What fleet would Britain send to the Far East?

Would Britain form a battlecruiser squadron and carrier force for the Far East?

Yes: fast battlecruisers and a multi-carrier strike force would likely deploy, with Renown, naval fighters, and tactical radar accelerated as resources allowed.

Hood and Repulse could deploy early, with Renown's reconstruction accelerated enough for her to follow later in 1939. Ark Royal, Courageous, and Glorious could form a strike carrier squadron, while Eagle, Hermes, or another carrier emphasized fighters and spotting. A Far Eastern naval war would also shift resources toward carrier fighters, shipboard radar, and tactical air warning because the Navy would lead the national effort. The exact composition remains conditional, but war against Japan would produce a very different mobilization from the escort-centered response to Germany.
