  1. What is that gigantic tube attached at the front? That is not on the bare AN/PVS-2.
  2. Maybe an interesting point here - Czechoslovakia operated 10 Me-262 after the war - seven S-92 (A-1a) and three CS-92 (B-1a). These planes were all built post-war - partially from wartime material, partially from newly produced parts (a lot of those were produced in Czechoslovakia already during the WW2). Four were made of unfinished airframes (LBB production), the rest from planes found on various airfields. Surprisingly they weren't many despite the fact that most of the remaining Me-262 units fought from airfields in Bohemia at the end of war. The planes were partially destroyed by fighting
  3. Elta won Slovak tender for new 3D AD radars (medium, short, very-short range). Slovakia will buy six ELM-2084M-MMR, five ELM-2084S-MMR and six ELM-2138M. After Czechia and Hungary it's third Central European country which decided to buy Elta radars (logically all three neighbours can share certain part of service, training and mainteanance). https://www.armadninoviny.cz/slovensko-nakoupi-17-izraelskych-3d-radiolokatoru.html
  4. GSh-30-2 brrrrrrr (no idea where the video was taken)
  5. USS Georgia filmed by Iranian helicopter near the straight of Hormuz where Iranians hold navy excercise. For some reason sailing only on periscope depth giving Iranians nice chance to track it and gather data such as accoustic profile.
  6. How is it supposed to work? That's purely secondary property and hardly a reason to carry it. The reason for slat armor existence is increase of surivability for the cost of extra weight, ridiculous dimensions, worse driving performance and harder accessability of most of the vehicle area. However it works only against very old HEAT grenades and only sometimes. It doesn't work against ATGM and newer RPGs at all (even against pretty old ones like RPG-18). When the vehicle is equipped with APS, which can deal with all those threats much better, there is no reason to dimini
  7. Why to install slat armour on a vehicle with APS? Slat armour severly degrades vehicle mobility and somewhat protects only against very old anti-tank weapons which shall be an easy prey for the APS.
  8. Some recently uploaded very rare footage from Czech Institute of military history. It's Czechoslovak team from 1937 Zürich Air Show. Four Avia B-534 reached second place in all air racing disciplines behind Germany (Bf-109B) but ahead of other teams (France, Italy, UK, Belgium and maybe some more). One of the pilots was František Peřina who later became the first Czechoslovak fighter ace of WW2 flying as a number two of French squadron leader Jean Accart in the famous CG I/5 "Cigognes". He shot down up to 14 German planes (12 confirmed, 2 probable) before being badly injured over Paris (he man
  9. When You posted this vehicle... do you know guys this thing? It's firefighting tank SPOT-55 based on T-55 chassis and produced by VOP-25 factory (now only VOP) in Czechoslovakia since 1991 (and Czechia after 1993 split). This tank has been in active use in basically every major fire in our country (forest fires, ammo dump accidents, chemical and ammo plant accidents etc.). It's big advantage is that it's optionally manned and can be operated remotely up to 1500 meters from the operator. Unfotunately I don't know how many were built but at least two are also in Saxony, Germany.
  10. Regarding the turn rate/climb rate question... I tried to find some info about bi-planes becase before WW2 those were generally rated to have high-climb rate combined with great turning abilities. I found following numbers (without guarantee): Fiat CR.32 (1934) 9,2 m/s; Gloster Gladiator (1937) 11,5 m/s; Fiat CR.42 (1938) 11,7 m/s; Grumman F-3F (1936) 14 m/s; Polikarpov I-15 (1934) 14,3 m/s; Polikarpov I-153 (1939) 15 m/s; Avia B-534-IV (1937) 15 m/s; Avia B-634 (1936) 16 m/s (not produced aerodynamically cleaned version but still with fixed gear).
  11. Azerbaijan also released updated numbers.
  12. IRGC using Krasnopol laser guided rounds in Syria. They use D20 howitzers to fire them.
  13. Sorry for being late to the party but I found it interesting that the to my knowledge not a single serial vehicle, prototype or concept coming from ČKD (BMM) or Škoda during the war had interleaved wheels (not even any paper project). In the end only one of those designed during the war made it to serial production - the Pz.38(t) n.A. chassis used on Panzerjäger 38(t) Hetzer (albeit the design was somewhat affected by the deliberate effort of ČKD chief designer Aleksey Surin to sabotage it, especially the early vehicles). It's notable that the companies had German management installed to overs
  14. 10 Tu-160 and 12 Tu-95 seen on this satellite photo of the Engels airbase.
  15. If I understand right, it's 1972 preliminary test fire result, i.e. many years before the final specification of the tank was set, right?
  16. Another batch of trips from last fall. Labe (Elbe river) near Terezín fortress (and WW2 concentration camp) after heavy rains. On the horizont on the left side there's Házmburk castle. Jince town with military training grounds in the forests behind as seen from Plešivec hill. Brdy highland, central Bohemia. Křivoklát highland near Beroun, south-west of Prague. Morning mist loosing the fight with the sun over the Labe (Elbe) river near Děčín city. Buková hora mountain with TV tower is visible on the horizont.

    Something new from Iran
  19. On the 3D model it looks like something of 20 mm calibre or so, definitely not 35 or 40 mm. For the larger calibre IMHO the ammo capacity is a big and real problem. TBH I don't think it's a good idea at all to place a medium calibre coax on a tank.
