1982: A Royal Air Force Avro Vulcan bomber based on Ascension Island attacks the airfield at Port Stanley on East Falkland Island. It is the first strike of Operation Black Buck, a series of five very-long-range missions to strike Argentinian positions in the Falkland (Malvinas) Islands. Each mission requires a 16-hour round trip of almost 8,000 nautical miles (9,200 statute miles; 15,000 km); they are the longest bombing missions in world history up to that time, and are not exceeded in distance and duration until the 1991 Gulf War.
