On 25 May 1982 in the Falklands War, he sank the transport ship Atlantic Conveyor with an Exocet AM.39 anti-ship missile.

They were sent to the air naval base at Landivisiau in Finistère, north-west France where they then learnt how to fly the AMD-BA Super Étendard, being given up to 50 hours of flight training each.

The Argentines had problems with spare parts for their airborne radar aircraft, which were effectively grounded on 15 May 1982.

At 7:30 am, this information was passed to the naval air base at Rio Grande (now Hermes Quijada International Airport) on the Tierra del Fuego.

Along with Super Étendard 0754/3-A-204, he took off (using a call sign "Tito") at 14:28 and rendezvoused with a KC-130H 160 miles (260 km) east of Puerto Deseado.

Without refuelling, the aircraft had a range of 380 miles (610 km), and at low level used 70 litres of fuel per minute.

On 16 August 2011, he gave a talk at the Centro de Graduados del Liceo Naval Militar (Naval Military Lyceum Graduate Centre) entitled SuperEtendard Squadron, a nightmare for the British fleet (Spanish: Escuadrilla de SuperEtendard, una pesadilla para la flota británica).

His father, Roko Ćurilović, (he later changed his name to Roque Curilovic) emigrated to Argentina in 1926 and married to Isis Taricano (whose mother is a Croat from Split).

Today he works as an expert consultant for a number of defense companies that operate in Argentina and around the world.
