+#    "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.
