The Besson MB.35 "Passe-Partout" and its derivatives MB.41 and MB.411 are French observation seaplanes designed to operate from the submarine cruiser Surcouf. Two MB.35 prototypes were produced, one of which was lost by accident, and the second was converted into the MB.410 prototype was...

I found short article in MILTECH on the AMPS, a Canadian project for a small scale nuclear reactor for use as air-independent-propulsion in submarines. Further research turned up a couple of interesting studies, which i attached to this post. THE AMPS 1000: AN ADVANCED REACTOR DESIGN FOR MARINE...

NAVAL FORCES 1985 had a special supplement about Thyssen Nordseewerke including this depiction of the 'Thyssen Submarine Family' (image source) Of the submarines shown, only MSV 130 and TR 1000 are unbuilt projects. The supplement has articles on both of these, but i can only find it for sale in...

Since the only Canadian submarine related thread is in the alternative history section (https://www.secretprojects.co.uk/threads/canadas-next-submarine.41251/#post-590211), I've decided to make a new dedicated thread for the actual, very real program.

I would like to make a comparison of these two submarines. I mean sonar system, acoustic technology , speed and overall technology comparison. I would also like to know what is amazing about ssn 790 south dakota that everyone writes about some acoustic advantage over other subs.

A friend of mine has asked me to check out a rumour that HMS Cockade sank a suspected Soviet sub while serving with a US force in the Korean War. He thinks the papers are embargoed until at least 2050.

Usual caveats apply, full size cutaway at http://www.hisutton.com/Type-XXI-U-Boat-of-World-War-Two.html The Type-XXI was important in a lot of ways, but had the Ursel rockets made it into service I think it could have further reshaped Cold War submarine equipment, at least in the immediate...

H/t moin1900:

I am reasonably familiar with axis submarine projects, built and unbuilt, c1945. We're there any interesting British or American projects at this time beyond the typical A-Class and Fleet Boats? From what I've read it seems that the allies were content to build large numbers of relatively...

I'm just wondering, have any drawings or artist impressions of the original Project 705 design, before they changed over to the design that would lead to the Alfa class, surfaced (no pun intended!) in recent times?

I thought it might be time for a dedicated thread on the Upholder class subs in Canadian service. I'll start it off with this; Via HP&CA: Victoria submarine torpedo test fire marks milestone (The Vancouver Sun) The fire damaged HMCS Chicoutimi, one of the Canadian military's four submarines...

I have been looking at the RN T class submarines and their post war service, in particular there reconstructions. A large number of the boats seem to have survived into the 60s but I have only been able to identify 8 welded boats and 5 riveted as having undergone reconstructions. My question is...

In 1949 a preliminary draft for a missile submarine designated Project P-2--to strike enemy land targets--was drawn up at TsKB-18 (later Rubin) under chief designer FA Kaverin. The submarine was to have a surface displacement of almost 5,400 tons and carry 12 R-1 ballastic missiles, a Soviet...

In the mid 1980s, the Soviet Navy determined that a new weapon system was needed to deal with the ever-increasing power of US Navy carrier battle groups. At the time, the Project 949 (Granit) and Project 949A (Antey), NATO reporting names Oscar I and Oscar II, nuclear-powered guided missile...
