The rapid growth of the Soviet merchant fleet in the 1970s and early 1980s had not only earned much-needed hard currency, but had also helped to extend Soviet political influence and provide a most valuable auxiliary force to the Soviet Navy. Not the least of its merits was to furnish accurate, comprehensive and up-to-date intelligence of the world’s shipping movements, the cargoes carried, and their destinations. Certain Soviet merchant ships, also, could lay mines, and many were equipped with electronic warfare devices, for both interception and jamming of radio communications. What the Soviets planned to do, therefore, at the outset of hostilities, was to paralyse shipping movement by executing, as nearly as possible simultaneously, a number of operations involving surface raiding forces, submarine attacks, shore-based air attacks, mining by merchant ships, sabotage, radio jamming and disinformation. ‘War zones’, into which non-aligned and neutral shipping would sail at their peril, would be declared in the western approaches to north-west Europe; west of the Straits of Gibraltar; in the Arabian Sea; off the Cape of Good Hope; and in the East China Sea. This concept of the ‘instantaneous threat’ to shipping, rather than the prosecution of a
The Soviet naval and naval air forces available for paralysing shipping, like those allocated for other missions already referred to, had to be in place, or nearly so, long before war contingency plans were executed. Again, therefore, they were bound to be few in number. Western operational intelligence was naturally most interested, in peacetime, in the movements of the Soviet nuclear-powered heavy cruisers of the

It was often assumed, on the Western side, that if war came the
As to submarines in the anti-merchant ship role, only two submarines were kept on station in peacetime with this task in mind. They were both elderly, torpedo-firing nuclear powered boats. One of them patrolled within two days’ easy steaming of the Cape of Good Hope, and the other had a billet within the same distance of Cape de Sao Roque, the focal point off Brazil. It was their job to identify and sink particular ships, designated by Moscow, within hours of the opening of hostilities on the Central Front in Europe.
That, in essence, was the Soviet naval plan. It was a good one, and it very nearly worked.
Admiral Maybury then continued his talk on the basis of the Soviet naval objectives and dispositions already described, with brief accounts of some selected actions, all of which it must be emphasized were taking place at about the same time. He began with the heavy cruiser
