No problem. Searched threads for where to put and since this was more recently used thread on the subject, figure I'd put it here

Grayback's tenth patrol, her most successful in terms of tonnage sunk, was also to be her last. She sailed from Pearl Harbor on 28 January 1944, for the East China Sea. On 24 February Grayback radioed that she had sunk two cargo ships 19 February and had damaged two others (Taikei Maru and Toshin Maru sunk). On 25 February she transmitted her second and final report. That morning she had sunk tanker Nanho Maru and severely damaged Asama Maru. With only two torpedoes remaining, she was ordered home from patrol. Due to reach Midway on 7 March, Grayback did not arrive. On 30 March ComSubPac listed her as missing and presumed lost with all hands.From captured Japanese records the submarine's last few days can be pieced together. Heading home through the East China Sea after attacking convoy Hi-40 on 24 February, Grayback used her last two torpedoes to sink the freighter Ceylon Maru on 27 February. That same day, a Japanese carrier-based plane spotted a submarine on the surface in the East China Sea and attacked. According to Japanese reports the submarine "exploded and sank immediately," but antisubmarine craft were called in to depth-charge the area, clearly marked by a trail of air bubbles, until at last a heavy oil slick swelled to the surface. Grayback had ended her last patrol, one which cost the enemy some 21,594 tons of shipping.Grayback CO, John Anderson Moore was posthumously awarded after this mission his third Navy Cross (see Bureau of Naval Personnel Information Bulletin No. 336 (March 1945))Grayback ranked 20th among all submarines in total tonnage sunk with 63,835 tons and 24th in number of ships sunk with 14. The submarine and crew had received two Navy Unit Commendations for their seventh, eighth, ninth, and tenth war patrols.Grayback received eight battle stars for World War II service.
Eternal Patrol.

There was a second USS Grayback submarine launched in 1958, the first of the Grayback class of attack subs, but later converted to carry nuclear cruise missiles, then converted again to be an amphibious transport submarine. She served until 1984.

The vid notes the deck gun was 117m from the boat. It appears to me the damage from the 500lb bomb that Japanese plane dropped on is right where the deck gun was, just aft of the conning tower.
WASHINGTON, D.C. – A U.S. District Court judge ordered the Navy to start releasing unclassified documents related to the sinking of USS Thresher (SSN-593), 57 years after 129 officers, sailors and shipbuilders died in the nation’s worst nuclear submarine disaster.
Retired Navy Capt. James Bryant, a former Thresher-class submarine commander, sued the Navy in July to force the release of unclassified investigation documents detailing Thresher‘s operation during its final dive. The Navy previously rebuffed Bryant’s request for records under the Freedom of Information Act.
During a Monday court hearing, Judge Trevor McFadden ordered the Navy to start releasing the requested material. Bryant, while pleased with McFadden’s ruling, shelved his excitement until he sees what the Navy starts releasing and whether the documents are heavily redacted.
...
The Thresher disaster spurred the Navy to create its SubSafe program. Bryant, who wrote about Thresher‘s sinking in the July 2018 Proceedings, says there are still competing theories about what caused the disaster.
Sadly it looks to be like it's over for them.
Is this something like "is Tom Clancy's 'Crazy Ivan' maneuver truth or fiction?"Can subs recover from really extreme attitudes like inverted or vertical and is that something practiced? I know it's done with airplanes, sometimes extreme, depending on the skill of the examiner/instructor.
