By the start of the war some of the US AF’s A-10 Thunderbolts had been given a bad-weather and night capability, but so had the Soviet SAM, so that any advantage to the A-10s was to some extent offset. When surprise was achieved, or the enemy defences were degraded, the Thunderbolts with their massive firepower could wreak havoc on the enemy’s armour, but in less favourable circumstances their losses would be almost too heavy to sustain. It was with some misgivings about the likely loss rate that the staffs of 4 Allied Tactical Air Force (ATAF) and CENTAG had approved, a year or so before the war, a programme of tactical trials to modify their existing co-ordination between the US Army anti-tank helicopters and the USAF Thunderbolts. The approved doctrine hitherto was for the helicopters, hovering in ambush, to open fire on the armour with their guided weapons for thirty seconds before the Thunderbolts came in, and then to pop up again to give the surviving tanks another thirty seconds’ worth when the Thunderbolts had finished. The idea came from the US Army Cobra helicopter pilots that their own effort might be better directed at the easily recognizable Soviet ZSU radar-controlled anti-aircraft guns and SAM vehicles which would be providing the tanks with anti-air protection. If they did that, it was argued, the Thunderbolts would have, if not an unrestricted, at least a much less fiercely opposed run at their targets. Ground force commanders were sceptical. The threat was from the tanks and there would never be enough anti-tank weapons in the right place at the right time. What there was should be directed at the main threat. The Thunderbolts might not arrive anyway.
The trials were promising, but without real action no one could be sure what would be best. In the event, adoption of the new tactics was at first cautiously limited to the new Hughes AAH-64 helicopters of 8 Aviation Combat Division of the US Army Air Corps at Finthen, Germany, working with USAF Thunderbolts deployed forward to Germany from their English base in East Anglia. The wooded knolls around Fulda, for example, were to give excellent cover to the ambushing helicopters with their Hellfire missiles, and the enemy’s defence vehicles were, as predicted, clearly visible against the squat Soviet T-72 tanks and BMP around them. With the ground defences at least temporarily stunned and degraded, the Thunderbolts, in relatively slow runs, could concentrate their fire with deadly effect against the tanks. Happily it had just been possible in the two years before the war to extend these tactics widely. Helicopter attack on tanks, sometimes in conjunction with A-10 Thunderbolts, on the lines worked out between the US Army Air Corps and the USAF were to be a frequent and powerful element everywhere along the Central Front.
The five-year projection in FY 1983 also provided for substantial increases in USAF flying hours, which had been cut back, just as they had been in European airforces, to dangerously low levels under budgetary pressures in the late 1970s. While this USAF programme was one to excite the envy of airmen across the Atlantic, much of its emphasis was nevertheless consistent with what Europe was having to do — namely, enhance and develop what already existed rather than insist in vain on new types.
The RAF was the only air force in the alliance to operate all the roles of air power (in the USA the maritime role was discharged by the US Navy Air Force). It is therefore instructive to look back at some of its problems in the five years before the war.
Although the British Government endorsed and generally adhered to the 3 per cent annual growth of defence spending in real terms agreed by the NATO Council in 1977, each year saw greater difficulty in containing the programme costs within the increased defence budget. Something always had to be dropped or deferred. A formidable ‘bow wave’ of unfulfilled operational requirements was being pushed ahead of the defence programme. As economic pressures increased, existing capabilities had then to be trimmed back because of rising running costs — a process that came to be termed rather bitterly in British defence circles ‘salami-slicing’. As matters got worse in the years of economic recession, flying hours and ground transport fuel were cut and (almost incredibly) officers and men were sent on leave to save money. The shoe, and more especially the flying boot, was pinching hard.
