Pyrotechnic signals serve as a means of recognition or signaling between submarines in submersion and aircraft or surface vessels.
Our submarine-launched solutions are used by submarines around the world to transmit, via a brief, pre-set code, information on submarine maneuvering or a distress signal.
Highly visible red, green or yellow star signals transmit a brief, pre-set code (e.g.: red = emergency surfacing, green = torpedo launching simulation, etc.).
Smoke & Flares: Flame and smoke (white color) for day and night use
to indicate its current position or to transmit a brief, pre-set code to naval forces and search and rescue teams.
Colored Smoke -daytime use
to transmit a brief, pre-set code to naval forces and search and rescue teams (e.g.: torpedo launching simulation, etc.)
This underwater countermeasure is to decoy active sonars (surface ships, helicopters, submarines and torpedoes) by generating false echoes.
