This photo was taken from part way up the south end of the "ZEUS" berm shown in the first photo. From there, it is looking east, southeast toward the Zeus Acquisition Radar (ZAR) facility. The facility is approximately 1 mile away. The large white dome was the ZAR Receiver Antenna. At this time, it is not known what the building to the right of the large dome was used for. It most likley was a maintenance facility of some kind. It wasn't a system building. The first building to the left of the dome with the triangle shaped structure on the top was the Receiver building. The triangle structure was not a part of the original Zeus building (more about it later). To the left of the Receiver building is the Transmitter building. The part you can see is the transmitter antenna. It was a triangle shaped antenna which transmitted in three directions as it rotated. The building was built below ground and there was a low berm around it with a tunnel for personnel use to enter/exit the building. The antenna was about all that could be seen from ground level.

     After the Zeus program ended, the triangle structure shown on the the receiver building was added. The structure was the array structure for for the HAPDAR phased array radar with its single array on the left side of the structure, pointing north (see next two photos). The phased array radar transmitter and receiver were located in the building. The large dome remained there for many years. A contract was let to remove the dome in the early 1970s. While removal was in progress, the dome caught fire and was completely distroyed. The transmitter antenna was removed from the building and it has been used by various organizations for workspace and storage. For many years, the receiver building has been occupied by the Patriot Test Operations team, the group that conducts government testing of the Patriot System.
