![]() ![]() In third place: the Atago Class Destroyer. If the electronic information systems are assumed to be reasonably constant between all four, then firepower can server as the tie-breaker. However, those technical details are classified. One answer is that it’s likely that each vessel has uniquely modified components of the Aegis Combat System. How should the top four warships be ranked given that they share crucial combat system capabilities? ![]() The King Sejong the Great Class Destroyer features the SLQ-200K Sonata EW suite, which uses a wideband signal and digital receiver with analysis and identification capabilities to detect hostile activity and omni-directional jamming technology to counter it. The Aegis-integrated EW system is designed to both detect and counter hostile radar or guided missile signals. Each radiating element can be moved to certain angles by electronically-controlled ferrite or diode phase shifters. These generate power for the beam-radiating elements. This transmitter is made up of high-power microwave tubes, which are tubular vacuums that create and amplify high frequency signals within the range of 300 MHz to 300GHz. It is a passive phased array radar, which means it is comprised of a centralized transmitter or stationary antenna. The AN/SPY-1 radar is a critical technology in its own right. This picture can then be evaluated by command stations and the integrated fire control system of the MK 41 VLS, which is capable of launching anti-surface and anti-ballistic SM-3 and SM-6 missiles. Both the radar system and helicopter platform collect sensory and tactical data and work together with the EW technology’s intercept capabilities to create a comprehensive battlespace picture. For example, as part of the Aegis system, the BMD system is networked with the AN/SPY-1 radar and a MH60R helicopter. ![]()
