Here's a great picture of the "beer can" RTWS receiver antenna.

Oh, that is right, got the RWR confused with IFF for some reason.

Thanks

IFF = "who are you?"
RWR = "who's asking?"
Wink

IFF = "who are you?"
RWR = "who's asking?"
HARM = conversation over!

Nice one Jim,
hehehe
had a good laugh over that one.

Now what do the older blocks use for IFF?

The non-ADF F-16 aircraft use the AN/APX-101(V) IFF System, built by Northrop-Grumman (Litton). This system uses the combined UHF/IFF antenna system (upper UHF/IFF is visible atop the forward rudder island, and the lower UHF/IFF antenna is either under the intake on early F-16 blocks, or between the ventrals, near the tailhook on newer aircraft), to receive the interrogation query, and transmit the coded reply accordingly. The IFF LRU also integrates altitude data from the CADC (central air data computer) to send Mode C altitude information.

The ADF F-16 uses the BAE Systems AN/APX-113(V), with an interrogator, transponder, and cryptographic computer module. The antenna arrays (aka the “Bird Slicers) are electronically scanning elements, to determine bearing information of the target aircraft relative to the host.

guys, 1 off-topic question. The IFF/AIFF system onboard the Russian platforms performs as per the above mentioned?

cheers,

FlightTestJim, isn't the AIFF on the CCIP birds the AN/APX-109(V)3 ??? Same as on the SuperDuper Hornets right? Does the -109 replace or compliment the -101?

habu2, you are correct. The AN/APX-113 is the newer version, going on the Block 60's. I don't know what the Hornets use (it's a Navy thing).
