The ship's main dimensions are named in the types itself
SIGMA 9113 means length of 90.71m, beam of 13.02m and draft of 3.60m. Displacement 1,700t
SIGMA 9813 means 97.91m in length by 13.02m wide. Draught 3,6m. Displacement 1950 tons.
SIGMA 10513 means 105.11 meters in length by 13.02 meters wide. Draught 3.6m. Displacement 2185 tons
SIGMA 10514 means 105.11 meters in length by 14.02m wide. Draught 3,7m. Displacement 2365 tons
Deck height is 2.75m. Depth 2-deck is 6m. I see a max. of 3,5 decks depth available for weapoms accommodation: i.e. about 9.6m, plus a bit because a) depth 3-deck will be larger than 3x 2,75 and b) some protrusion above deck. Which might just fit the Russian Universal VLS
