R-73 missile?

[Zius]

I think the addition of the R-73 missile to the module would be a great update and would make dogfighting F-15 level aircraft much more feasible.

 

But I am not sure how realistic it is. Are there MiG-21bis (not Lancer or Bison) aircraft fitted with the R-73?

Requires the upgrade after Bis. Like Mig-21-93/Bison/LanceR

 

So... Sadly No.

[Zius]

Thanks, but why? The missile has it's own seeker and should be not that difficult to integrate? Or is there some fundamental difference with the R-60 in that respect?

[Frederf]

Difficulty is irrelevant. History is written.

Well, R-73 has the capability for the HMS and as it has better new seeker, and so on likely requires new protocol to deliver the data back to FCS. Of course it depends how simple a IR seekers are in the soviet missiles? Like what they really need to output to FCS than "I see something/nothing, I have a signature, I GO" when considering simple boresight targeting like with R-60 or any other.

 

As Su-25T doesn't implement HMS but can carry R-73, it is interesting question that is the R-73 just left away from Mig-21Bis as it wasn't ready yet for years.

 

R-73 is 1984 and Mig-21Bis is from 1975 so 9 years difference between these two. So if the launcher for R-73 is incompatible with the Mig-21Bis then that might be the case?

 

So, here we are again having a simple conflict with the module developments.

 

1. We are flying a aircraft that is serviced 1975 as 1975-1980 era, yet the cockpit textures are from 2015 or so from museum.
   
2. We are flying a 1975 aircraft at 2017 with a weapons available 2017, instead 1975
   
3. We are flying a 1975 aircraft as 1975 but we have the enemies from the future.
   

 

The history is written, we can't change that. But if a Mig-21Bis could use as is a R-73 without modifications today, then we should have a change to weaponize it with R-73 when we are flying a missions or against a more modern enemies, as it was a replacement for a R-60.

As well those who have Mig-21 in service, likely has been looking the update to their armament so why not update to more newer Mig-21 with R-73 HMS instead just adding R-73 (if possible) when once doing so?

 

But likely the wiring and launchers are not compatible with Bis so no change, as we are flying a museum piece.

Well, I don't think this is some difficult upgrade, and even in reality some vanilla Bises flyes with R-73 e.g. cuban aircraft:

 

APU-72 launcher is clearly visible under wing.

 

But honestly I have no idea is this some local initiative or original Russian concept. Anyway already R-60 is kind of simple addition (upgrade) to weapon system, that's why R-60 light panel looks so "pasted". Originally Bis didn't had those missiles, and aircrafts sold abroad SU got them only from year 1984 ( even Warsaw Pact machines ).

[Sarraceno]

I don't see why not, if vanilla BISes carry them, even if its only some regional variation... Still better than Kh66 or the gunpods (gunpods were discarded after first trials)

[Zius]

Thanks for the info guys!

 

HMS would be great, but I'd imagine a bit more complex to integrate in real life than "only" another missile. But maybe I'm wrong...

[lemoen]

Its not only the launcher, you also need the avionics box inside the plane to be compatible with the missile. The one inside the BIS may or may not be compatible.

[BadHabit]

The avionics suite would be for HMS use or missile uncage. If a Su-25T can carry them using Bore sight mode, why a 21Bis wouldn't?

[red_coreSix]

A MiG-21 can also be seen firing an R-73 in this video around 2:20.

Don't know what version this is or if it's even a soviet one though...

At 2.26 is a 21 firing the 73.

MiG-21Bison has R73/HMS and also R77 capability. They also have a VERY capable and nasty jammer-pod.

 

I have not seen the R73 on the Romanian MiG-21 Lancer, but I think it is compatible. The Lancer is leaning more towards A-G. I have seen some videos but only when shooting R60MK and

R-13M1.

[Chizh]

Original MiG-21bis never use R-73.

Mig21bis never used the KH66 Grom......

 

and yet.....

 

 

besides another user pointed out the Cuban Mig21BIs is a legacy one, Not a 93/Bison, and is compatible with the R73.

 

If thats actually true for the Cuban Mig, then it does not seem fantasy or so far fetched.

A little re search shows it did have the kh66 grom please dont make me post the source :)

Are you really sure?. It's depend what you mean when you saying "original": aircraft from 1972 ( production start ), or aircraft with original weapon system but still in use?. For me original aircraft means original electronics inside. Cuba aircrafts have original weapon system, but they got simple upgrade with R-73 ( are not MiG-21-93 ). I'm sure those missiles have no connection with the weapon system, are just fired boresight ( precisely the same way like R-55/R-60/R-60M working beside aircraft's weapon system ). Only three missiles were part of the original weapon system ( what means that radar calculates launch zones )R-3S, R-3R and R-13M , all rest was just simple upgrade and only electric circuits were added. Here the photos:

 

 

 

Coxy if you will find at least one photo of Bis with H-66, I will buy you that aircraft :).

I agree we should stick to what is realistic, but if the difference is just the launcher, without the need for extra electronics, I see no reason not to have access to the R-73.

[foxbat155]

I think that problem is much bigger, whole module is light years far from realism.:music_whistling:

nope this was countered multiple times in these forums. So you should not be making false claims.

 

the BIS shouldn't have the KH66 or R2, because its using the RP22 ( specifically RP22M) radar. (monopulse radar)

Its pretty obvious LN simply decided to make concession to gameplay just like with the Tracking pipper when in IR mode ( though the latter can be disabled in main menu settings)

 

 

So IF Cuban Mig21Bi's can (or have been wired) use R73s then R73 is more plausible on the Bis the the inclussion of the Kh66 and R2 missiles.

I agree, R73 should be available for MiG21.

 

Im not at my PC atm but iirc we have Cuban skin ingame.

[jackmckay]

^ Agree on that.

[asla36]

And then why not add R77s, A/G radar, glass pit, etc? All those things were available on the MiG-21. The problem comes with the fact that we have a MiG-21bis, and not a MiG-21-98. And IT didn't have any of these. If you don't count the ability to very roughly lock a ground object as A/G radar that is.
