How the Falklands War (Thanks to a Stealthy Submarine) Could Have Gone Very Differently

National Interest – The brief but bloody naval war that occurred in 1982 over the Falkland Islands, known as the Malvinas in Argentina, is typically viewed as a triumph of British naval power. A Royal Navy task force managed to beat off heavy air attacks to take back the South Atlantic archipelago from Argentine troops. For most of the war, a lone Argentine diesel submarine, the San Luis, opposed the Royal Navy at sea. Not only did the San Luis return home unscratched by the more than two hundred antisubmarine munitions fired by British warships and helicopter, but it twice ambushed antisubmarine frigates. Had the weapons functioned as intended, the British victory might have been bought at a much higher cost.
