If the United States and Japan did not receive their battlecruiser carrier conversions, would they build another Langley and another Hosho?
Short answerJapan might build another Hosho-like test carrier, but the United States would probably move to a different design rather than repeat Langley.
NotesLangley was converted from the collier Jupiter, while Hosho was built from scratch as a test bed. Japan might plausibly build another Hosho-like vessel to continue development. An exact American repeat of Langley seems unlikely; a different follow-on design is expected.
