5. Electronic Emissions Control

Modern navy stealth technology depends critically on advanced electronic emissions control technologies. From radar, communications, and electronic warfare systems to all electromagnetic emissions from a vessel, these systems control Sophisticated frequency-hopping methods and signal processing help low-probability-of-intercept (LPI) radar devices remain unidentified while preserving surveillance capability. All onboard electronic emissions are coordinated by integrated electromagnetic signature management systems, therefore enabling vessels to run efficiently and with minimum electronic visibility. This method consists on selective emissions control depending on tactical conditions and adaptive power management.
6. Wake Reduction Technology

To lessen the obvious surface disturbance caused by ships, modern naval architects have developed creative wake reducing technologies. Among these technologies are active wake control systems, hull forms that lower wave-making resistance, and sophisticated propeller designs. While computer-operated trim systems constantly maximize the vessel’s attitude in the water, specialized bow and stern configurations cooperate to reduce the development of characteristic Kelvin wake patterns. Some sophisticated systems even use air injection technology to change water flow patterns around the hull, therefore lowering apparent wake effects. Through direct inspection or satellite images, these combined technologies make ships noticeably more difficult to find.
