. He established a steering group, Group Mike, to study the possibilities. Group Mike sponsored two studies in 1987: the Ship Operational Characteristics Study (SOCS) and the Surface Combatant Force Requirement Study (SCFRS). Respectively, these studies sought to identify the operational characteristics required of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SPY-3
The AN/SPY-3 is an active electronically scanned array radar manufactured by Raytheon and designed for both blue-water and littoral operations. Technology X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM). The X-band has, in general, favorable low-altitude propagation characteristics, which readily support the horizon search functionality of the AN/SPY-3. A large operating bandwidth is required to mitigate large propagation variations due to meteorological conditions. The system uses commercial off the shelf (COTS) computers and has reduced manning requirements for operation and maintenance. A number of operation and maintenance functions can be completely automated. Commercial IBM Regatta series symmetric multiprocessor (SMP) se ...

Arleigh Burke Class Destroyer
The ''Arleigh Burke'' class of guided-missile destroyers (DDGs) is a United States Navy class of destroyer built around the Aegis Combat System and the SPY-1D multi-function passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, an American destroyer officer in World War II and later Chief of Naval Operations. The lead ship, , was commissioned during Admiral Burke's lifetime. These warships were designed as multi-mission destroyers, able to fulfill the strategic land strike role with Tomahawk missiles; anti-aircraft warfare (AAW) role with powerful Aegis radar and surface-to-air missiles; anti-submarine warfare (ASW) with towed array sonar, anti-submarine rockets, and ASW helicopters; and anti-surface warfare (ASuW) with Harpoon 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 demonstrated capability ...

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kinetic Energy Interceptor
The Kinetic Energy Interceptor (KEI) was a planned U.S. missile defense program whose goal was to design, develop, and deploy kinetic energy-based, mobile, ground and sea-launched missiles that could intercept and destroy enemy ballistic missiles during their boost, ascent and midcourse phases of flight. The KEI consisted of the Interceptor Component (kinetic projectile), the Mobile Launcher Component, and the Command, Control, Battle Management, and Communications (C2BMC) component. On 7 May 2009, the KEI program was canceled due primarily to financial reasons.

DF-21
The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng () is a two-stage, solid-fuel rocket, single-warhead medium-range ballistic missile (MRBM) in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985–86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually. Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. It is thought able to carry a high explosive, submunition, or 300 kt nuclear warhead. The latest DF-21D was said to be the world's first anti-ship ballistic missile (ASBM).
