Before we go into details lets first get the terminology right.
A Vertical Launch System consists of
modules with a number of
cells These
modules can be in
cells of 8,16,32 or 64 . Or it can be any number of cells that fits in to the hull of the ship if it is a naval platform using it.
These cells are filled with
canisters that contain
missiles. These canisters can be packed with
single, dual or
quad missiles.
Cells of MK41 VLS
A
canister of MK41 with quad packed ESSM.
A
module of a MK41 VLS.
A quad packed MK41 VLS system with ESSM
These missiles when fired give out tremendous amount of heat, and the flames from the exhaust gasses must be ducted out in a safe manner. Every cell group has an individual exhaust duct system that releases these flames and gasses.
Now, according to the size of our VLS MILDAS and the size of the missiles that will be accommodated within the canisters that will fit in to the modules and cells, Roketsan will try to fit as many of these missiles as possible in to each canister, as per the directives of the Naval Command.
Also as per the post shared above by our
@UkroTurk , that contains Mr I Sunnetci’s comments; Hisar D RF missile will have quad packability . But using in MILDAS , the ESSM may not be possible as there seems to be a compatibility issue between MILDAS and ESSM .
It is imperative for our MILDAS to accommodate quad packability of Siper too. This will help a lot in ships like Istanbul Class where space and number of usable cells are sparse .
