Keeping the royal dockyards after World War II

What are the advantages and disadvantages if Britain retains its royal dockyards after World War II?

State yards could sustain a steadier building program and cost knowledge, but they would create political pressure to feed them orders and force private yards to modernize or fail.

A retained royal dockyard workforce would have to be paid whether or not a ship was under construction. That pressure could produce a steadier naval building program and preserve public expertise in cost and quality. The Royal Navy would also gain a benchmark when negotiating with private yards. Public yards would need enough orders to justify their existence, however, leaving commercial builders to modernize, compete for merchant work abroad, or fail.
