The Cold War – Equipment Cost


The Ohio class is a class of nuclear-powered submarines currently used by the United States Navy. The navy has 18 Ohio-class submarines: 14 ballistic missile submarines (SSBN) and four that were later converted to guided missile submarines (SSGN).  The average cost of a Ohio is 2 billion with 50 million per year per sub in operating costs (1996 costs, 1996 dollars). So 50 years at 50 mil per year = 250 mil in operating costs, plus some upgrades (700mil each for an upgrade starting in 2002) and you’re still very short of 7 billion dollars.

All nations expended a substantial proportion of their defence budgets on equipment, and the Cold War was a ‘happy time’ for military men on both sides of the Iron Curtain, even though they constantly complained that they were short of money and starved of resources. The fact was that public funds had never been so generously lavished on military forces in peacetime, and many of the shortages were more apparent than real.

The naval, general and air staffs and the government procurement agencies alike faced many challenges, of which the most fundamental was that, in the worst case, the Third World War might have broken out very suddenly and then been both extremely violent and very short. This would have been quite unlike the First and Second World Wars, where there had been time to mobilize national industries, to develop new equipment, and to produce it all in sufficient quantities. But, whereas those wars had lasted four and six years respectively, the indications were that, in the worst case, the Third World War would have been over in a matter of months, perhaps even of weeks. Such a conflict would therefore have been fought with whatever was available at the time – a ‘come as you are’ war, as it was described at the time. In consequence, armed forces had to be constantly maintained at a state of high readiness, with their weapons, ammunition and equipment to hand – a process which proved difficult to sustain for forty years. A second problem was that the accelerating pace of science and technology, coupled with the lengthy development time for new equipment, meant that many weapons systems were obsolescent before they had even entered service.

Inside their respective pacts, the two superpowers enjoyed many advantages: their financial and industrial resources were huge in comparison to those of their allies, and their own forces were so large that they guaranteed a major domestic market for any equipment that was selected. They thus dominated their partners, and it proved a struggle for their European allies on either side of the Inner German Border to avoid being overwhelmed.

Even for the USA, however, military procurement was by no means smooth sailing. Enormous amounts of money were expended on systems which, for one reason or another, were cancelled before they reached service. One prime example was the effort devoted by the US air force to finding a successor to the Boeing B-52, to maintain its manned strategic bomber force. First there was the XB-70 Valkyrie hypersonic aircraft, which was followed by the B-1, the B-1A (which was virtually a new aircraft) and then the B-2. The sums expended on these aircraft for what was, in the end, very little return are almost incalculable. Further, quite what purpose such aircraft would have served in a nuclear war, apart from dropping H-bombs in gaps left by ICBMs and SLBMs, is not clear. The US army had some dramatic failures, too, such as the Sergeant York divisional air-defence system and the MBT-70 tank.

The US forces were certainly not alone in having problems. The Canadians, who had little enough money for defence, undertook three massive projects, which many contemporary observers warned were over-ambitious. The first was the all-Canadian Arrow fighter of the late 1950s, which reached the prototype stage before cancellation. The second, in the 1980s, was the submarine project which grew from three replacement diesel-electric submarines to twelve nuclear-propelled attack submarines; this reached an advanced stage, though short of orders being placed, before it was cancelled. The third, in the 1990s, was an order for over fifty Westland helicopters to replace ageing anti-submarine and general-purpose helicopters; this was summarily cancelled by a new government, and large compensation payments had to be made. These three projects incurred expenditure totalling hundreds of millions of dollars, but, in the end, there was not a single aircraft, submarine or helicopter to show for any of them.

The British suffered from two problems. The first was projects reaching an advanced stage and then being cancelled. This affected numerous aircraft, such as the Nimrod AWACS, the Vickers-Supermarine Swift fighter and the TSR-2 strike aircraft, while the navy suffered a similar fate with the CVA-01 aircraft carrier, as did the army with the SP70 self-propelled gun and the Blue Water battlefield missile. In addition, some of the projects that did reach service did so only after many years in development and the expenditure of great sums of money, when a viable foreign alternative was readily available at much lower cost.

This is not to deny that some excellent equipment was produced. In the USA, the Los Angeles-class SSNs and aircraft such as the B-52 bomber, F-86 Sabre, F-4 Phantom, F-15 Eagle and F-16 Fighting Falcon were world leaders in their day. Among British successes were the Canberra and Vulcan bombers, the Hunter fighter and the Harrier V/STOL aircraft, the Leander-class frigates and the Centurion tank. The Germans bought most of their aircraft from abroad, but on land their Leopard 1 and Leopard 2 tanks were outstandingly successful. The French produced some outstanding fighter aircraft in the Mirage series, which sold around the world.

Indeed, some European equipment was so good that it even found a market in the United States. The US air force, for example, purchased the British Canberra bomber, while the Marines ordered hundreds of Harrier V/STOL aircraft. In the 1980s the US army bought its most important communications system, RITA, from France, while its tank guns came first from the UK (105 mm) and subsequently from Germany (120 mm).

More Strategic Bombers


Strategic bombers exercised a major influence over the first half of the Cold War, principally because in the 1940s and 1950s they were the only practicable means of delivering the very heavy atomic and hydrogen weapons over intercontinental ranges. Allied to this, bombers had played a major role in the recently concluded Second World War, with the Allied bombing campaigns against Germany and Japan giving the appearance of a war-winning strategy. Indeed, the war had been brought to a close by the two USAAF (United States Army Air Force) B-29 bombers which dropped atomic bombs on Hiroshima and Nagasaki.

There were also bureaucratic reasons for the fierce advocacy of the bomber, however. The US air force finally became independent of the US army in 1947 and was extremely keen to prove itself to be the war-winning arm in the Cold War. In the UK, which found itself facing the reality that it was now only the second most powerful nation in the West, membership of the exclusive ‘nuclear club’ appeared to be the only way to retain superpower status, and, in the short term, bombers were the only feasible way of achieving that. On the Soviet side, the air force realized that it had never produced a bomber force to match those of the USA and UK, and was desperate to rectify this. Thus, from 1945 into the mid-1960s, the strategic bomber armed with nuclear weapons was the symbol of global power.

Atomic warfare was associated with aviation from the very beginning. The first and last nuclear weapons ever used in anger were dropped by U. S. B-29 bombers in August 1945 on the Japanese cities of Hiroshima and Nagasaki. These actions represented the end of World War II (Japan soon surrendered) and the beginning of the Cold War (erstwhile allies aligned against one another). As postwar tensions mounted, the United States clung to its monopoly on atomic weapons as its trump card in any future conflict. In the late 1940s and early 1950s, the U. S. Air Force developed the newly created Strategic Air Command into an elite force of medium- and long-range bombers capable of delivering nuclear weapons to targets throughout the Soviet Union, a strategy of massive retaliation in the event of war with the communist nation. Though the Soviet Union tested its first atomic bomb in 1949-years earlier than expected-the United States remained well ahead in its capacity for nuclear attack throughout the 1950s. In the early 1950s, the superpowers added thermonuclear weapons to their arsenals; some explosive yields were 1,000 times more powerful than early atomic bombs. By the mid-1950s, it had become possible to kill an entire nation in a matter of days. U. S. military planners hoped their nuclear superiority would deter any war, but should it come they continued to believe they could “win” a nuclear exchange by undertaking a massive first strike, thereby preventing Soviet retaliation.

The study of German jet engines helped the Soviets develop their first jet fighters (in 1946, the MiG-9 and Yak-15 were introduced). At the same time, Soviet designers benefited from the wartime acquisition of several U. S. B-29 bombers. The strategic bomber force was reorganized in 1946 within the Soviet Air Force, equipped with Tu-4 heavy bombers (based on the B-29 design) and Il-28 medium bombers.

The progress of the Cold War since the 1960s, the development of nuclear, thermonuclear, and missile weaponry, as well as the development of entirely new technologies, prompted significant changes in the Soviet Air Force. The political and military leadership needed a world-class airpower to back up rising global ambitions and be able to participate in any number of contingencies-nuclear and conventional. At the same time, the greater emphasis on ICBMs in the development of strategic power allowed the Soviets to reduce a number of obsolete aircraft without lowering the combat capability of its air force.

From the 1960 to the 1980s, the Soviets modernized their fleet of strategic bombers and introduced the supersonic Tu-22 bomber (1963). Beginning in 1987, the Tu-160 strategic bomber entered service. This bomber force was an integral (although the smallest) part of the Soviet strategic triad. Additionally, air-to-surface cruise missiles enhanced the strategic function of these aircraft. The cruise missiles, as well as the introduction of the Tu-26 longer-range bomber, in 1974 gave the Soviet Air Force the ability to carry out deep strikes across Western Europe, the North Atlantic, and North America.

STAND-OFF MISSILES
Bomber designers and the tacticians fought an unending war against the potential defenders in an effort to ensure that the bomber would get through to its targets. In the late 1940s the major threat came from radar-directed anti-aircraft guns, which had reached a considerable degree of sophistication, and the bombers’ first response was simply to fly higher than the effective ceiling of the guns. The next threat was air-defence fighters, and here again the bombers responded by flying higher and faster – there were numerous reports of British and US reconnaissance flights over the USSR in the early 1950s in which the Soviet fighters simply could not reach the same altitude as the intruder.

Second World War bombers were fitted with machine-guns in a variety of positions – including the nose, the waist, above and below the fuselage, and the tail – but these were rapidly reduced to just the tail, the elimination of the others saving considerable weight and enabling the aircraft to fly higher and faster. Also in the Second World War, bombers had been escorted by fighters, particularly on the USAAF’s daylight raids; but the strategic ranges now being flown were far in excess of anything a fighter could undertake. So in the 1950s the US air force trialled the idea of the B-36 bomber taking a fighter with it, with the latter being carried on a retractable cradle from which it could be launched in mid-air to deal with enemy fighters, then being recovered for the return to base. A special miniature fighter, the McDonnell XF-85 Goblin, was tested, as was the RF-84K, a modified version of the full-size F-84 Thunderjet fighter, but, although launching proved feasible, recovery did not, and the idea was not pursued.

Electronic countermeasures (ECM) were always used, becoming increasingly sophisticated as time passed. Thus electronic jamming was used to confuse enemy radars, as was ‘chaff’ (strips of metal foil cut to the wavelength of the radar), which was dropped in large quantities, either by the bomber or by specialized escorting aircraft.

One of the earliest devices to help the bomber get through was the US air force’s ADM-20 Quail, which resembled a miniature unmanned aircraft and was dropped over enemy territory, where it flew for some 400 km, using its on-board ECM devices to confuse the enemy as to the strength, direction and probable targets of the incoming bomber force. A maximum of three Quails could be carried by a B-52, and the device was in service from 1962 to 1979.

The main emphasis then turned to stand-off missiles – a concept which, like so many others, had its genesis in Germany, where V-1 missiles had been launched from Heinkel He-111 bombers in 1944–5. The Cold War missiles carried a nuclear warhead and were designed to be launched from the bomber while still outside the range of the enemy air defences. One of the first was the US Hound Dog – a slim missile with small delta wings, and powered by a turbojet – which entered service in 1961. Two Hound Dogs, each with a 1 MT nuclear warhead, were carried beneath the wings of a B-52. The missile could be set to fly at any height between about 50 m and 16,000 m, and had a range at high level of 1,140 km, less at low level. The guidance system was capable of high- or low-level approach, with dog-legs and jinxes to confuse the defence.

Next came the unhappy saga of Skybolt, which was an attempt to use a bomber to launch a ballistic missile, which would have given longer range and, of greater importance, a much shorter flight time. The UK air force joined the project, but the incoming Kennedy administration unilaterally cancelled it in December 1961 – greatly to the indignation of the British, who used the issue as a lever to obtain Polaris missiles and SSBN technology to replace its V-force bombers.

The Short-Range Attack Missile (SRAM), which entered service in 1972, was a rocket-propelled missile with a 170 kT nuclear warhead and a speed of Mach 3. SRAMs could fly either a semi-ballistic, a terrain-following or an ‘under-the-radar’ flight profile, the latter terminating in a pull-up and high-angle dive on to the target. The range depended on the height, and was from 56 km at low level to 170 km at high level. B-52s normally carried twenty SRAMs, while the FB-111A carried six and the B-1B twenty-four.

The Air-Launched Cruise Missile (ALCM) entered service with the US air force in 1982. This weapon had folding wings which extended when it was dropped from the carrier aircraft, and was powered by a small turbojet engine. Designed exclusively for low-level flight, the ALCM used a radar altimeter to maintain height and a map-matching process known as terrain comparison (TerCom) to give very precise navigation. The nuclear-armed version (AGM-96B) had a 200 kT warhead, a CEP of 30 m and a range of some 2,500 km. The AGM-96C was conventionally armed, with a high-explosive warhead, and this version demonstrated its effectiveness and accuracy when thirty-five were launched by B-52s during the Gulf War. B-52s could carry up to twelve and B-1Bs twenty-four.

Soviet stand-off missile development followed a similar pattern and time-scale, although in the early stages of the Cold War the missiles tended to be much larger and less effective than their US counterparts. Indeed, the first missile designed for use by strategic bombers, the AS-3 (NATO = ‘Kangaroo’) remains the largest air-launched missile to go into service, with a length of some 15 m, a wingspan of 9 m and a weight of 11,000 kg; only one could be carried by a Tu-95 (Bear-B). It did, however, have a useful range (650 km) and a high speed (Mach 2), and with an 800 kT warhead it was targeted against large area targets such as cities and ports.

The AS-15 (NATO = ‘Kent’) was much smaller and generally similar in size, performance and role to the US Tomahawk; sixteen could be carried by the Tu-95 Bear-B and twelve by the Tu-160 Blackjack. It carried a 200 kT nuclear warhead and flew at high subsonic speeds over a range of some 3,000 km at a height of 200 m, with an accuracy (CEP) of 150 m.

The most dramatic bomber to serve with SAC was the tailless, delta-winged Convair B-58, with a Mach 2 speed and 8,250 km range. Air-to-air refuelling enabled the B-58 to undertake long flights (e.g. from Tokyo to London), loudly advertising its wartime capabilities. The aircraft used a unique system in which a large pod under the fuselage housed both the nuclear weapon and the fuel for the outward flight; it was dropped complete, enabling the aircraft to make a very rapid getaway before returning to base on its internal fuel supply. Although generally successful, the B-58 was very expensive to operate, even by US standards, and was retired after just ten years’ service, without replacement.

In 1969 US satellites began to return photographs of a new Soviet bomber on the apron at the new aircraft factory at Kazan. This turned out to be a swing-wing version of the Tupolev Tu-22, designated Tu-22M (NATO = ‘Backfire’). Subsequently, a virtually new aircraft with some external similarities to the Tu-22M appeared and was put into production as the Tu-26 (NATO = ‘Backfire-B’). (The relationship between the Tu-22M and the Tu-26 was probably similar to that between the American B-1A and B-1B.)

Three versions of the Tu-26 entered service, one of which carried nuclear weapons for use in the land-attack role. There were, however, repeated arguments between the United States and the Soviet Union over the role of this bomber, with the former stating and the latter denying that it was a strategic bomber. This became a major issue in the SALT II negotiations, and President Brezhnev eventually ordered that the aircraft’s flight-refuelling probes be removed to prove that it did not have the ability to reach the USA, although since these could have been replaced in less than thirty minutes this was only a token gesture. The Tu-26 entered service in the mid-1970s and was produced at the rate agreed under SALT II – thirty per year – with service numbers peaking at about 220.
