# "The missile flies to an intercept point specified prior to launch by its
|
||
|
|
# ground-based fire solution computer, which is embedded in the engagement
|
||
|
|
# control station. Target trajectory data can be updated during missile flyout
|
||
|
|
# by means of a radio frequency uplink/downlink. Shortly before arrival at the
|
||
|
|
# intercept point, the PAC-3 Missile's on board Ka band seeker acquires the
|
||
|
|
# target, selects the optimal aim point and terminal guidance is initiated.
|
||
|
|
# The ACMs, which are small, short duration solid propellant rocket motors
|
||
|
|
# located in the missile forebody, fire explosively to refine the missile's
|
||
|
|
# course to assure body-to-body impact.
