Would Japan have been better building the Fubuki concept as a 2,000-to-3,000-ton fleet destroyer before the London Treaty?
Short answerYes. A larger hull could have made the armament workable and forced other navies to respond with larger destroyers.
NotesJapan could have built the concept as a 2,000-to-3,000-ton fleet destroyer before the London Treaty imposed tighter categories. A larger hull could retain the guns and torpedoes while gaining the beam and volume needed for stability. A successful Japanese design would likely have encouraged other navies to copy or answer it. The American response might have produced an even more formidable path toward the Fletcher class.
