Why the seaplane-tender case lost in interwar procurement

The Air Ministry argued that land airfields could provide greater capacity, echoing its wider objections to naval aviation ships. The Treasury favored the claim that Italy, Japan, and Germany could be contained, because accepting that premise avoided spending on insurance for secondary theaters. Naval advocates then faced a rhetorical trap: admitting that enemy forces might escape containment appeared to concede that the Royal Navy could not perform its primary mission. Containment in the Mediterranean would still leave merchant raiders already abroad and forces in Italian East Africa outside the blockade. Procurement decisions could favor the argument most persuasive to the funding authorities, even when it left fewer options after the strategic situation changed. The result left Britain able to reinforce known bases but less able to shift aviation infrastructure after the strategic map changed.
