Patrol special vessel FFX B-II

The Standard for State of the art Korean Frigates To maximize survivability, the ship is applied with LPI (Low Probability of Intercept) designs, such as RCS (Radar Cross Section), IR (Infrared), URN (Underwater Radiation Noise), and EM (Electromagnetic). These were utilized as the basis for the stealth design technology of the successor, FFX B-III. Equipped with the Latest Korean Weapons and Sensors Compared to FFX Batch-I, FFX Batch-II features additions such as KVLS (Korea Vertical Launch System), IRST (Infra-Red Search and Track), and TAS (Towed Array Sonar), resulting in enhanced combat performance that surpasses that of the KDX-I Destroyer. This is attributable to the integration of various Korean weapons and sensors. Anti-Submarine Warfare-Specialized Frigate FFX B-II is the first ship in the Korean Navy to feature a hybrid (electric/mechanical) propulsion system, significantly reducing underwater radiated noise. The ship is also equipped with TAS (towed array sonar), which was previously only installed in destroyers before, thereby maximizing its operational capability in anti-submarine warfare.
