Undersea Warfare

L3Harris provides leading-edge C4ISR sustainment and undersea solutions in the areas of sensors, power and seabed systems. Its undersea warfare systems include integrated, superior, multi-domain sensor capabilities, acoustic/undersea systems & sensors, seabed systems, unmanned underwater vehicles and imaging systems on naval submarine programs.

L3Harris is the world’s largest submarine imaging system provider with imaging masts on all classes of U.S. Navy submarines, delivering precise, high-resolution optics, and integrated sensor packages. Outside the U.S., L3Harris has submarine imaging systems in-service on the widest variety of submarine classes – from German-manufactured U209s to Russian-manufactured “Kilo-Class,” Netherlands Walrus, Spain S-80 and even the legacy Romeo-Class submarines in service with the Egyptian Navy.

L3Harris continues to outfit leading navies with proven fixed and mobile acoustic surveillance technology to keep oceans safe, delivering real-time situational awareness and targeting.
