this project was created in homage to Polish mathematicians (Rejewski, Rozycki, Zygalski) who broke the code of the German Enigma machine. In July 1939, the Polish side invited representatives of the cryptological services of France and Great Britain transferred all knowledge about decrypting the Enigma code. Based on the information provided by the Polish side created by the British in 1939, Bletchley Park, enabled Alan Turing to "quickly enter" further work on decoding the Enigma cipher.
In the documentation for the self-made electronic Enigma, there are all pcb prints for thermal transfer.
You're right when it comes to V1 and V2, I recommend the document
however, the most important for humanity was the participation of the Polish mathematician Stanislaw Ulam who, together with Hungarian Edward Teller, created thermonuclear weapons https://en.wikipedia.org/wiki/Thermonuclear_weapon
