This is quite rare. I was a sailor on De Ruyter. In 1989 the ship was overhauled and was then fitted with a Goalkeeper on the hangar and SatCom antennas on the bridge. On this picture you can see the Goalkeeper but not the SatCom antennas on the bridge. They should be quite visible

Intersting perspective. These 2 ships, TROMP & DE RUYTER, were dubbed "Kojak" because of their radar dome sitting on top of the bridge.
