Interior of the Fatman bomb. Thanks to en:User:Fastfission for the precious information about the design and plans of the bomb.

Done with Inkscape 0.41.This is really not supposed to be accurate (the interior is still classified) but it gives a rough idea of the main parts of the implosion bombs (Gadget and Fat Man).

  1. AN 219 destruct fuse
  2. Archie radar antenna
  3. Plate with batteries (to detonate charge surrounding nuclear components)
  4. X-Unit, a firing set placed near the charge
  5. Hinge fixing the two ellipsoidal parts of the bomb
  6. High explosive pentagonal lens (12 units around the core, made of high and low velocity explosive)
  7. High explosive hexagonal lens (20 units around the core, made of high and low velocity explosive)
  8. California Parachute tail (aluminium)
  9. Dural casing, ~140 cm inner diameter
  10. Cones that contained the whole sphere
  11. Explosive lenses (low and high velocity)
  12. Nuclear material (see other figure for details about the different layers)
  13. Plate with instruments (radars, baroswitches and timers)
  14. Barotube collector
