I think this is true of Enigma as of start of WWII. But Enigma was modified many times over the duration of the war, needing not just "number crunching" but genuinely new methods.

So Enigma was genuinely re-broken, a few times, at Bletchley Park, indeed by an all-British team, but yes, easy to forget the little people who did all the initial work.
