Since that time, an action plan has been developed and agreed with the goal of requiring States to use proven alternatives in new airframe designs beginning in 2009.

Although halons have been phased out in Parties not operating under Article 5 since 1994 and have been significantly reduced in Parties operating under Article 5, halons continue to be used in the aviation industry, both in existing planes and even in the planning of new airframe designs.

Future applications of composite and intermetallic MMCs will be in airframe and skin parts, and advanced turbine engines for future generations of military aircraft as well as in national space planes. Reduced volume costs may lead to a great demand for these materials, especially for automobiles in the next two or three years.

These parameters included a 600 millimetre limit for the diameter of the airframe of all liquid propellant missiles, the prohibition of any modifications of SA 2 missiles relevant to their conversion into a surface to surface mode, the prohibition of tests of SA 2 engines with shut off valves or modified for extended flight duration and the prohibition of the use of original or modified parts and components of SA 2 missiles for use in a surface to surface role.
