    UAV thread

    Beer replied to Toxn's topic in Aviation

    Yet it's very debatable for what country like Poland could use it. It's very effective for figting a guerilla or a weak military with terrible AD and no airforce but I fail to find an enemy like that for Poland. Countries with modern AD, EW means and airforce are not really vulnerable to slow drones like TB2. People tend to see the success of Azeris through the sexy videos from TB2 but it was loitering munitions and EW which cleared them way. The rest is quality marketing from Turkish side. As for the little green men. In Europe those have been operating stricly in close proximity of Russian borders and Russians didn't really hesitate to decimate the Ukrainean airforce even by cross-border fire. I bet that shooting down combat jet planes is much harder than TB2.

    What kind of different materials? There is number of existing solution for multi-material 3D printing. It's rather commonly available for plastics but you can find metalic or ceramic ones too, albeit I guess that those are crazy expensive. Just google and you'll find a lot of reading about different technologies from different companies.

    I remember seeing somewhere that statistically in Afghanistan or Iraq around 95% of projectiles fired on the vehicles have been RPG-7 hence it still makes a lot of sense to defend against the old threats if those are the far most common ones. The issue is that anything able to stop more advanced rounds is way more expensive than simple slats. In the end if one of hundred RPGs fired is RPG-29 it makes no real impact on the operation even if it sucks for the particular crew whose vehicle was hit by it.

    As N-L-M wrote the principle of slat armor is different, it cuts the fuze of very old HEAT warheads like PG-7 or LAW-66 (I think). There is very little effect on HEAT warhead if it detonates at standoff distance offered by the slat armor. Something like 30-50 cm standoff distance can help if there is heavy tank armor behind but it has basically no protgective effect on lighter vehicles. There used to be a video on youtube of an RPG-18 (which is an old weapon with just 64 mm calibre) easily penetrating a BTR protected by slat armor all the way through in and and out.

    Doesn't Ajax have a manned turret and seven men strong squad?

    It's not a fantastic idea. Not at all. A powerful enough engine is much larger than that box on the picture. Cooling of an engine in front is extremely painful (Izraelis know). The armor protection of the engine is compromised by the size of the engine and by the requirement to make engine and gearbox accessible for mainteanance or replacement (!) and by the need to put exhaust somewhere. The volume requiring heavy protection is larger, not smaller than with the conventional layout, i.e. the vehicle is a lot heavier. Such vehicle would be most likely very front-heavy which compromises driving performance and brings potential issues with suspension or tracks. Driving of such vehicle is entirely dependent on cameras, there is no way to drive it by head sticking out of the hatch even in emergency. Crossing of rough terrain would likely be pretty awkward. Etc.

    I wonder why modern military vehicles tend to have so unnecesarily compicated shapes of everything. To me it just feels very wrong and unefficient design.

    Alleged video of an Azeri Su-25 being shot down by NKR MANPADS. It looks legit to me. https://vk.com/wall-164246427_136938?z=video-164246427_456242646%2F3ede6624ebb3bfb107%2Fpl_post_-164246427_136938

    First photo of the new Czech army modular multi-band jammer STARKOM on armoured Tatra chassis (VHF, UHF, SHF). The army ordered eight systems. It shall be able to jam also various datalinks, missile guidance or drones.

    More photos and video. So far all vehicles fulfilled all requirements. What is left is climatic and EMC tests. Also interesting info about criteria for the final selection. 55% weight goes to the contract price. 30% to technical parameters and 15% to the offset offer. https://www.novinky.cz/domaci/clanek/strelba-i-jizda-tezkym-terenem-vyrobci-v-libave-predvadeli-sve-obrnence-za-miliardy-40361588

    Nice gallery from Czech IFV trials from today (opened day for media) inlcuding a video at the end (some driving and firing). A lot of details inside. Also the competitors were invited to prepare their final bid before the 1st July. https://www.idnes.cz/zpravy/nato/bvp-armada-ascod-cv90-lynx-obrana.A210527_115942_zpr_nato_inc/foto/nahledy#TBR8babef_135356_9542183.jpg

    A Swiss F-5 Tiger II crashed today, pilot ejected. It was a plane of Patrouille Suisse used as OPFOR in a dogfight with F/A-18. The interesting thing is that the crash was caught on photos and mainly that the plane landed in a thick snow staying relatively intact

    Aside of Dana and its derivates (nearly 1000 vehicles produced so not a small production at all) also Swedish Archer has an autoloader. It is in service since 2013 and in development since 1995.
  19. Beer
    Not that I would consider it of any importance but for the sake of facts. Dana - start of development 1969 - first prototype 1972 - first serial delivery 1979 Msta-S - start of development 1980 - first serial delivery 1988

    Correct me if I am wrong but I think that DU can not be used as a structural material welded together with steel. I may have read an outdated info but I found only a diffusion welding with vanadium filler as a possible way how to weld DU and steel together (in relatively small thickness). I doubt it can be used for any large structures such as tank hulls or turrets.
  23. Beer
    Sadly no.

    Not realy breaking news but this is visualisation of Sabrah light tanks which were recently ordered by Philipines (their exact configuration may be different). They ordered 18 vehicles on ASCOD 2 chassis and 10 on Pandur II chassis (plus command and recovery vehicles on ASCOD 2 chassis). The main armament is Elbit 105 mm/L52 gun. The contract is to be delivered by Elbit, GDLS and CSG (Excalibur Army). It is likely that another contract will follow because the initial one was cut down from original 114 vehicles as a part of Covid measures.

    That's seriously childish.
