Aboukir, Cressy, and Hogue would probably still be lost to a submarine in this scenario, preserving the Royal Navy's fear of underwater attack. Tiger Cubs would inherit more modern internal subdivision and organization from HMS Tiger's design era. Those features would improve their prospects of surviving a torpedo hit. The Navy could gain a more resilient cruiser force while retaining its historical operational caution about submarines.

The Cressy losses still drive submarine caution
Tiger Cubs would not save Aboukir, Cressy, and Hogue, but their newer subdivision might make the replacement cruiser force more resistant to torpedo damage.
