Buying aircraft is not building a capability

Possessing a few aircraft let a navy claim participation in aviation, but a purchase did not create an operational capability. Officers still had to decide whether a machine suited their missions, doctrine, support arrangements, and local conditions. Many smaller efforts amounted to keeping a place in the field without resolving those questions. Japan first bought aircraft from France and the United States because those countries appeared to lead development. By 1914 Japanese attention had shifted toward British manufacturers as French industry proved unreliable and American designers pursued less useful paths. The changing supplier map shows how rapidly navies revised their judgments during aviation's experimental phase.
