    https://www.janes.com/article/84297/us-navy-considering-re-introduction-of-sub-harpoon Harpoon is really getting old, it's looking like a missile version of the B-52

    Anyone who thinks a tiger 2 was a good tank is bound to favour the impenetrable-even-after-being-surrounded french white elephants over tanks that could actually win battles

    Rocket fuel (hydrazine) is used to stop boilers rusting, by scavenging the oxygen in the heated water

    Mid-30's german motivation was different to german motivation during the war - the other casement designs and late stugs were intended to make the most out of obsolete chassis, but the 1935 stug was intended to provide a mobile 3" (at least more mobile than the horse-drawn stuff used in the last war) that was no higher than an average soldier (so it wouldn't stand out). The osprey book is pretty clear on it being designed to fill a certain role, rather than to make the most from the Pz3 chassis (with a Pz3 gun tank being very respectable for the era), although I haven't read my copy for a while so can't quote page numbers to support my point atm.

    The original stug was custom designed to provide mobile artillery support to fast moving infantry (after all, the original stug gun fit in the Pz3 turret). Later on the stug turned into an effective way to get a long 75mm into the field, but stug is a thoroughbred mobile artillery for infantry support

    Picking 2nd percentile troops is getting pretty desperate

    Open propulsors are meant to be a bit more efficient, which should be useful for an SSK (the extra wetted area of the shroud means more drag). It's interesting to see someone choose to not use a ducted propulsor for a better reason than "it's more expensive than turning the handle on the old design codes for open propellers" Minimising surface area is the main driver for minimising drag underwater, so that means circular cross sections and ducts on propellers are only as long as they have to be - I suspect the extensions on the leading edge of the ducts for the propulsors aren't worth their area
  9. Xlucine
    Wot, no shrouded propulsor? That cover is far too irregular to hide a duct

    2-3 mutually supporting supercarriers is probably in the top 10 largest airforces by numbers of deployable fast jets

    Light tanks for scouting shouldn't be trying to prepare firing positions, they should find the enemy and then get to somewhere where the enemy isn't. Turret means you can shoot backwards, which is a plus (maybe archer was onto something?). Mobile artillery for infantry support is a different thing (stug, SU-76 as Toxn pointed out). If it elevates you can put the M3A1's stabiliser on it* *some assembly required

    Getting people to sell semi-innocuous stuff like car registration databases seems to be a very effective tactic for finding russian agents Jeez, it's a shame the perp offed himself before the cops could get him. Why do US universities have their own police? Anything like this in the UK would be the responsibility of the proper police

    The resonances in the shafts would have been an interesting problem to deal with

    Direct vision blocks? in 2018? The swing down cover is cute, I guess it's just there to stop the glass from getting cracked by rocks and such?

    There's a lot of interest in hydraulic transmissions for wind turbines, although I don't know how widespread they are. That's very high torque low speed continuous-ish operation (probably easily continuous over several hours, which is more than long enough for heat to be an issue).

    Check out the third pic - I haven't seen an open stator/rotor combo on a sub before, I like it I've also seen this concept from euronaval 2018: I would like some of their drugs

    I'm not convinced by AIP systems, they're a bit naff (enough for a couple weeks at ~4kn per janes, and then you need to go back to port to refuel) and strong oxidisers on submarines have a long history of killing people - I can see why aus wouldn't want one on their subs. Li batteries would also add a lot to the cost, you could easily be looking at hundreds of tonnes of batteries on board (and that'll need replacing in a few years). IMO a big RTG is a much superior option for low speed, if you can't get a full SSN, but it would cost a lot No vertical launch at all? Odd, I don't see how space for a VPM precludes ASW capability

    The "modern batteries" dig is a little harsh, given that AFAIK japan is the only nation to improve on lead-acid (and then only recently): https://www.janes.com/article/83625/japan-launches-first-soryu-class-submarine-equipped-with-lithium-ion-batteries The whole procurement is a joke though, they're costing twice what an astute boat does

    COMMONWEALTH T26 USER GROUP GO. Are the canucks using S2087 like the UK & Aus, or do they have their own solution? A common sonar system over 3/5 eyes sounds handy. This takes the number of T26s and derivatives to 32, which is significantly more than FREMM (unless the US buys it)
  21. Xlucine
    Don't forget the BMPT, that has 3 crew in the hull and is more likely to be designed to a similar armour basis as a gun tank
  22. Xlucine
    The F-35 behind them has a paveway on one of the wing pylons

    I wonder how big the cab le is between the seeker and autopilot? Obvious solution is to stack the missile seeker-fins-autopilot to get the fins closer to the nose, so there must be a good reason they didn't just do that
  24. Xlucine
    Ooh, I hadn't heard of that one - thanks (should be the playlist for the whole documentary)
  25. Xlucine
    "rolling". It looked pretty vertical, I guess they'll play with higher speeds once they're more comfortable with it
