What do you think might have happened if it had been HMHS Aquitania that hit the mine instead of HMHS Britannic?
Would Aquitania have survived the blast?
If she had sunk what effect on Cunard?
With Britannic surviving the war does White Star survive as a company with two of its Olympic class around?
1. Unlikely if it is the same circumstances, ie open watertight doors+warping from the explosion
2. They are down two big ships, they may end up with Bismarck? Otherwise, they will probably have to accept a smaller ship ala Homeric, which will hit their profit margins somewhat
3. Yes if they get Majestic too, otherwise possibly even worse if Cunard has two of Ballin's trio rather than one. They may build Oceanic III early in such a scenario in order to compete, because otherwise Cunard has three ships that can keep to the schedule, two of which are larger and more luxurious than the Olympic class, even if Olympic is brought up more on par with Britannic where they can. Do they survive in the long term? Hard to say, probably not if Kylsant takes over. He had some decent ideas but he was basically draining the company's profits to prop up his conglomerate, mainly made up of ageing ships. the late 20s was the wrong time to be trying something like that. On the upside, if they have an earlier Oceanic she'll be finished so perhaps.
If they limp along with Olympic, Britannic and Homeric you end up with a similar situation to otl I would think.
