AFAIK.
Correct. NATO is simply on the distribution list. ASCC (Air Standardization Coordinating Committee) was formed in 1948 with US, UK and Canada. Australia and New Zealand joined later. ASIC (Air and Space Interoperability Council) took over from ASCC during 2005. ASIC then transitioned into AFIC (Air Force Interoperability Council) and now Five Eyes AFIC.
