10 Revolutionary Stealth Technologies in Modern Naval Vessels
4. Thermal Signature Reduction

By means of creative heat management technologies, thermal stealth technology aims to reduce the infrared signature of a vessel. Modern ships use sophisticated cooling systems to control exhaust temperatures and spread heat around the ship, therefore preventing hot areas seen by infrared sensors. Whereas complex exhaust cooling systems mix hot engine gases with seawater before discharge, specialized materials and coatings reflect and dissipate heat. By constantly monitoring and adjusting thermal signatures, active temperature management technologies enable vessels to fit perfectly with the surrounding ocean temperature profile. Against thermal imaging systems and heat-seeking missiles specifically, this approach has shown especially success.
