AN/SPS-67 is a two-dimensional pulsed radar set primarily designed for surface search and navigation, and limited air search capability. It can also detect antiship-missiles (ASM) and low-flying aircraft. The AN/SPS-67 is a successor to the AN/SPS-10.

The AN/SPS-67(V)3 antenna consists of an L-band IFF- monopulse array antenna integrated atop a C-band feed horn array antenna using horizontal linear polarisation. Its nominal elevations beamwidth is 28 degrees.

Below-decks, AN/SPS-67 consists of a transceiver, a video processor, radar control unit, an antenna controller and an antenna safety switch, all of which are housed in five cabinets. System performance is improved via the addition of a very narrow pulse mode (0.1 µs) for better navigation and improved resolution of small targets at short ranges. Long and medium pulse (1 and 0.25 µs) modes are used in open sea for detection of long- and medium-range targets.
