The difficulty lay in knowing how to sustain operations without technical facilities and logistic stocks. To ease the problem the airmen’s eyes had been resting on the civilian helicopter fleet which had grown to more than a hundred aircraft around the North Sea oil industry. The operating companies were very willing to play their part in national plans and readily agreed to a scheme, in emergency, of attaching up to four of their aircraft to each of the main RAF and USAF bases so as to form a logistic chain to the newly earmarked satellite airfields. The plan was exercised a few times before the war and when the real need came the civilian helicopter crews performed herculean tasks in ferrying technicians, weapon reloads, test equipment and spare parts. They did this by day and by night without regard to weather, often plying between airfields under missile attack. Hardened air crew that they were, some were heard to comment, with a nice taste for understatement, that it was quite relaxing after the rigours of flying to the North Sea rigs in winter.
A signal success came to these helicopters in the first days just before and after the outbreak of war as the ‘air bridge’ was swung across the Atlantic and US Boeing 747s and Lockheed C-5s were landing up to 300 troops in central England every four minutes. The commercial helicopters ferried thousands of troops and hundreds of tons of their supplies from the airfields to the railheads and east coast ports. This eased what threatened to become an unmanageable congestion on the roads and railways and cut vital hours off the reinforcement time from the United States to the continent of Europe.
None the less, what the Commander Allied Air Forces Central Europe (COMAAFCE) had described in 1982 as ‘the Achilles heel’ of his Command, the insufficient availability of stocks of fuel, ordnance, spares and other requirements on dispersal airfields, continued to give concern. Co-located operational bases (COB), from which both USAF and RAF aircraft could operate, alleviated the difficulty. It was never quite to disappear. The danger that reinforcement aircraft, together with those withdrawn from further forward, would arrive in such numbers as to swamp support facilities remained.
First priority in the British dispersal plan went to the large air tankers, the AEW aircraft, and the Nimrod anti-submarine patrol aircraft, all of which had key roles but existed only in small numbers. They were anyway far too big to be protected in the hardened shelters which had been built with NATO common funds at most of the operational airfields; but the smaller RAF aircraft like the Tornados, Buccaneers and Jaguars, as well as the Hawk jet-trainers in their secondary air-defence role, were also thinned out and sent to the dispersed sites when it looked as if the main bases might become too hot to hold them.
By 1984 British Airways Boeing 757s had been modified to carry out refuelling which was to be invaluable when the almost insatiable demand for air tanking started in the first hours of the war. Sadly a proposal by British Airways in the late 1970s that their new jumbo-jet cargo carriers should be built with floors strengthened for military loads got bogged down in a bureaucratic argument about who would pay for the airline’s payload penalty in peacetime. The Western allies were in consequence denied a very badly needed addition to their airlift for military vehicles.
And so it was that in these sorts of ways, and with a very free exchange of ideas within NATO, the Allied air forces made the best of the seven lean years before the war. But while their attention was turned to improving current effectiveness, rather than to bidding for solutions in the future, technology and its opportunities were of course not standing still.
The airborne warning and control system (AWACS) was arguably the biggest ‘force multiplier’ of any recent developments and its impact on the war exceeded the expectations of even the most ardent proponents of its introduction to USAF service in 1977. The E-3A Sentry aircraft, based on Boeing 707 airframes, were readily distinguished from other 707s by the 30-foot diameter radome enclosing the radar and other antennae by which the aircraft was able to exercise much of the capability which put it so far ahead. An illustration of how it worked is worth giving.
In July 1985 the eighteenth and last of the E-3A Sentries assigned to NATO arrived at the German Air Force base at Geilenkirchen, near the Dutch border, to join the newly-formed European NATO squadron. The last of the thirty-four aircraft retained in the USA had joined 552 Airborne Warning and Control Wing at Tinker Air Force Base near the city of Oklahoma earlier in the year. Crews on this Wing had amassed considerable experience on regular deployments to Keflavik in Iceland, Ramstein in Germany, Cairo West, Dhahran in Saudi Arabia, and in South Korea and Japan. The crews of the NATO squadron, drawn from eleven Allied countries, had not travelled so far afield but had become very familiar with the airspace of central Europe, Norway, Italy and Turkey.
By the beginning of 1985 a regular surveillance pattern had been established in the Central Region of Europe. One Sentry from the NATO squadron was always aloft near Venlo on the German-Dutch border; a second from the USAF flew over Ramstein; and a third, also from the NATO squadron, patrolled to the west of Munich in Bavaria. Stand-by aircraft were held on fifteen minutes’ readiness. Their racetrack patterns were flown at over 25,000 feet. The serviceability of Sentry, based on a well-tried type of aircraft, had always been better than that experienced by new generations of aircraft and by 1985 COMAAFCE could confidently expect a daily 80 per cent serviceability rate from both the USAF and the NATO units. Moreover, with a four-man flight crew, additional to the thirteen men manning the equipment, extensive crew space, in-flight cooking and in-flight refuelling, each Sentry could extend its normal six-hour patrol time by several hours if necessary, which afforded great advantages.
From 1983 onwards, Sentries in both NATO and USAF squadrons had been built with almost identical equipment. The original computer speed had been increased threefold and the storage capacity fivefold. The Sentry computer could now process an incredible 1.25 million operations per second and, if necessary, could communicate with up to 98,000 air and ground users by the joint tactical information distribution system (JTIDS), a digital communications system resistant to ECM. Not surprisingly, in the early years of deployment the technical capacity of the aircraft had tended to outrun the imagination of those responsible for its operation, while there were many who considered its introduction into service premature and its technology potential excessive. In 1981, however, a separate subordinate NATO AWACS Command had been established at Maisieres near Brussels and an Allied staff had worked steadily both to exploit its functions more fully and to integrate Sentry operations with those of the British AEW Nimrod.
