When it comes to military history, the Guinness Book of World Records – like the rest of the public – only knows what it's allowed to know. For the longest time the Guinness Book gave the award for the longest continuously submerged patrol to the HMS Warspite – one of the Royal Navy's storied names.
While there have been longer patrols the mission of the Warspite happened at the height of the Cold War, prowling the waters around the Falkland Islands after the end of the UK's war with Argentina.
This Warspite was the eighth vessel to carry the name.
The Warspite had a number of innovations that made it perfect for its 1983 submerged mission. It was the first Royal Navy vessel navigated entirely by gyroscope. Its nuclear-powered engines, along with air conditioning, purification systems and electrolytic gills allowed it to be submerged for weeks at a time. The longest time below the waves wasn't even its first record. During a 6,000-mile journey in the far east, the submarine did the entire run submerged, earning the then-record for longest distance submerged. But breaking records wasn't the Royal Navy's mission, it was countering the Soviet Union.
No naval force on Earth was better at penetrating the USSR's maritime boundaries than the Royal Navy. Warspite was specially suited for spy missions in the cold waters of the Arctic. Its ability to sneak into the areas undetected allowed them to watch the Soviet Navy at work and listen to their uncoded communications. But its record-breaking underwater patrol didn't come against the USSR, it came while watching Argentina.
The now-decommissioned HMS Warspite.
The ship had just completed a complete, three-year refit after a massive fire nearly caused the captain to scuttle the ship. It was finished just in time for the United Kingdom to go to war with Argentina over the latter country's invasion of the Falkland Islands. In a rush to get into the action, the crew of the Warspite shrugged off the six-month trial period and dashed for the war.
She didn't see much action in the war, but its patrol afterward was the stuff of legend at the time. The ship and its crew spent more than 112 days aboard ship and underwater, keeping the Argentine Navy at bay.
