Not necessarily true, as the effort to miniaturize the package size for use in ICBM warheads proceeded, they've successively reduced from the "soccerball" style of lenses in the trinity device down to only a handful (it is a design mandate that a bomb retains "one-point" safety in the event that it is detonated by an external source at a single point, but referencing Command and Control here, there have been flawed bomb designs that had a 15% chance of a 40kt yield in an accidental one-point detonation).
