Does this photo show any indication that they are doing night ops?
Those pics certainly show aircraft on deck, all loaded up and spoitted there either late in the day or early in the morning.
Clearly in that one with several aircraft spotted on the stern, any air ops would be going on forward during take offs.
I believe there are better pics or videos out there shoing it happening very late in the day or very earliy in the morning.
But I have not seen as yet anything similar to what we see US Navy or French aircraft doing, or, for that matter what we have seen the Indians doing with their Mig-29Ks at night on their Vikramaditya:
But all in due time.
