Naval treaties left room for more patrol support

Did the naval treaties prevent the United States from building the patrol aircraft, tenders, and auxiliaries needed for Pacific reconnaissance?

No. Some destroyer and auxiliary limits existed, but the treaties left ample room for more patrol aircraft and aviation support.

Treaty restrictions do not fully explain the American reconnaissance gap. The first London Naval Treaty imposed cumulative destroyer limits, while the second removed them, but patrol aircraft and much seaplane support were not capped in the same way. Some auxiliary categories had rules, yet they still left substantial freedom for reconnaissance investment. HMS Unicorn illustrates how a ship designed as a forward aviation-support vessel could be treated as an auxiliary rather than consume aircraft-carrier tonnage.
