These things detect incoming missiles..Quote from: "Odinson"
Using Phalanx to take down incoming missiles travelling over 3000km per hour for a naval ship is kind of risky and only used as the last resort. Million watt powered infrared lasers have proven far better range, accuracy, speed and stability. And not to mention terminal high altitude area defence deployed on land and installed on ships will be the most critical to detect missiles launched from anywhere within China or if not half of the Asia mainland as an early warning system.
