Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 1)

1- Except the “different figures” are for different aircrafts (Su-32 and Su-34E).

Su-34E is listed to have 1100 max speed on the deck without external stores on the UAC website.

It’s listed to have 1100 max speed on the deck with 4x AAMs (most likely 2x R-73 + 2x R-77 based on the other picture and common sense).

2- And as I said, it’s not even clear if the picture is authentic …

3- And even if it is, it’s not like 2x R-73 + 2x R-77 has a huge impact on max speed on such huge airframe …

4- And this is all assuming that the limit is due to thrust/drag.
If it’s due to the structural limit it would make sense that 4x AAMs would have no effect on it …

I could be wrong, but i don’t remember a single 2nd or 3rd gen aircraft (much worse airframes) that had afterburners and couldn’t reach such speed, like it’s just too absurd, the design must be so flawed to not be able to do that it’s not even funny…

I’m not saying it’s impossible but we had some sources supposedly contradicting themselves (1400 x 1100) and now there’s this document showing that it’s the indicated speed, that mixed with a bit of common sense makes me inclined to believe that this confusion was pretty much solved… But let’s see what the devs will say anyway.

IIRC the su-32 is for the su-34 what the t-10 is for the su-27, i’d be really surprised if the fullback is just THAT worse…

The funny thing is that such draggy and huge bomber with relative lower T/W is reaching speeds as high as things like Typhoon, Rafale and F-15 on the deck …

Which source contradicted itself?

* Random picture somebody uploaded on the forums

And?

Indicated vs true airspeed makes no difference on the deck

Su-32 was supposed to be the original export Su-34, but for some reason the designation was changed to Su-34E later.

I’m not sure what the difference is, but the Su-32 designation alone can be indicative of older information or perhaps a slightly different airframe.

Either way, the authenticity of the document is not clear …

The 1100 ones vs the old 1400 ones

@ZVO_12_INCH can you provide us the source?

Well it doesn’t exactly reach phenomenal speeds on deck but the mig25 is prolly aviation’s biggest boat of all time and, well, it goes crazy at high altitude…

Speaking of the 25, i think i’m more excited to see it on the next updates (one can dream) than another sukhoi lmao

At this point i feel like that guy its a joke.

Such huge bomber.

Well like i said not being able to go beyond 1100 kph in a 4th gen aircraft is just crazy, even early bombers can reach that…

Flankers are big in general tbf, and that looks like it’s barely bigger than an Su-35 (20% bigger?)

It has the dials MFD page from the Su-30SM

But the RWR one is unfinished, and the strategic view and weapon loadout ones are still placeholder.

The thing its like 3.5 tons heavy than the Su-30sm but it have better engine. Take a kit full of R-27ER that its almost 2 tons and check the speed.

edit; A 24500tons+fuel Su-30sm. That its heavier than Su-34 (empty weight) with worst engine.

Edit2; same config at alt.

But but… Such Huge Bomber… bs

bonus i broke the wing on this thing while writing.

Su-30SM is also too fast

It should have a max speed of 1350 kph on the deck

Cross sectional area is one the main factors that affects drag.

Just look how “chonky” the Su-34 is compared to the two other aircrafts.

The engines are barely more powerful than Su-30SM, and they are weaker than Su-35.

Sure by the info on these Su-30SME based on old Indian Su-30k retrofitted… Right? sure sure…

Yeah yeah, HUD, RWR, MFD and IFF equipment etc affects your max speed …

I have no doubts about the data from Sukhoi’s website!..
Compare…

The 1400 km/h limit is most likely a strength limitation for the T-10 family… .
3.We like to confuse people with the names of aircraft…

I mean if they’re heavy, they kinda do?

It’s not like one variant has no equipment.
The avionics are just different models / from different origins.

Weight difference is gonna be minimal, and the biggest factor for top speed is drag (external airframe shape and size), rather than weight.

I mean weight also affects drag you know. Can’t really discount it as a factor. Also aren’t these values just as good as stat card values? It’s not like the Su-30 would fall out of the sky the moment it hits max speed
