A kugelblitz (German: [ˈkuːɡl̩ˌblɪt͡s] ⓘ) is a theoretical astrophysical object predicted by general relativity. It is a concentration of heat , light or radiation so intense that its energy forms an event horizon and becomes self-trapped.
Topol-M launch from silo. A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs).
Deployment of the Minuteman ICBM began in 1961 with the initiation of construction of 150 silos and associated launch control facilities. Activation of the 44th Strategic Missile Wing on 1 January 1962, marked the initiation of SAC's first LGM-30B Minuteman I wing (the 341st SMW was equipped with the Minuteman 1A). The assignment of the 66th ...
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.
Kugelblitz (German for "ball lightning") may refer to: Kugelblitz (armoured fighting vehicle) , a German self-propelled anti-aircraft gun used in World War II Kugelblitz (astrophysics) , a concentration of light so intense that it forms an event horizon and becomes self-trapped
"Kugelblitz" model, showing gun elevation. The Kugelblitz combined the chassis and basic superstructure of the Panzer IV tank with a newly designed oscillating turret. This turret was fully enclosed, with overhead protection and 360° traverse. Mass production was planned, but never happened due to the disruption by Allied bombing efforts. [2]
The silo, known as launch facility Delta Nine (D-09) was constructed in 1963. It occupies 1.6 acres (6,000 m 2) nearly one-half mile (800 m) southwest of Interstate 90 at Exit 116 and six miles (9.7 km) from the town of Wall, South Dakota, in eastern Pennington County. It consists of an underground launch tube ("missile silo") 12 feet (3.7 m ...
Browns Ferry Unit 1 drywell and wetwell under construction, within a Mark I containment. BWR Type 4 (BWR-4, BWR/4): Introduced in 1966, 1100 MW (Browns Ferry 1–3). Largely similar to the BWR/3 in design with an identical recirculation system, but power density was increased by 20%. [5] Available with either Mark I or Mark II containment.
