The British Type 31 plan is described as using thirty-two strike-length Mark 41 cells. Those cells accept larger weapons and can carry several smaller missiles in one cell where integration permits. Indonesia's design is described as having sixty-four Turkish MIDLAS cells for a smaller missile that cannot be packed in the same way. The apparent cell-count advantage therefore reflects different missile sizes and roles. A slightly heavier British gun fit is also mentioned, without a detailed comparison.

British and Indonesian Type 31 VLS choices
The British fit favours thirty-two larger strike-length cells, while Indonesia's sixty-four-cell layout favours a smaller air-defence missile.
