The Queen Elizabeth class demonstrates that diesel and gas machinery can remain useful in a very large carrier. India's COGAG arrangement combines gas turbines configured for different operating conditions. General Electric LM2500 turbines are recalled as the Indian machinery choice. Chinese carriers use oil-fired steam in this comparison. For a future Chinese nuclear carrier, retaining steam machinery provides continuity because nuclear propulsion also uses steam.

British, Indian and Chinese carrier propulsion choices
Carrier size permits several propulsion arrangements, and the expected future fleet can influence which machinery a navy retains.
