Some food for those wondering thoughtfully why youse Brits have carriers:
British Aircraft Carriers Return Aug 2017 Norman Friedman
"...What the carriers and amphibious ships mean for the United Kingdom is that it can—when needed—operate independently. British national interests may demand that independence. Britain’s view of what matters abroad at times will differ from that of its allies. The ability to operate independently may generate desired support from other countries, including the United States. Without it, Britain’s pursuit of national interests overseas is limited and will depend on the permission and assistance of others.
Most of the world’s population lives and works not far from the ocean, on which most global commerce moves. The U.S. Navy’s post-Cold War littoral strategy was based on those facts and is still valid today. Great Britain let its navy—especially its power projection capability—atrophy after the Cold War. The addition of the Queen Elizabeth and Prince of Wales—armed with F-35B fighters—marks an important milestone in the return of the Royal Navy and its ability to project British national resolve."
