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.
