Title: The Disney Bomb
Post by: Weaver on July 26, 2013, 07:22:52 AM
Well here's one I'd never heard of, the 4,500 lb rocket-assisted "Disney Bomb" developed by the Royal Navy in WWII and deployed by USAAF B-17s to destroy U-boat pens:

Would it have been possible for the AVRO Lancaster to carry one or two of these weapons internally on the version with the modified bomb bay doors that was built to carry the 8000 and 12000 pound HC "Block Buster" bombs?

It could certainly carry one internally. Not sure about the clearance for side-by-side, but here's a thought: if the tail cones were made just a smidgin shorter, it could carry two nose-to-tail.....

I don't know this for certain, but I was watching this film today (would highly recommend) and I imagine that this is where the bomb got its name.

Disney's "Victory Through Air Power" 1943.  Start at 1:00:56.

I wasn't aware that B-17s used radar for bombing.  Where was the scanner mounted?  I assume it was H2S?

H2X, antenna mounted in place of ball turret.

In USAAF usage, it was called H2X.

Brian Watkins at Resin2Detail  (http://resin2detail.com)has recently released a number of new detail items in 1:72nd and 1:48th scale.  The one item that really caught my eye this time around was the "Disney Bomb."  This weapon was designed around a very large penetration (armour and concrete) bomb with a battery of solid rocket motors that would ignite after a short delay when the weapon was released from the carrier aircraft.  The rocket motor ignition then drove the bomb at high speed towards the target where the kinetic energy of the weapon would overcome any armor and concrete barriers to explode inside the target structure.  More information on the weapon can be found at Wikipedia - Disney Bomb (https://en.wikipedia.org/wiki./Disney_bomb) if you wish to learn more about this weapon.  Clicking on the image below will take you to the same page.

I would also like to add that after these items were initially offered I contacted Mr. Watkins to inquire about the practicality of selling these things as individual items of one bomb each by pointing out that the carrying aircraft all carried two of the things.  That prompted a reply from Brian to let me know that he has dropped the price ever so slightly to encourage customers to purchase two instead of one to make up for this oversight.  I appreciate this type of response from the maker and it has convinced me to go forward with a purchase of this item and a few other items that are now available at Resin2Detail.

I purchased four of the things in 1:48th scale two weeks ago.  They were delivered last week and are waiting for me to pick up at my brother's place in town.  :)

As far as the delivery platform, who knows for sure what they had planned for delivering the weapon.  It might have been a situation where the bomb was built without consideration to what platform would carry it.  The fact that the USAAf was given the mission and the B-17 was able to carry the things externally does not mean that it was for ever and written in stone that the weapon would be carried internally but perhaps it was with caution that the weapon was carried externally since there were rocket motors in the thing that if ignited inside of a bomb bay might have caused a catostrophic mishap in flight or on the ground.  That the B-17 did carry the weapon and managed to drop it in action says a lot about the versatility of the aircraft.  I do wonder if the RAF would have considered any kind of external rack for the weapon so that it could be carried on the Lancaster under the wing between the fuselage and inboard engines?  Would the racks have been similar to what was mounted on the B-17?  Something to think about and imagine what a Lancaster would look like with a pair of these things strapped to it.
