Yes not only cockpit canopy. But a whole range of service problems.
That is why the Mig-31BM and BM2 overhaul/upgrade is now happening.
some 120 units.Those figure of yours is cherry picking at best. Sure if F-16 is clean and Foxhound is heavy with fuel weapons.
Try turn it around a bit.
I suppose cherry picking is why I put the MiG-31 7,000ft lower in altitude. Turn that round a bit.
LOL. You’d better say you don’t know why these jet fighters get refueled so many times.
Reading between the lines, they seem pleased they suffered no issues refuelling, so my conclusion is that they used the trip as a practice, so it’s a bit like the ’27 kills in a single sortie’ – all in the name of training.
The Mig-31 can indeed out turn an F-16, if they go high enough.
The F-16, wont be operating in such hight anyway. Which put a negativ NEZ on its missiles, trade altitude for range.Gotto love the Foxhound. Its designed to operate down low to engage low cruise missiles.
But it has the juce to go high as well.
High enough, as in near the F-16’s service ceiling. Won’t happen at 40,000ft though.
https://info.publicintelligence.net/HAF-F16-Supplement.pdf
At 40,000ft, M1.2 an F-16 can top 6g and 9.5deg/s, 4deg/s sustained. The MiG-31 can pull 5g at low altitude but that gradually reduces down to 3g at 55,000ft (Combat Aircraft July 2015). It’s top speed is also restricted to M1.5 due to the cockpit glazing. Also the F-15 has a sustainable turn radius of 10,000ft at M0.8 at 40,000ft. Like I said, the MiG-25/31 is an effective aircraft but its best course of action will always be hit and run.
MiG-31 sustained turn rate at 33,000ft is 3.7deg/s.
Distance of 5960 km, 8 hours of flight, the average flight speed of 745 km / h. Seven air refueling, on eight sites 745 km.
Suppose that the plane refueled at 50% fuel in the tank. It turns out (8382 kg / 2): 745 km = 5.63 kg / km…F-35A 8382 kg : 2200 km = 3.81 kg/km or 8382 kg : 1850 km = 4.53 kg/km…
F-22 9367 kg : 2500 km = 3.75 kg/km
So now the plane only has a 1490km range.:highly_amused:
Perhaps the whole point of the event was to practice refuelling.
Why does the mention of F-35 turn off some people’s thinking gear? 39% fuel fraction, oh 1,490km seems like a plausible range.
I think it’s thrust specific fuel consumption. It doesn’t matter how many engines. At any rate, then, the claim is that the T-50’s engines are a bit over 10% more efficient than the F-35’s engine.
It’s a wonder airlines aren’t ordering their engines with their jets then I guess.
Calculation. For the fourth-generation aircraft range is obtained less real

When I look at the sources of this “info”, I am not sure if I want to read more of it.. that cuttingedge looks like a webpage for mentally incomplete and acig is known to be notoriously wrong. :confused:
One of the quotes is from the BBC AND all 3 quotes tally!
Ah but those could be said for F-5A and F-5E as well; latter has longer fuselage, different wings and LERX, more powerful engines etc etc.
It would be a great counter to F-4E AIM-7M combination; 4x similarly ranged BVR missiles, arguably better radar, better maneuverability and far better acceleration on a smaller airframe.
Because again, it faced much more modern adversaries.
Wing loading is meaningless without lift coefficient graph, TWR is meaningless without L/D graph. Why bother? F-4E manual is on the net, so is MiG-21 manual and some pages from MiG-23 manual.
Well that is the handicap of being a follower instead of the leader. Advantage is they spend far less money on the aircraft, because they don’t push their resources to build the best aircraft. They have a certain performance goals to match and exceed in their designs.
They are generally accepted “labels” throughout the aviation.
I disagree, MiG-25 was a flying brick throughout its flight envelope and had no look-down shoot down capability. F-14 and its counterpart MiG-31 are actually quite maneuverable in their respective domains; ie, an F-16 wont outclimb or outmaneuver a MiG-31 when they are sufficently high and fast; numerically speaking, at 12000 meter (39,3k feet) a MiG-31 can sustain 5,6 deg/s at M1.4 and F-16 can barely sustain 4 deg/s at same conditions, with no missiles and ~25% fuel. At 40k feet, same clean F-16 is phi-max (max aft stick) limited, its maximum G capability at M1.3 is 5Gs, climbs to ~5,5Gs at M1.4, so “5G limit” of MiG-31 is not an disadvantage, too. If MiG-31 refuses to descend or slow down, a MiG-31 can easily turn with an F-16 in a gunfight at 40k feet; and probably win.
Well its not about the fairness about a specific date and time. You are making a technical capability comparsion between US and Soviets.
You can’t base an argument on “war isn’t fair” and chose a specific time to make such comparsion; a time that would support your claims. Lets talk about 1990 then? A time when;
-All Su-27/30s were flying with R-27RE/TE + R-73s, but F-15A/Cs were still flying with AIM-7M+AIM-9Ms.
-All MiG-29s were flying with R-27R/T and R-73s, some even had internal ECM whereas F-16s had pathetic radar and they were even lacking BVR capability altogether, solely capable of using AIM-9M.
-MiG-31 had Zaslon, only PESA fighter radar back then, againist ageing F-14s with its AWG-9, and it was faster and longer ranged (supersonic) then its contemporary.
-Majority of MiG-23s were upgraded to ML/MLD levels, with true look-down shoot down radar and better R-24 missiles.In fact, apart from legacy F-4E and Tornadoes with AIM-7s and Mirages with Super 530s, no airforce in Europe had fighters with BVR capability.
If all hell broke lose back in that day, it would be an easy “walk over” by Soviet airforce againist NATO.
Not really, the F-18C to E difference is far more extensive as the diagram shows. The SH is about as close to an F-18C as an Su-27 is to a MiG-29.
It would but unfortunately time machines don’t exist. The MiG-23 arrived 10 years after the F-4 and only 4 years before the F-14 and the F-14 wiped the floor with it during the 1980s (Iran-Iraq War and Gulf of Sidra incidents).
‘Much more modern’, as in 4 years more modern, whereas wyou wish to compare it with a 10 year older aircraft. Crazy thing is, it didn’t really do that great even against the F-4.
Not really, the others factors are broadly similar so wing loading and TWR provide good 1st order estimations.
Unfortunately that philosophy leaves you with worse aircraft the vast majority of the time though, leading to far reaching excuses as to why the combat performance of said wares was less than successful, e.g. monkey model supplied for export, stupid operators, items had past sell by date etc.
Irrelevant, you can’t fight a war with what you don’t have at a given time and I don’t really think they are that widely accepted anyway.
IIRC the MiG-31 is limited to the same 5g that the MiG-25 is. Don’t confuse g capability with deg/s or turn radius. There’s your mistake. The MiG25/31’s best course of action against any fighter is to fire from afar and then run.
Yes, and technical capability has to be time specific, otherwise I could compare a Sopwith Camel with an F-22.
Err… wrong again. The R-77 only entered service in 1994, the AIM-120 achieved its first kill in 1992, with the C version arriving in 1994. Aside from that, the US had an ARH missile in 1974.
MiG-29s – didn’t do them any good during Desert Storm.
F-14 had AIM-54C though and you hardly need a PESA radar to detect MiG-31s. And super wrong again, the AN/APG-71 came out in the 1980s.
The F-4J was the first aircraft with look-down shoot down in the early 1970s.
Apart from say the Tornado F3s with Skyflash you mean? Or the Mirage 2000s with Matra Super 530s?
Pffft…. As I’ve said, the combat performance of each others wares says otherwise.
My version, 1391 km (751 nautical mile) – range with external tanks. 1391 km * 2 = 2782 km
Amazing how the haters believe an aircraft with a 39% fuel fraction (same as Su-35) only has a 2,200km range, yet PAK-FA with 35% – 5,400km.:highly_amused:
Those expecting the PAK-FA to do over 4,000km on internal fuel, and the F-35A to do less than 3,000km, are in for a really unpleasant surprise when reality strikes.
Let’s compare the empty weight and the weight of the fuel, they do not change.
Su-35S, empty 19,300 kg, 11,500 kg of fuel, 11,500: 19,300 = 0.596, range 3600 km
Su-30MKM empty 19660 kg, fuel 9640 kg, 9640: 19660 = 0.49, range 3000 km
F-16, empty 8910 kg, 3228 kg of fuel, 3228: 8910 = 0.36, range 2,500 km
F-15, empty 12975 kg, fuel 6105 kg, 6105: 12975 = 0.47, range 2,200 km
F-18, empty 11340 kg, fuel 4903 kg, 4903: 11340 = 0.43, range 2,200 km
F-22, empty 19660 kg, fuel 9367 kg, 9367: 19660 = 0.48, range 2,500 km
F-35A, empty 13290 kg, fuel 8382 kg, 8382: 13290 = 0.63, range 2,200 km
Right so the F-35A is highest there, so it’s obvious the range is not 2,200km. The F-22 is also 21,500lb (total fuel, usable is what’s given by Lockheed presentations, tank capacity is roughly 13,031L but some is empty). I also have a feeling you’re using usable fuel rather than full fuel for the F-15 too.
PAK-FA, empty 39,680lb, fuel 22,700lb, 0.57.
F-22, empty 43,340, fuel 21,500lb, 0.50.
Here is a slide from a early 2016 Briefing
From RAF Akrotiri in Cyprus you could hit most of the Middle East, even with the B.
Why don’t you work with the radius provided in the official information from LM?
As I’ve already mentioned, that is actually a known number. Based on radius, I guess range is about 2500 – 3000 km.If were talking ferry range, fuel fraction is ~ 0.38, same as Su-35, from what is known at least.
No external fuel for the F-35.
We now know this though:
Range of flight 2,200 km – the official information from Lockheed. Really can be smaller – 1,850 km.
Maximum take-off weight of F-35A with external fuel tanks 31750 kg. internal fuel 8382 kg. The relative weight of 8382 kg Fuel: 31750 = 0.26Realistically attainable takeoff weight of F-35A:
13290 (empty) + 100 kg (pilot) + 8278 kg (or 8382 kg fuel) + 89 kg (cartridges) + 6307.6 kg (weapons) = 28065 kg or 28169 kg
6 GBU-31 + 2 AIM-120C + 2 AIM-9X = 6 * 969 kg + 2 * 161.5 kg + 2 * 85.3 kg = 6307.6 kg8382 kg : 28169 kg = 0.298
Aerodynamic quality – 8.8 (calculation). Consumption – 0.7 kg / kgs * hT-50
fuel weight of 11,000 kg, maximum takeoff weight of 34,000 kg. The relative fuel weight of 11,000 kg : 34,000 kg = 0.32
Aerodynamic quality – 12.2 (calculation). Consumption 0.62 kg / kgs * hFlight range without external tanks 3000 – 3500 km
With two external fuel tanks 4000 – 4300 km
Repeat calculation using 10,300kg for PAK-FA fuel load and 8,410kg for F-35A.
Also, why the hell would an F-35 be carrying 6.3 tonnes of load? How about you replace that figure with 6 AIM-120s, circa 900kg?
A2A take off weight for F-35A is 49,540lb = 22,518kg for PAK-FA it’s 64,530lb = 29,331kg.
18,500/49,540 = 37.3%
22,700/64,530 = 35.2%

Su-50? There is no such thing.
The T-50 might enter service as Su-37, Su-39*,… or even Su-50, if the Russians follow the US marketing BS. But right now, it is the T-50* Yeah I know those numbers are already taken, but I have no idea if 37 and 39 are official designations or just marketing from manufacturers.
I know, I’m guessing at that designation.
so all this hate I keep hearing about the F-35
is it directed at all versions or just the B version?an article elsewhere said only the USAF is singing praises about its performance. so perhaps the A version is doing well?
Well based on this, the B’s range is likely to be a lot better than expected too. Based on 751 * (467/625) it works out to 561nmi (1040km) radius for the same mission profile. And if we take 3,000km as the Su-30’s range, the F-35A works out to 3,000 * (751/728) = 3,100km and the F-35B works out to 3,100 * (467/625) = 2,320km clean.
