    Armoured decks make sense if you're expecting your carriers to get dogpiled by land based aircraft (which come in numbers way bigger than any carrier air wing, so if you squeeze as many AC as possible on board then they'll still outnumber you, and carry bigger bombs). The pacific is not the med, basically A 500 lb bomb is a Very Bad Day for an unarmoured carrier (e.g. yorktown at the battle of the coral sea), whereas armoured carriers were surviving 2000 lb bombs regularly

    Tank engines are around 1 MW ea., so assuming a 1:8 ratio of time spent moving to time spent recharging then you need to suck 8 MW from the transformer per tank in the convoy at 100% efficiency - and that's assuming the power grid still works reliably, it was one of the first things to go in the iraq war. It is really a diesel engine at that point? It sounds more like a high compression otto engine, with the spark plug swapped out for an injector (and if hydrogen acts like a high octane fuel, improving on efficiency isn't that unexpected - although under part load it'd have to revert to act like a normal diesel). The defining feature of the diesel cycle is that there is no fuel mix, combustion only occurs at the boundary between the injected fuel-rich diesel droplets and the oxygen-rich rest of the air in the cylinder so there shouldn't be any diesel floating around the combustion chamber to be ignited by hydrogen. Sub-ambient intercooling could run into issues with condensation getting ingested into the engine

    That's interesting. I've seen some work on freak waves previously (as in ~15 years ago), but that was looking at 2d waves where one wave would suck energy out of the waves either side of it - building on the work in a 3d pool is neat

    UAV thread

    Xlucine replied to Toxn's topic in Aviation

    The total weight is <33g, so maybe a small firecracker? Small-ish suicide UAVs have been done before, of course

    Leclerc has been used as a platform to test a 140mm gun: https://www.janes.com/article/85934/iav-2019-nexter-tests-140-mm-gun-on-leclerc-mbt

    I feel sorry for those berets

    The system for transmitting launch codes to the SSBN's is entirely sovereign UK, we aren't piggy-backing off the US PAL system. The only obvious way for the US to impede UK nuclear weapons would be to deny maintenance in future, which doesn't do much for the ~8 missiles on patrol right now (and if HMG will no longer exist anyway, so what?)

    More lazy reporting https://www.38north.org/2018/11/lsigal111318/ (Old rebuttal, but the grauniad report is practically the same as the NYT article they were responding to) Once Kim agrees to declare their nuclear sites, then that'll be worth reporting - having operational capability isn't breaching any agreements.

    If it's just there to cover some soft foam for crash purposes I bet they could just as well have used some vacuum formed plastic at a lower weight, but that wouldn't have the carbon/aramid a e s t h e t i c

    Bigger, armoured bustle would add weight, no? And rolled plates (especially modern rolled plate) is more mass efficient than cast armour? So the new welded turret could be to free up some weight margin for the bustle stowage, if they have it for the new gun. Given the lack of step, they're either proposing a massive reduction in roof armour thickness or a new turret. The positions of the turret crew are unlikely to have changed, why would the loaders periscope or gunners sight show up in a different location?

    This scenario shouldn't feature in the SDSR, because any proper invasion of the UK (i.e. an existential threat) would warrant a nuclear response and no-one wins. Any threat nation invading just the UK would be an odd move, and would have to contend with almost every submarine in NATO en route (who've been salivating for a chance like that for decades).

    Must be very futuristic if they're considering a hovertank. The hologram showing the 3d model is a neat touch

    I agree, ABS sensors normally do double duty to run the speedo. The problem is that the plug broke, snapped in half. Now the hole is permanently plugged. I either I drill it out and tap a new thread, or I just replace the entire thing. Its only a L shaped metal piece, so I might find the part laying around. A left handed drill might get it out

    Unless it's carrying more hull armour

    I like the glass boot lid, reminds me of the recent volvo hatchbacks (which I guess were copying this)

    Looking through that report linked, I'm pretty sure they've used a photoshopped image. Check out page 81 - the amphib vehicles in the background look awfully similar. Reverse image searching it shows up the same 'shopped image all over the place, so I think it got attached to an AFP news item. Here's an example of a typical report using it: https://www.scmp.com/news/china/diplomacy-defence/article/1996073/china-russia-hold-joint-naval-drill-south-china-sea This is very off topic, I know ETA: I just noticed that that AFP news item credited the image to Xinhua news agency.

    Remove the flooring tiles, cut into shape the heating mats, add a power cord and heat sensor, and hook it up to a thermostat. Then re add the flooring. Not very expensive at all. Besides, who uses water borne floor heating outside of eco houses? Is electric heating for the whole house typical in norway? Gas in the UK is several times cheaper than electricity (like 5p/kWhr compared to 15 p/kWhr, which makes sense given how a significant fraction of the power in electricity starts as gas going into a combined cycle plant), so a gas boiler pushing hot water around the house is the normal way of heating houses here

    Interview with UK F-35 pilot https://hushkit.net/2019/01/15/interview-with-a-british-f-35b-lightning-ii-pilot-semper-fidelis-to-semper-paratus/ He likes it, and apparently there's no plan for the UK to buy the gunpod at present

    Did russia get any extended end connectors with their shermans?

    I'm also sure they'll bring their tanker (this is dependent on said tanker being available, and it was overhauled recently so they're likely to want to show it off). If they don't have the training to replenish while underway it's possible to transfer fuel while stationary at sea (even commercial oil tankers can do that, as demonstrated by north korea evading sanctions), so I'm sure iran has the capability to get a few ships to america if they wanted to. Bringing the tanker also means they'll have a helicopter hangar available (AFAIK it's the only one afloat in their navy, which sort of explains their "helicopter carrier" moniker for it) It's nothing to do with demonstrating any kind of military effectiveness, of course

    A one-off deployment to the atlantic isn't too challenging, it's not war so there's plenty of ports to call in. AFAIK there's no sanctions preventing countries from selling fuel to iranian vessels. It won't achieve much, but it should be possible

    Putting a 57mm gun on something intended to support infantry goes back over a century

    Shouldn't add too much parasitic mass to include a timed fuse in the base of an APFSDS, so that just outside the interception range it goes pop and sheds the fins (~100g? The OICW grenades seem to be around that, and it's not much extra weight with several kilos of W). I wonder how early you could do it and still be stable enough when you hit the target?

    WoWS is odd. For new players, you typically get sorted into games with 2-3 players per team and the rest bots. These are pretty easy to play, and it's easy to feel good about your performance (especially if you play aggressively). Once you hit some magic number (possibly number of battles, or tier), you get normal matches with players filling all the slots. This is a fundamentally different game, as players are a lot better than the bots - suddenly the aggressive gameplay that works well against bots just gets you killed quickly. I'm still re-calibrating to adjust for this.
