Also known as Northrop Grumman AN/APG-77, Northrop Grumman APG-77, APG-77

The AN/APG-77 is a multifunction X-band, low probability of intercept radar (LPIR) installed aboard the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.

The AN/APG-77 is a multifunction X-band, low probability of intercept radar (LPIR) installed aboard the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.

It is a solid-state, Active Electronically Scanned Array (AESA) radar whose design is based on the AN/APG-66/68/80(V) family of fire control radars. Composed of 1,956 transmit/receive modules (TRM), each about the size of a gum stick, it can perform a near-instantaneous beam steering (in the order of tens of nanoseconds).
