According to https://en.m.wikipedia.org/wiki/Typhoon-class_submarine of the 6 built, 3 are scrapped, 2 retired, and 1 in service (though later on that same page it says the last SLBM of the type used was decommissioned in 2012).

Based on the pictures, it definitely doesn't look like in service. Also, seems quite strange if they'd let civilians (?) run around and take pictures of a strategic weapon system in active use..
