The "K-VLS" is comparable in size and role to the strike-length Mk 41 VLS. It comes in 8-cell modules sized at 3.165 m × 2.076 m × 7.7 m.
The "K-VLS Compact" is specialized for the K-SAAM surface-to-air missile. It comes in modules of 4 cells, sized at 2.9 m × 2.6 m × 4.9 m (length-width-height). Its role can be compared to the Mk 48/56 VLS for RIM-162 ESSM.
Dosan Ahn Changho-class submarines use a K-VLS that has a module size different from either version. Presumably this is a distinct variant comparable in role to the US Mk 45.
A newer version called KVLS-II was unveiled in 2021. It comes in modules of 4 cells, sized at 3.0 m × 2.4 m × 9.8 m (L-W-H). An upsized system with increased exhaust handling capacity, its role is comparable to the US Mk 57 VLS.[4]
