offset this it became necessary to increase drastically the yield of the warheads. But this was not the most important consideration. The fundamental reason was that a thermonuclear charge, whatever its yield, needs only one nuclear detonator. The shortage of uranium and plutonium made it necessary to produce a comparatively small quantity of thermonuclear warheads and to compensate for this by increasing their yield.
The Soviet Union has put a lot of work into the problem of producing a thermonuclear warhead in which reaction is brought about not by a nuclear detonator but by some other means-for instance, by the simultaneous explosion of a large number of hollow charges. This is very difficult to achieve, for if just one charge functions a thousandth of a second early, it will scatter all the others. American electronic equipment is needed to solve the problem high precision timers, which will deliver impulses to all the charges simultaneously. There are some grounds for believing that timers of this sort may be sold to the Soviet Union and, if this happens, the SRF will acquire titanic strength. Meanwhile, not all Soviet rockets have warheads. There are not enough for every rocket, so that, at present, use is being made of radioactive material which is, quite simply, waste produced by nuclear power stations-radioactive dust. Rather than launch a rocket without a warhead, the wretched thing might as well be used to scatter dust in the enemy's eyes… Naturally, scattering small quantities of dust over wide areas of enemy territory, even if it is highly radioactive, will not do much damage and it will certainly not decide the outcome of a war. But what can one do if one has nothing better?
However, naturally, the SRF must not be underestimated. Rapid technical progress is being made and Soviet engineers are skilfully steering a course between the technological icebergs which confront them, sometimes achieving astounding successes, brilliant in their simplicity.
The technical balance could change very quickly, if the West does not press forward with the development of its own equipment as quickly and as decisively as the Soviet Union is doing.
The National Air Defence Forces
The National Air Defence Forces (ADF) are the third most important of the five Services which make up the Soviet Armed Forces, after the Strategic Rocket Forces and the Land Forces. However, we will examine them at this point, directly after the SRF, since like the latter they represent not simply an administrative structure but a unified, controlled combat organisation, subordinated directly to the Supreme Commander. Because they form a unified combat organisation, the ADF are always commanded by a Marshal of the Soviet Union. The Land Forces, which are five times the size of the ADF, and which represent the striking force of the Soviet Union in Europe, are headed only by a General of the Army.
In the armed forces of any other country, responsibility for air defence is laid upon its air forces. In the Soviet Union, the air defence system was so highly developed that it would be quite impossible to confine it within the organisational structure of the Air Forces. Moreover, the ADF are the third most important Service while the Air Forces occupy fourth place.
The independence of the ADF from the Air Forces is due not only to their size and to their technical development, but also to the overall Soviet philosophy concerning the allocation of wartime roles. In any country in which Soviet specialists are given the task of setting up or restructuring the armed forces, they establish several parallel systems of air defence. One is a static system, designed to defend the territory of the country and the most important administrative, political, economic and transport installations which it contains. This is a copy of the ADF. In addition, separate systems for self-defence and protection against air attack are set up in the land forces, the navy and the air force.
While the national defence system is static, those of the different armed services are mobile, designed to move alongside the forces which they exist to protect. If several systems find themselves operating in the same area, they work with one another and in such a case their collaboration is always organised by the national system.
The division of the ADF into a national system and another system for the protection of the armed services, took place long before the Second World War. All anti-aircraft artillery and all searchlight and sound-ranging units were divided between those under the command of army and naval commanders and those covering the most important civil installations, which are not subordinated to army commanders but had their own control apparatus. The fighter aircraft available were divided in the same way. In 1939, for instance, forty air regiments (1,640 combat aircraft) were transferred from the strength of the Air Forces to that of the ADF, for both administrative and combat purposes. Mixed ADF units were formed from the anti-aircraft artillery, searchlight and air sub-units, which succeeded in cooperating very closely with one another.
During the war the ADF completed their development into a separate, independent constituent of the Armed Forces, on an equal footing with the Land Forces, the Air Forces and the Navy. During the war, too, the development of fighter aircraft designed specifically for either the Air Forces or the ADF was begun. Flying training schools were set up to train ADF pilots, using different teaching programmes from those of the Air Forces. Subsequently, anti-aircraft gunnery schools were established, some of which trained officers for anti-aircraft units of the Land Forces and Navy while others prepared officers for the anti-aircraft units of the ADF. After the war, the teams designing anti-aircraft guns for the Armed Forces were directed to develop especially powerful anti-aircraft guns for the ADF.
At the end of the war the total strength of the ADF was more than one million, divided into four ADF fronts (each with two or three armies) and three independent ADF Armies.
After the war the ADF was given official status as an independent Armed Service.
Today the ADF has more than 600,000 men. For administrative purposes they are divided into three arms of service:
ADF Fighter Aviation
ADF Surface-to-air Missile Forces
ADF Radar Forces
For greater efficiency and closer cooperation, the sub-units of these three arms of service are brought together to form mixed units-ADF Divisions, Corps, Armies and Fronts (in peacetime Fronts are known as ADF Districts).
The fact that 3,000 combat aircraft, among them some of the most advanced, have no operational, financial, administrative or any other connection with the Air Forces, has not been grasped by ordinary individuals in the West, nor even by Western military specialists. It is therefore necessary to repeat, that the ADF rate as a separate and independent Armed Service, with 3,000 supersonic interceptor aircraft, 12,000 anti-aircraft missile launchers and 6,000 radar installations.
It is because the ADF are responsible both for the protection of Soviet territory and of the most important installations in the USSR that they function independently. Since they are concerned mainly with the defence of stationary targets, the fighter aircraft developed for them differ from those with which the Air Forces are equipped. The ADF are also equipped with surface-to-air missiles and radar installations which differ from those used by the Land Forces and by the Navy.
The Air Forces have their own fighter aircraft, totalling several thousand. The Land Forces have thousands of their own anti-aircraft missile launchers, anti-aircraft guns and radar installations. The Navy, too, has its own fighters, anti-aircraft missiles and guns and radar, and all of these belong to the individual Armed Service rather than to the ADF, and are used to meet the requirements of the operational commanders of the Land Forces, Air Forces and Navy. We will discuss these independent air defence systems later; for the moment we will confine ourselves to the national defence system.
The fighter aircraft of the ADF are organised as regiments. In all, the ADF has more than seventy regiments, each with forty aircraft.
The ADF cannot, of course, use fighter aircraft built for the Air Forces, any more than the latter can use
