Sukhoi Su-30MKI

That reminds me....are they planning to add plumbing for drop tanks as part of the upgrade? There was some talk about it a while back iirc.
 
11.3 ton is for Su-35S. MKI is based on old Su-27M(Su-35/Su-37) that had around 10.25 tonnes of internal fuel. MKI's internal fuel capacity was always presented as 9.64 tonnes. In-reality it could be around 10 tonnes, but that's about it.
Well, people can visit the edit-history & see how many times the values have changed. It is very confusing for public which website to trust.
IAF doesn't seem tohave a specs page of current jets, does it?
BTW, any idea how much internal fuel J-16 would have?

Su-30MKK's airframe was also derived from Su-27M program(UB Variant), so it also has 10.25 tonnes of internal fuel. J-16 being Chinese version of Su-30MKK seems to have equal internal fuel capacity.

We need to remember that this 10.25 tonnes is the "maximum' limit that any Flanker version(minus Su-34) can carry internally. Su-35S has almost 11.5 tonnes because its airbrake was removed and replaced with an 1 tonne fuel tank. So ~10.3 tonnes + 1 tonne= Near 11.3 tonnes fuel it carries internally. Hope it helped you and your confusion is clear now👍

Also, don't worry about Wikipedia edits as most can do it, lol.

Most people can edit tht's why it is a thing to worry 🤣
Since the 1st variants of Su-27 till today's Su-35, the airframe dimensions & volume have remained somewhat constant, but electronics & other components have become compact. But that space may have been filled up again by more RF & EO sensors, avionics, HVAC/ECS system, etc.
We don't know what the Chinese have done with J-16 since MKK.
And 1-seat Vs 2-seat further adds to number guessing. :unsure::rolleyes:🤪
Anyways, based on Google search, Wiki & your update, currently i'm considering the internal fuel weight of some Sukhoi derived jets as following:
Su-30MKI, 2-seat - 9.6 tons
J-16, 2-seat - 10.3 tons
Su-35, 1-seat - 11.5 tons
Su-33 (Navy), 1-seat - 9.5 tons
J-15 (Navy), 1-seat - 9.5 tons

MKI has 9.6T because there's a second pilot in place of a 1T tank compared to Su-27. Su-35S adds a tank in the spin in lieu of the airbrake for an additional 1T tank.

Su-30MKK/J-16 has 10.2T. They managed to put fuel in the vertical fins and enlarged one of the fuselage tanks by a few hundred kilograms. So that's 600 kg extra in total.

I had always hoped the MKI MLU will see the removal of the airbrake for an extra tank, but I don't think the IAF will go for it. The Mig-29 UPG has a CFT on the spine.
 
Take it for what it is:

Original Su-27 had 9.4 tonnes of internal fuel. In the Su-27M program they increased the fuel tanks to the extreme part of the wings and also put fuel tanks in the vertical tails(around 250kgs). So it had 10.25t internal fuel capacity.

As per "Andrei Fomin"(apparently he got briefed by Sukhoi themselves), MKI has around 10 tonnes of internal fuel, even if it hasn't got those tail mounted tanks. With those it will have identical fuel load as Su-30MKK(10.25T). But there are things about MKI program that are still secret after literally 2 decades post its contract signing. So🤷‍♂️

So MKI's internal fuel capacity could be anything between 9.6t to 10.25t. Take 9.6t as safe bet and leave rest to;)

PS: In the MLU, we could plumb few hard points to carry EFTs and thus enhance its range even further.

Ok guys, Su-30 MKI & J-16 i'm considering 10.2 tons.
What about 1-seat Su-33 & J-15? They don't have 1 ton benefit in place of 2nd seat?

If you dig down the history of Flankers then you'll notice that single seater vs dual seater never had any fuel difference. Both Su-27 and Su-30(based on trainer Su-27UB) had the exact same 9.4 tonnes internal fuel capacity. Why? That's because the fuselage area behind the second seat is raised over the single seater variant to provide better visibility to the second pilot and to keep the fuel load the same.

So Su-33 and J-15 would also fall somewhere between 9.4t - 10.25t. Btw, my guess for MKI would be around 10t. But just take 9.65t as face value and a safe bet.

Su-30MKI and Su-30MKK/J-16 are different. They are both made by different manufacturers; Irkut and KnAAPO/Shenyang resply.

The basic Su-27 had 9.4T, Su-27K had 9.5T, the same design was used on Su-33.

Su-30M and Su-27M (the first Su-35) came with bigger internal tanks, with Su-27M adding an extra tank followed by the second Su-35 (Su-35BM/Su-35S) adding another tank. KnAAPO's Su-30Ms kept increasing the size of their tanks and later added new tanks in the fins for export jets.

This is what my low IQ brain could do. 🤪 I took 1-seat & 2-seat versions diagrams & superimposed them.
The orange area equipment was moved to blue area or vice versa.
So Su-30MKI = 9.6 tons; J-16 = 10.2 tons; Su-33 & J-15 = 9.5 tons. Everybody agrees now? :LOL:

The original Su-27 couldn't pull 9G with full fuel load. In the Su-27M program, they looked towards this issue and strengthened the fuselage and made the wings thicker. That also allowed better internal fuel volume.

All the changes/improvements of Su-27M program was implemented on MKI as well(also bettered).

Look at the clarity of the reporting by an external news agency. It summarizes everything recent about MKI without wasting any words. It even mentions how the Russians have moved on to the AL-41FS. We no longer have such a level of professional reporting in defense journalism.

India orders hundreds of new engines for Su-30MKI fighters


The backbone of India’s fighter jet fleet is the Russian-designed Sukhoi Su-30MKI, and the country recently ordered 240 engines to keep the fleet airborne for years to come.

Following approval by the Cabinet Committee on Security earlier this month, officials signed a deal with state-owned Hindustan Aeronautics Limited (HAL) to supply the so-called AL-31FP engines.

The contract, worth more than 260 billion rupees or US$3.1 billion, will see the first engine handed over to the Indian Air Force (IAF) after a year. All will be delivered within eight years, according to a Ministry of Defence statement, with production of 30 annually.

Made by HAL under Russian license, the engines currently feature local content of 54%. However, the company plans to boost the ratio to 63% by tapping India’s defense manufacturing ecosystem. “This would also increase the indigenous content of repair and overhaul tasks of the aero engines,” said the ministry.

It further stated, “These aero engines will be manufactured by the Koraput Division of HAL, and are expected to fulfill the needs of the Indian Air Force to sustain the operational capability of the Su-30 fleet for the defense preparedness of the country.”

Notably, India chose to stick with AL-31FP engines, even as Russia is upgrading its Su-30SM fighters with the newer and more powerful AL-41FS.

Incidentally, the IAF is buying twelve new Su-30MKIs from HAL for $1.3 billion to make up for losses. This purchase was approved in September 2023.

The air service has approximately 260 Su-30MKIs, six of which traveled to Exercise Pitch Black 2024 in Australia in July. The Indian detachment commander, Group Captain Ajay Rathi, praised the platform: “With its advanced avionics, thrust vectoring and superior payload capacity, the aircraft is capable of undertaking offensive and defensive missions, to execute strategic and tactical operations.”

He described its key capabilities as its long range, maneuverability, firepower and effectiveness in contested environments.

Last November, India’s Defence Acquisition Council signed off on a major upgrade program for 84 Su-30MKIs. HAL Chairman and Managing Director C.B. Ananthakrishnan subsequently told The Economic Times: “The upgrade will see significant private-sector participation, with HAL as the lead integrator.”

Air Chief Marshal Vivek Ram Chaudhari, the Air Force’s top officer, said the project would upgrade 51 aircraft systems, with 78% of the content being indigenous. HAL is responsible for 30 elements, while the private sector will upgrade eight systems.

Once implemented, the upgrade will include installation of the Virupaksha active electronically scanned array radar, a new electronic-warfare system, and a domestic infrared search and track system.

Armenia seeks India’s help to upgrade its Su-30 fighters

(HT_14.09)

The development comes on the back of Armenia ordering rocket systems, artillery guns and weapon locating radars from India​

Armenia, which has fought two wars with Azerbaijan since the collapse of the Soviet Union, is seeking India’s help to upgrade its small fleet of Russia-built Su-30SM fighter aircraft, with the development coming on the back of the country ordering rocket systems, artillery guns and weapon locating radars from India, top officials aware of the development said.

The Su-30 upgrade that Armenia is eyeing involves avionics, electronic warfare suites and weapons.

“We are looking at modernising our Su-30s with the help of Hindustan Aeronautics Limited (HAL) as it has a lot of expertise in the field,” Colonel Hovhannes Vardanyan, who heads Armenia’s Air Force Department, told HT on the sidelines of multilateral Tarang Shakti 2024 air combat drills that concluded at the Jodhpur airbase on September 13.

HAL has built the Russian-origin fighters for the Indian Air Force under licence at its aircraft manufacturing division in Nashik.

Vardanyan spoke through an interpreter.

Vardanyan said he discussed areas of possible cooperation with chief of defence staff General Anil Chauhan at the International Defence Aviation Exposition 2024 organised at the Jodhpur airbase alongside the exercise to showcase India’s prowess in the defence manufacturing sector to top officials of 28 global air forces that participated in the drills.

A top Indian official confirmed Armenia’s interest in the Su-30 upgrade by HAL.

“There’s some conversation happening around that, but it’s at an initial stage. The Su-30 variant operated by Armenia is different from the Su-30MKIs in IAF service. So that aspect must be factored in, along with the complicated dynamics in that region, including India’s longstanding and trusted defence partner Russia moving closer to Azerbaijan after the war with Ukraine began,” the official said asking not to be named.

The mountainous region of Nagorno-Karabakh has been the focal point of tensions between the two former Soviet republics.

Russia traditionally stood with Armenia but drifted towards Azerbaijan after the war with Ukraine began as Moscow needed Turkey’s continued support, a country that has close links with Baku, said Anil Trigunayat, a former top Indian diplomat and Russia expert.

“Russia is going slow on Armenia and the US is moving closer to Yerevan. Despite the changing dynamics in the region, I believe India will keep military cooperation with Armenia on track,” Trigunayat said.

India’s defence ties with Armenia have deepened in recent years.

In November 2022, Indian defence firm Kalyani Strategic Systems Limited won an export order worth $155.5 million for supplying artillery guns to Armenia, the first order for a local company for the 155mm weapon system. Kalyani will execute the order by 2025. That order came on the back of Armenia choosing to buy the Pinaka rocket system from India.

Armenia turning to India for the Su-30 upgrade is hardly surprising.

IAF operates a fleet of 260 Su-30s and will get 12 additional fighters to make up for planes lost in accidents. The first 50 Sukhois came from Russia, while the remaining were built under licence by HAL.

IAF’s Su-30s will also be upgraded by HAL at a cost of around ₹65,000 crore. It will involve equipping the fighters with the indigenous Uttam active electronically scanned array (AESA) radar, electronic warfare suites, weapon control systems, avionics and new weapons.

Besides, HAL is building Su-30 engines at its Koraput facility in Odisha. On September 9, the defence ministry signed a ₹26,000-crore contract with HAL for 240 aero-engines for IAF’s Su-30s. The state-run firm will supply 30 AL-31FP engines every year, with the delivery to be completed in eight years. /end

If I didn't know better I'd say it has all the imprint of the AL-51 all over it . Or at least it's benefitted quite a lot from that program.
