So you don't get shot down by your own air defense
- monetus 3y ago- as demonstrated by more than one aircraft since the war in Ukraine began.
- next_xibalba 3y agoWhy would it need to be interoperable then? Presumably it tells adversaries that you’re friend OR foe though. The friend bit is obvious. The foe… still not seeing the logic.
- aerostable_slug 3y agoThere's a difference between civilian transponders which generally squawk all the time and military IFF, which typically only responds to a coded challenge (called an IFF interrogation). If a military IFF doesn't receive a valid interrogation, it remains silent. It is Very Bad if an enemy can either spoof a valid "friend" IFF response or cause IFFs to respond and give up one's position. The latter was done with great effect in both WW2 and the Vietnam War.
- gpderetta 3y ago> spoof a valid "friend" IFF Tricking an enemy plane to respond seems "fair", but would a plane disguising itself as friendly count as perfidy?
- simne 3y agoThat's easy. On many civilian planes, beacon turned on automatically, but on military must be turned on intentionally. Because of this, extremely typical, when you see military plane, but have not got alarm about it's approach - just pilot forgot to turn on beacon. FoF system is totally another measure, in real dogfight they do not consider it much, it is mostly like additional spare fuse, may save your life in some case. Rumors said, pilots of U-2 was pray, to avoid cases, where need to use these radio tricks.
