909 SEADART FIRINGS

This picture shows a Type 42 destroyer firing her Seadart Missile, but the real reason for the picture is to show you the forward and after 909 radar housed in their radomes.  The after 909 is obvious just abaft the mainmast but the forward 909 more or less on the bridge top is beginning to be masked by smoke from the launched missile.
