Russia’s new SU T-50 fifth generation fighter gets new engine and new name

Certain Russian publications have in recent weeks begun referring to Russia’s new fifth generation fighter – hitherto known as the “SU T50” (a designation designating a test aircraft) – as “SU-57”, suggesting that this may be the aircraft’s name when it enters service with the Russian Aerospace Forces.

This has not so far been definitely confirmed.  Moreover the name has a much higher number – “57” – than might have been expected.

Russian fighter jets are given numbers depending on their place in the sequence of aircraft designed by a design bureau that enter service.  Thus the “SU-7” of the 1950s is obviously an older aircraft than the “SU-27” of the 1980s, with the difference in the numbers indicating the number of designs the bureau – in this instance the Sukhoi bureau – has developed between the two aircraft.

This is not a rigid rule, and it is complicated by the fact that the Russians tend to use odd numbers for fighter aircraft with a crew of one and even numbers for aircraft with a crew of more than one, though this is not a rigid rule either.

As it happens we know that between the entry of the SU-7 into service in the 1950s and the appearance of the SU-27 in the 1980s the Sukhoi bureau designed and brought into service the following aircraft: SU-9, SU-11, SU-15, SU-17, SU-20, SU-22, SU-24 and SU-25.

The surprisingly large difference in the number used for the last Sukhoi fighter jet to enter service – SU-35 – and that allegedly used by the final version of the SU T50 – SU-57 – may indicate the great number of failed and abortive projects in which the Sukhoi bureau was involved during the crisis years of the 1990s and early 2000s, only some of which are known about.  However the reported name – “SU-57” – could be wrong, or – more plausibly – it might be an unofficial name used by the Sukhoi bureau, in which case the name the aircraft will eventually be given by the Russian Aerospace Forces might be completely different.

In view of this uncertainty I will stick to using the SU T50 designation for the time being.

What is beyond doubt is that the SU T50 is now about to start testing with its new engine, which is in fact its definitive engine which has been specifically designed for it.

There is very little information about this engine, with the Russians not even disclosing its proper name (the Russians refer to it in open publications as “item 30”).

What is however known about this new engine is that it is entirely new, that is the first completely new engine for a fighter jet designed in Russia since the USSR’s fall, that it has been developed by the Saturn Engine Design Bureau in Rybinsk (the design bureau responsible for all engines used by Sukhoi fighter jets since the 1950s) and that it is significantly more powerful than the AL-41F1 engine the SU T50 has been flying with up to now.

The AL-41F1 is in fact an advanced derivative of the AL-31 engine developed in the 1970s for the SU-27 fighter.  The SU T50 has up to now being flying with this engine because in a break with traditional Russian practice the Russians initiated development of the SU T50 some years before the new “item 30” engine was ready.

The new “item 30” engine is said to be far more powerful and far more efficient than the AL-41F1, as is to be expected of a wholly new engine having no connection to the AL-31/AL-41 family of engines which have their roots in the 1970s.

The best indication of how much more powerful and efficient the new engine is has been provided in a detailed description of the SU T50 provided by the official Russian news agency TASS.

This puts the thrust ratings of the AL-41F1 at 8,800 kgf and at 14,500 kgf when using an afterburner. By contrast the thrust ratings of the new “item 30” engine are put at 11,000 kfg and at 18,000 kgf when using an afterburner.

This is a very significant increase in thrust.  It is likely that the new engine is also significantly lighter and more fuel efficient than the older AL-41F1.

Apparently the SU T50 is already capable of supersonic flight with its current AL-41F1 engines even when they are being used without afterburner – what is known as “supercruise”.   Obviously the flight performance of the SU T50 will increase very considerably once it is powered by the new engine.

Recently there has been uncertainty as to the precise date when the SU T50 will enter service.

There are reports that on 23rd March 2015 Russian Deputy Defence Minister Yury Borisov visited the factory in Komsomolsk-on-Amur in Russia’s Far East where Sukhoi fighters are built and told the workforce that the Russian Aerospace Forces would delay entry of the SU T50 into service because the highly effective SU-35 and SU-30 fighters already in service and being built at the factory offered a more cost effective solution to their current needs.

Borisov is supposed to have said that the Russian Aerospace Forces would initially only buy one squadron of 12 SU T50 aircraft using the current AL-41F1 engine – to be delivered apparently next year ie. in 2018 – and would instead buy more SU-35s and SU-30s, with total orders for the SU-35 and the SU-30 being put at 98 aircraft and 116 aircraft respectively.

Full service entry of the SU T50, and large orders for the aircraft, would in the meantime be delayed until the “item 30” engine is ready, with all SU T50 aircraft entering front line service with the Russian Aerospace Forces using only this engine.

This makes sense.  It should not be seen so much as an economy measure – as most commentators suppose – but rather as a response to the earlier than expected availability of the “item 30” engine, whose development seems to have gone smoother and faster than expected.

Given the availability of the new engine and the dramatic improvement in performance it offers, it makes perfect sense to delay service of the SU T50 until the new engine is fully ready and is being produced in quantity.

In the meantime it also makes sense to build more of the current highly potent and fully perfected SU-35s and SU-30s rather than accept into service an incomplete SU T50 whose performance is compromised by use of the older AL-41F1 engine.

Apparently the plan now is for the SU T50 to begin entering service in quantity with the new engine in 2021 with the initial order being apparently set at 60.  The Aerospace Forces will use the intervening period to familiarise themselves fully with the new aircraft by working out on the test squadron of 12 which will be provided to them next year.

This is consistent with the conservative Russian approach, which in contrast to the US avoids pressing into service new aircraft or weapons systems before they have been fully perfected and all the bugs in them have been ironed out.

This approach is not only effective in performance terms – since it ensures that new aircraft and weapons systems are fully combat capable when they enter service – but has repeatedly been shown to be more cost effective as well.  Suffice to say that many of the US’s recent procurement disasters have been caused by the over hasty entry into service of advanced new weapons systems before their technology has fully matured, and before all the problems connected with them have been ironed out.

In the meantime all comparisons between the US’s F-22 and F-35 fighters and the SU T50 using its current AL-41F1 engines – which is to say nearly all of them – are now valueless since the SU T50 will not enter service with these engines.

A more valid point critics of the SU T50 programme can make is that the Russians are bringing their fifth generation fighter much later into service than the Americans.  Suffice to say that the F-22 Raptor’s entry into service was in 2005, whilst the SU T50 is not now expected to enter service before 2021.

This delay is the direct result of the massive disruption to Russia’s aerospace industry caused by the crisis of the 1990s and early 2000s.  The fact the Russians have only now successfully matched their fifth generation fighter with its definitive “item 30” engine – in stark contrast to their historic practice, which is to develop the engine first – is a reflection of this disruption, which their industry has only now finally overcome.

The one big advantage for the Russians from this delay is that their SU T50 fifth generation fighter will be a significantly more modern aircraft when it enters service than its closest US analogue: the F-22 Raptor.  As a result the SU T50 will be able to benefit from the very considerable advances in technology which have taken place since the first fifth generation fighter – the US’s F-22 Raptor – entered service in 2005.

I will finish with a video of the highly impressive flight display the SU T50 flight put on at the recent MAKS 2017 airshow in Moscow in June this year.  Note that the aircraft is flying with its current AL-41F1 engine.  What sort of flight display it will put on when it is flying with its definitive “item 30” engine one can only imagine

In the meantime the F35 is ruining the economy of Italy and the few other nations that stayed in the (imposed) program ! As the designer of the F16 said, it is a “lemon”, a real failure !
Of course Lockheed had to buy our politicians in the same way they did in the 60s (and were found out) to impose the C130 when we had our own european alternatives !
We are the vassals of the United Snakes of Amerikkka and paying dearly the privilege !

Photos of swastika on Ukrainian mall stairway creates a stir [Video]

Ukrainian nationalist press in damage-control mode to explain away the Nazi sign, but they forgot the name of the street the mall is on.

Seraphim Hanisch

One of the aspects of news about Ukraine that does not make it past the gatekeepers of the American and Western news media is how a significant contingent of Ukrainian nationalists have espoused a sense of reverence for Nazis. The idea that this could even happen anywhere in the world in an open manner makes the claim seem too absurd to be taken seriously. Gone are the days when the Nazi swastika adorned streets and buildings in Europe. Right?

Well, maybe, wrong.

This was seen in Kyiv’s Gorodok (or Horodok, if you insist) Gallery, a shopping center in that city, located on Bandera Avenue.

The pro-nationalist news service UNIAN wasted no time going to press with their explanation of this incident, which admittedly may be accurate:

Children and teenagers who participated in the All-Ukrainian break dance festival held in the Kyiv-based Gorodok Gallery shopping mall were shocked to see a swastika image projected onto an LED staircase.

The mall administration apologized to visitors, explaining saying that their computer system had apparently been hacked.

“The administration and staff have no relation to whatever was projected onto the LED-staircase, and in no way does it support such [an] act. Now we are actively searching for those involved in the attack,” it said in a statement.

According to Gorodok Gallery’s administrative office, it was not the first time a cyber breach took place.

As reported earlier, Ukraine is believed to be a testing ground for cyberattacks, many of which are launched from Russia. Hackers have earlier targeted critical energy infrastructure, state institutions, banks, and large businesses.

This time, it appears, hackers aimed to feed the Kremlin’s narrative of “Nazis in power in Ukraine” and create a relevant hype-driving viral story for Russian media to spread it worldwide.

The Gorodok Gallery also apologized on its Facebook page and said that this was a result of hacking.

But what about the street that the mall is on? From the self-same Facebook page, this is what we see:


To translate, for those who do not read Ukrainian or Russian, the address says the following:

23 Steven Bandera Prospekt, Kyiv, Ukraine 04073

This street was formerly called “Moscow Avenue.” Big change, as we shall see.

Steven Bandera got his birthday designated as a national holiday in Ukraine last December. He is known in Ukraine’s history for one thing. According to the Jerusalem Post:

The street where the shopping mall is located is named for Stepan Bandera, a Ukrainian nationalist who briefly collaborated with Nazi Germany in its fight against Russia.

His troops are believed to have killed thousands of Jews.

Several Israeli papers picked this bit of news up, and of course, the reasons are understandable. However, for the West, it appears possible that this news event will largely go unnoticed, even by that great nation that is often called “Israel’s proxy”, the United States.

This is probably because for certain people in the US, there is a sense of desperation to mask the nature of events that are happening in Ukraine.

The usual fare of mainstream news for the West probably consists of things like “Putin’s military seizes innocent Ukrainian sailors in Kerch incident” or, “Ukraine’s Orthodox Church declared fully independent by Patriarch of Constantinople” (not that too many Americans know what a Constantinople even is, anyway), but the overriding narrative for the American people about this country is “Ukraine are the good guys, and Russia are the bad guys,” and this will not be pushed aside, even to accommodate the logical grievance of Israel to this incident.

If this article gets to Western papers at all, it will be the UNIAN line they adhere to, that evil pro-Russia hackers caused this stairway to have a swastika to provoke the idea that Ukraine somehow supports Naziism.

But UNIAN neglected to mention that the street name was recently changed to Stephan Bandera (in 2016), and no one appears to have hacked this. Nor does UNIAN talk about the Azov fighters that openly espoused much of the Nazi ideology. For nationalist Ukrainians, this is all for the greater good of getting rid of all things Russia.

A further sad fact about this is the near impossibility of getting assuredly honest and neutral information about this and other similar happenings. Both Ukrainian nationalists and Russian media agencies have dogs in the race, so to speak. They are both personally connected to these events. However, the Russian media cannot be discounted here, because they do offer a witness and perspective, probably the closest to any objective look at what is going on in Ukraine. We include a video of a “torchlight march” that took place in 2017 that featured such hypernationalist activity, which is not reported in the West.

More such reports are available, but this one seemed the best one to summarize the character of what is going on in the country.

While we do not know the motive and identities of whoever programmed the swastika, it cannot really be stated that this was just a random publicity stunt in a country that has no relationship with Nazi veneration.

The street the mall is on bears witness to that.

Putin: If mid-range missiles deployed in Europe, Russia will station arms to strike decision centers

Putin: If US deploys mid-range missiles in Europe, Russia will be forced to respond.

RT

Published

Via RT…


If the US deploys intermediate-range missiles in Europe, Moscow will respond by stationing weapons aimed not only against missiles themselves, but also at command and control centers, from which a launch order would come.

The warning came from President Vladimir Putin, who announced Russia’s planned actions after the US withdraws from the INF Treaty – a Cold War-era agreement between Washington and Moscow which banned both sides form having ground-based cruise and ballistic missiles and developing relevant technology.

The US is set to unilaterally withdraw from the treaty in six months, which opens the possibility of once again deploying these missiles in Europe. Russia would see that as a major threat and respond with its own deployments, Putin said.

Intermediate-range missiles were banned and removed from Europe because they would leave a very short window of opportunity for the other side to decide whether to fire in retaliation after detecting a launch – mere minutes. This poses the threat of an accidental nuclear exchange triggered by a false launch warning, with the officer in charge having no time to double check.

“Russia will be forced to create and deploy weapon systems, which can be used not only against the territories from which this direct threat would be projected, but also against those territories where decision centers are located, from which an order to use those weapons against us may come.” The Russian president, who was delivering a keynote address to the Russian parliament on Wednesday, did not elaborate on whether any counter-deployment would only target US command-and-control sites in Europe or would also include targets on American soil.

He did say the Russian weapon system in terms of flight times and other specifications would “correspond” to those targeting Russia.

“We know how to do it and we will implement those plans without a delay once the relevant threats against us materialize,”he said.

Russia’s Lukoil Halts Oil Swaps In Venezuela After U.S. Sanctions

Under the new wide-ranging U.S. sanctions, Venezuela will not be able to import U.S. naphtha which it has typically used to dilute its heavy crude grades.

Litasco, the international trading arm of Russia’s second-biggest oil producer Lukoil, stopped its oil swaps deals with Venezuela immediately after the U.S. imposed sanctions on Venezuela’s oil industry and state oil firm PDVSA, Lukoil’s chief executive Vagit Alekperov said at an investment forum in Russia.

Russia, which stands by Nicolas Maduro in the ongoing Venezuelan political crisis, has vowed to defend its interests in Venezuela—including oil interests—within the international law using “all mechanisms available to us.”

Because of Moscow’s support for Maduro, the international community and market analysts are closely watching the relationship of Russian oil companies with Venezuela.

“Litasco does not work with Venezuela. Before the restrictions were imposed, Litasco had operations to deliver oil products and to sell oil. There were swap operations. Today there are none, since the sanctions were imposed,” Lukoil’s Alekperov said at the Russian Investment Forum in the Black Sea resort of Sochi.

Another Russian oil producer, Gazprom Neft, however, does not see major risks for its oil business in Venezuela, the company’s chief executive officer Alexander Dyukov said at the same event.

Gazprom Neft has not supplied and does not supply oil products to Venezuela needed to dilute the thick heavy Venezuelan oil, Dyukov said, noting that the Latin American country hadn’t approached Gazprom Neft for possible supply of oil products for diluents.

Under the new wide-ranging U.S. sanctions, Venezuela will not be able to import U.S. naphtha which it has typically used to dilute its heavy crude grades. Analysts expect that a shortage of diluents could accelerate beginning this month the already steadily declining Venezuelan oil production and exports.

Venezuela’s crude oil production plunged by another 59,000 bpd from December 2018 to stand at just 1.106 million bpd in January 2019, OPEC’s secondary sources figures showed in the cartel’s closely watched Monthly Oil Market Report (MOMR) this week.
