Bomber Harris, not a happy man (6)

In his excellent book, “The Relentless Offensive: War and Bomber Command”, Roy Irons is not slow to reveal the fact that it was absolutely typical of the attitudes of the RAF in the 1920s and 1930s to have carried out absolutely no research whatsoever on new bombs for the any future war. No attempts whatsoever were made to produce a very large bomb of a very high standard that would do the enemy very real harm. Instead, bombs, quite simply, did not ever change and new aircraft were designed just to accommodate the old bombs rather than to carry a four thousand pounder, an eight thousand pounder or even a twelve thousand pounder, bombs which were  actually quite simple to produce. Here is the 4,000lb “cookie”:

And the 8,000 lb cookie, made by joining two 4,000 pounders together, with a large spanner and a few nuts and bolts:

And the 12,000 pounder “cookie”, produced in pretty much the same way:

Thin skinned and full of high explosive, this was one of the earliest “blast bombs”. None of the three would fit into any of the old bombers without modifications.

Here are the old style bombs being put into the bomb bay of an antiquated Armstrong Whitworth Whitley. Even the tractor looks tired:

The real issue, though, was the incorporation of aluminium into the explosive mix of British WW2 bombs. The addition of aluminium as a fuel for the explosion really makes things go with a bang, as you might say. The Germans knew all about this, and all of their bombs contained aluminium, and could be up to 80% fiercer than a British bomb of the same size.

Harris was continually incensed about the way different groups in the civil service and the armed forces would rather fight each other, than the enemy. This statement is totally typical of Harris’ opinion of civil servants:

“individuals in civil service departments seem to be fighting a different war, if indeed they are fighting a war at all.”

The aluminium in bombs is a fine example. The Royal Navy had known all about it since the beginning of the First World War in 1914. So had the army, who used aluminium based explosives to blow up Messines Ridge in 1917. In this case it was ammonal:

But neither they nor the Navy had bothered to tell the fledgling RAF, perhaps because they wanted to cause the new force harm in any way possible. Harris complained of the:

“failure of communication between departments responsible for strategy, for raw materials and for research”.

As far as the latter is concerned, by the second and third years of the war, there was such a shortage of aluminium that the RAF was unable to carry out hardly any research at all. Only by late 1943 and 1944 were aluminised bombs being dropped over the Reich. Churchill himself said that it was all the fault of the Static Detonations Committee. Their role, admitted Churchill, the Prime Minister, was

“More static than detonating”.

Exactly the same kind of problems with lazy, self centred civil servants was encountered with incendiary bombs. Four million incendiaries were dropped per month, but completely separately. Falling from four or five miles up, but weighing only four pounds, they could fly or glide literally miles from the target. There was absolutely no control over them:

The problem was that a cluster bomb of some kind was needed. A weapon that would weigh perhaps 12,000lbs and contain 3,000 incendiary bombs. It would be dropped from 20,000 feet and release all of its little fireflies at 5,000 feet. Harris asked again and again for the weapon to be developed but by May 8th 1945, the government departments had done absolutely nothing and cluster bombs of this type were never used during WW2. Nowadays they are banned by the majority of countries:
