SURFACE-LAUNCHED MISSILES

destroyers will be installed on new Arleigh Burke- class destroyers (fig. 1-5). SURFACE-LAUNCHED MISSILES The mission of surface-launched missiles, shown in figures 1-6 and 1-7, is to engage and intercept aircraft, antiship missiles, and surface ships. Standard-1 (SM-1) and Standard-2 (SM-2), medium-range (MR), and extended-range (ER) missiles have a cylindrical airframe. The airframe tapers into a radome, four fixed dorsal fins, and four independently movable steering control surfaces. Standard-1 (RIM-66) is a medium-range (MR), surface-launched missile employing passive or semiactive homing. It is propelled by an integral dual-thrust rocket motor, SM-1 MR is installed on FFG-, DDG-, CG-, and CGN-class ships equipped with Aegis and a Tartar combat system. Standard- 2MR incorporates midcourse guidance, which allows programming of the missile for radar search only. The missile is redirected in midflight and then again during the terminal homing phase. SM-2 MR is installed on the DDG- and CGN-type ships and on Aegis CG-class ships. Standard-1 (RIM-67) is an extended-range (ER), surface-launched missile employing passive/ semiactive homing or midcourse command guidance. It is propelled by a detachable rocket booster and an integral sustainer rocket motor. SM-1 ER is installed on CGN-, CG-, and DDG-37- class ships equipped with Terrier combat systems. Standard-2 ER incorporates the same midcourse guidance as the MR version. Figure 1-5.—USS Arleigh A. Burke (DDG-51). 1-14
