  1. This would make a fun design-a-tank competition.
  2. Another lithium SSK joins the east-asian arms race: https://www.janes.com/article/85421/south-korea-completes-preliminary-design-for-second-batch-of-kss-iii-submarines With the japanese launching one this year, I'm sure it won't be long before china gets one in the water (wouldn't be surprised if lithium batteries were fitted to that weird sub with a tiny sail that showed up recently). The battery chemistry would suggest an order of magnitude increase in submerged range is possible, and given that batteries can be refilled underway I expect to see lithium based subs (SSL's?) replace AIP systems quickly. Not having to store strong oxidisers on board the submarine is another plus, those things have a long history of being lethal to the wrong side.
  3. Wouldn't you still need something stout to confine the propellant while it's burning?
  4. Ooh, good point - at longer ranges getting a HE-MP shell and a fin shot on the same target at similar times would be easier
  5. Get a very low velocity MP-HE round, for easier multiple rounds simultaneous impact Hell, stick an 80mm mortar in the turret roof to fire guided airbursting HE. Top attack (so not all APS will see it coming), and it can be used for other mortar things too
  6. That'd be easy to fix with a pair of gears between the engine and transmission, if you wanted to run the thing off a high speed engine. Just a transfer case like the M7
  7. Nothing much new, but it does show the EO sensor on a stick quite well
  8. That's thickness efficiency, not mass efficiency, but a TE of 1/7 is still a mass efficiency of 1.4 (given the density of diesel is ~1/10th steel)
  9. Spare parts would be a very significant cost if you actually wanted to use them, probably worth replacing the engine, transmission and tracks
  10. Is it as much of an issue with contra rotating rotors? There'll be no resultant torque applied, as each stalled rotor will roll you in an opposite direction to the other stalled rotor* * Assuming both rotors stall at the same time
  11. A 40mm plate on a T-72 hull is a significant upgrade, that's >4" LoS
  12. Krakatoa is erupting, and may have caused a tsunami https://www.bbc.co.uk/news/world-asia-46663158
  13. That's an odd vessel - 4.2 MW driving 10k tons is out of the ordinary for ships. I wonder why they decided on a drifting platform, vs a normal research ship? It's not as if russia cannot build icebreakers
  14. There was some discussion of this in the armata thread a few months ago
  15. Following that trend with a polynomial trendline, the Griffin 4 is due to have a -45mm main armament
  16. https://www.janes.com/article/85132/brazil-transfers-m41c-light-tanks-to-uruguayan-army CHAFFEE IS ETERNAL
  17. I'm glad they got rid of the manually operated .50 on top The ladder stowage position isn't ideal if they're planning to fit the usual proper side armour Is that an EO sight on a stick I see, behind the RWS? The UGV in berlin camo is a nice touch
  18. Turns out that pausing the T31e competition wasn't a complete waste of time, as we've had another candidate throw their hat into the ring. I didn't know atlas did full ship design https://navaltoday.com/2018/12/10/three-shipbuilding-consortia-get-funds-for-their-type-31e-frigate-plans/
  19. Meteor missile deployed on ops with typhoon: https://www.gov.uk/government/news/typhoons-launch-with-new-missile
  20. That'd be a whole new level of effort - you'd need to design the shortened gun, test it, work out ballistic data for all natures of ammunition, and reprogram the FCS.
  21. This is how not to do it: https://ascienceenthusiast.com/hawaiian-monk-seals-are-snorting-eels-and-nobody-nose-why/
