Russian Submarine Suffers 'Catastrophic' Damage In Ukrainian Missile Strike
https://ca.news.yahoo.com/russian-subma … 41575.html

Russian military sources have tried to downplay the damage caused to the landing ship Minsk and Rostov-na-Donu submarine.
But in their latest intelligence update on the war, the UK’s Ministry of Defence (MoD) said: “Open-source evidence indicates the Minsk has almost certainly been functionally destroyed, while the Rostov has likely suffered catastrophic damage.
“Any effort to return the submarine to service is likely to take many years and cost hundreds of millions of dollars.”
The MoD also said that “there is a realistic possibility” that the dry docks where the two vessels had been situated will be out of action for “many months” while the wreckage is cleared away.

This ariicle is about the recent return of a British nuclear powered submarine, after a six month tour of duty.

The crew appear to have survived, but the author of the article considers the deployment to be "irresponsible". The crew is only 130 people. Compare that to 1060 people for eight months.

In either case it's important to save the equipment and then crew for our space adventures to mars.

Electric Boat in Connecticut built a lot of diesel-electric submarines for the US Navy, from between the world wars until the 1960's, when nuclear pretty much superseded the diesel-electric. I'm not sure about the early designs, but the WW2 fleet subs and their immediate predecessors at the time of the V-boats in the 1930's were all-electric drive, with the diesels running only electric generators to keep the lead-acid batteries charged.
These fleet types were 4-engine boats capable of running up to about 22 knots on the surface, and with 10,000-12,000 nautical mile range if you slowed a bit. The Gato's were test depth rated to 300 feet, while the Balao's and Tench's were rated to a test depth of 400 feet. I've actually been aboard a Balao still on active service with USN as a Guppy-modified boat when I was young. Several of them survived in combat to depths of 600-700 feet.
A lot of the nuclear submarines are direct mechanical drive with steam turbines. Some are electric drive with the steam turbines instead just generating electricity.
Some of the WW1 designs had clutches so the diesels could drive both the generators and the propeller shafts while surfaced. That didn't work out so well as all-electric drive, in terms of reliability. This clutch thing was in the S-class boats from about 1919-to-1925-ish. Some of these served in combat during WW2. They were were 2-engine boats, capable of about 14 knots surfaced, and about 5000 or 6000 nmi range, if memory serves (which it might not at my age). Test depth was 200 feet. One of them survived grounding at 315 feet off China, running from Japanese destroyers in WW2.
The diesel-electric thing done as all-electric drive is a true hybrid propulsion system. In the 1930's it was small enough to fit in a 300-foot-long fleet submarine, and in a railway diesel locomotive. It's small enough now to it in a car. The plug-in hybrids approximate it, but not correctly. You still have a very complicated and expensive transmission accepting shaft power from both an engine and an electric motor, even with the plug-in hybrids.
Hybrid cars really should be done with all-electric drive, and you do not need a complicated transmission. The plug-in hybrids proved that the electric components have to the power and the ruggedness to serve that function. You could put the motor-generator and the fuel tank in a small trailer, that you pull only when you need the range. That trailer could also carry luggage or cargo for you. Again, only when you need it.

USS Columbus receives final funds as it nears overhaul completion

The US Navy’s Los Angeles-class submarine, USS Columbus (SSN 762), approaches the end of its eight-year-long engineered overhaul.
HII Newport News Shipbuilding, a US naval industrial prime and contractor for the submarine’s sustainment since 2015, has received the final funds worth $283.9m. This will see the boat return to active service sometime after December 2025, when the Navy expects the work to be fulfilled.

All I can say is that's too much time to not be available for the Navy to make use of.

Canadian warship sharing an anchorage with Russian vessels in Cuba
https://uk.news.yahoo.com/canadian-wars … 00110.html

The Royal Canadian Navy now finds itself in the unusual position of both shadowing Russian warships as a threat in the Caribbean and sharing an anchorage with them as a guest in the port of Havana — because Canada accepted an invitation to send a patrol ship to Cuba while the Russian navy is in town.

The Russian ships are expected to leave Cuba and head for Venezuela, where the Nicolas Maduro government is another major backer of Putin and the war in Ukraine.
"The Canadian Armed Forces will continue to track the movements and activities of the Russian naval flotilla" after it departs Havana, Kened Sadiku of DND told CBC News.
