  1. Leopard 2

    The data comes from the Tankograd booklet on the Leopard 2A7 and it seems to contain a few errors (e.g. ground clearance not including the mine protection plate...). The author of the booklet is Ralph Zwilling, who seems to be mainly focused on photography (at least judging by his excellent website). Currently 37 rounds of 120 mm ammunition is normal, due to the shock-proof ammunition rack in the hull taking up more space, eliminating the lowest row (for five rounds) of the previous ammo rack. This is accepted due to the new rack preventing the ammunition from exploding in case of a mine/IED blast. Based on statements from US tank crews, the M1A1/A2 Abrams is often operated without filling the hull ammo rack, so depending on version it has either 34 or 36 rounds of main gun ammo. PS: Qatari Leopard 2A7s
  2. T-80 Megathread: Astronomical speed and price!

    So they use some plastic wrap/cling foil to prevent dust and dirt getting in the gun barrel?
  3. The Merkava, Israel's Chieftain?

    No, it's Elbit ALWACS' VIRCM (Vehicle Infrared Countermeasure). https://elbitsystems.com/media/ALWACS.pdf
  4. The Merkava, Israel's Chieftain?

    Yes, my bad. That happens when someone quotes just a single picture where the optics are covered... the other ones from the previous page make it obvious that this wasn't the topic of the discussion.
  5. The Merkava, Israel's Chieftain?

    Laser warning sensors from Elbit Systems. Also used on other Merkava variants, the British Ajax and the TAM 2C upgrade.
  6. Leopard 2

    "The Singapore Armed Forces (SAF) is continuing to improve the combat effectiveness of its fleet of ex-Bundeswehr Leopard 2A4 main battle tanks (MBTs) with new capabilities, with the most recent addition revealed to be a commander's panoramic sighting system. At least two upgraded Leopard 2A4 MBTs - which are operated by the Singapore Army under the designation of Leopard 2SG - featuring the new system, called the Commander's Open Architecture Panoramic Sight (COAPS) were exhibited in public at the Army Open House 2017 (AOH 2017) event from 27-29 May. "COAPS is part of the SAF's effort to upgrade the Leopard 2SG since 2010," the Ministry of Defence (MINDEF) revealed to Jane's in an 18 June statement. "Other ongoing upgrades include [the installation] of battlefield management system (BMS), crew compartment cooling system, auxiliary power unit [APU], reverse camera, internal vehicle electronics, and fire-control system [FCS] modifications." Singapore Army personnel with whom Jane's spoke to at AOH 2017 said the new sighting system is supplied by STELOP. The company is a subsidiary of Singapore Technologies (ST) Electronics, which is the advanced electronics and communication development arm of local defence prime ST Engineering. However, industry sources told Jane's that STELOP is manufacturing COAPS under license from Israel's Elbit Systems Electro-optics (ELOP), which has been offering the system on the international market since it was launched in March 2010. According to Elbit's specifications, COAPS is a modular dual-axis stabilised sight aimed specifically at armoured fighting vehicle (AFV) and MBT applications. Based on an open architecture design, it can be configured with different sensors, including 3-5 µm or 8-12 µm thermal imagers, day and night charge-coupled device (CCD) cameras, and eye-safe laser rangefinders, to suit mission requirements." - Jane's IHS
  7. Contemporary Western Tank Rumble!

    Oh, that is Georgian? I didn't pay too much attention to this and assumed it was Greek. My mistake resulted from using Chrome (Chrome has a built-in translator, which I use for most languages other than English).
  8. Polish Armoured Vehicles

    So is the PT-16 being considered option (1) or (2)? Or does neither version feature a 120 mm gun + add-on composite armor?
  9. Contemporary Western Tank Rumble!

    Here is something for this topic: A Greek blog entry on their testing of the Challenger 2E, Leclerc, Leopard 2 Improved, M1A2 Abrams, T-80U and T-84 tanks. The scores from the evaluation are the following: Leopard 2 Improved - 78.3 M1A2 Abrams - 72.95 Leclerc - 71.92 Challenger 2E - 69.89 Т-80U - 59.2 Т-84 - 56.3 The google translate output is quite interessting, if correct. Supposedly the Challenger 2E was found to be worse armored (!) than the M1A2 Abrams and Leopard 2 Improved despite being heavier. So much about mighty "Chobham Mk. 2 Dorchester" being the best armor. Even the ten tons lighter Leclerc tank had nearly the same level of protection as the Challenger 2E. The use of the EuroPowerPack in the Challenger 2E is believed by the blog author to not have enhanced the mobility, because there have been issues with power delivery and despite switching the powerpack, nothing else was changed to properly optimize the tank for the different engine (?). The T-80U had issues with the semi-automatic transmission and general reliability, including the weapon systems (guided missiles) and FCS.The T-84 has a weird internal layout and bad controlls, essentially requiring the driver to have "three hands" to work with the steering wheel and operate his other controls. Operating the T-84 was so tiring, that the Greek crew had to be replaced by the Ukranian crew in some tests. Leclerc, Leopard 2 and M1 Abrams had no issues with driving up and down a 60% slope, the other tanks however had some problems. Btw: the Italian C1 Ariete and the Israeli Merkava III tanks were considered, but the manufacturing companies/officials didn't want them to participate in a competition (maybe because they were afraid of these relatively new vehicles underperforming and causing big political backlash). Note that the Leclerc is fitted with additional armor. The Challenger 2E lost most of it's track's pads when trying to climb a wall. Does anybody know if the Challenger 2E used the same tracks (by Cook Defence) as the British Army model? Did the greater powerpack cause these issues?
