In the past a performance of the Russian armaments' industry was a continual source of surprise to experts. It was obvious that apart from civilian industry there must be areas where important technological expertise had been created and built up. Since 5 years, conversion of military enterprise has been the principal topic of numerous conferences and studies. State institutions and international organisations can promote and accelerate the exchange of information and the restructuring process. However, the success of this process ultimately depends on how the economy will accept this change and how far market economy forces-can develop it.The NATO Advanced Research Workshop "Conversion of Military Enterprises in Russia- A Practical Approach of Industry and Science" was an excellent possibility for all participants from NATO-countries and from Russia, Ukraine and Belarus to discuss experiences and results after 5 years of reform period, All participating scientists noticed this aspect was proud to participate in this NATO event.
