when was the original m72 law first produced
M72 LAW The M72 LAW (Light Anti-Tank Weapon, also referred to as the Light Anti-Armor Weapon or LAW as well as LAWS Light Anti-Armor Weapons System) is a portable one-shot 66-mm unguided anti-tank weapon. The solid rocket propulsion unit was developed in the newly formed Rohm and Haas research laboratory at Redstone Arsenal in 1959,[5] then the full system was designed by Paul V. Choate, Charles B. Weeks, Frank A. Spinale, et al. at the Hesse-Eastern Division of Norris Thermadore. American production of the weapon began by Hesse-Eastern in 1963, and was terminated by 1983; currently it is produced by Nammo Raufoss AS in Norway and their subsidiary Nammo Talley, Inc. in Arizona.[6]
First law of thermodynamics The first law of thermodynamics was developed empirically over about half a century. The first full statements of the law came in 1850 from Rudolf Clausius and from William Rankine; Rankine's statement is considered less distinct relative to Clausius'.[2] A main aspect of the struggle was to deal with the previously proposed caloric theory of heat.
