I still have not received an answer from golly about the fueling system. I assume now that perhaps the system is in some sort of state of preservation until needed.
I like the water wash down system on CV-16. Similar to the USN..I feel it does a much more through job than the Russian system.
Now the Russian system is quite different as demonstrated by the IN Vikramaditya during sea trails. They appear to use one single very powerful hydrant to wash over the flight deck.
