Henderson takes office just after the formal end of the Ten Year Rule, while tight Treasury control still constrains real rearmament. He has to preserve civilian shipyards against a policy that pays them to close and binds them not to reopen, making industrial capacity part of immediate war planning. Long days, late nights, and weekend yard inspections allow him to drive the program forward but damage his health. His death before the war also contributes to a shortage of experienced senior officers, helping explain why commanders such as Somerville and Cunningham later carry such punishing workloads.
