The basic unit of Sylver VLS is an eight-cell module fitted with two rows of 56 cm missile cells surrounding the uptake for exhaust gas, and the specifications for different models are as follows: The launcher comes in several variants, each distinguished by their height. A-35 and A-43 were developed for launching short range
surface-to-air missiles, the A-50 for the long-range
PAAMS air defense system, and the A-70 launcher for longer missiles such as the
MdCN naval land attack
cruise missile. The numbers refer to the approximate length of the missile which can be accommodated, in decimetres, i.e. the A-43 can hold missiles which are up to long whilst the A-70 can accommodate missiles up to long. The launchers come in eight-cell modules, except A-35 available in four-cell modules, with each eight-cell module occupying of deck space. Inner size cell is long and wide, and each cell has its own exhaust vent.
Crotale NG (VT1) missiles can be quad-packed in one cell. The primary application of the launcher has been the
Aster. The Sylver, together with the Aster, is the primary component of the PAAMS naval
anti-air warfare system. Using PAAMS, up to eight missiles can be launched in 10 seconds.
France has developed a sea-based deep strike cruise missile capable of being launched from the Sylver. Called the
MdCN, the missile gives the French Navy a
land-attack capability in the mould of the
U.S. Tomahawk. ==Operators==
