Naval Shtil missile variants

…
The missile at the left must be 9M38 while the right is 9M317.

dunno though if naval version have its own designation.

Thanks. As per Global Security:

The 9M317 missile, compared to the 9M38M1 missile incorporated into the Buk-M1 system, has an extended engagement envelope of up to 45 km in slant range and up to 25 km in altitude and horizontal range, as well as a broader range of targets which can be engaged. Range of targets with RCS = 5 m² is 40 km. The different appearance from the 9M38M1 includes significantly shorter length of the wing chord. It provides for the use of inertial-corrected control system with semi-active radar seeker 9B-1103M-guided navigation on a proportionate basis.

hmm should be this

The missile at the left must be 9M38 while the right is 9M317.
