A DAMBUSTER bouncing 'bomb' has been unearthed on a Kent beach after it was discovered by a father and son where test runs were carried out by Guy Gibson and his 617 squadron crews. Barnes Wallis' Upkeep Bouncing Bomb Recovered from Reculver Bay dropped by 617 Squadron Royal Air Force. Dambusters expert confirms object found on Reculver beach was used before raid. Reculver Beach was used by the crews of 617 Squadron for low-level test drops of the bombs, including a full scale dress rehearsal on Friday 14 May 1943.

Quite the beach find. Great grouping of photos, diagrams and paintings.

I love Harris' letter.

Tried transcribing it and there are a couple words I can't guess at. Can anyone fill them in for me?
------

This is tripe of the wildest _____. There are so may ifs + ands that there is not the smallest chance of it working. To begin with the bomb would have to be perfectly balanced round it's axis. Otherwise rotation at 500 RPM would wreck the aircraft or tear the bomb loose. I don't believe a word of it's supposed ballistics on the surface.

It would be much easier to design a "scow" bomb to run on the surface, ____ it's nose on contact, sink + explode. This bomb would of course be heavier than water + exactly fit existing bomb bays.

At all costs stop them _____ aside Lancs + reducing our bombing effort on this wild goose chase. Let them prove the practicality of the weapon first. Another _____ -- only madder. The war will be over before it works -- + it never will.

Dumb question alert:

I assume the one found was inert, and wouldn't be considered UXO, correct? Hate to see a piece of history that had to be "disrupted" for safety purposes.

Another fantastic post Mark, thank you.

First of all many thanks to Mark Allen M for (again) posting such an interesting thread. I've read about the raid so many times, but I never realised that in addition to flying so low and so steady, the Lancs were carrying bright lights basically telling the German AA gunners on the dams 'This is where you have to aim'. Makes the crews' courage (or bravery) even more outstanding.

Others have tried before, but some just copy mistakes:

At all costs stop them putting aside Lancs + reducing our bombing effort on this wild goose chase. Let them prove the practicality of the weapon first. Another Toraplane -- only madder. The war will be over before it works -- + it never will.


As for the Toraplane, see https://weaponsandwarfare.com/british-aerial-ordnance-exotica/

By the way, I was a bit surprised that an Air Marshal and Knight Commander of the Order of the Bath wouldn't know the difference between its and it's, but apparently he didn't. :-)

This particular "Upkeep" would certainly have been inert. It would never have been intended to detonate as it would have been a proof of concept.
I hope it finds a suitable home. Great piece of history.
I fully agree that this is another fantastic post.

Thank you Mark

From the painting of those guys baling out at ultra low level right over the dam. Did any of them get caught when the dam was breached ?

You'd want to get out of the way pretty damned quick !
