Yeah, the Churchill always seemed like a real workhorse tank in it's niche. It's true it's not really a very tanky kind of tank, though, it seems like it kind of sat in the role that Germany designed the StuG for.

Also, while it was slow it was kind of infamously good at crossing bad ground and going up steep slopes! :eng101:

This is a good question because in terms of keeping aggro and having enough armour and health to survive doing that it did pretty well :v:

I guess I mean "It was bad at the kind of sweeping armoured maneuvers most other armoured vehicles do", it was a dedicated infantry support vehicle.

As for Churchill, it had the advantage of being roomy enough to allow for lots of different solutions. The first versions had a howitzer in the hull, but this went out of fashion really quick. Unfortunately the Brits couldn't come up with what they wanted from the tank, so they put high velocity 57mm tank killers, medium velocity 75mm multipurpose guns and low velocity 95mm infantry killers on them, probably on random basis, hoping that at least one version would succeed. What a weird design philosophy.

OK, EE, please correct me if I'm wrong on this. The Ferdinand had a loony toons hybrid drive system (gasoline/electric for those that don't know) because Prof. Porsche was obsessed with the idea of very large tanks, and once you get so big you actually have to use the hybrid system? Porsche was right, BTW, the tracked vehicle thing that moves the space shuttle uses engines generating electricity to drive the treads, and those crazy huge coal miner things use the same system (though conveniently they don't need an engine; they just plug themselves in via a gigantic power cable.)

You don't *have* to, but it helps. The advantage of driving your tank with an electric motor is that you can simply adjust the value of a resistor to change how much current goes to the final drive. No clumsy gearboxes or discrete gears, only nice smooth continuous luxury. The downside of this is you have to use two tons of copper per tank, which is all sorts of unacceptable, especially at wartime when you can't even get enough nickel for your armour.

Oh yeah, no argument there. I'm asking was he doing these dumb, impractical things now in the hope of having useful experience when it came time to make the Maus, the Ratte, Ein Terrier (a even more super colossal war machine that I just made up) etc. Or did he do it because he thought the ideal drive train for a tank from a engineering perspective was the hybrid, as you didn't need a mashugana transmission anymore?

Frontline experience. The Ferdinand was expected to be a hell of a lot more common than it ended up being. I don't know when/if the GRU discovered that production was very limited, but the IS-4 was envisioned as an anti-Ferdinand tank.

Can you direct me to sources for this? I would love to read up on what the Soviets were thinking when they saw the Tigers and Ferdinands. Assuming its in English and not Russian of course.

Today I learned that tanks can jump:

wiki posted:

Cromwell was the fastest British tank to serve in the Second World War, with a top speed of 40 mph (64 km/h). This speed was extremely beneficial in both attack and defence, outmanoeuvring opponents. At least one case is known of vehicle commanders using the vehicles fast speed to jump large gaps - In Holland, a troop of three Cromwell's was able to leap a 20 ft wide canal when surprised by enemy forces.

That story is actually amazing. It turns out that the troop commander had ended up in possession of a mild steel training tank that had no armour, and the way they found this out is that they managed to totally clear the canal while the other two tanks in the troop didn't quite and had a moment of cartoon teetering before the tracks bit and pulled them up over the edge.

This was just posted in the Cold War thread:

Captain von Trapp posted:



This is neither air power nor cold war, but when I happened to see it on the Wikipedia main page today I thought the thread would enjoy the history of the Swedish warship Vasa. She was a new kind of flagship, armed to the teeth and decorated decorated to the gills. Her maiden voyage was on 10 August 1628. A little over one kilometer into that voyage, she encountered a breeze, tipped over, and promptly sank. Wikipedia's description of the subsequent inquiry is the fun part:

quote:

The Council sent a letter to the king the day after the loss, telling him of the sinking, but it took over two weeks to reach him in Poland. "Imprudence and negligence" must have been the cause, he wrote angrily in his reply, demanding in no uncertain terms that the guilty parties be punished.[28] Captain Söfring Hansson, who survived the disaster, was immediately taken for questioning. Under initial interrogation, he swore that the guns had been properly secured and that the crew was sober. A full inquest before a tribunal of members of the Privy Council and Admiralty took place at the Royal Palace on 5 September 1628. Each of the surviving officers was questioned as was the supervising shipwright and a number of expert witnesses. Also present at the inquest was the Admiral of the Realm, Carl Carlsson Gyllenhielm. The object of the inquest was as much or more to find a scapegoat as to find out why the ship had sunk. Whoever the committee might find guilty for the fiasco would face a severe penalty.[28]

Surviving crew members were questioned one by one about the handling of the ship at the time of the disaster. Was it rigged properly for the wind? Was the crew sober? Was the ballast properly stowed? Were the guns properly secured? However, no one was prepared to take the blame. Crewmen and contractors formed two camps; each tried to blame the other, and everyone swore he had done his duty without fault and it was during the inquest that the details of the stability demonstration were revealed.[29]

Next, attention was directed to the shipbuilders. "Why did you build the ship so narrow, so badly and without enough bottom that it capsized?" the prosecutor asked the shipwright Jacobsson.[30] Jacobsson stated that he built the ship as directed by Henrik Hybertsson (long since dead and buried), who in turn had followed the specification approved by the king. Jacobsson had in fact widened the ship by 1 foot 5 inches (c. 42 cm) after taking over responsibility for the construction, but construction of the ship was too far advanced to allow further widening.[30]

In the end, no guilty party could be found. The answer Arendt de Groote gave when asked by the court why the ship sank was "Only God knows". Gustavus Adolphus had approved all measurements and armaments, and the ship was built according to the instructions and loaded with the number of guns specified. In the end, no one was punished or found guilty for negligence, and the blame effectively fell on Henrik Hybertsson.[31]

Yeah you're not going to find an English language source for that. There's a good book on the Ferdinand by the publisher arm of Wargaming (the World of Tanks people), but they folded and took all the rumours of an English translation with them.

To a degree, yes. I'm rather fuzzy on all the different flavors of electric motor, but you can adjust the amount of current in the stator windings to control the strength of the magnetic field the rotor current "pushes" against. It's much less than the full rotor current but that adjustment still has to be done via rheostat.

Vaguely related but likely of interest to the thread anyways, have the owners manuals to a WW2-era US fleet submarine. The relevant portion I want to call out is the section on the propulsion control equipment.
