| Built By: | Pembroke Dockyard |
| Build Group: | H21 |
| Fate: | Sold to the Breakers November 1927 and then sold on to a film company. Disguised as a U-Boat for the movie 'The Q-Ships' and sunk of Eddystone Lighthouse by gunfire in January 1928 |

During an exercise, H52 had a lucky escape after being hit by a surface ship while running submerged. Extensive damage was done to her bridge and conning tower and her main periscope was bent.
Possibly as a result of this damage, she was sold to a film company and disguised a a U-Boat for the movie 'The Q-Ships' and sunk of Eddystone Lighthouse by gunfire.

The Adriatic, radiant in summer, with its many islands strung like jewels along the Dalmatian coast, is a pleasant sea in time of peace. With the Axis occupation of Yugoslavia and Greece, it became yet another area of perilous opportunity for the Submarines of the Royal Navy. Among the shoals off Italy's eastern seaboard and the innumerable islands of the Yugoslavian coast, where the enemy played a desperate game of hide and seek with his ore ships bound for Fiume, the Submarines carried out many adventurous patrols.
It was obvious that whatever had caused Affray to sink, and had ended the lives of all those on board, had occurred quickly.
Sixty years later, in this compelling maritime investigation, Alan Gallop uses previously top secret documents, interviews with experts and contemporary news sources to explore how and why Affray became the last British submarine lost at sea, and possibly the greatest maritime mystery since the Marie Celeste.
