On 20 March 1994, a British Army Lynx helicopter was shot down by the Provisional Irish Republican Army (IRA) in Northern Ireland. A unit of the IRA's South Armagh Brigade fired an improvised mortar at the British Army base in Crossmaglen, County Armagh. The mortar round hit and shot down the helicopter, serial number ZD275, while it was hovering over the helipad. Three British soldiers and a Royal Ulster Constabulary (RUC) member were wounded.


Since the 1970s, the IRA developed a series of home-made mortars. The goal was to produce devices to be use as "stand-off" weapons, capable of being launched from safe ranges upon police or military outposts, and easy to conceal on dead-ground.[1] The different designs evolved in 1992 into the Mark 15 mortar, widely known as "Barrack buster". The mortar shell consisted of a one metre long metal propane cylinder with a diameter of 36 cm that contained around 70 kg of home-made explosives and with a range between 75 and 275 m. The cylinder was an adaptation of a commercial 'Kosangas' gas cylinder for heating and cooking gas used in rural areas in Ireland.[2] The first use of the "Barrack Buster" took place on 7 December 1992 against a security base in $3, County Tyrone.[3]

The attack

IRA's Barrack Buster mortar

On the evening of 20 March 1994 a Lynx helicopter, serial number ZD275, was in the process of landing at the large British army base at Crossmaglen. Meanwhile, an IRA unit had mounted a Mark 15 mortar on a tractor, concealed behind bales of hay. The tractor was parked 150 yards from the intended target, on waste ground. At 20:27, there was a sudden blackout across Crossmaglen's square and at the same time, a single mortar shell was lobbed into the barracks. The IRA had used the mains for the collapsing circuit of the firing pack, turning off the street's power supply and allowing the mortar's own battery to trigger the launcher. When the Lynx was hovering 100 feet over the helipad, the mortar round hit the aircraft on the tail's boom, which was severed from the fuselage. The machine span out of control, but the pilot was able to crash-land the Lynx inside the base. A Grenadier Guards' patrol spotted a huge orange ball from a mile away. Three members of the crew managed to get out with minor injuries, but a member of the RUC was trapped inside the blazing wreckage. The constable was rescued just before the fuel tanks and the ammunition started to explode. Author Toby Harnden described the incident as the most successful IRA operation against a helicopter in the course of the Troubles.[4][5][6][7]


After the incident, the IRA and Sinn Féin bore criticism from the SDLP Member of the Parliament for the area Seamus Mallon, who said:

God knows how many people could have been killed. When you realise this mortar was lobbed over a number of houses it brings home the enormity of the danger so many people faced. Yet again you have Sinn Féin talking peace in the morning and carrying out these murderous attacks through the IRA in the evening.

John Fee, a local SDLP councillor which dubbed the attack as "an act of lunacy" was later beaten by two men outside his home. The IRA denied responsibility.[8]

Corporal Wayne Cuckson of the Royal Logistic Corps was awarded the Queen's Gallantry Medal for dragging the wounded constable out of the crashed aircraft.[4] Corporal Robert Tomlinson of the Royal Military Police was also awarded the Queen's Commendation for Valuable Service for his part in coming to the aid of the wounded RUC Constable and Soldiers.

There was a second mortar attack on a British military helicopter on 12 July 1994 at Newtownhamilton, when a RAF Puma, serial number XW225 and carrying 12 soldiers crash-landed on a soccer pitch after being hit on its tail by another Mark 15 mortar launched from a tractor. No serious injures were reported.[4][9] The Puma sustained Category 3 or Category 4 damage on the RAF scale. Back to service, the machine was definitively written off and scrapped after suffering another crash-landing in Germany on 15 February 1997.[10]

The downing of two helicopters by mortar fire, along with the increasing sniper activity of the IRA, was both a morale and military blow to the British forces in south County Armagh.[11]
