I guess the guidance system would have been based around well tried
and tested modules - hence valves.

I don't know about valves but we were told it used germanium transitors.
(The RAF bod seemed not to have cottoned on that would not impress
teenagers whose trannies were in regular use for Radio Caroline.)


And valves were much better at standing up to the electromagnetic pulse
released by a nuclear explosion...

Thats why the soviets used then in their aircraft!..
