Why Russia’s R-77 Missile Could Give the Air Force Some Real Trouble
Technologically, the R-77 is an active-radar homing missile, meaning that the seeker itself has a small radar that sends out radar pulses to detect the target and then uses that information to home in on the target.
Here s What You Need to Remember: The upcoming R-77M variant for use on the Su-57 is exciting, with the possible AESA seeker and return to a traditional fin layout. There also is the version that’s powered by a ramjet, the R-77PD. This version was seen at MAKS 2001; however, it has not been seen since, and development is believed to have stalled or been canceled.
