Public values for power, timing, distance, or system performance let a specialist use standard engineering relationships to narrow the possible internal design of a ship. Those equations cannot be made secret because many have circulated internationally since the nineteenth or early twentieth century. Classification can withhold inputs and exact arrangements, but it cannot stop foreign analysts from applying the same physics. The practical lesson is that public specifications may reveal more in combination than each fact appears to disclose on its own.

Public engineering constraints can reveal hidden ship details
An expert can combine a few public performance figures with universal engineering equations to infer technical details that a navy never intended to advertise.
