Emergency Rocket Communications System
The Emergency Rocket Communications System (ERCS) was designed to provide a reliable and survivable emergency communications method for the United States National Command Authority, using a UHF repeater placed atop a Blue Scout rocket or Minuteman II intercontinental ballistic missile. ERCS was deactivated as a communication means when President George H.W. Bush issued a message to stand down SIOP-committed bombers and Minuteman IIs on 27 September 1991. Headquarters SAC was given approval by the Joint Chiefs of Staff to deactivate the 494L payloads beginning 1 October 1992. However, Headquarters SAC believed it was inefficient and unnecessary to support ERCS past fiscal year 1991, and kept the accelerated deactivation schedule. Mission The mission of the Emergency Rocket Communications System was to provide assured communication to United States strategic forces in the event of a nuclear attack. ERCS was a rocket or missile that carried a UHF transmitter as a payload inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Launch Control Center (ICBM)
A launch control center (LCC), in the United States, is the main control facility for intercontinental ballistic missiles (ICBMs). A launch control center monitors and controls missile launch facilities. From a launch control center, the missile combat crew can monitor the complex, launch the missile, or relax in the living quarters (depending on the ICBM system). The LCC is designed to provide maximum protection for the missile combat crew and equipment vital to missile launch. Missile silos are common across the midwestern United States, and over 450 missiles remain in US Air Force (USAF) service. Due to modern conventional weapons, missile launch control centers are becoming rarer in the US, and it is expected that the number of missiles will stay at 450 Minuteman III. General information All LCCs are dependent on a ''missile support base'' (MSB) for logistics support. For example, Minot AFB is the MSB for the 91st Missile Wing. Three types of Minuteman LCCs exist: # Alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whiteman Air Force Base is a United States Air Force base located just south of Knob Noster, Missouri, United States. The base is the current home of the B-2 Spirit bomber. It is named for 2nd Lt George Whiteman, who was killed during the attack on Pearl Harbor. History World War II In 1942, the U.S. Army Air Corps selected the site of the present-day base to be the home of Sedalia Glider Base, a training base for WACO glider pilots. In May 1942, construction workers began building a railroad spur for the new air base in an area known to locals as the "Blue Flats" because of the color of the soil. The new railroad line was built by the Missouri Pacific Railroad. The base was officially opened on 6 August 1942. On 12 November 1942, the name was changed to Sedalia Army Air Field. After the end of World War II, operations at the airfield declined, and many of the buildings were abandoned. In December 1947, the base was put on inactive status. 340th Bomb Wing In August 1951, the ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaig ...

Milstar
Milstar (Military Strategic and Tactical Relay) is a constellation of military communications satellites in geosynchronous orbit, which are operated by the United States Space Force, and provide secure and jam-resistant worldwide communications to meet the requirements of the Armed Forces of the United States. Six spacecraft were launched between 1994 and 2003, of which five are currently operational; the third launch failed, both damaging the satellite and leaving it in an unusable orbit. History Milstar Block I spacecraft, or Milstar Developmental Flight Satellite (DFS)-1 and -2, were designed with a Low Data Rate (LDR) payload in the wing of the satellite that broadcast in the Super High Frequency (SHF) and Extremely High Frequency (EHF) ranges, and also a classified communication payload in the wing. The DFS-1 satellite was launched on 7 February 1994 aboard the first Titan IV(401)A rocket, but with the classified wing payload deactivated. It was followed by the D ...

Federation Of American Scientists
The Federation of American Scientists (FAS) is an American nonprofit global policy think tank with the stated intent of using science and scientific analysis to attempt to make the world more secure. FAS was founded in 1946 by scientists who worked on the Manhattan Project to develop the first atomic bombs. The Federation of American Scientists aims to reduce the amount of nuclear weapons that are in use, and prevent nuclear and radiological terrorism. They hope to present high standards for nuclear energy's safety and security, illuminate government secrecy practices, as well as track and eliminate the global illicit trade of conventional, nuclear, biological and chemical weapons. With 100 sponsors, the Federation of American Scientists says that it promotes a safer and more secure world by developing and advancing solutions to important science and technology security policy problems by educating the public and policy makers, and promoting transparency through research and ...
