Munitions binary

Reactive materials are solids that produce arsine on contact with moisture or acids. Binary munitions that mix these reactive materials with water or acid upon delivery have been developed.

The term unitary indicates a single chemical loaded in munitions or stored as a lethal material. More recently, binary munitions have been produced in which two relatively safe chemicals are loaded into separate compartments to be mixed to form a lethal agent after the munition is fired or released. The components of binary munitions are stockpiled in separate states. They are not included in the present CSDP, but they are being destroyed in a separate program.

The chemistry illustrated in equation 17 was developed to meet the requirements of the binary weapons system. In the absence of base, the reaction of an alcohol with methylphosphonic difluoride (11) is slow and requires heating to drive to completion. In the presence of an amine, the reaction is extremely rapid and exothermic and proceeds in good yield. For the (US) binary munitions system for sarin, a mixture of propan-2-ol and isopropylamine are brought together with methylphosphonic difluoride when the separate canisters containing the reactants are ruptured as a result of the shock caused by firing the munition. The chemical reaction occurs within the time of flight of the munition ". ... 

OR) (Carnes 1989 Army Chemical Materials Agency at www.cma.army,mi ). "Unitary munitions are loaded with undiluie, finished CW agent, as opposed to binary munitions, in which agent precursors mix and react to form finished agent after the munition is fired. 

In 1981, the secretary of defense issued a memorandum to proceed to acquire binary chemical bombs. The appropriation restrictions of 1976, however, blocked procurement of binary munitions for several more years. The next step came in 1985 when the U.S. Congress passed Public Law 99-145 authorizing production of chemical weapons. The final step came in 1987, when President Reagan certified to congress that all their conditions had been met to start production of binary chemical weapons.3... 

Binary munitions are those in which the chemical substances are held in separate containers and react when mixed or combined. This may happen during firing, launching, or by other initiation methods. The product is a chemical agent or material agent. Binary components must be tested for individually because in a burial situation they may not be combined. Care must be taken not to mix chemical agents found at post-World War II sites (i.e., compositing soil samples). 

Binary munitions developed from a logical idea where the final step in the synthesis of a chemical agent was the simple combination of two ingredients. Where these final two compounds served to facilitate storage and handling (i.e., liquid, noncorrosive), it was not difficult to conceptualize a weapon where the constituent chemicals are separated. 

Unitary munitions may take the form of a shell, rocket, bomb, or canister filled with the CW agent, and only a fuse needs to be added before firing. Flowever, unitary munitions are dangerous to store, handle, and transport. Binary munitions, which are generally considered a significant improvement in design, reduce the likelihood of serious accidents, especially if the two components are kept apart until the last possible moment. The US 155-mm artillery munition utilized a binary system that combined the precursor chemicals difluor (p-p) and isopropyl alcohol to produce sarin. 

A number of similar reports appeared in the media and in influential military and technical journals. The problems were sometimes discussed with more sophistication, but the basic message remained the same the Soviet CW capability threatened NATO. The best way to deter the Soviet Union from initiating CW was by the possession of a modernised retaliatory capability which, for reasons of safety and flexibility, should be composed of binary munitions. 

This was a clear invitation to the European Allies to take steps to provide their own chemical weapons compliance with the requirement would have drawn NATO into a highly embarrassing controversy without any concrete results. It was deleted when the Defense Authorization Act was again amended in December. The final version of the Act required the President to certify that the North Atlantic Council had formally adopted a Force Goal stating the requirement for modernization of the US proportional share of the NATO chemical deterrent with binary munitions. . 

Article II covers definitions and criteria . The term chemical weapons is to apply to toxic, lethal, super-toxic and harmful chemicals including key precursors, except where they are intended for purposes not prohibited by the Convention as long as the types and quantities involved are consistent with such purposes . It also embraces munitions and devices specifically designed to cause death or other harm by releasing toxic chemicals. Further work remains to be done on this article to cover the position of riot control agents, chemicals which, although not toxic in themselves, could be used to increase the effect of chemical munitions, and the definitions relating to binary munitions.
