As long as the first target “dot” stays visible on the 4 degree TWS scan, Phoenix will guide on it using data link, but if it only for one second disappears, datalink is broken and missile is on inertial.
This is why there are many people advocating for fixing F-14s TWS jumping lock. It jumpes once and datalink is severed and cannot be fixed. Interesting info is that the new Fox 3s had datalink reconnect, but I’m not sure if it worked even.
just noticed today the the Mirage-2000D has all large calibre CM’s aren’t half of them supposed to be regular? considering it shares the same countermeasure system as the 5F on the belly?
The problem is that the AWG-9 (even though its mechanical and 70s tech) is actually pretty smart. It will automatically move its radar dish to keep the thing you are TWS guiding the missile to, to keep the Aim-54 on track.
Gaijin cant model yet the how TWS guides multiple targets and keeps them all in TWS mode even though those multiple targets could be at different altitudes.
How is that possible without difficulties? The radar would need to have electronic scanning to provide sufficient quality track at different altitudes. The AWG-9 already had trouble maintaining TWS lock on maneuvering targets. The radar simply just doesn’t scan fast enough to sufficiently guide against multiple maneuvering targets at different altitudes let alone just at one altitude.
The AWG-9 struggled heavily to provide TWS track against maneuvering targets irl, or against multiple targets spread far out. One single defensive target is hard enough without SARH mode hard lock.
problem is, if you are trying to guide 3 phoenixes to 3 targets, and those 3 targets aren’t “aligned” the dish will necessarily lose the track on one of the three. Scanning pattern is still a good old “left-right-left-right and repeat”.
