AN/SPS-2
AN/SPS-2 was a long-range 3D L-Band search radar using a stacked beam antenna with seven beams in vertical plane. Unfortunately it was too big for anything but large cruisers. Due to its huge size and weight it was only installed on two ships, USS Northampton (CLC-1) and USS Little Rock (CLG-4). The antenna alone weighed 55 000 pounds (23.6 metric tons), the whole radar system weighed 100 000 pounds (about 44 metric tons).
