Message: <blockquote data-quote="jeffryfontaine" data-source="post: 35322">Iain, Thank you for sharing that image.  Much better than the the only image I have ever seen previously of this weapon.  Knowing the dimensions, I can now attempt to create a drawing with a bit more detail.  As I mentioned in the first post, the only image I had seen previously of the Disney bomb was in color but the weapon was surrounded by several people so there was only a small portion of the bomb visible in the image as it sat on a trolley.  Regarding why the weapon was named the Disney Bomb, I have no idea.  I had thought that it was due to the weapon being developed by someone with that name but according to sources the weapon was designed by Captain Edward Terrell of the Royal Navy.  This page has some supporting reference notes on the Disney Bomb <a href="http://members.aol.com/nukeinfo2/">http://members.aol.com/nukeinfo2/</a> (with many dead image links)<blockquote>The American bombs tested included the fabricated (welded plate) Tallboy (T-10) and fabricated Grand Slam (T-14), the 2,000 lb SAP (M103) and a new 22,000 lb SAP design called Amazon (T28).  The British bombs included the cast Tallboy and Grand Slam, the Disney and the 1,650 lb scaled version of a proposed 12,000 lb rocket assisted concrete penetrating bomb. 34</blockquote> <blockquote>34  The Disney bomb was a ~4,500 lb rocket assisted concrete/armor piercing bomb.  Designed to be dropped from 20,000 ft, a tail mounted set of rocket motors would ignite at 5,000 ft accelerating the weapon to a high impact velocity.   The forged and hardened steel cylinder body with a sharply pointed nose contained about 500 lbs of Shellite (similar to US explosive compostition D).  In the base of the bomb, two British No. 58 Pistol fuzes were mounted.  The tail unit attached to an adapter plate mounted to the base of the bomb.  Two suspension lugs were bolted to the bomb casing.  The tail unit contained 19 3” rockets bundled together weighing about 900 lbs.  Each motor contained 12.5 lbs. of cruciform shaped flashless cordite rocket propellant SU/K/X.  An M111 mechanical time fuze activated a switch allowing electrical ignition of the rocket motors that was powered by a wind driven generator mounted on a conical fairing at the tail.   The bomb was carried on external racks.  Individual pullout wires were used to arm the M111 time fuze, the pistol fuzes and to allow free spinning of the wind generator.  USSTAF Armament Memorandum No. 3-133, 28 January 1945, p. 1-2.</blockquote></blockquote>
