A weapon system having a breechblock, wherein the breechblock can be mechanically connected to a drive of the weapon system. The weapon system comprises means which are designed in such a way that a mechanical separation occurs between the breechblock and the breechblock drive with the recoil of the recoiling masses of the weapon system. With the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is re-formed.
