Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission.
In addition to greater firepower, VLS is much more damage tolerant and reliable than the previous systems and has a lower radar cross-section (RCS).
When installed on an SSN (nuclear-powered attack submarine), a VLS allows a greater number and variety of weapons to be deployed, compared with using only torpedo tubes.
This potentially makes a hot-launch system relatively light, small, and economical to develop and produce, particularly when designed around smaller missiles.
For this reason, Russian VLSs are often designed with a slant so that a malfunctioning missile will land in the water instead of on the ship's deck.
Soft-launch provides the missile with a reduce interception rate allowing for shorter ranged engagements, reduces the IR signature of the ship and the obscurant of visibility by rendering the ship in efflux for several minutes; and most notably, the lack of hot efflux and reduced stress on the ship's structure allows for a much greater choice of launch systems, such as the lighter Mushroom Farm launcher whilst also still enabling installation into the heavier Mark 41 in a quad-pack or dual-packed configuration (4 or 2 missiles per cell) for a costly, but more space efficient option.
BAE Systems has filed patents relating to the use of Vertical Launch missiles from modified passenger aircraft.
Note: The above table does not include NATO navies which do not possess vertical launching systems, namely Albania, Croatia, Estonia, Iceland, Latvia, Lithuania, North Macedonia, Poland, Romania and Slovenia.
