Submarines were a different matter. Leaving aside for the moment the strategic nuclear ballistic missile-armed, nuclear-powered submarines (SSBN), the Soviets had produced three main types of attack, or general purpose, sometimes called ‘fleet’, submarines. One of these types was nuclear powered and armed with torpedoes and missiles, for both anti-surface ship and ASW purposes. The other two types were armed with anti-ship cruise missiles, one being nuclear powered and the other diesel-electric driven. Within each type there were several classes, the most modern of which could run quietly and deep. In addition, the Soviet submarine fleet included a large number of diesel-electric ‘patrol’ submarines, torpedo armed and capable, as an alternative, of laying mines. Unlike the nuclear-powered submarines, the diesel-electric ones were bound to expose an air induction tube above the sea surface when charging the battery, and this could be detected by radar, especially airborne radar. On the other hand, these submarines were so quiet when submerged that they were extremely difficult to detect by passive means, and active sonar had therefore to be used against them. Active sonar, however, could act as a beacon for nuclear-powered submarines, which were able to proceed at high speed from a distance, closing to missile-firing range while still remaining undetected. They were able to operate in the ocean depths anywhere in the world for as long as the food and the weapons lasted, but they could not safely or effectively operate in the shallow water (200 metres or less) which covers the Continental Shelf. This factor apart, there can be no doubt that the Soviet submarine force posed a severe threat to the warships and shipping of the United States and its maritime allies in being probably able to achieve a successful attack, in the face of the best anti-submarine measures which could be taken, at least once in every three attempts, while on average only one submarine would be destroyed in every five that were detected and classified as a submarine contact.
Soviet naval aviation, on the other hand, had by 1985 hardly come of age. The first nuclear-powered, large aircraft carrier had not yet completed her trials. The four 45,000-ton
An assessment of the Soviet amphibious forces indicated that, despite the well-advertised excellence of their naval infantry, they seemed to lack certain important elements, such as vertical airlift and integral tactical air support. For the intervention role, against light opposition, the force had to be reckoned with, but it could not compare in combat power with the US Marines. Another relatively weak aspect of the Soviet naval forces was in logistic support. There was only a small capacity for under-way replenishment of major fleet units. In peacetime, it was true, forces such as the Fifth
