Following the Franco-Irish special entente in 1983 the Ministry of Defence in Paris sought Dublin’s agreement to the occasional deployment of one or two maritime patrol aircraft of the Aeronavale (French Naval Air Arm) to Shannon to facilitate their operation in peacetime out in the Atlantic. The twin-engined Atlantique was a very capable and well-tried aircraft and the latest version (Atlantique Nouvelle Generation, or ANG) with which the Flotilles at Lann-Bihouie in Brittany were now equipped was an excellent antisubmarine aircraft which also had a limited anti-ship capability. But compared with its four-engined counterparts (the US Navy’s Orion and the RAF Nimrod) it was just a little short on range and endurance. The lengthening of its sea-legs by working from the west of Ireland would enhance its use in many of its peacetime tasks and, although this was not the basis of the French request, it would be a real ‘force multiplier’ in war.
Irish agreement was gracefully forthcoming provided that advance notice was given (save of course in emergency) and an agreed quota of visits per year was not exceeded. To these stipulations France readily agreed and a system of liaison officers and communications teams was established with Ireland as it had been for several years with the United Kingdom.
The Soviet naval staff were keenly aware of the strategic importance of Eire in any future battle in the Atlantic. Soviet policy was directed urgently to the denial to NATO of the use of air and naval bases there, and of the use of Irish ports and tanker terminals for trans-shipment. It was too much to hope, perhaps, that Irish bases could be made available to Soviet forces, but as a long-term aim it was borne in mind.
It was not the Naval Correspondent of The Times, but merely ‘Our Correspondent in Dublin’, who reported on 12 December 1981 ‘an application from the Russian airline Aeroflot to operate regular passenger services into Shannon… Last year the airport authority built a special fuel depot to enable Russian and other Eastern European airlines to refuel there. Russian tankers deliver the oil directly to Shannon… The inauguration of an Aeroflot service would be welcomed by the IRA which has won consistent moral support from the Russians for their terrorist campaign in Northern Ireland.’ It was therefore with considerable chagrin that the Soviet naval planners learned of the sequence of events by which the Republic of Ireland gradually became committed to a degree of support for the NATO cause. But, as the strength of the Soviet Navy and its Air Force increased, and the prospect of breaking down the Atlantic ‘air bridge’ improved accordingly, the neutralization of Ireland by military means became part of Soviet war plans.
These plans had not, however, fully matured when the Soviet aircraft carrier Kiev, escorted by two Krivak-class frigates, arrived in Cork on 27 July 1985. The group was said to be on a training cruise which would take it to West Africa and Cuba. It had, of course, been tracked by NATO surveillance forces since leaving its home waters in Murmansk and in the normal course of events it would have remained under routine surveillance as it resumed its way south-west on 2 August. For various reasons, however, contact with the Kiev group was lost during the night of 3 August.
Early on 5 August, JACWA received a garbled and delayed report of a very large oil tanker damaged and on fire in Bantry Bay. She had struck a mine. Later that day reports came in of an Irish patrol vessel sunk off Cork, the Fishguard to Rosslare ferry sunk near Wexford, and a Dutch coaster sunk in the approaches to Dublin.
Not until after the war was it learned that while the Soviet aircraft carrier and her escorts had been visiting Cork a comprehensive mine-laying operation was being carried out by six Soviet Foxtrot-class (conventional) submarines. They laid delayed-action mines off Lough Swilly, Bantry Bay, Cork, Wexford, Dublin and Milford Haven, which sank five ships. Only Milford Haven was cleared of mines before a casualty occurred. The shortage of mine counter-measure vessels at JACWA’s disposal resulted in the majority of Britain’s western ports being closed to shipping for several days at a most critical time. Only one of the Soviet Foxtrots was sunk, No. 132, which attempted to withdraw through the North Channel after laying mines off Dublin. Her snort mast was detected by a surveillance radar very recently mounted on the Mull of Kintyre, and Sea King helicopters from Prestwick were actually in sonar contact with the Foxtrot when they received orders, early on 4 August, to commence hostilities against the Soviet Union. It was particularly heartening to the helicopter squadron that the first attack with the new Stingray torpedoes was successful.
Given the excellent liaison already established at Shannon between the French naval airmen and the Irish airport authorities, the arrival there on 4 August, within hours of the outbreak of war in Europe, of four ANG caused little stir. Nor did the landing, shortly afterwards, of a US Navy Orion. This aircraft had been following up a submarine contact some 100 miles south of Cape Farewell, which had been obtained by a Canadian frigate using a towed array passive sonar. Unfortunately the scent had gone cold, and the aircraft was ordered into Shannon, to operate under the Commander, Maritime Air, Eastern Atlantic.
On the morning of 5 August the Orion and two ANG were allotted tasks that took them far out into the Atlantic. Amidst the excitement of that day’s news this did not attract much attention. But what did cause a loud buzz of rumour and speculation in the Shannon communications centre and control tower was when, at 1722 hours, a distinctly French voice came over the loudspeakers monitoring the international distress frequency: ‘MAYDAY MAYDAY MAYDAY’ it called, ‘THIS IS SIERRA QUEBEC BRAVO CHARLIE WE ARE BEING ATTACKED BY FIGHTERS LATITUDE 52.12 NORTH LONGITUDE…’
Here, as in many places all over Europe, the outbreak of war was signified not by any dramatic public announcement like Chamberlain’s address to the British people forty-six years earlier, but by a series of swift and violent encounters.
In this instance, the response was immediate and well orchestrated for the Mayday signal could mean only one thing: a Kiev — class carrier was out to the west and it must be found and sunk before it did any more damage. The two remaining ANG at Shannon and two Nimrods from an RAF base in Cornwall were launched on a search within half an hour. As the ANG climbed out on their search tracks the crews could see smoke rising from the refinery and the main hangars at Shannon and guessed correctly that a salvo of air-launched missiles, probably from a Backfire, had found their mark.
The search area was very large because of the missing and all-important longitude figure, but a fast westbound merchant ship broke wireless silence to report sighting a Forger aircraft on the horizon and this clue shrank the area of probability dramatically. With a new datum to work from, dawn was breaking when a Nimrod picked up the Kiev and its escorts on its radar.
