So I can't see how that prob means they have to be scrapped.
Basically, they're kept in reserve and one person or another makes a comment one way or the other every few months. THis has been going on round about 10 yrs.
I doubt the to-ing and fro-ing will change any time soon.
Ultimately, scrapping doesn't bring any benefits. Nor are they at the top of the urgent list to return to the Fleet. Keeping them in reserve keeps all options open. And when the other 2 Kirovs are done, that is the time to consider refits.
