It's claimed to have an operational range of 3000km.
Kh-55 has a similar range, but lower speed (sea-skimming, though).
Then there is the Kh-32 with operational range stated as 600-1000km.
And then there are plenty of missiles of ranges from 300-1000km.
Also, China is actively developing similar systems.
I suppose it's classified at what ranges these systems would be able hit targets such as carriers. But if they're able to at all, it would be at rangers much beyond what you can defend against with aim120/aim160 missiles.
RIM 161/SM3 would provide some protection, but they are probably not very accurate at the extreme ranges, especially if targetting supersonic attackers.
Which means that interceptors may be the best option. Against large groups of enemies, the speed of the interceptor is still relevant, and there are certainly some in the Navy that worries about the loss of the F14, in particular in the Pacific.
For now, I suppose it makes sense to have some F22's and F15's in the general area where such conflicts could take place.
Well, according to Wikipedia, it's nicknamed "Carrier Killer". Also, if it's specified speed is correct, it would travel at several km per second, and reach the carrier in 2-3 minutes if fired from 1000km away.
If it has any kind of ability to home in on the ship based on radar, sattelite or similar, it shouldn't matter much if it's fired from 200km or 2000km. And even less if it carries a nuke. Even at 40kn, a ship doesn't go THAT far in 3 minutes.
Of course, if it's not performing per specification, it wouldn't be the first time for a Russian weapon system. So it makes sense to take the claims with a grain of salt.
The main point, though, is that in some places, it's hard to protect important assets from all angles against enemies that are a lot faster. This may not be all that important in Eastern Europe. It might be more important in the Arctic, Middle Eastern or Pacific theatres, though.
At the very least, speed allows each plane to patrol a larger area in relatively remote places.
