AWE - and proud of it

For over 60 years the AWE name has been synonymous with science, engineering and technology excellence in support of the UK's nuclear deterrent.

1940

Otto Frisch and Rudolf Peierls, working at the University of Birmingham in the UK, considered the possibility of fast fission in uranium-235. Their memorandum was submitted to the Committee on the Scientific Survey of Air Defence.

Fission had been discovered in Germany almost two years before and since the Spring of 1940 they had been conducting uranium research.

1941

In March 1941 a report was produced by the MAUD Committee describing the importance of fast fission for bomb design. This was sent to the Uranium Committee in the USA.

1941

On 15 July 1941, the MAUD Committee approved its two final reports and disbanded. One report was on the “Use of Uranium for a bomb”; the other was the “Use of Uranium as a source of power”. British nuclear weapon research begins under codename Tube Alloys.

In October 1941, the final report draft was presented to President Franklin D Roosevelt who ordered the National Academy of Sciences to support a Bomb Project. The led to the creation of the US Manhattan Project.

1943

The Quebec Agreement between the UK and US is signed by Winston Churchill and Franklin D Roosevelt in Canada. The UK joins the US Manhattan Project.
