R-73 performance in game
-
Does anyone know how accurately the R-73 is simulated in game? Here’s an ACMI track from some testing I was doing in dogfight mode. https://dl.dropboxusercontent.com/u/97148259/nuts%20r73%20shot.zip
As you can see, the missile flies off the rail, maintains ~250Kts, spikes up to 77 deg AOA, and peaks with a turn rate of 70 deg/sec. I know it’s a nasty little missile with thrust vectoring, but that just seems insane to me.

Rocket engine still ignited or not ?

Badly, like most missiles…. but I wouldnt trust ACMI on accurate flight parameters at the time scale of a missile flight

Especially considering TVC modeling and IRCCM.

Maybe some day the missles will get a make over?

let’s hope they will…

The actual information required probably isn’t easy to come by……

Yeah, the motor was still firing.

I trust it. When I fired the missile in game I did a double take because I thought the missile was flying through the air sideways. Sure enough Tacview said 70 deg aoa.

Agreed, but it comes down to modeling “in game” and not how it truly operates. One does not need to know exactly how the missile works, but rather how to mimic it’s known operational abilities. Seems we could even have an “in game” AESA if we knew more about what it can do, not how it does it. I know this seems contradictory but most of the weapons systems FBMS models is classified to some degree. The Dev team doesn’t model how these weapons work, rather they model known unclassified data on the those systems.

I dont think it sounds contradictory, I think it sounds circular.
Stuff is modeled based on how to make it mimic known operational abilities because the stuff is classified to an extent. That is the complaint here - just doing more of the same isnt going to make the complaint go away…?

Yep, and that isn’t going to happen. I think the values modeled are pretty good but needs some small improvements. Close to what known data we have. In fact, I don’t know if FBMS needs anymore data than it has with relations to missiles. Maybe better game operations with JDAMS and the like, but only to the point of perhaps being able to program the SAT targeting system and release procedures. Then again, that might be too sensitive to model as well. Just have to wait and see what FBMS does.
Since were on the subject of missiles, I would certainly hope to see the AIM 120D modeled. Been reading what I can on it. That missile’s got some legs!

Not really
The motor is the same than a C-7, so kinematically, it wont be a game changer for most aircraft. The main improvements for range will certainly be an optimized flight profile, and a significant increase of battery time. I would guess that for a 50 000 ft, M1.5 launch like the F-22 can do, the main range limiter is not the kinematics, but rather battery/self destruct time.
Bottom line : with the F-22 it will definitely have more range, but with an F-16, probably not a lot more.

This is not what is being reported. The 120D reached IOC in April. Tests (from what has been unclassified) has stated that the burn time is increased (approx. 8 seconds longer). Reaching greater than MACH 1.5 “initial” (dependent of aircraft launching speeds). Ranges vary but the WEZ is certainly farther and wider with a much narrower escape envelop (NEZ). Static numbers show a greater range of between 30% and over 50%. This missile has been quietly deployed to the Airforce/Navy and now Marine squadrons since July of this year. Still no solid info but I would not expect any. This missile IS IOC ready. Initial shots against drones (Q-4), shows it’s range to be above 90nm. I would only guess that it’s range (WEZ) would be somewhere between 50 and 80nm. Far greater range than the C-7 (WEZ estimated between 35 and 50nm).
So, YES, the slammer “D” has some serious legs! Not really you say? Really I say.

Where can I find these values? I need source. So far I thought that 50% greater NEZ/DLZ is valid only F-22 at very high alt just the usual marketing applied on any platfrom. It is impossible with same missile frame and engine reach 50% better range considering even just the most basic autopilot and terminal gudiance options…

Thankyou - I have the SARs and DOTE docs but they don’t list specifics so was wondering where the figures were coming from.
The Wiki page lists some figures and puts this as the ref http://docs.house.gov/meetings/AS/AS00/20130918/101291/HHRG-113-AS00-Wstate-GreenertUSNJ-20130918.pdf - States it is longer range but without figures. (other links are dead)
I do have this http://www.designation-systems.net/dusrm/m-120.html but it 2007 and links to nothing to state where they were getting the info from suppose it is possible Raytheon advertised a 50% improvement years back.
This is a better page but the info it links to has no figures http://www.bga-aeroweb.com/Defense/AMRAAM.html

It can if the time of flight is the (very) limiting factor for range…. but that mostly concerns high speed, high altitude shots. In low altitude shots, the D will indeed fall out of the sky at the same moment as the C-7
There is only so much you can do with basic rocket propulsion anyway. This is why ramjets have been considered for BVR for a long time now - the only problem is that it is really tricky to engineer in an AA missile.

…and your not going to find much info on it. But from what has been stated (take it for what it’s worth) this missile has some serious legs. Since most information used to model what FBMS is now, like WiKi and other open source info, the “D” info seems to be pretty consistent with what’s on the Wiki with other sights. It seems to have a longer range. Just how much is not known, but estimated to be greater (at least) than the C-7. The “D” is not the same as a “C-7”. It appears to be longer and a bit wider. See pics…
and….
Compared to a C-7….
Sorry for the large links. But you can see that the “D” is a bit longer and wider than the “C-7”. At least I can see it. Also, rumor has it that the dimensions for the “D” might be available at some point in the future. Most interesting to see this already being deployed on the viper in some of these pics.

Appreciate that - there is no information. Because of my background I totally ignore any figures without some kind of a credible source. This is actually a very good example of why Wiki is virtually irrelevant - anyone can edit the page and put any rubbish on there.
Almost imposible to tell from those photos - you want side on photos at the same angle and if you know the dimensions of the weapons bay or wingtip launchers that will give you a better idea.
