In 23 years of active servise, the Kuznetsov had deployed on active operations nine time. Five to the Mediterranean, three to the Atlantic, and one to the Barents. It is interesting to note that in her first fifteen years she was only officially deployed three times. Since that time, in the last eight years, she has been officially deployed six times...twice as many in about half the time, so four times the frequency. The Russians have really stepped her up in the last eight years compared to the first fifteen.
In that same time, she has been (including the present one) laid up for repairs and refit five times.
When deployed, she normally goes out with 12-14 SU-33s, a couple of SU-25s and 10 or more ASW/SAR helicopters. The Russians have a total of 19 SU-33s, but intend to replace the SU-33s with Mig-29Ks on the Kuznetsov after her current major refit.
