    Post cool pictures (including art) of aerospace object here.
  2. General Naval Warfare News/Technology thread.

    oh my god us navy get your shit together http://time.com/5030829/uss-benfold-tug-boat-collision/
  3. Random Space Exploration Dump Thread

    In successful launch vehicle news, one of the final Delta II launches happened early this morning; http://www.spaceflightinsider.com/space-centers/vafb/delta-ii-rocket-successfully-launches-noaa-jpss-1-satellite/
  4. Panem et Circenses Thread

    Today at work I was told that I should be a Patriots fan since I grew up in South Jersey and they're the logical team for people in New Jersey to be fans of. After I told him that Philadelphia and New York exist, he told me that everyone in New Jersey should be Giants/Jets fans because they are "actually New Jersey teams". Also the Patriots are not actually connected with Boston in any way because they are the New England Patriots. (also baseball isn't a real sport because there aren't salary caps) (and NFL championships before the super bowl aren't valid)
  5. This thread is for discussion of modern (including Cold War) tank destroyer and gun carrier concepts. Most of these feature a good sized gun on a relatively light chassis with good mobility (as a result, they are sometimes known as light tanks). Some are built on converted IFV chassis. Examples include;
  6. Get Away, Damnit. (The Camping Thread)

    This is a pretty interesting article; https://www.outsideonline.com/2164446/leave-no-trace Wonder if a few of the people "missing" were intentionally trying to disappear?

    Randy Johnson gets owned by a random relief pitcher
  8. I don't remember Huntsville being like that at all though! maybe it's an outlier
  9. I'm not sure how allegations of statuatory rape would make somebody more likely to vote for a candidate, but maybe that's why I'm not a pollster.
  10. Trade-offs in WWII Fighter Design

    Looks like they considering putting a variable incidence wing on the 335 at one point, which is one way to get around the rear prop clearance issue. Don't think I'd trust 1945 German engineering on that though.
  11. Panem et Circenses Thread

    ahahaha Notre Dame and Georgia lost holy shit yes
  12. Two minutes in, but if you're getting owned by the Michelin Man you fucked up hard.
  13. Just played pubg for the first time in months (while drunk) >jump as early as possible, land on stalber >get M16A4 and pan but only 5 bandages >continually get circlefucked >end up with about 2 health >die after doing 4 damage >rank 17 10/10, would play again
  14. Trade-offs in WWII Fighter Design

    The 110's issues were definitely compounded by the rear gunner and all the weight that that added (which the F7F and P-38 didn't have). I wouldn't call the Whirlwind a success, but that's because it was handicapped by its engines, not any glaring design flaw that I can think of.
  15. Rumor has it that in the newest CoD game, Shermans are incapable of penetrating Panzer IVs at any range. fuckin lmao
  16. Aerospace Pictures and Art Thread

    Looks like a graphic designer tried to make a plane. Is that little central pod supposed to hold the engines and the gearbox for those props. Or are the engines in those pods?
  17. Trade-offs in WWII Fighter Design

    Could you elaborate more on the difficulties associated with a setup like the 335? I imagine cooling the aft engine would be a big one. That engine layout seems like a pretty ingenious way to minimize frontal area for a twin, while also improving roll rate.

  19. By now everyone's probably heard that North Korea's probably got their nuclear weapons small enough to fit on an ICBM; https://www.washingtonpost.com/world/national-security/north-korea-now-making-missile-ready-nuclear-weapons-us-analysts-say/2017/08/08/e14b882a-7b6b-11e7-9d08-b79f191668ed_story.html?utm_term=.9e27bcd93746 That article gives an upper bound of 60 warheads (most other sources I've seen are lower, around 20-25). That's more than one for every state! Is America in existential danger? The answer is no, not exactly. 60 warheads is nothing compared to our own arsenal, or what the Soviets had pointed at us back in the day. Assuming each warhead kills 200,000 people (probably an overestimate, North Korea has not yet developed hydrogen bombs, and they are probably reserving a significant amount of their warhead for use against South Korea / Japan / ground forces on the Korean Peninsula) that's 12 million deaths. That would be by far the worst tragedy in American history, and would have massive effects on society as a whole, but it is only a small percentage of our population (ballpark 4%). France about the suffered the same proportion of casualties in World War 1 and won, while Paraguay lost 70% of its male population in the War of the Triple Alliance and still exists nowadays (albeit with less territory than before). Now that I'm done channeling my inner LeMay, what exactly can we do about North Korean missiles? I'm going to discount a preemptive strike; finding road mobile missiles is hard as shit, and any attempt to do that would almost certainly result in a war that leaves thousands if not millions of Koreans, Japanese, Americans, and others dead (this is bad). Here's a great circle route from Wonsan (city on North Korea's east coast) to Albany, one of the farthest northeast targets likely to be hit. (being an asshole, Kim Jong Un will not use one of his warheads to cure America of Patriots fans once and for all) And here's a route from Wonsan to San Diego, about as far southwest as you can get in CONUS. (interestingly enough, the difference in range is only about 700 miles or so) You'll notice that both trajectories fly pretty near Alaska (most trajectories to the middle of the US will actually overfly the state). Clearly, if we want to intercept North Korean missiles, that's where we should put our defences. Boost phase interception is logistically tricky and relies on parking your weapon system right near a nuclear armed country. Terminal phase interception requires you to put a whole bunch of interceptors near any likely target, which just isn't worth it for 60 (probably more like 10) missiles. The US military, not being entirely run by morons, has put their existing missile defenses in Alaska already; https://en.wikipedia.org/wiki/Ground-Based_Midcourse_Defense However, that system has had a mixed record in tests. However, it is getting better, and it probably our best option in the near term for defense against missiles. You can make the problem easier by not requiring a direct hit on the North Korean missile to kill it. Now, instead of having to hit a target travelling at hypersonic speeds with another chunk of metal at hypersonic speeds, you can just get sort of near it. We had that problem solved back in the 70s (though a modern version would need a bit more range to cover all trajectories at midcourse). Of course, detonating 5 megaton warheads in the upper atmosphere opens up a whole political can of worms and other issues and makes people unhappy and oh god it's such a pain. Good luck dealing with that.
