The '''Sylver''' ('''SY'''stème de '''L'''ancement '''VER'''tical) is a [[vertical launching system]] (VLS) designed by [[DCNS (company)|DCNS]] and introduced in 2001.<ref>{{cite web |title=Sylver |url=https://www.deagel.com/Cannons%20&%20Gear/Sylver/a001421 |website=Deagel.com |publisher=Deagel |access-date=9 January 2022}}</ref>

==Specifications==
[[File:Sylver Launching System - Types of Missiles.gif|thumb|Comparison graphics]]
The basic unit of Sylver VLS is an eight-cell module fitted with two rows of 56&nbsp;cm. missile cells surrounding the uptake for exhaust gas, and the specifications for different models are as follows:

|-
| '''A-35''' || 3.5 metre || 2.3 metre || 3.5 metre || 7 ton

| '''A-43''' || 4.3 metre || 2.3 metre || 4.3 metre || 7.5 ton

</div>

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 missile]]s, the A-50 for the long-range [[PAAMS]] air defense system, and the A-70 launcher for longer missiles such as the [[MdCN (missile)|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 {{convert|4.3|m|ftin}} long whilst the A-70 can accommodate missiles up to {{convert|7|m|ftin}} long.

The launchers come in eight-cell modules, except A-35 available in four-cell modules, with each eight-cell module occupying {{convert|6|m2|spell=in}} of deck space. Inner size cell is {{convert|60|cm}} long and {{cvt|56|cm}} wide, and each cell has its own exhaust vent. [[Crotale missile|Crotale NG (VT1)]] missiles can be quad-packed in one cell.

The primary application of the launcher has been the [[Aster (missile family)|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 (missile)|MdCN]], the missile gives the French Navy a [[land-attack missile|land-attack]] capability in the mould of the [[United States|U.S.]] [[Tomahawk (missile family)|Tomahawk]].
