So the Leclerc wont the South African competition ? How did it win it ? I never heard of that competition until now. Is there any more information floating around out there ?

Here are also seems to be another view of an Abrams turret shell CAD model in the lower right corner of the image: It seems that certain Abrams tank test rigs such as the M1 Thumper used the original M1 turret as a base instead of creating a new turret from scratch.

Thanks for the feedback and additional information. I am trying to figure out what prototype could have been used in 1987. The earliest prototypes besides the 1986 Mulet Systeme Complete (MSC) was the Leclerc Ares prototype. The second prototype, Leclerc Bayard came into being in 1988. Frankly, the Ares prototype is the only Leclerc prototype I have never ever seen an image of in any publication or any other media. I have no idea how that thing looks like. Having said that, in 1987 the only vehicles available for an evaluation would have probably been the MSC (and maybe Ares). As

Here is another diagram to illustrate the idea of the 2 man flat turret design concept being able to use "denser" special armor arrays: Although the modules on both turrets have the same constructive depth, the flat turret design can get away with adding another 3 NERA plates in its special armor array without a volume (really mass) penalty. In this case the flat turret design is even slightly "lighter" (0,176 m3) than the full turret design ( 0,192 m3) while still theoretically improving the protection by 50%.

I was explaining the idea of a 2 man flat turret according to GIAT/Nexter. The illustrations show that heavier(denser) modules can be allocated towards the front of a turret without much or any additional weight penalty. In case of the 3 man turret i might only be able to insert 6 special armor plates where as in case of the 2 man flat turret i can insert another 2,4 for the same mass. I rather go with the 8.4 special armor plate design than with the 6 special armor plate design. These British snippets are indeed problematic because they contradict what has been reported

Very nice work!

Thank you for your reply. Here is my rebuttal: Lets focus on KE protection. The Leclerc Series 1 turret frontal arc protection is rated around 550 mm RHAe against KE projectiles. Where as the Leopard 2A4 equipped with C-Technology armor is rated at around 420 mm RHAe against KE projectiles. The Leopard 2A4 (C) front hull is rated around 400-450 mm RHAe against KE projectiles, where as the Leclerc's seems to be around 500 mm RHAe for the same threat. Sources: Lindström Presentation (Leclerc protection and Leo 2 protection) and declassified British Documents (Leo 2 protection).

The 60 degree frontal arc protection is not as consistent but directly from the front it has its advantages. Having a 2-crew autoloader flat turret design has the advantage that armor can be concentrated and protection improved by up to 74% compared to a 3 crew conventional turret of the same mass. That is what the South Koreans seem to have done. The French did it with the Leclerc to a slightly lesser extent. That also explains why the Leclerc has a similar mass to the Leopard 2A4 yet superior protection in terms of KE and CE resistance. This would also explain to some extent how a 55 ton veh

So E- technology armor packages are not meant to be armor inserts to replace the D-technology armor packages, they are meant just as add-on armor packages ?

Does anyone know when the "E-technology" armor packages were introduced to the Leopard 2 line ? I heard that that happened over 10 years ago.

The Soviet Tank Thread: Transversely Mounted 1000hp Engines
Laviduce replied to T___A's topic in Mechanized Warfare
FYI , concerning the NP 105 A2 round: "Land Forces of the World" (Christopher Chant, 1990, Crescent Books / Crown Publishers / Brian Todd Publishing House Ltd, ISBN 0-517-69128-0), on page 146 the book describes an NP 105 A2 tungsten APFSDS round with a complete weight of 19.3kg (mid-1980s Jane's A & A suggests a penetrator length of 980mm and penetrator weight of 3.7kg Tungalloy T176FA) and a muzzle velocity of 1485m / sec, giving 150mm @ 60degrees @ 5800m performance (almost 6 inches at just over 3 & 1/2 miles). And the glacis of that T-72M1 was able to stop this round- 4,575 replies

The Soviet Tank Thread: Transversely Mounted 1000hp Engines
Laviduce replied to T___A's topic in Mechanized Warfare
I was aware of that and did take into account. I was just surprised that the rated value against APFSDS threats and the given penetration value were off like that. Just like in the case of the Swedish tank trials I would expect to be given resistance figures or at least a certain range with a given margin of safety.- 4,575 replies

The Soviet Tank Thread: Transversely Mounted 1000hp Engines
Laviduce replied to T___A's topic in Mechanized Warfare
I read that the NP105A2 has the ability to penetrate 470 mm RHA at 1000 m. How was it not able to penetrate the glacis ? I thought the T-72A/M1 hulls had a KE resistance rating of around 400-420 mm RHAe not including weak zones. I would expect T-72B hulls to be this resistant but not T-72A/M1 hulls. Can someone explain this to me ?- 4,575 replies

In other news: "Marines to Shut Down All Tank Units, Cut Infantry Battalions in Major Overhaul" In the next decade, the Marine Corps will no longer operate tanks or have law enforcement battalions. It will also have three fewer infantry units and will shed about 7% of its overall force as the service prepares for a potential face-off with China.

Ukrainian armor - Oplot-M, T-64M Bulat and other.
Laviduce replied to LoooSeR's topic in Mechanized Warfare
Not sure if you all have seen this before. This is a chart that shows of the technical details of the BM Oplot tank and VT4 tank. Richard Gao over at the SinoDefense Forum was so kind enough to translate the original chart: I am not sure if about the protection values. According to the chart, the turret front and hull front of the Oplot are rated at: KE(3BM42/OFL120F1)>= 1100 mm** CE(<Kornet-E>) >= 1300 mm** As far as I know, the 3BM42 has the ability to penetrate roughly 500 mm of RHA (260 BHN?) at 2000 m. The OFL120F1 penetrates a -
