Why interwar naval procurement controlled costs better

Why did interwar naval procurement often avoid the cost escalation seen in modern programs?

The Admiralty retained specialist staff, naval constructors, its own yards, and a steady production rhythm that strengthened cost knowledge and industrial continuity.

The interwar Admiralty possessed an experienced internal customer able to challenge industry estimates. Career specialist civil servants and a strong Department of Naval Construction preserved technical and commercial knowledge inside the service. Government yards supplied a real cost benchmark and gave the Admiralty the option to build work itself when private bids were excessive. A steady flow of design, construction, evaluation, and upgrade work also reduced boom-and-bust overheads for both public and private organizations. Procurement performance therefore depended on institutional memory, internal engineering capacity, and predictable demand as well as contracting technique.
