I don't know if the Hornet has ALE-50, but to be honest I wouldn't expect it in DCS if it does, after all we'd need on board ECM to be operable first before off board systems would become practical.

One can dream though.

It seems the USN still carries AIM-7...at least on exercise

Close up of the fuel pray bars and the flame holder on what look like to me the F404-GE

The Navy still uses the AIM-7P in training and on combat missions. They have been seen being carried on aircraft over Syria.

I have seen Air refueling videos where they carry them, but when I mention it I was told otherwise

We trained with them and we carried them when required. They are still a viable weapon for the Navy even if the Air Force no longer uses them.

Talking about exhaust, I have seen many Legacy Hornets with different turkey feathers and variable nozzles including with ceramic coating. I find it beautiful.

F404-402 seems to be a very fuel efficient engine when using afterburner. Was taking a look at the fuel flow and its not anywhere near to the F100 of the Eagle.

Also conciser that the F404 is a lot smaller. GE also uses a different fuel delivery system. PW uses the fuel rings while the GE use spray bars. If this is anything like the F110-GE, the long bars are called core fuel bars, short ones are the fan fuel bars. At 5:30 position, closes the the guys, should be the EGT probe and at around 4:30, inside the flame holder, you can see the single igniter for the AB. Also note how the flame holder is in sections for ease of maintenance. PW engine (220, 229) have this area coated with ceramics while GE are normally not. Apparently GE figure out how to have enough bypass air flow to prevent exhaust tube melt through on normal conditions. This is all speculations of course, when I worked this engine the exhaust was part of the aircraft and was a bit different. Hopefully, one of you guys can tell me how close or far I am form the actual operations on this exhaust.

They are different engines, I am not sure if we can compare them directly, correct me if I am wrong but the F-404-GE-402 is meant to have a higher fuel efficiency, while the F100-PW-220 is more powerful and bigger as you said. But I don't really see much relation between fuel flow and the flame holder, the way fuel is being sprayed into the jet pipe. (I am not saying there is none but usually fuel flow is related to pressure ratio).

About the ceramic coating, for example the GEnx uses a lot CMC in the hot section of the engine, since ceramic offers a better thermal protection and also slows down the heat transition from the coating to the alloy of the turbine nozzle, turbine blade or whatever it might be. It also has 2/3s the weight of the best alloys used in the hot section of the engine, and since CMC is able to handle higher temperatures, the engine needs less cooling air, therefore the engine is operating at higher temps, and cooling air may be used for combustion process. This makes the engine more efficient.

And lets not forget the fact that Hornet uses FADEC which tends to find the best AFR (air fuel mixture) for the engine. While the F100-PW-220 isn't, that might be wrong tho.

F404-402 also has some fuel flow improvements compared to its predecessor.

Anyway.. Wrote too much today.. They are different aircraft, different purposes, with different engines!

I know, your right. Very different engine

I do not know.

Between the flame holder and they way fuel sprays, no, no correlation. On those I just wanted to talk about the exhaust system in general. In terms of the fuel flow, AFAIK, the size of the engine and the different system help on the fuel consumption. In my opinion the GE version is more efficient (completely base on opinion and no data)

They all use "FADEC", even the F-100-PW-100 has a rudimentary one.

Anyway, how many modes of operations does the F404 have? If the "FADEC" (I don't know the actual name on this engine, is it a Digital Engine Control, DEC) fails or detects any faults, does it revert to a analog mode? Does this engine have a Main Engine Control (MEC) as a back up for the "FADEC"?
