  1. I have read that Kornet does something similar to avoid the missile hitting obstacles on the way to the target.
  2. Have you ever thought that the ideal shape for an anti-ship or anti-tank missile is a large, angry sphere? https://patentimages.storage.googleapis.com/f1/72/89/634aacb6736f87/US3045596.pdf Well, neither has anyone else since the 1950s. Enjoy this bizarre patent.
  3. I don't see how this is a problem. What's the risk; that the Australians carve out the core of their own submarine to make a bomb?
  4. Clearance during powerpack removals may also be a factor.
  5. Hi, welcome to SH AriesV. IIRC, the equations for estimating performance of long rods against homogeneous armor include a fractional exponent on the inverse cosine of the obliquity. Long rods normalize into sloped armor significantly, and you can actually see this in some test pictures: So I would expect a monolithic sloped armor to perform less efficiently than a flat one vs. APFSDS. A series of spaced, sloped plates might be a different story. As I understand it, it is very difficult to get APFSDS to ricochet. Exact angle at which ricochet occurs is a fairly complex question which involves the density and moment of inertia around the long axis of the penetrator as well as the hardness and probably elastic modulus of the armor, rather than just a fixed angle. As APFSDS penetrators have gotten ever greater aspect ratios and switched from steel to tungsten/uranium, it has become correspondingly harder to make them bounce.
  6. Tests of aluminum/steel composite plates by the US in the 1930s: https://apps.dtic.mil/sti/pdfs/ADA953774.pdf
  7. A quick search didn't turn anything up, so I apologize if this has already been asked before. Most sources credit the Leo 2's hull ammo rack with 27 rounds, in a hexagonally packed arrangement of two rows of six rounds and three rows of five rounds for five rows total. This is illustrated schematically: but actual photos show only 22 rounds, with four rows alternating six and five like so: What gives?
