Intercontinental ballistic missile ICBM

The special needs of the space program motivated the search for composite materials for other reasons also. For example, during tests of the first Atlas ICBM (intercontinental ballistic missile), engineers were concerned that the rocket s metallic components would not survive the missile s reentry into the atmosphere they feared it would melt down because of the intense heat to which it was exposed. By the late 1950s, therefore, aerospace researchers had begun to look for satisfactory substitutes for metal alloys for such applications. With that research, the modern held of composite design was horn. One of the first composites tested consisted of pieces of glass embedded in melamine, purported to be the first composite material developed for aerospace applications.

Post-WWII. After WWII most LP R D shifted from Germany to the USA and the USSR. Technical progress since 1945 in LP for rockets can be characterized by a host of minor improvements rather than major advances, and some spectacular applications of LP in rockets for military use and for space exploration, eg, in ICBM s (Intercontinental Ballistic Missiles) and in USA USSR Moon, Mars Venus shots . Thus the major developments since WWII have been primarily in the application of existing, though improved, propulsion systems to such highly publicized rockets as Sputnik, Vanguard, Soyuz, Saturn, Vostok, Apollo, Explorer, etc...

After the war Hercules returned to the production of commercial explosives as well as military propellants and continued to build on its cellulose and naval stores capabilities. In 1958 its explosives department created a chemical propulsion division to develop propellants for missiles and space vehicles. In 1959 it received contracts from the U.S. Air Force to develop new solid-fuel rocket motors and subsequently produced the motor for the third stage of the nation s first solid-fuel intercontinental ballistic missile (ICBM), the Minuteman. Hercules played an even larger role in the development of the Navy s submarine-launched Polaris ICBM. With cellulose came new specialties, including synthetic resins and paper chemicals, as well as carboxymethylcellulose (CMC), an intermediate used in the production of foods, pharmaceuticals, and cosmetics. From naval stores came other new specialty chemicals and an effective insecticide, toxaphene, and other agricultural chemicals.3... 

Mike Hocker from Poughkeepsie, New York, suggested that the use of atomic weapons on Infinity World would be less of a concern. Mike believes that wars would be common as populations tried to destroy others before they were destroyed. Xenocide and paranoia would be the geopolitical norm. Nations would race to develop interworld ballistic missiles (IWBMs) as opposed to intercontinental ballistic missiles (ICBMs). Vast land areas would be radioactive or devastated by horrendous nuclear, chemical, and biological weaponry. 

Oddly enough, it was more the concern with unmanned systems, the intercontinental ballistic missiles (ICBMs), that led to the development of the system safety concept [p. 4]. 

Most agree that one of the first major formal system safety efforts involved the Minuteman intercontinental ballistic missile (ICBM) program. A series of pre-Minuteman design-related silo accidents probably provided at least part of the incentive (U.S. Air Force 1987).

We evaluate our architecture in the context of a BMD demonstration. In November 2009, MIT Lincoln Laboratory demonstrated a proof-of-concept net-centric BMD decision-support system during the simulation of an intercontinental ballistic missile (ICBM) attack [10]. For this exercise, we developed and deployed an illustration-of-concept implementation of om siu vivability architecture. This exercise demonstrated the principles of om siu vivability architecture in a realistic simulation of a coordinated ICBM and cyber attack. Our experience developing this survivabihty architecture taught us several important lessons learned, which we share in this paper. 

FTA was originally developed in 1962 at Bell Laboratories, under a U.S. Air Force Ballistics Systems Division contract to evaluate the Minuteman I Intercontinental Ballistic Missile (ICBM) Launch Control System [2]. This method is widely used in the area of safety engineering, to quantitatively determine the probability of safety in an undesired or accidental event referred to as a top event. With reference to Fig. V/3.0-1A, at the beginning of the chapter the importance of boundaries is discussed. In the figure, there is some gap between the external boundary and actual problem part (actual problem boundary). This is the interface part, and is quite important in any risk analysis. In the case of FTA, it is also important to define limits of resolution. A system is usually divided into subsystems, and in some cases a part may be subdivided into smaller parts. Now, the smallest part determines the limit of resolution and internal boundary. If, in one case, fault level is to be determined up to card level, and in another case it is necessary to determine the fault up to component level, naturally in the latter case, resolution will be higher. Limit of resolution has been shown in Fig. V/3.0-1A.
