What is the primary surface search and navigation radar, with limited air search capabilities for CVNs?

The AN/SPS-67(V)1 is primarily designed for surface search and navigation purposes, making it the main radar system used on aircraft carriers (CVNs) for this function. One of its strengths lies in its ability to detect surface targets over a wide range, providing critical situational awareness for navigation and maritime operations. Although it has some capacity for limited air search, its primary focus remains on surface tracking, which aligns with the operational needs of a carrier navigating through potentially congested seas and ensuring the safety of other vessels nearby.

The radar's capabilities are vital for mission planning and execution, as it assists with identifying nearby ships, obstacles, and other relevant surface contacts. The specific configuration and features of the AN/SPS-67(V)1 enhance its effectiveness for carrier operations, where maintaining awareness of the surrounding maritime environment is essential.

Other radar systems listed, such as the AN/SPS-46(V)1, AN/SPS-55, and AN/SPN-46(V)1, serve different roles. For example, the AN/SPS-46 is more focused on air search capabilities and is not primarily developed for surface orientation, while the AN/SPN-46 is designed more for precision approach and landing assistance rather than extensive surface
