Useless missile defense

Previous posts showed F-35 obsolete

  The idea of stopping an incoming warhead with interceptors should not work.  As far as I can tell a warhead weighs about 200 lbs (100 kg).  Aluminum weighs 150 lbs per cubic foot.  For the weight of 1 warhead 1.33 cubic feet, 2300 cubic inches of aluminum could be substituted.  If the aluminum is 1/16 of an inch thick (1.5 mm), and the pieces are 4 by 8 inches (100 X 200 mm), over 1000 pieces could be substituted for 1 warhead.  The pieces would be irregular in outline and bent to maximize radar return.  They would be stacked in clusters with a small amount of propellant, solid  rocket fuel, between each piece.  During the ascent the clusters would separate and the fuel would be ignited, separating the pieces.  Each piece would be bright, shiny, and hot to make it easy for the interceptors to see the pieces.   The warhead would also be made with a bright radar return.
   There is a thought that the way to by-pass the defense is to lower the radar signature to make it hard to track.  The better solution is to hide a tree by planting it in a forest.  Give them lots of targets to shoot at.  By having over a thousand potential targets, it would be statistically very unlikely for the actual warhead to be intercepted.  Building a rocket with a throw weight of 2 warheads is somewhat more difficult than building one with a throw weight of 1 but it is not an overwhelming difficulty.  The missile defense system has never been adequately tested and probably would never work.  If an opponent has the sophistication to build a warhead and a rocket, they can also build a warhead and rocket with a thousand decoys.
