nuclear powered vessels

The US Navy in the 1980s deployed an impressive range of non-AEGIS cruisers. Long Beach was the largest and oldest of the nuclear ships and the only one to start life as a cruiser. The remainder started as frigates then became DLGNs. Bainbridge and Truxtun were one-offs followed in the 70s by 2...

The first study: Saipan class light carrier. Length: 690.69 feet. Beam: ~180 feet max. 80 bow. Waterline bean: ~90 feet 35,000+ tons for bottom configuration 25+ knots. Aircraft complement: 16 F-35C 2 EWAR drones 4 ASW drones 4 AEW drones 2 helicopters I independently arrived to a...

I have a question although not dealing with warships. End 1950s-1960s the Warnow Werft, Rostock, East Germany intended to built a nucelar-propelled cargoship/freighter to be completed by 1965; the decision for the project dat from 19 November 1957. In 2023 professor-ing. Franz Spychala held in...

Single steam loop? Go F yourself, Mister DeGaulle! There's a reason everyone else keeps the primary loop inside the reactor compartment and lets it boil water in the secondary loop to spin the turbines.

Hi! ALL HANDS MAGAZINE SEPTEMBER 1961 PAGE: 39 "OPERATION CRYSTAL BALL" In 1961 RADM Roy S. Benson asked everyone in the sub force to submit ideas for "future" submarine weapons etc. Some ideas - "depth charging" surface craft - underwater submarine tender - sailless submarines - addition of...

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...

I was curious to see if there had been any drawings of this paper ship plan. Basically a anti sub/ trade lane protector ship for th usn, 20 s-3 in 2 squadrons plus 4-8 small anti snuper aircraft (presumably a-4 but no design specified) and 16 sea kings, to be biult in the 70's to replace the...

Folks, Everyone knows Canada is in the early stages of replacing its surface fleet with a Type-26 derivative to be equipped with TLAM. It's purchasing 88 F-35s. Lot's of politics in their current defense procurement plans. How should it refresh its submarine force? Canada briefly flirted with...

The Royal Navy began the 1960s with two excellent classes of destroyer (County DLG).and frigate (Type 12 Leander) on order. In 1966 the replacement of these ships with the T42 and T22 was set in hand.. In addition the T21 gp frigate was ordered to replace other frigate classes. So not a lot of...

I came across this project in a 1968 United States Atomic Energy Commission booklet, The ATOM and the OCEAN, by E. W. Seabrook Hull (can be found on Project Gutenberg here). The National Science Foundation had proposed an Arctic Drift Barge for Arctic research, which would have a nuclear plant...

Ok, this is a scenario I've been working on for a while now, so I'd like to hear other peoples' thoughts on it. It has some plot devices though (the Soviet Union not completely falling apart, Bush restarting the Cold War, etc), but I think it's realistic enough to seem sane from a glance. In...

The Royal Navy in the 1960s has been the place for many alternative history threads helped by the excellent books on the subject and the enthusiasm of Brits like me for CVA01 and co. The US Navy offers even more scope for programmes that could have been. Some thoughts to kick things off...

Does anyone have any information on the French design at least? The program was a precursor to the equally ill-fated (non-nuclear) Polar 8 icebreaker program of the 1980s. The only hard info I have on the French proposal at the moment is that the reactor was a CAS (Advanced Series Boiler)...

Navy's Next Attack Submarine Will Be Wider And Based On The New Columbia Class Missile Boats The SSN(X) design will be wider than the present Virginia class, offering improved capabilities and increased stealthiness underwater. Does anyone have any thoughts on displacement, size and weapon...

Surprised that this wasn't being discussed or have its own thread but it regards militarization, icebreaker projects, living in cold conditions, transporting fuel, possibly another area of conflict later. Examples of starting off thread to get the general idea...

Also somewhat confusingly referred to as the Leader-class, not to be confused with what is now the Project 23560E Shkval-class light cruiser. https://www.navalnews.com/naval-news/2020/07/russian-shipyard-begins-construction-of-leader-nuclear-powered-icebreaker/ ORIGINAL CAPTION: The Leader...

Amongst my favourite warships were the dramatic US Navy Albany class double ended missile ships. According to the Friedman US Navy cruisers and battleship books more conversions like this were planned. My favourite Mack conversion would have been the unfinished battleship Kentucky...

As I hate cluttering up the NIGS thread with speculative what-ifs I have finished my tinkering with Hampshire rebuilt with the NIGS as depicted by portions of the NIGS plans. The only non-NIGS radars are for 978 for surface-search and a Mk 10 IFF antenna and the ESM systems. I kept both 'Cooky'...

This was a project intended to provide three (correction, four) atomic powered high speed container ships for use on Essential Foreign Trade Route No. 12, between the U.S. Atlantic Coast and the Far East. The ships would have used the AEC Maritime Reactor, a clean sheet gas-cooled reactor design...
