In the United States, full-scale tests of the promising F-15QA fighter, intended for the Qatar Air Force, continue. In the foreseeable future, this car will be brought to mass production, as a result of which the Qatari Air Force will become the owners of perhaps the most advanced version of the F-15.

International cooperation

Preliminary agreements on the supply of modernized McDonnell Douglas / Boeing F-15E Strike Eagle aircraft were reached in 2016. In November of the same year, the US authorities approved a deal for the supply of 72 aircraft, spare parts and weapons, as well as personnel training. The estimated cost of such an agreement was to exceed $ 21 billion.

The contract for the construction and supply of equipment appeared in June 2017. In accordance with it, in the coming years, the American side was supposed to create and test a special modification of the original F-15, and then establish its production. The document provides for the supply of 36 fighters with a total value of $ 12 billion.

The United States and Qatar have agreed to create a new modification of the fighter called the F-15QA (Qatar Advanced). The basis for this project was the previous modification of the F-15SA for Saudi Arabia. It was proposed to remake it using the latest developments of the Boeing company and taking into account the wishes of the new customer.

During testing

Design work and construction of experimental equipment did not take long. By the beginning of 2020, the first experienced F-15QA was built and launched for testing. The first flight of this machine took place on April 14. To date, the construction of two more fighters has been completed, they are also involved in the tests.

Reportedly, two prototype aircraft are currently being tested at the Air Force Plant 42 in Palmdale, California. Over the next few weeks, it is planned to carry out a number of different tests that are impossible on other sites. In particular, flight performance at low altitudes is checked, systems for work on ground targets are tested, etc.

During the current tests, the total flight time of the three experienced F-15QA has already exceeded 100 hours. The aircraft have to go through several more stages of verification, after which they will be handed over to the customer. It is expected that the Qatar Air Force will receive this equipment as early as next year. Then a full-scale series will be launched, which will ensure the fulfillment of the existing contract within several years.

Ways of modernization

The F-15QA project envisages updating the design and instrumentation of the basic F-15E / SA, taking into account the wishes of the customer and the latest achievements of science and technology. Such innovations simplify and reduce the cost of assembly and maintenance, as well as increase the flight, combat and operational qualities of the aircraft.

First of all, the airframe production processes have been redesigned. The nose and wing for the F-15QA are made using Boeing's Full-Size Determinant Assembly (FSDA) technology. Within the framework of FSDA, the number of units supplied for final assembly has been reduced, and the process of joining parts is reduced, accelerated and simplified. In addition, some modifications have been made to the design of the units, which increase their resource.

Developing the F-15SA project, the Qatar Air Force fighter receives a similar digital fly-by-wire control system in all channels. It is built on the basis of two computers, each of which has two control loops. Provides a fourfold redundancy of wiring to the actuators. This EDSU architecture provides high flight performance combined with a dramatic increase in reliability.

The F-15QA receives an updated sighting and navigation system based on the Raytheon AN / APG-82 (v) 1 airborne radar with an active phased antenna array. The data processing before being issued to the pilot and navigator-operator is carried out by the ADCP II computer (Advanced Display Core Processor II). The Operational Flight Program operating system is used in the latest “production” version of Suite 8.

The fighter is equipped with a double "glass cockpit". The main means of displaying all the necessary information is a large-format liquid crystal touch screen. On the sides of it are smaller screens. The old windshield indicator has been replaced by a new smaller profile HRCCP (HUD Radio Communications Control Panel) with an integrated radio control panel. Pilots can still use American-made helmet-mounted target designation systems.

Due to the preservation of the main components of the airframe and the power plant, the performance characteristics of the new F-15QA remain at the level of the basic F-15E / SA fighter. The complex of weapons remains the same. Qatar Air Force fighters will be able to use all missiles and bombs compatible with the F-15E.

Another modification

In the recent past, the F-15QA fighter was called the latest and most advanced version of the F-15E. Now this honorary title has passed to the next development. A new aircraft for the US Air Force is being created on the basis of the Qatari fighter. Previously, the F-15X single-seat aircraft project was proposed, but the customer chose the F-15EX two-seat modification, more similar to the F-15QA.

In terms of airframe design and general equipment features, the F-15EX is minimally different from the F-15QA. At the same time, the computing complex will receive the software of the next version of OFP Suite 9, and the survivability will be increased due to the Eagle Passive Active Warning Survivability System (EPAWSS). The ammunition is planned to introduce promising hypersonic air-to-ground missiles and other weapon new types.

On July 13, 2020, the Pentagon officially ordered the first batch of eight F-15EX fighters, costing approx. $ 1,9 billion. By that time, the first aircraft was already being assembled at the Boeing plant in St. Louis. Q2021 FY2023 the first two aircraft must be handed over to the Air Force for testing. The remaining fighters will be handed over only in XNUMX.

In total, the US Air Force wants to buy 144 F-15EX aircraft by 2030. Approx. 22,9 billion dollars. Annually they will order and pay for the construction of 12 vehicles.

Externally, the F-15EX and F-15QA differ only slightly. Boeing graphics

The appearance of an order for the F-15EX is directly related to the state of the air fleet of the Air Force and the National Guard, as well as to the characteristic problems of recent times. Cash F-15C / D are running out of resources and need to be replaced. The number of modern F-22s, initially considered as replacements for the F-15, turned out to be insufficient, and the production of new F-35s does not cover all the needs of the Pentagon. In this regard, a "temporary measure" was adopted in the form of another project for the modernization of the F-15E - with the production of completely new vehicles.

Family perspectives

The development of the F-15 family of fighters continues and produces interesting new results. On the basis of a very successful platform, new modifications are being developed with increased combat and operational characteristics. At the same time, the next versions of the fighter are created not only for the main customer, the US Air Force, but also for friendly foreign countries.

Several factors underlie the F-15's success. First of all, it is necessary to note the high potential of the F-15E aircraft as a platform for further renewal and improvement. Initially, it had good characteristics, and the replacement of certain components ensures further development with obtaining high results. In addition, the problems of newer projects in the form of rising costs and declining production rates became an important factor.

The Saudi, Qatar and US Air Forces have already ordered more than 230 F-15SA / QA / EX fighters. In the foreseeable future, full-scale production will begin, and by the end of the decade, all this equipment will be delivered to parts. Thus, the claimed technical perfection of the new aircraft is gradually turning into commercial success. However, it is too early to talk about the achievement of all the set goals.

One of the unexpected conclusions - if they buy OLD, albeit modernized fighters at 300 million green apiece, 70 million for the F-35 - either a wild lie, or the F-35 is even more junk than they say about it

[OgnennyiKotik]

Of course it's a lie. Below are the actual prices for the F35. In the contracts, the price for the aircraft itself is 40-60% of the total. The F-15EX costs about $ 130-160 million.

[Cowbra]

Quote: OgnennyiKotik

Of course it's a lie. Below are the actual prices for the F35.

But the F-35A that crashed in the US in the spring was estimated at 270 million by the Pentagon. So the "relevance" of these prices is like fair elections in the United States. There, at one site in Michigan, the turnout was under 800%. Here are the prices from there. They have already described how they are formed - a primary contract is concluded, for 70 lam per unit, then a couple of dozen additional ones, and instead of 70, 270 comes out even on the domestic market, why for the USA they buy F-15 for 150 million / unit - this is the internal price

[Dkuznecov]

Here I took the F-35B. $ 101 million.
Its weight is 13 tons.
Let's count in silver.
That's 417960 ounces at $ 24 an ounce.
Total: $ 10.

Yawning. Only arrives from the territory of a neutral state, which does not want to attack Syria. But over Syria or near Turkey, the F-35 ended abruptly.

There was a case, the Lebanese president signed a peace treaty with Israel, but his own Arabs and soaked it, along with the treaty. And in order to cover targets on the border of Syria with Iraq, the Jews had to fly over almost all of Syria, which they did. Nobody noticed anything, and the targets were hit.

Nonsense. Where and when did the F-35 go ​​through state acceptance? The latter lasted from December 2018 to October 2019, the result - on average, 11% of cars were bogotous, mattresses, British, Dutch took part. As a result, the state acceptance failed. as a result, instead of batch orders (FR1-1 ... 1-4), "pre-batch production" LRIP12..14 continues. )
400 with hook models of fighter in pre-production production. Someone robustly warmed his paws ...
The results of the state acceptance at Edwards airbase:

according to reports from the testers of the Joint Office, the average level of full combat readiness of fighters participating in official tests is 11%, and in June - only 8,7% (in the graphs in green). In total, 23 F-35 fighters participate in the acceptance test program at Edwards airbase (the test conditions have already been violated there - some of the aircraft did not correspond to the latest version with updated software). Among the reasons for the low combat readiness is the lack of spare parts and malfunctions of the "distributed" search system - often the radar and electronic warfare systems fail (they catch glitches in the form of false missile launches), the helmet (400 thousand evergreens) give the pilot a picture with interference ... According to the plan proposed by DOT & E of the Pentagon , the level of combat readiness of the fighters participating in the tests should not be lower than 80% (this level of combat readiness Mattis demanded by September for all air forces). It's funny that the level of combat readiness of conventional combatant F-35 is still higher - as much as 23%.

Where and when did the F-35 undergo state acceptance?

There is no state acceptance in the USA.

Can you give a link about an estimate of 270 million?
Is this one of the first F-35s?

[Cowbra]

https://afirsov.livejournal.com/589580.html
https://afirsov.livejournal.com/583777.html
The sources are named, and this is one of the editors of Aviation and Cosmonautics from Technique and Armament.
Pisi: it turned out 170 kopecks. But everything is one - NOT 70 at all. And this is from the Pentagon, which lowers the price.

[Avior]

The source of the figure I found is the official report.
There is no decryption of what is included in the price, only a number.
The plane was initially expensive, everyone knows that, the price dropped with the release. So when it can and was worth it.
He underwent modernization, maintenance, it is quite possible that this was included here.
But this happens with all aircraft.
This has nothing to do with the selling price.
About the understated price - no decoding of what is included, and the devil is in the details.

[Cowbra]

170 instead of 70 is a 2,5 times lower price, not parts. And there is also an interesting schedule from the Americans - the announced and real price for the F-35, and this is already a criminal article of fraud. not details

[Avior]

The schedule is empty there. It is unknown who compiled and what includes
From your link --- this. Just the tabloid press with banged statements.
I found the original report with a figure, there is also no transcript, as it was believed.
The first f-35s in production cost more than 200 million, no one hides this, it is emphasized everywhere that as the production progresses, the price decreases.
And you are trying to compare the aircraft of the old issue with the aircraft of the latest batches. Of course, it used to be more expensive, it is getting cheaper with each batch, there someone brought a plate above.
As for the "real" price, you need to justify where the numbers are from and what is included, not empty pictures.
The contract price can exceed the price of the aircraft several times, this is the most common practice for aviation, and without decoding these numbers, data on the "cost" is an empty phrase.

[EvilLion]

If you bought an aircraft for 170 million, and now it costs 70 million, does this mean that in case of loss, you will lose 170 million? After all, the full replacement of this loss now costs only 70.

[Avior]

We don't know what the 175 million figure includes.
The report contains not the slightest decoding, just a figure in the preface in one short sentence.

... The MA, valued at $ 175,983,949, rolled, caught fire, and was completely destroyed.

Here is a link on how to download the report in PDF.
https://www.defenseworld.net/news/28021/USAF_F_35A_Jet_May_Crash_Caused_By_Technical_Glitch#.X8idMKhwk0M
Therefore, we cannot say what it means.
Maybe this is a figure of how much was spent on this particular board during the operation. Or maybe the cost of a particular board at the time of its purchase.
Early series aircraft were much more expensive, so this cannot be ruled out.
Nothing can be said for sure.
If someone finds how the figure was taken, it will be interesting to read.

[Cowbra]

The word "damage" means lost. Fuel costs are not damage, these words are spelled "OPERATING EXPENSES". And do not include the stupid one, as it was said in the movie "Zhmurki". Otherwise, it is possible even to fairy tales that 176 million is including R&D

[Avior]

Nobody knows what this means in a particular case. And guesses are guesses, some are worth the other.
And the plane of old issues could well cost much more expensive than modern ones.
So you don't need to include what you wrote.

[Cowbra]

Yes Yes. And a combat fighter means - skilful hands that did not pass state acceptance. Nobody knows this either? And stealth means - the newspaper printed that he is invisible, I swear by my mother, they say ...

[DAQ]

One of the unexpected conclusions - if they buy OLD, albeit modernized fighters at 300 million green apiece, 70 million for the F-35 - either a wild lie, or the F-35 is even more junk than they say about it

Firstly, the f-35 will not be sold to just anyone.
Secondly, do not confuse export prices with producer prices.
Plus, you take into account ammunition, spare parts and accessories, training of pilots and those personnel (and possibly maintenance of American technicians), possibly simulators, infrastructure goodies and other related equipment.
Foreign military sales program, the Pentagon buys from the manufacturer and resells to others at 1.5-2 times more expensive.

[d4rkmesa]

The F-35 is not a replacement for the F-15, it is a replacement for the F-16.
The Americans did not rush to full-scale production of the f-22 to replace the f-15.
We made a small batch, since at that time the enemy for the f-22 was not even outlined, and now, thanks to the high modernization potential, the f-15 will stretch until a new aircraft appears, which is now being developed, which will replace the f-15 and f-22 as release.
The super Hornet remains unnoticed for now, let's see what will be replaced, perhaps the same new aircraft.

We launched the F / A-XX program to replace the F / A-18E / F. Ready for the 30th year. Takeoff weight 40 tons, two XA100 / 101 engines if not ready then F135, avionics partially from F35, initially unmanned and manned.

[Avior]

Let's see what will result
40 tons is also suitable for replacing the F-15 and F-22.

Yeah. I think they will make close cars. Like F35A / C

[Avior]

Tom Cat was 34 thousand maximum, superhornet - 30 tons
But if the catapults close, and the engines help, there may be more deck
Actually, a complete analogy with land

[OgnennyiKotik]

A new electromagnetic catapult is being created. It can be used to launch aircraft with a maximum takeoff weight of 45 tons.

[Avior]

Especially. The deck, I think, will survive.
But the hangar, lifts, the finish line - on new aircraft carriers should be provided.

How many Su-35s?

[Dmitry Makarov]

The United States wants to))) purchase 144 units of F-15 until 2030 !!!
Russia already has more than a hundred Su-35s, I think they will still be riveted by 2030.

[Zaurbek]

Well, the United States is at the conclusion of F15 and it is necessary to replace them with something. F35 is already more than 100. And 200 F22. And simple ones with modernization by the F15 and F15E shaft. I am silent about F16.

[EvilLion]

F-22s produced fewer than 200. Since then they have fought.

[EvilLion]

The last 3 Su-35s of the second contract have just handed over, a total of 98 production vehicles, one seems to have been rigidly planted, since it was handed over as a full-scale stand, plus 3 flight prototypes, one of which immediately became non-flying due to a breakdown of 100 % cars. The remaining 2 sides, 901 and 902, have not glowed for a long time, 902 was last lit when the aiming container was tested on it, but, in general, they should already be badly worn out.

The third contract, apparently, 3 aircraft until 30, and then, it seems, the release of capacity for the Su-2024.

[Avior]

So, after 2024, the production of the Su-35 will not be possible, is it?

... The third contract, apparently, 3 aircraft until 30, and then, it seems, the release of capacity for the Su-2024.

[EvilLion]

About the same. What the hell, thousands, if the contract for the F-15EX includes 144 vehicles until 2030. Even if the production of the Su-35 is limited to 3 contracts for the Russian Air Force for 48, 50 and 30 aircraft, as well as exports to China (24 units) and Egypt (apparently, 30 units), this gives 182 copies.

[Zaurbek]

Only, it is desirable that the Su35S has already been upgraded - Radar, Brains, cockpit. In the image and likeness of Su57. And do it in 1 and 2 local versions.

[Reserve buildbat]

I am delighted with the difference in price. For Qatar: "The document provides for the supply of 36 fighters with a total cost of $ 12 billion."
For myself: "In total, the US Air Force wants to purchase 144 F-15EX aircraft by 2030. Approximately 22,9 billion dollars are going to be spent on this equipment."

[Avior]

No wonder
This is not the price of an airplane, but a delivery kit
Fighters are usually purchased with spare parts, long-term armament, spare engines, training for pilots and personnel, often with prepaid service and much more.
The contract price can be several times higher than the cost of the aircraft
It's just that the Americans do not need it, they have it according to other articles.

There is information about its modernization. Which is already good. True, the modernization is flawed and does not reach the possibilities that already exist, but at least so, than not at all.

[EvilLion]

Do you even know what the Su-30SM is? Apparently not, since something surprises you. And it is like a quick adaptation of the Su-30MKI with the preservation of some of the imported equipment, which made it possible to minimize the test time and put it into production in less than 2 years after the first flight. Work on its unification with the Su-1SM began at the same time, in aviation everything is strict, any replacement must be tested.

[Zaurbek]

Ideally, the newest glider, avionics, radar and turbojet engines of all T-10s are from the Su35. And, theoretically, it needs a two-local version. Su30 is the previous generation, and Su34 is the one before last and specialized.

[Object.F7]

The Su-34 is a bomber where fighter functions are a bonus. It was created to replace the Su-24 bomber, how did you drag the Su-35 here, the big question. And why spend money and resources on the development of a two-seater 35th, which "you urgently need", when the modernized two-seater 30th will receive the same engines and part of the Brao 35? Everything in this line is logical and correct. With all the desire and imagination, the F-15 will not be able to become a better bomber than the Su-34, because there is no armored cockpit and the pilots do not sit shoulder to shoulder, as bomber pilots have been positioned since the days of the B-17

[Zaurbek]

I will tell you a secret that all over the world, aircraft of the F15EX type completely replace the Su34 ........ and the F16 variations on the same theme are replaced in light weight

[Object.F7]

Yeah, in July the US government ordered only 8 F-15ex, the first pair of which will not be ready until 2021. And you have them ALL OVER THE WORLD WILL REPLACE the Su-34 ... In my opinion, you need to share your secrets in one of the clinics

[Zaurbek]

Before that there was an F15E which was not a full-fledged fighter

[Zaurbek]

They wrote that this is thanks to the Hindus and the "Super-Dry" theme. Why not make a 2-seater Su35 right away? It would be more progressive than the old Su30SM glider

[Jacket in stock]

Here are good fellows Boeing, they are already taking envy. Once every five years, a new modification, everything new has appeared, immediately into action.
And here - the SU-35 has been flying for 15 years and no upgrades are expected.
The SU-30 is generally an old man, they guessed to update the current-current at least to the level of the SU-35, well, at least there will be unification at the same time.
You can nod at the SU-57, they say, here it is, progress. Well, its final version did not appear yesterday either.
We brake. : (((

[EvilLion]

How can a Su-35 fly for 15 years when it first flew in 2008? You teach the materiel or something, otherwise you will blow bubbles into a puddle.

[Object.F7]

I'll tell you a big secret, just don't tell anyone, but the Su-30, according to the same principle, may differ in versions for each specific customer. And Migi, too, Algeria was put in the maximum upgrade. This is a completely unique logic, where the Su-30 from the nineties is an old man, and the F-15 is the newest aircraft (in service since 1976)
