Obtaining the plutonium from the seabed would be a major project for any human group, because you'd have to hover around the areas where the carriers were sunk, and search the ocean floor laboriously to find the wreckage and extract what you were looking for. For Abyssals, it's not clear whether they even CAN use Earthly weapons; they seem to have some kind of logistics but it may have more to do with metaphysics than with physical goods.
To give an idea of just HOW major a project it would be, consider that
Project AZORIAN was a CIA operation in the mid-70s to recover, primarily, the nuclear weapons aboard the sunken Soviet missile submarine K-129. It cost billions of dollars, required a year of searching with a special-missions submarine modified specifically for seabed search, construction of two special ships and a specialized piece of recovery equipment under the cover story of being a Howard Hughes project to mine manganese nodules from the ocean floor, and took two or three years to complete... and, at least according to the official story, it was largely a
failure when the recovery claw broke and most of the submarine, including the missile compartment, fell back to the bottom. (The veracity of that part of the story is questionable, but irrelevant to what a massive project it was.) Any project to recover nuclear weapons from other sunken sites would be similarly difficult; as proven in
the 1966 crash of a nuclear-armed B-52G off Palomares, Spain, nuclear-armed nations would go to great lengths to recover any lost nuclear weapon that seemed to have even a slight chance of being feasible to recover, so the "easy" ones have already been recovered. The remaining ones are all either
under at least 9800 feet of water or
even deeper than that;
buried so deep in mud that we haven't been able to precisely locate them, much less recover them; or
completely bloody missing to the point where
nobody knows where they went. (There have been some
other such incidents that I didn't link, but again, if the weapons were at all retrievable, they were retrieved by one side or another.)
Plus, they're fighting according to World War Two rules, which lends itself admirably to their gun armament. Do their Harpoons perform according to spec, or do they experience the same level of epic fail everyone else's missiles do?
I would expect they would have similar performance to the
ASM-N-2 Bat or
LBD Gargoyle anti-ship missiles; both are rough equivalents (albeit air-launched) that were in service or live-fire testing by the end of WW2.
The Iowas get to cheat, by virtue of being the sole surviving real battleships.
Well, not the SOLE remaining ones. If the industrial effort to reactivate Showboat, Mamie, and Bama ever bears fruit, they'd also get to cheat;
Salem,
Little Rock, and all the surviving Fletchers would presumably also get to cheat if reactivated. (Yes, the Des Moines class didn't enter service until after the war, but they
would have been in service in time for the Invasion of Japan, had the war not ended when it did, so I figure that they get to count as "1945" ships.) Also,
Mikasa and Texas would like to have a word with you... :lol
By launching a glide-bombing, low-altitude attack, the B-1s may have accidentally (or not so accidentally) made themselves more effective. That's an attack profile that works under World War Two rules, whereas level bombing from thirty thousand feet generally doesn't. This enabled the B-1s to score at least some hits with their bombs. The same carpet-bombing attack, dropped from a higher altitude, might well have failed or been less effective.
Not so accidentally--JMPer said that part of the reason Bones were used for the attack on Atomic Princess was that their crews were about the only four-engined bomber crews crazy enough to try supersonic dive bombing in such a big bird.
Incidentally, this is why fears about nuclear reactors becoming nuclear bombs are utterly baseless. Reactor-grade uranium doesn't have enough U235 to go kaboom.
When Chernobyl's Reactor #4 suffered
its catastrophic accident in 1986, it's now known that there was a prompt criticality runaway reaction in part of the core, similar to a
fizzled nuclear weapon, with an explosive yield of about ten tons (no, not kilotons); given the design of the RBMK reactor in the accident (as compared to other nuclear reactors), this is a close upper bound on the maximum nuclear yield possible from a worst-case scenario with a nuclear reactor.
Photos of Yamato's magazine cooking off are DISTRESSINGLY mushroom shaped in that way only truly awful explosions can be.
Mushroom clouds are not limited to large explosions. Any explosion that results in a bubble of hot gas rising and cooling will form a fine mushroom cloud. I've seen a fire department demonstration of extinguishing a diesel fuel fire where the ignition of about a gallon of diesel generated a mushroom cloud about fifty feet high. I've also accidentally caused a quite lovely three-foot-high mushroom cloud when I spilled some alcohol into a bunsen burner in a chemistry lab.
Why everyone insist on calling Project 1144 Orlan Heavy Cruiser, a battlecruiser with NATO classification -_- ?
Because 24,000 tons displacement and 2x the armaments of the three next largest surface combatants.
As for the NATO classification, not only is "Kirov" the familiar name for the class in Western circles, wasn't it also the original name of the first ship of the class? By US Navy standards, that would mean that the class would be referred to as the "Kirov class," even if the ship was renamed later.
