The very famous video is of USS Pickerel (SS-524), a GUPPY II boat, during a test of emergency surfacing capability off Hawaii on March 1, 1952, under the command of Cdr. Paul Schratz. The official Navy version is that the Pickerel accelerated to full speed at 150 feet, then emergency surfaced, achieving a maximum deck angle of 48 degrees. Crew scuttlebut says that Cdr. Schratz rang up flank speed at 250, blew all, and ordered 60 degrees up-bubble. The planesmen overshot and lost the bubble at 65 degrees. Based on the high-water mark in the pump room bilge, maximum up-angle was claimed to be 72 degrees! The whole thing was captured on film by USS Queenfish, the test observer boat.

An interesting aside that I found online is that, at the time the famous still was made, Pickerel's screws were still about 200 feet deep!

BTW, SS-542 was not a WW2 boat. Although she was launched in 1944, SS-524 was not commissioned until 1949. The WW2 Pickerel, SS-177, was lost with all hands on her seventh war patrol in mid-1943.

Well, if you are going to mess up, I guess it's better to "go big" before you go home!

Thanks for info...
