American manufacturing technlaiiea are believed to be known to the Soviet a, and the fact that Sveden and other aoropean countries hare developed sophlfltlcated fuzen leads to the conclusion 'that the Soviets probably have developed and produced similar nWV

The Soviets have all information necessary for tbe development of BOM. They have used "window" la the past, and this and elallar reflection devices will almost certalnlj be encountered la the future. In addition, electronic Jamming will, probably be enoowntered at all freeuenolea up to thareglea by

Inadequacies in present eeulp-ment may be offset by effective coordination of ths network; such an extensive coordination network has already been established to control the Toice of Awerlea Jamming program.
