MK 13 Launcher

Rougher seas are automatically compensated by gyros and the launcher itself is changing his elevation accordingly.

The SM-1 is alinging itself after launch to follow a guidance radar beam to the target. The missile control radar is actually switching to CWI (continuous wave illumination) with a random frequency. This is to make sure the missle is following the right path and never loses contact with the radar if more than one missle is in the air and more than one ship is controlling them. Loosing contact will initiate a selfdestruct sequence. The chosen frequency is sent to the missle during the launch process using a plug right next to the exaust. This is (incl. chosing the frequency) also one of the reasons, why the lauch takes app. 2s from pressing the button `til "Bird away". The missle is alinging itself "on the" CWI-beam by reading the reflected signal from the target in the nose cone and by receiving the radarsignal from the radar itself in one of the side (longer) fins. The high start point ensures proper alingment to "ride the beam" to the target. It ensures, that the missle actually finds the radar beam it is suppose to follow.

You can download these info on the internet. e.g. try "radar guided SM-1 CWI"

I think to simulate that in DW is actually not necessary, since the homing technique is not simulated as such.
