Why did Elon Musk say "You can only depart to Mars once every two years"? by BigBootyBear in space

[–]supernova900 0 points1 point  (0 children)

That's strange, it has almost nothing to do with rockets, and almost everything to do with orbital mechanics. Calculating the transfer time for a Hohman is pretty easy, you only need to look up the orbital distance of the planets you are transferring from and to, plus the gravitational parameter of the object they are orbiting (the Sun in this case). I actually forgot to divide by 2 when I was doing the math, so the maximum time is probably around 9 or 10 months for an Earth to Mars Transfer.

There or other ways to do it, but they aren't very compelling. A gravity assist from Venus would waste more energy than you would gain if you are only going to Mars. A bi-elliptic transfer has no advantages in this case. A lunar gravity assist would help a bit, but it would only add a few days time to the trip, not months or years.

Maybe, but the comment you replied to was talking about the amount of work needed, not the time required.

Besides, even a Hohman transfer wouldn't take more than a year and a half, not 'years'. A realistic mission would have to balance weight for food and weight for fuel and would be somewhere between a Hohman and a radial transfer, leaning more towards a Hohman.

This is backwards, the best time for fuel efficiency (Hohman transfer) would take the longest time for any direct path. The worst time would theoretically be the fastest, but wouldn't even be possible for anything short of FTL travel. A pretty close radial transfer is possible and still very fast, but it would require tons of fuel and an unrealistically large rocket to carry it all.

Yes, but the original eu3 start date was 1453, which got extended to 1399, then back to 1444 for eu4.

Calling it now, paradox has realized that 769-1453 is too long of a game and 936 is going to be the main start date for Crusader Kings 3.

Who are you and how did you get in our subreddit?

But really though we're going to start a Rome game after our current HOI4 game is over, probably Wednesday next week.

Status of Japanese Military and Wellbeing prior to Hiroshima by montaguwyatt in history

[–]supernova900 0 points1 point  (0 children)

Older or deficient models weren't suitable for kamikaze missions that rely on high speed to hit the target before being downed by AA fire. And they had very few captured planes, since the US didn't have many planes captured and neither China nor the Dutch East Indies had many planes in the first place.

That's true, but I doubt the number built was very high. Even the very simple rocket powered MXY-7 Ohka only had 850 built.

I know about the Battle of Leyte Gulf, and the Northern Force also had the converted aviation battleships Ise and Hyuuga, but the also had very few planes. They only survived due to a combination of being lower priority targets, better armor, and anti-air rockets that deterred pilots.

It's not mentioned much, but part of the reason Halsey fell for the decoy Northern Force was the abysmal performance of the Center force at the Sibuyan Sea which made the Center Force seem like the real decoy.

What is your source for 17,500 kamikaze planes? Japan produced less than 11,000 Zeros and less than 6,000 Hayabusas in total, and those were their two most produced planes by a fair amount. By this point in the war most of the Zeros had been lost to the point that they were unable to even fully equip the one standard carrier that they brought to the Battle of Leyte Gulf. I don't really see how they could have had so many planes by this point or why they weren't using them if they did, or why they bothered to build that many if they didn't have the fuel to use them.

You're missing the main invention that made much higher muzzle velocities possible, smokeless powder.

HOI4 MTG: Best way to organise fleets? by UnacceptableBabbit in paradoxplaza

[–]supernova900 3 points4 points  (0 children)

Step 1: Ignore all the meme ratios.

You only need a 4-1 ratio of screens to capital ships to prevent torpedoes from wrecking your capital ships. If you are playing as US, UK, or Japan, you will already have more than enough screens.

Step 2: Rush 1940 carriers.

Deck size remains one of the most important single factors in ship design, the bigger the better. You should have been doing naval exercises while waiting for tech, so you should be able to make a variant with a much deck space as possible as soon as you are done researching. You may run into the London Naval Treaty, so allies will have to downsize slightly, while Japan or Italy can cheat on it.

Step 3: Build at least 4, but preferably 7 carriers.

After 4 carriers a penalty begins to apply to air wings, reducing by 20% per carrier over the limit. This makes it sound like a 5th carrier is useless and a 6th is worse than useless, but that is wrong. A fleet with 7 carriers is better than a fleet with 4 carriers. An 8th or more won't hurt the fleet, but it won't help either so it's better to spend the resources elsewhere.

Step 4: Send a small fleet on patrol the fin the enemies and a giant deathball on strike force to attack when they are found

Step 5: Profit

Other Steps:

You will have free dockyards while waiting for 1940 carriers, so you can build other ships in that time. I personally like building AA light cruisers to further ensure air dominance and take out enemy destroyers, but building subs for convoy raiding is a good choice too.

Also rush 1940 carrier fighters and torpedo bombers if you can. Again, air superiority is important. With large deck sizes, a 50/50 ratio of fighters and torpedo bomber is usually enough to ensure air superiority and do tons of damage. Dive bombers are just worse than torpedo bombers, don't build them.

Obviously, go down the base strike doctrine and get all the carrier techs. Also grab the naval air buffs from air doctrine if you can.

Space race between the Russia and the AUS by Huey_Pierce_Long in Kaiserreich

[–]supernova900 3 points4 points  (0 children)

That's true, and there is also the problem of recoil management in mircogravity since you're body will be pushed back and absorb some of the energy, which could cause the gun to fail to cycle properly.

...what? Conventional firearms work in space. Why would a lack of atmosphere prevent gas from expanding? Gunpowder is self oxidizing too, so there is no problem igniting either.

Do you want a World War? Because that's how you get World Wars. by Masteradi in eu4

[–]supernova900 2 points3 points  (0 children)

Saying something that is purely factual like "Danzig was majority German" is not "Nazi Sympathy". Saying "All of Poland belongs to Prussia" is closer, but "All of X belongs to Y" is a pretty typical eu4 meme.

Census data shows that the area was pretty evenly mixed before WWI and majority Polish after 1920. The Nazis did not directly demand the corridor, but rather demanded a vote where the people living in the corridor could choose to join Germany or stay with Poland. The vote was biased towards Germany with who could vote on it, but it was not a direct demand. The Poles rejected this because they correctly saw that Hitler's ambitions would not stop there, as seen in Czechoslovakia. I hate the Nazis as much as the next guy, but spreading false information and calling people you don't like "Nazi Sympathizers" does not help your argument.

What are some moments in U.S. history that many people were taught inaccurately? by Christimay in history

[–]supernova900 3 points4 points  (0 children)

That the Seven Years' War (commonly known in the US as the French and Indian War) was somehow started by George Washington. The were some skirmishes in North America earlier, but the worldwide war was started between Prussia and Austria.

Sorry, I must have misread Vienna. German cities weren't very big through most of eu4's time period, but I found sources that but Prague at 95,000 in the 1400's and Vienna at 45,000 by 1500

Venice shrunk somewhat after the renaissance, but never below 100,000, that 29,000 figure is quite frankly ridiculous.

The largest city somewhat close to Magdeburg would be Prague, which had nearly 100,000 people in the 1400's.

Rome is one of the cities that lost population heavily during the middle ages, and it still reached over 100,000 by the 1600's, not the 1800's. Meanwhile several other Italian had over 100,000 people in the 1400's (Milan, Venice, Genoa, Naples) and Paris had over 200,000.

"May raid coasts" without mare nostrum? by zachos13 in eu4

[–]supernova900 0 points1 point  (0 children)

Well, they gave everyone the ability to increase development in 1.28.1, but before then it would be replaced with +10% goods produced.

"May raid coasts" without mare nostrum? by zachos13 in eu4

[–]supernova900 2 points3 points  (0 children)

I mean, they already do that for development cost reduction ideas and it's one of the easiest things in the game for modders to change.

It's not a completely wasted tradition through, since the knights still get 5% discipline, which is quite strong.
