Your comment doesn't seem very grounded. Those two British aircraft carriers were designed in the 2000s and are substantially more powerful than the brand new Chinese one which is a copy of the Russian one that was designed in the 80's. They operate F35's on them which are more modern and advanced than anything in the Russian or Chinese inventories. The closest Russian equivalent, the SU-57 was rejected by the Indian Air force for poor performance and the Chinese one doesn't have good domestic engines. The UK's has been investing in modernizing it's forces even under the budgetary constraints it works with.
