It's really too bad the US doesn't have a hot tub/sauna culture...
Anecdotally, in the Finnish navy, every single ship has a sauna despite all of them being rather small (the upcoming four corvettes / frigates will also have saunas). Finnish and Estonian peacekeepers deployed to different parts of the world also always immediately build a sauna in their base no matter how hot or cold the climate. Interestingly, the world's largest wood-heated sauna, which is capable of simultaneously serving 200 bathers or roughly a full company, is located in the premises of the Finnish Naval Academy (Merisotakoulu / Sjökrigsskolan) on the island of Pikku Mustasaari / Lilla Östersvartön which is a part of the fortified islands and UNESCO world heritage site of Suomenlinna / Sveaborg just south of the city centre of Helsinki / Helsingfors. End of off-topic.It's really too bad the US doesn't have a hot tub/sauna culture...
Due to lack of sauna/shared hot tub culture, nobody in the US cleans themselves adequately so US hot tubs are fucking disgusting.The thought of a bunch of US sailors in a shared hot tub gives me hives.
Why is the crew larger for turbo-electric? More systems to maintain?The electric drive is the single largest contributor to the extra size, but there are lots of things contributing to it. For example ORP will have a big upgrade in living conditions, with particular attention to accommodating mixed-gender crews, and that requires space.
826 crew size is the same as the 726s, that's essentially just the size that USN wants for an SSBN.
The British came up with 9 units as the minimum for maintaining a Polaris deterrent in the Indian Ocean as well as the Atlantic. As I recollect, when the UK looked at the possibility of 4 Trident missile tube SSN/SSBN hybrids to replace the Vanguard class, they came up with 9 units again, albeit in the context of single ocean deterrence.Just because there was no mechanism in New START for automatic extensions doesn't mean it could not be extended or replaced by a follow-on treaty (Newer START). The Russians wanted that until at least 2020, if not 2021.
The Navy studies that led to Columbia looked at force numbers as well as missiles. Cutting the fleet below 12 boats doesn't leave enough subs at sea when you account for overhauls, crew turnovers, etc. so you can't get away with fewer than 12 subs, even if you add missiles to keep the total number of launchers constant.
It's not larger, but it's not really any smaller, either. You still need the M division guys who own the turbines, you still need E division to operate the electrical generation side of things, you still need Reactor Controls to keep the reactor working, and you still need those skirts in Reactor Labs to tell you how much radiation you didn't get.
Nope, the Ohios were refitted with a separate head for the women. It replaced the Crew's Study in Missile Compartment 3rd level starboard side (and I believe relocated the COB's office). Ohios already had a bunch of 9-man bunkrooms outboard of the missile tubes on MC3L from the get-go, so assigning 1-2 to the females was no big deal. But there was no way to have them take over one head, there's only 4 showers for the junior enlisted and 6-8 toilets between the two heads on MC3L.The Columbia's are supposed to have fully separate Male and Female crew berth areas, SSN-796 expected to be commissioned at the end of the year is the first Virginia class that will have separate berths and heads by gender along with ladders for bunk beds, signage mounted lower and extra showers. Ohios have been refitted with separate sleeping area but share the same showers and toilets while until New Jersey only female officers have been allowed on US SSN's not enlisted.

I'd really love to see what they laid out for crew habitability space. With 8x fewer tubes (edit: and the same overall length), that opens up a good bit of space for things like exercise gear.
An Ohio has about 65,000shp and 2x ~10Megawatt generators. 65khp is somewhere around 50 megawatts electrical (depends on drivetrain efficiency). So you need much bigger turbogenerators, and then a very big electric motor to drive the shaft. This electric motor is longer than the reduction gearbox.Why does turbo electric machinery take up so much volume? I would think you just increase the number of turbines for power generation (maybe 4 ish) and then have an electric motor instead of all the reduction gears. I do not see why more length is needed to accommodate it.
So somewhat like Ohio SSGN variant, can't some or all of the Columbia's be considered "Hybrid SSBN/SSGN"? Having ~%25 of tubes with VPM's installed allowing for(I think) ~4 x Tomahawk/UUV/etc and/or 3 x Hypersonic missiles and do so randomly so as to maintain aspect of "stealth/secrecy" leaving enemy questioning where "conventionally" armed boats are etc.
I'm just trying to address the concern that we lack enough "Strike-length" VLS tubes once Tico's and Ohio's are both gone, and no "Arsenal-USV's" or DDG(X) have arrived yet...
So, this is likely well known and understood already but the Columbia's missile tubes are the same as the Ohio's 87 inch...

It probably could be done, yes.So, this is likely well known and understood already but the Columbia's missile tubes are the same as the Ohio's 87 inch...

Well there's a good indication why the Navy's pushing SSNX back another 5 years I guess.Online discussion from the Peter Huessy series sponsored by the National Institute of Deterrence Studies.
Early congressional discussions to ask the Navy what it would take to add two quad packs - missiles 17-24 - to Columbia number 8-12.
Short answer: quite a bit, you'd need to seriously mess with the ballast tank sizes!Online discussion from the Peter Huessy series sponsored by the National Institute of Deterrence Studies.
