Radar hardware of one design and a good one was developed in the UK.
Western Electric was assigned to take it and make Ship radar and
then Air radar. The design team was in Bell Labs, my dad was on
that team.
He later went to Carolina to put it into production. He retired as
a
director of R&D in Field Engineering and had a heavy dotted line
back
to Bell Labs. He spent his last 6 months in the Labs completing his
design documentation on his last monster Radar.

The US worked on radar at the same time, but didn't have a working
model
as clean as the UK. The UK design went to both Naval bodies of the
UK and USA. It was critical for the shipping between the US and the
UK. Later it was shown to be instrumental in many a battle in the
Pacific.

The Magnetron tube that was provided was an R&D design by the UK. It
put
both of us ahead in shipboard radar to fight planes and subs.

The magnetron tube was an American invention:

The British contribution was to extend its frequency response into the
microwave range.
US experimental microwave radars of the late 1930's used Klystron
tubes, which took longer to fully develop.

That article mentions that magnetrons had poor frequency stability.
British electronic genius R. V. Jones wrote that they could classify
unknown transmissions as British or German by observing their
frequency stability. Typically German field gear was as good as the
best British laboratory instruments.
