USN would have had to commit much resources if these Soviet carrier ambitions ever became a reality, they didn't but now a new challenge is on its way, the Chinese carrier battle groups
Each Chinese fleet may eventually have one or more carrier which means there might come a time when China has two carrier battle groups sailing in the oceans, this will then require two USN carrier strike group commitments and alot more resources going into shadowing and monitoring these tasks forces
That is where the two new Queen Elizbateh carriers come in, with two carriers assisting from the Royal Navy this would compliment the USN and certainly free up a Nimitz Class and if say France commits a carrier this could free up to two USN carrier strikes groups making up for the two that might be facing China
Having a one Queen Elizabeth carrier and a French carrier in the Persian Gulf or maybe even two Queen Elizabeth carriers on a "surge" would mean 5th fleet would have a extra helping hand freeing up resources for the Pacific Pivot
This is why I think the two Royal Navy carriers will be extremely busy when they are commissioned, doing duties all over the world proving thier worth, the battle of the carriers is due to begin very soon! Well not literally a battle but you know what I mean
