Public military specifications and the limits of a discussion rule

For current ships and military equipment, the discussion uses publicly available figures even when a participant believes more accurate information exists. Wikipedia and reference books provide a shared set of published specifications. This convention is intended to keep a technical discussion away from information learned through restricted work. A participant explicitly adds that appearing in public does not always make a disclosure defensible in a US court. The exchange presents a practical discussion habit with that limitation, rather than an assurance that every publicly visible document is unrestricted.
