One has a range of 1600km (oficial not especulacion according to that blog) and the other has lesser range (300km exportacion/ 600km especulacion) while they look almost the same. Why not use 3M-14 as basis for an anti ship missile instead of the 3M-54-1?
I don't know for sure, but suspect the shorter range weapon is designed to hit ships and mobile targets, while the weapon with the longer range is a land attack weapon.
The shorter range weapon needs onboard radar to find and attack its target and might also carry chaff and flares and disposable jammers to enable it to penetrate the target ships defences... and may have a larger explosive payload.
Likely both missiles will have a domestic and export version with export models limited to 300kms or less.
Another factor could be detection range... enemy land threats that are fixed could be targetted from a wider range of places whereas finding enemy ships that can be clearly IDed as enemy and can be reached by a subsonic missile before it leaves the area means shorter range shots make more sense anyway.
At first I thought the 3m-14 was to be fired using 650mm torpedo tubes while 3M-54-1 can be fired with 533mm tubes. But other sites list both as can be fired using 533mm tubes with only 1 source listing the 3M-14 as 620mm and 3M-54-1 as 510mm, so I guess I'm wrong. Also I read somewhere that the 3m-54-1 uses the Kh-35's seeker, so probably the size is just for cost cutting? They're for low priority targets like transport ships? Cheap swarm missiles?
