SUBMARINE LAUNCHED ROCKET SIGNAL RED / GREEN

Description

The Submarine Launched Rocket Signal (Red/Green) can surface from depths of 500m+, with specialist models capable of depths in excess of 750m. On the surface, a rocket will be ejected from the unit to travel 170m into the air. At the top of the trajectory the rocket will ignite into the designated Red/Green flare and a parachute will be deployed to provide a signal of 40 seconds. To extend the time of display a second rocket will be ejected 10 seconds after the first providing a total of 50 seconds of display.

Application

The Submarine Launched Rocket Signal, when combined with a Red rocket is required under STANAG 1298 as an optical means of alerting surface crews of a submarine in distress. In accordance with NATO Multinational Tactical Signal and Manoeuvring, the submarine will surface immediately if possible. All ships are to clear the localised area and stand by to render assistance.

The Submarine Launched Rocket Signal, when combined with a Green rocket, is used under NATO Multinational Tactical Signal and Manoeuvring, for indicating a submarine attack or an exercise signal to indicate that torpedoes have been fired.
