Internal carriage?

Only a bomb bay and two small ones for short range missiles.
F-35 carry two medium ones, 6 in total against 3 medium and 2 short range.
And in A2G mission it is limited to carry only short range ones.
IMHO the most disappointing feature of whole plane.

TASS news agency under the heading " Checkmate". Designer Strelets: the new fighter will surpass all world analogues " published an interview with Mikhail Strelets, First Deputy Managing Director - Director of the Sukhoi Design Bureau and Chief Designer of a promising Russian light single-engine fighter of the fifth generation under the LTS program (" Light Tactical Aircraft ") Mikhail Strelets. Official presentation of the LTS aircraft under the commercial name Checkmate took place on the first day of the MAKS-2021 International Aviation and Space Salon in Zhukovsky on July 20, 2021.

On the first day of the MAKS-2021 air show, the United Aircraft Corporation (UAC, part of the Rostec state corporation) held a presentation of a new light tactical aircraft (LTS). The single-engine fighter was named Checkmate (translated from English - "Checkmate"). According to the announced information, the newest combat aircraft includes all the most advanced developments, including an open architecture of construction in the interests of the customer and unique artificial intelligence technologies.

First Deputy Managing Director - Director of the Sukhoi Design Bureau, Chief Designer of LTS Mikhail Strelets in an exclusive interview with TASSon the sidelines of the air show in Zhukovsky, he spoke about the advantages of the latest Russian fighter over foreign counterparts, the role of artificial intelligence in the operation of the aircraft, and also about when Checkmate will make its first flight.

- Mikhail Yurievich, what are the main features of LTS Checkmate?

- LTS Checkmate is a new light tactical fighter that we are developing on our own initiative. The main features of the project are a unique combination of flight performance, combat capabilities, low visibility and cost of a flight hour. The aircraft is a versatile, adaptive platform with an open architecture. It can be made in several configurations in accordance with the wishes of the customer.

LTS Checkmate has characteristics that are unique for its class. For example, it has the largest flight range for "light" aircraft and the duration of loitering when searching for a target or waiting for target designation, the highest carrying capacity, as well as the best characteristics of onboard equipment. Today we will be able to offer practically any modern system of onboard equipment to the aviation market.

The new aircraft is equipped with an ergonomic cockpit equipped with advanced electronic equipment with elements of artificial intelligence. This allows you to significantly reduce the workload on the pilot and focus on the destruction of ground and air targets.

In addition, LTS Checkmate has the lowest cost on the market relative to aircraft of similar functionality. In terms of its technical characteristics, it must surpass all existing analogues.

- Is the new aircraft an upgrade or a project from scratch?

- LTS Checkmate was designed using the scientific and technical groundwork obtained during the creation of the fifth generation Su-57 combat vehicle and with the widespread use of supercomputer technologies. In fact, it is the first Russian aircraft to be fully digitally calculated. This significantly reduced development time and technical risks during testing.

At the same time, proven technical solutions are incorporated into the machine and a high potential for modernization is provided. Together with our existing aircraft, this will allow us to quickly create a flexible combat aviation system of the future and to respond most efficiently and adaptively to emerging threats.

- When will the first flight of the new aircraft take place?

- The aviation complex has been designed, its characteristics have been confirmed by a full range of virtual tests, and strength static tests will soon be carried out. The first flight of the LTS Checkmate is scheduled for 2023.

- Tell us about the after-sales service of this machine.

- Reliability, convenience and ease of maintenance are one of the most important qualities of modern aviation complexes. The aircraft is designed in such a way as to simplify personnel access to systems as much as possible without special aerodrome equipment. The fighter is equipped with an integrated auxiliary power unit.

Also, thanks to the artificial intelligence of the cockpit, pre-flight control no longer requires a human presence. These solutions will make it possible to prepare a combat vehicle for launch in a short time, even in the absence of special means, which, in turn, will affect the combat survivability of the entire fleet.

The LTS Checkmate is a truly easy-to-maintain aircraft. A new automated logistics support system Matreshka has been created for the fighter. Using the latest predictive analytics methods, the system will track the technical condition of the aircraft in real time throughout the entire life cycle. This will make it possible to plan preventive and repair work, significantly reduce costs and increase the efficiency of after-sales services.

- Tell us more about the pilot's intelligent support system.

- We follow modern trends, and today the cockpit has an intellectual support for the crew, which forms hints to the pilot for the most effective actions in air combat, including in difficult situations.

LTS Checkmate is equipped with artificial intelligence, acting as a "co-pilot". He will independently carry out diagnostics of all aircraft systems and help the pilot in a rapidly changing combat situation. The commander concentrates on issuing instructions, the machine performs all operations automatically.

In addition, the cockpit of the fighter is equipped with unique panoramic touch screens that reflect the status of all systems, as well as provide comprehensive information about the route, targets and threats.

- What is unique about the airborne equipment complex (OBE) of the aircraft?

- OBE of the fifth generation, installed on LTS Checkmate, is a separate pride of the developers, it is a modern platform with a reserve for the future. It includes a wide-range all-aspect review system that will instantly alert the pilot of threats.

The complex allows you to exchange information with other combat units. OBE has high characteristics of noise immunity. The aircraft is equipped with an integrated electronic countermeasures and defense complex, which will not allow the enemy to detect themselves and use weapons.

—What kind of cargo can Checkmate LTS carry?

- The LTS Checkmate has the most capacious internal armament compartment among the aircraft of its class, which allows the use of a wide range of aircraft weapons (AAS) in an inconspicuous fighter configuration. In addition to classic missiles and bombs, it is possible to install additional fuel tanks, suspended cannon containers, as well as other cargo for various purposes in the compartments. Thanks to the spacious compartments and the presence of external suspension points, the aircraft has a record-breaking payload for this class - 7400 kg.

- What ensures the low cost of a flight hour in comparison with other aircrafts?

- The low cost of a flight hour is made possible by perfect aerodynamics, modern engine and on-board equipment, as well as minimization of aircraft maintenance costs. Compared to its main competitor - the F-35 - LTS Checkmate will receive seven times less cost of a flight hour.

- How many goals can simultaneously track and attack LTS Checkmate?

- aircraft equipment with built-in radar AFAR (active phased array antenna) is able to attack the six and track up to 30 air targets. If we talk about land and sea, then LTS can accompany two targets at the same time.

- Is it possible to install imported equipment on board the Checkmate LTS?

- The aircraft is designed with an open architecture, therefore, if the customer wishes, it is possible to install modern foreign-made onboard equipment on the Checkmate LTS. The adaptability of the aviation platform allows the fighter to be configured in such a way that it fully meets the customer's tasks.

- In what options can an aircraft be created?

- In accordance with the wishes of the customer, the new fighter can be in two-seat, optionally piloted and unmanned versions. LTS Checkmate was conceived as a platform with modular modification potential. This is realized by replacing the fuselage head and adapting systems at the factory.

- Do you plan to jointly use Checkmate LTS with unmanned aerial vehicles?

- Both the manned versions of the Checkmate LTS and its unmanned modifications are capable of operating in a network-centric combat system, that is, working as part of a group of manned and unmanned aircraft. We plan to carry out such tests.

Or 2014/15 at MP.net covering the civil war in Ukraine. Astonishing speed and depth of coverage, now lost.

Atmosphere wrote:An empty gripen weighs less than 7 tons.
This aircraft is smaller, with inevitably lower weight of the components and probably even structural materials due to the inevitable lightening that cames with the massive time gap between the two planes, and the fact that checkmate derives dieectly from one of the highest profile projects the UAC has been involved with.

So with that in mind, even the 15T class 117 would give it very high t/w, let alone Izd.30 which would turn in into a controllable rocket rather than an airplane.

I mean imagine 18-19T of thrust for an airplane that would weigh no more than a gripen. With the advantages that would come with less control surfaces, advanced flight controls, and 40 years of aerodynamic refinment since the Su-27.

We don't have actual values and technologies/materials are a complicated thing (for instance, the 8g structure should not be that heavy), but this plane is probably 40-50% heavier than a Gripen. I doubt the izd. 117 is not going to move it like it moves the Su-57 currently, the TWR will probably be close to that of the F-35 or even lower.

Marcellogo wrote:They gave a number of 7,4 tons: F-35 is 9,5 ton

Well F-35 carries 8. something tons. But still that is a LOT, very difficult to see that in reality, and the plane would be challenged to move. Planes that don't carry EFTs don't actually need such absurd payload capability, more than 5-6 t in bombs is a crazy amount.

Internal carriage?

Only a bomb bay and two small ones for short range missiles. No No No
F-35 carry two medium ones, 6 in total against 3 medium and 2 short range.
And in A2G mission it is limited to carry only short range ones.
IMHO the most disappointing feature of whole plane.

Did you see it properly? F-35 carries 2 smaller A2G weapons than what LTS carries, plus 2 missiles. They are trying to include 2x AAM more, true, but it is not there yet, and it will take time. But as of now, LTS would carry more AAM than the F-35 in a A2A loadout or the same amount with bigger weapons in A2G configuration. What is not clear to me is whether the side bays are only for SRAAM or MRAAM too, from the size it may be the second option. The ventral bay is more regular and usable than that of the F-35, with better development options for new weapons like for instance the multimissile we discussed here.

@LMFS

How many Kh-58/59 in total it can carry?

dino00 wrote:@LMFSHow many Kh-58/59 in total it can carry?

Two of them, in one WB sized (apparently) like that of the Su-57. Those are very big and powerful missiles, it is quite an achievement for that kind of plane.

BTW:

"The engine will be in the 14.5-16 t class. This engine is made on the basis of the groundwork of the United Engine Corporation, and will be even more advanced on this aircraft," said Alexey Bulatov, Deputy Chief Designer of Checkmate, during the presentation of the machine.

https://tass.ru/armiya-i-opk/11947075

This sounds like the izd. 117 is going to be upgraded and be used as the export engine for this plane, not the izd. 30. Maybe that is the reason why we saw the serrated nozzle, even when izd. 30 is not there.

More:

As Yuri Slyusar, General Director of the United Aircraft Corporation (part of the Rostec state corporation), noted during the presentation, Checkmate will take off in 2023.

In turn, Bulatov said that the first flight will be performed by the machine presented at MAKS-2021. “There is a sample in front of you - this is not just a mock-up, this is not just a demonstrator. to start organizing the first flight, "Bulatov added.

Compared to analogues, Checkmate has higher performance. "If we compare with the American F-35 fighter, its closest analogue, this is a different aircraft. More speed, more range, greater payload. New qualities. Much better stealth is implemented here. I would not say that it is a correct comparison with any aircraft." It has a unique aerodynamic design, "Bulatov said.
Further development of the project

Several new aircraft will be created based on the Checkmate modular platform. "It is planned to develop several options, including unmanned and naval versions. Ship, unmanned, two-seater. Adaptation for these versions will be with minimal changes," Slyusar said. According to him, the production aircraft will be offered to customers in 2026.

The head of the UAC expressed the hope that the new light fighter and its unmanned version will be of interest to the Russian Aerospace Forces. He stressed that the aircraft is an initiative development, and negotiations are currently underway with the military department as a potential customer.

On this product, according to the interlocutor, the work of various systems and units is being worked out on the ground....


The first engine for the export version, the second stage for the Russian one, that's maybe Mack 1.8, versus Mack 2 previously mentioned by Suckoi

Atmosphere wrote:...So with that in mind, even the 15T class 117 would give it very high t/w, let alone Izd.30 which would turn in into a controllable rocket rather than an airplane...

Also quite a few potential customers would gladly opt for older engine in favour of saving money or buying more airplanes

I know for a fact that for Serbian Airforce engine power and supercruise are almost irrelevant considering the ranges involved and mission profiles

As long as it can go supersonic we are good, what matters is numbers and operating costs

Always like your posts but I highly disagree. I am almost sure the central weapons bay is very similar to that seen on su57. Three r77m and two r74/k300 missiles is impressive. On top of this there are four more external points to attach weapons. I also guarantee the central weapons bay could carry kh 69 cruise missiles.

[Billie Flynn] A: “So right we went from World War one the Red Bear and get the world war two like you're talking about p38 it's Spitfires it's against the great German pilot we get to Korea and fighter jets. we get to Vietnam same sort of thing we get to Top Gun thirty something years ago in that movie of dogfights.
That's not my world anymore.
I see the enemy 200 miles away.
They'll never see you you'll never get to look at an F-35 in a dogfight. Because, he will have killed you many many policies it's significant distances away and you'll never even know that it happened to you.”

I am assuming the nose size is small and the latest presentation they ever did was with fga-35 with 1000 modules giving a 250km performance range. So I am hoping its a new radar with higher performance. Even if the performance specs are close to F-35 I wont complain that much because of the costs of it and its intention for export, but the Su-57 is my king.

Note how these types who are always quick to correct against the notion that battle is a one on one affair, will devolve into the same mentality. F35 has serious flaws but amazing tech which make up for some of the shortcomings. Remember though that ruskies have a fully developed network centric warfare model and at the point where you are comparing 250/300km to 400km it becomes pretty much a moot point.

Russians are kinda comparing this to the f35 but it is totally different. It is truly a lightweight stealth fighter. The f35 is certainly not that.

And another game of looking at the intakes begins..

I wonder how much duct work is between the intake and the engine face

The Fail-35 is a fundamentally flawed aircraft, and was so from the initial concept. All the wonderwaffe tech stuff and grossly exaggerated hyperbole about its "superiority" won't fix the underlying issues, and is simply attempt to paper over the cracks and boost its PR appeal to the mouth-breathing mob and foreign purchasers (ie decision makers of the vassal states).

Whatever the final specs are for this new Sukhoi proposal, you can accept at face value that they will get the actual aircraft correct for the intended missions. The question then is simply what jewellery gets fitted...

Meet ‘Checkmate’, Sukhoi’s Sleek New Fifth-Gen Fighter Jet for Half the Cost of an F-35, by Morgan Artyukhina for Sputniknews, 20.07.2021.

On Tuesday, Russia’s Sukhoi aircraft design bureau unveiled a sleek new fighter jet intended to rival Lockheed Martin’s F-35 Joint Strike Fighter. Based on technology from its Su-57 fighter, Sukhoi has dubbed the new fighter “Checkmate.”

A prototype of the Checkmate fighter was the opening act for the MAKS-2021 air show at Zhukovsky Airport southeast of Moscow, which runs from July 20-25 and of which Sputnik is the official media partner. Russian President Vladimir Putin visited the exhibit on its opening day.

The Checkmate is intended for export, and the promotional video released a day before the expo included interested figures from the United Arab Emirates, India, Vietnam, and Argentina.

“It will indeed be oriented towards African countries, India and Vietnam. The demand for these aircraft is quite high, it is estimated at least 300 aircraft in the near future,” Russian Deputy Prime Minister Yuri Borisov said at the presentation on Tuesday. Sukhoi expects to begin deliveries in under six years.

Also at the presentation, Rostec chief Sergei Chemezov said the Checkmate would cost roughly $25-30 million each, which is just a fraction of the price of some advanced European fighter jets like the Dassault Rafale and Saab Gripen, to say nothing of Lockheed’s F-35.

"Why were we able to make this aircraft so quickly? We used the Su-57 developments,” Chemezov explained, noting that among these were the jet’s single engine and its avionics systems.

The jet clearly draws on the Su-57, Russia’s first fifth-generation fighter, in other ways as well, including the slide-back bubble canopy and its internal weapons bay - a standard for minimizing visibility on enemy radars. A display near the jet suggests some of its prospective weaponry, including the R-73 heat-seeking anti-air missile, the R-77 active radar-homing anti-air missile, and the Kh-59MK anti-ship cruise missile, meaning it could be used for both air superiority and surface strike missions.

The Checkmate will also be able to deploy missile-shaped drones from its internal weapons bay, according to the presentation. The fighter will be able to reach speeds of up to Mach 2.2 and an altitude of 54,000 feet.

As a fifth-generation aircraft, the Checkmate will have greatly reduced radar visibility, vectored thrust capability or "supermaneuverability," and likely also supercruise, meaning it would be able to hit supersonic speeds without needing to use the gas-guzzling afterburner.

Notable differences from the Su-57 include its single engine, which will make the Checkmate much lighter but also unable to recover from a burnout; the single diverterless supersonic inlet mounted under the nose; and the four angled tail surfaces, which give it a profile evocative of the failed YF-23 Black Widow, a competitor design to the aircraft that the Pentagon later adopted as the F-22.

Russia hasn't debuted a single-engine fighter aircraft in more than 50 years, since the Su-22 and MiG-27 both entered service in 1970.

Its name, Checkmate, is notably left untranslated from English even in Russian, where the winning move of a game of chess is called “shakh-i-mat.” That leaves little doubt about who the recipient of the message is.

While the US has refused to sell its advanced F-22 Raptor fighter to other nations, the jet’s sister aircraft, the F-35, has been marketed to several, including many NATO allies but also US partners like Israel and the United Arab Emirates. Thus, Checkmate is Moscow’s winning reply to the proliferation of F-35s around the globe.

However, Washington has attempted to frustrate sales of advanced Russian military hardware to other nations through punitive measures such as the Countering America's Adversaries Through Sanctions Act (CAATSA), which the US uses to impose sanctions on the equipment’s buyers. Targeted systems include the Su-35 fighter and S-400 air defense system.

^ The F-35 was a wonder project for a hyperpower. If Russia won the cold war and could print money , it might have ended up the same way.

The su 75 is built in the real world for the real world.

The breakthrough here is that you're getting a mini Su-57 at 25 million dollars. This thing
literally costs as much as about 3 french leclerc.

This has been developed by OAK at its own risk. In principle, VKS is not mixed in this matter, it and it is export oriented.

Russia has an industrial-military strategy of saturating the market with a panoply of weapons systems that can be adjusted to the maximum to all types of customers, unlike the "swallow that" that the F-35 represents for US vassals and extortion for the American taxpayer itself

I doubt very much that the VKS is interested in single engine fighters after so many decades, they are not effective in the Eurasian scenario.
They will continue to buy Su-57 beyond the 76 already ordered

Let's wait to see, for now this model presented today does not fly, maybe MiG also brings out a competing 5th generation single-engine. Especially taking into account the need for a STOVL aircraft for the Navy of Russia and other countries

For the moment Russia Aviation Industri¡y will continue exporting Su-35, Su-30 and should start selling the MiG-35

https://tass.ru/armiya-i-opk/11947075

This is a valid comparison.   The F-35 is range limited and this was an issue in Canada when the replacement for the CF-18s came up.    
The "Su-75" has a roughly 50% greater max range and combat range.

It's not any F-35ski.   The dick strokers need to let go of their members.

It remains to be seen, if it can actually do what the manufacturer says it can do in its propaganda

If you fly faster you need more power and consume more fuel, if you carry more cargo, too, it is not so clear that you can do all that at the same time.
