Affray - Subsmash CommentaryRead
The relatives and the author are not the only ones who would like this mystery solved and I am sure so would the many who served at the time or later, on the sister ships of the Affray, but I don't want to know at the cost of bringing indignity to the remains of these men have no doubt that others with better technical qualifications and easy access to the archives would be able to more comprehensively review the loss of the Affray , but this is simply a commentary by a former submariner of the time on a recently published book about the loss

Sports divers using new deep water techniques have reached the wreck of the Affray, the Royal Navy submarine in which 75 sailors lost their lives almost 50 years ago in a disaster that remains shrouded in mystery.
 
Disaster Beneath the WavesRead
HMS Affray was the last RN submarine to be lost at sea. At the time of her sinking, rumours about the cause of her loss circulated widely. Many were discounted once her final resting place had been found and the Official Inquiry's report had been published. However, speculation persists to this day as to the reasons why she sank.

Events

16-01-1944 : Laid Down
12-04-1945 : Launched
02-05-1946 : Completed
16-04-1951 : HMS Affray left Portsmouth to take part in Exercise Training Spring with a training class of young officers aboard, her orders being to make a daily report between 9am and 10am each morning and to land a party of Royal Marines on any suitable beach in the patrol area during the night.

On the morning of the 17th Affray failed to report her position as required and rescue vessels were immediately put on alert as repeated attempts to call up the submarine failed. It was known that she had intended to dive 30 miles south of the Isle of Wight, so the search was concentrated off the island but the exact position of Affray was unknown. A number of vessels involved in the search reported faint Asdic signals and the submarine Ambush decoded a message stating, WE ARE TRAPPED ON THE BOTTOM but the Affray still could not be found.

On the evening of the 19th the Admiralty regretfully called off the search. While the search for survivors was now fruitless the search for the Affray was to continue.

In the middle of June, after nine weeks of searching, an underwater camera focused on the submarine's nameplate. Her final position proved to be 37 miles from her known diving position. She was lying on an even keel on the edge of a series of underwater chasms known as Hurdís Deep in the English Channel. Divers could find no evidence of collision damage but noted that her radar aerial and periscope were raised, indicating that she must have been submerged when she foundered. Both hydroplanes were in the rise position indicating that attempts to raise the submarine must have been in operation before being finally defeated by the incoming water.

A reason for the disaster was however soon found when the snort mast was examined. A clean break was discovered 3 feet above the deck leading to the conclusion that metal fatigue had caused the loss, allowing water into the boat through a 10-inch hole. This was confirmed by tests carried out on the recovered mast at Portsmouth, all assertions as to a collision being quashed. Exactly what caused the snorkel to shear at the time it did will in all likelihood never be known.
