"        In the vastness of the open ocean, anti-ship missiles must use radar to find their targets. A typical anti-ship missile has an active radar seeker that sweeps the broad, flat expanse of ocean before it. Once it catches a whiff of something on radar, it adjusts course and barrels down on a target until it finally smashes into it.  To avoid this, during World War II, defenders on both sides would release thousands of tiny strips of aluminum foil into the air. Enemy radars would pick up and interpret these strips as a solid form\u2014at least until they dissipated with the wind. This became known as chaff, and has been an effective way of confusing radar ever since.  More than 70 years later and chaff is still being used. In the video above the German frigate Karlsruhe fires off its Super Rapid Bloom Offboard Countermeasures Chaff and Decoy System\u2014mercifully shortened to SRBOC. SRBOC is a system of launcher tubes on both the port and starboard, each tube set at a slightly different angle so at least one is covering every position of the ship. Once fired, they create a new fake &amp;quot;ship&amp;quot; for the incoming missile, confusing it, and hopefully improving the defender&amp;#039;s odds of survival. SRBOC uses aluminum-coated glass fibers that linger in the air longer instead of aluminum strips.  All modern navies have a countermeasures system similar to SRBOC. Some simply launch chaff, but the Karlsruhe appears to also have the TORCH infrared decoy system for fooling infra-red guided missiles hunting for its smokestack.  Here&amp;#039;s a video of the US Navy destroyer USS McCampbell firing SRBOC in daytime. It&amp;#039;s not as impressive, but does show the mortar-like launcher chugging away.
