Abstract
A countermeasure launcher system, for use by a submarine, reducing any detectable signature by preventing the escape of pressurized gas into seawater at the forward end of the system's launch tube upon launching a countermeasure. The pressurized gas that is used in launching the countermeasure is trapped within the launch tube by a unique arrangement of specific components. The pressurized gas is then permitted to slowly exit at a later time via a pressure relief valve in the launch tube's wall.
