News from mr Azokhin (KNAAZ):
Т-50-6-2 - Engines tests started, April 10-12 - frequency (controllability) tests with a new version of FCS/FBW software. Maiden flight expected - April the 23-rd.
Т-50-8 - Top coat application, TC finish ETA April the 28-th.
Т-50-9 - Fuselage and lifting body covered with skin panels, undergoes wing planes attachment ETA April the 20-th.
Т-50-10 - Fuselage and lifting body assembled, skin panels application. ETA - unknown.
Т-50-11 - Lifting body assembled. Undergoes fuselage assembly.

MOD and VKS have accepted a "production package" for Т-50 LRIPs - it will have avionics identical to Т-50-9, and airframe identical to Т-50-11.

So, as we can see from the final statement, all the avionics hardware for all the Stage 1 LRIPs will be freezed after T-50-9 and will be the same on T-50-10, T-50-11, T-50-12, T-50 pilot squadron and PMI-1-3.
Airframe for Stage 1 LRIPS including T-50 pilot squadron and PMI-1-3 will be the same as for T-50-11.

We will wait to see them :)

Sukhoi PAK-FA T-50: the latest prototype in final assembly
by Griffon236 · January 26, 2016


Sukhoi PAK-FA T-50, the fifth ...

Sukhoi PAK-FA T-50 has attracted positive comments Bahrain Air Show, King of Bahrain - Hamad bin Isa Al Khalifa - expressing their interest for fifth-generation multi-role aircraft after visiting stands Sukhoi, Rosboronexport and Rosvertol. Export version of the Sukhoi PAK-FA T-50 will enter series production, as planned, in 2020.

T-50, Sukhoi OKB proposal for PAK-FA program (Prospective Airborne Complex - Frontline Aviation) appeared for the first time in public at MAKS 2011 and should enter officially VVS endowment this year.

Series production will start, according to Gen. Bodnarev, Aerospace Force Commander, 2017: "I am hundred percent sure that we will complete the program of state tests this year. The aircraft will enter series production next year. Today is the last prototype, the eleventh is completed at a rate of 60-70 percent, "said Bodnarev after a visit to the plant in Komsomolsk-on-Amur.

Sukhoi PAK-FA T-50 is equipped with advanced avionics and flight systems will become the first fully digital aircraft with stealth technology that goes into equipping VVS.

Sukhoi PAK-FA T-50 is not without problems
Like the Americans, the Russians have about concluded that the development of an aircraft with stealth technology is not just folare ear. The difficulties are financial, economic and technological.

Low observability is not just the alignment angles and bearing surfaces of the fuselage; more needs to be added into the equation and radar-absorbent materials and radio electronic equipment with low emissions. In this regard, the Russians (Soviets) were first installed on airplanes hunting equipment detection and tracking IR, calling the sensors in infrared light and air to air missile with long range for the BVR (maybe because the technological gap towards the West and the inability to develop radar equipment powerful enough).

Russians are about the same level where the Americans were in the 90s with the F 22. After 10 years of development there are only a handful of Sukhoi PAK-FA T-50 in flight status. Still they fail to devise an engine that ensure supercroaziera; more than in June 2014 of cincielea prototype caught fire because of engine ground.

India, Russia to develop patener Sukhoi PAK-FA T-50 is unhappy with the delays accumulated in the development program, as well as increased costs, according to the Business Standard . However, HAL and Sukhoi have reached an agreement on reducing the budget for the PAK-FA T-50 / FGFA 40% from 12 to 8 billion dollars in the period 2016-2023. Cash flow could decrease as a direct result of delays in the development and manufacturing of Sukhoi PAK-FA T-50.

Russians seem to enable increasingly less support program. Western economic sanctions imposed after the annexation of Crimea and involvement in the conflict in Ukraine seriously damaged Russia's budget. The same sanctions have disrupted the flow of Western technology dual-use civil and military, to Moscow. These technologies would be more than useful in developing Russian fifth-generation aircraft. Decline in the price of oil has affected the Russian economy heavily based on resource exports.

All these factors have led to a reduction in the number of Sukhoi T-50 PAK-FA to be purchased by 2020 from 60, many were initially planned, to 12, according to a statement given by Yuri Borisov, adjuct Minister of Defense March 2015.

I think such articles are part of propaganda against Russia. This article gives useless info which is already in public domain, and mixes that with insinuations. The little information is to make the article look genuine.

Any smart person can see the obvious tone of this article.

India's Biggest $25 Billion Defence Deal to Crash Land


NEW DELHI: India has a record of sour defence deals. While the Rafael deal with France to buy 36 fighters jets at nearly `60,000 crore is stuck over a year despite announcement made by PM Narendra Modi during his Paris visit in April 2015, India’s biggest defence buy with its old military hardware partner Russia threatens to crash. It is thrice bigger than the French deal and concerns 127 Fifth Generation Fighter Aircraft (FGFA) costing over $25 billion. `1,500 crore, which India has already paid for preliminary design of the aircraft, may go down the drain. It is the IAF—despite desperation to strengthen its combat fleet—that has put its foot down, citing differences with Russia, the co-developer of the FGFA project.

In an internal communication to the Ministry of Defence, the Air Headquarters has flagged at least 15 objections to the Fifth Generation Fighter Aircraft (FGFA), ranging from fighter’s unreliable engine, poor stealth features, and inadequate radar to its high cost overrun. The letter sent last month has virtually grounded the entire program.

“Under the present scenario, only a political call can revive the program,” a highly placed source said.

In fact, IAF went further to slam Russians for not giving access to the developed prototypes of the aircraft to its pilots. Moreover, it also expressed apprehension that the Russians would not share critical design information with India because they have deliberately reduced the Indian work share despite India’s huge expenditure on the preliminary design. India’s work share in FGFA research and development and other aspects of the multi-billion dollar project at the moment is nearly 10 per cent, even though Delhi is bearing 50 per cent of the project cost.

In 2007, the Congress-led UPA government had signed an inter-governmental agreement with Russia to co-develop the next generation FGFA. It was followed by the $295 million (`1,483 crore) preliminary design contract (PDC) in December 2010. The overall FGFA project cost for making all the 127 fighters in India was pegged at around $25 billion.

The preliminary design stage of the FGFA programme was completed in June 2013 based on a contract signed in December 2010 with the Russian side.

As per the Inter-Governmental Agreement (IGA) signed in October 2007, Hindustan Aeronautics Limited (HAL) is the designated implementation organisation from the Indian side. HAL is supported by agencies, including Defence Research and Development Organisation (DRDO) and Council for Scientific and Industrial Research (CSIR).

The programme requires further $6 billion towards its research and development contract. Defence Minister Manohar Parrikar-led defence acquisition council has to give its approval for the R&D contract. It is believed that the delivery of FGFA to the IAF will begin only after nearly eight years from the start of the R&D contract.

“The ministry is in a dilemma over the future of the program after resistance from the IAF. But simultaneously, the Indian government has already spent a sizeable amount of Rs 1,500 crore on the program. And if the program does not make, spent money might go in waste,” said an official. This deal created controversy during 2011, when a clause was inserted in violation of the defence procurement policy to give contract to Russia to provide International Private Leased Circuit (IPLC) bandwidth connectivity between Bangalore-Moscow-Irkutsk to lay communication lines between the two partners.

IAF’s depleting combat strength has been a cause of concern as it is down to 34 fighter squadrons against 42 of its authorised strength based on certain projections in the next couple of years. IAF is getting four squadrons of Su-30 and subsequently indigenously built Light Combat aircraft Tejas is expected to fill the critical requirement of the force.

Collision Course

■ IAF claims developed engine of FGFA was not reliable

■ Inadequate radar and stealth features

■ Huge cost over-run

■ India’s reduced share. Lack of participation by IAF in the design phase

■ IAF apprehensive that Russia will not share technology

A new engine will be tested in 2018.The present engine allows super cruise and a T/W ratio greater then an fighter in IAF inventory
Inadequate radar and stealth features
The radar is going to be the most powerful in radar to be installed in a fighter .It has 3 X band,2L band and one S band .How many do u want
Well it is more Stealth the Rafale and has better active and passive jammer.It has the best side profile.
India’s reduced share. Lack of participation by IAF in the design phase
What culd have India offered in it .Please tell.
IAF apprehensive that Russia will not share technology
We have already signed a limited ToT deal.

Collision Course

■ IAF claims developed engine of FGFA was not reliable


I do not think IAF is going to buy any FGFA with the existing 117 version. We are looking at the Izdeliye-30 specifically. Even the present engine is far more reliable & has longer HSF and TBO figures than the AL-31 versions IAF currently operates on Su-30MKI.

It can still supercruise and achieve climb rates of upto 384m/s which is the highest among any modern fighter, F-22 included.

"Not reliable" is a vague word and I doubt any serving IAF officer would use such a word.


■ Inadequate radar and stealth features

Another utterly vague term that no-one with an ounce of knowledge about aircraft will make. First of all, what you're seeing right is the prototype T-50 series. It still does not have many of the RCS-reduction features and RAM coatings that the production aircraft will have...and how exactly FGFA might turn out is unknown.

Even then, trying to determine a plane's RCS value or how easy it is for enemy radar computer to recognize just by looking at pictures of it's prototype is something an idiot or internet fanboy would do. It requires professional radar/EM testing and calibration to determine that.

Basically, they're trying to measure the RCS of a plane that does not exist as of know. Pure idiocy. And I'm again sure no serviceman will make such statements unless he has vested interests and/or the mediaperson who uses the term "IAF source" is lying and talking out of his a$$.

And as @Bahamut said, PAK-FA's SH-121 radar complex is the most advanced onboard fire-control radar in development anywhere. No other plane has more arrays, a larger FoV or more advanced TRM architecture.


■ Huge cost over-run

Where???? We recently concluded that the FGFA development will actually cost less than anticipated before.

https://www.rt.com/business/330026-india-russia-fighter-aircraft/

"Negotiators made a breakthrough last month deciding to lower investment cost to $4 billion for each country."

"The 2008 deal is projected to cost each country $6 billion, adjusted for inflation. India’s state-owned Hindustan Aeronautics and Russia’s Sukhoi have agreed to cut costs by 40 percent to $4 billion each over seven years."

This single point proves that this article-writer is shit.


■ India’s reduced share. Lack of participation by IAF in the design phase

I do not think they actually even finished discussions on what all should be incorporated in the Indian version...and this guy already knows exactly what is India's share and if IAF is in the design team or not.

■ IAF apprehensive that Russia will not share technology
First of all, whether Russia shares tech or not is none of IAF's concern. All they care is whether they get their plane or not. Whatever ToT is involved will be absorbed by the local industry, if they feel Russia is not sharing enough, it is they who will complain - not IAF.

Secondly, as long as local production of the Indian version takes place, it means Russia has shared enough ToT already. If anyone is having delusions that "transfer of tech" means that Russia is going to open up all their IPRs to the Indian industry, I'd suggest you guys stop dreaming immediately.

ToT means the transfer of production-engineering knowledge which enables HAL and/or Private companies to successfully build components for the plane and carry out the final assembly here.

Nothing more, nothing less.

Radar/EW codes might be shared for the specific purpose of enabling us to update the onboard threat library as and when we wish with new info and enemy target signature characteristics.

It does not mean we can plagiarize their IPRs and build copies as we like,...we are not China.

This "IAF source" is obviously a phony. The article is written by an American lackey.

Will We Ever Build More F-22s?
Congress wants to restart production of the world’s best stealth fighter, but it’s likely too late
by DAVE MAJUMDAR

The House Armed Services Committee is directing the U.S. Air Force to look at the possibility of restarting production of the stealthy, supersonically cruising Lockheed Martin F-22 Raptor air superiority fighter in its fiscal year 2017 budget. The HASC move comes as a resurgent Russia reasserts itself in Europe and China becomes increasingly aggressive in the Asia-Pacific.

“The committee directs the Secretary of the Air Force to conduct a comprehensive assessment and study of the costs associated with resuming production of F-22 aircraft and provide a report to the congressional defense committees, not later than January 1, 2017, on the findings of this assessment,” reads the bill text.

“In light of growing threats to U.S. air superiority as a result of adversaries closing the technology gap and increasing demand from allies and partners for high- performance, multi-role aircraft to meet evolving and worsening global security threats, the committee believes that such proposals are worthy of further exploration.”



The committee is also directing that the Air Force assess its future air superiority requirements based on its anticipated near-term and mid-term threat projections — from both the air and the ground. The Congress also wants an assessment of how the F-22’s mission is evolving to fight inside anti-access/area-denial environments (A2/AD); when the current fleet will reach the end of their service lives; when the Boeing F-15C will retire; and when a next-generation F-X replacement might become operational.

Additionally, Congress wants an estimate of how much it will cost — and how long it would take — to restart the Raptor production line. The legislative branch also wants cost estimates for the purchase of 194 additional airframes to meet the Air Force’s post-Cold War requirement for 381 Raptors. The service currently has 186 operational Raptors remaining in its inventory — of which only 123 are “combat coded” according to Air Combat Command.

Congress also wants cost estimates for additional jets beyond just having the total number of airframes to fill out 10 fully equipped combat-coded squadrons. It wants to know “the estimated cost of procuring sufficient F-22 aircraft to meet other requirements or inventory levels that the Secretary may deem necessary to support the National Security Strategy and address emerging threats.”

Congress appears to be serious about an F-22 production restart. In the bill language, it asks the Air Force to study other factors that might add to the cost of restarting the Raptor line.

Those include “the availability and suitability of existing F-22A production tooling; the estimated impact on unit and total costs of altering the total buy size and procuring larger and smaller quantities of aircraft; and opportunities for foreign export and partner nation involvement if section 8118 of the Defense Appropriations Act, 1998 (Public Law 105–56) prohibiting export of the F-22 were repealed.”

Indeed, the production tooling could be a serious problem. While Lockheed and the Air Force supposedly made every effort to carefully squirrel away the tooling and instructions for building the F-22, problems have emerged when maintenance crews have attempted to pull the equipment in order to repair damaged jets.


One recently retired Air Force official with direct knowledge about the service’s efforts to repair two damaged Raptors said that they faced severe difficulties with retrieving the correct tooling.

In one example, Air Force maintainers needed to build a particular component from scratch to replace a severely damaged part for an F-22. The crews went into the Conex boxes where the tooling and instructions to build the part were allegedly stored, but to their considerable surprise and aggravation, the container was empty.

The same pattern repeated itself several times — and as of the last time the source checked — the issue has not been completely resolved. The bottom line is that even if the Air Force wanted to, it may not be physically possible to restart the line — at least not without a huge additional investment in time and money.

The second factor to consider is that the Raptor’s avionics were dated even before the jet was declared operational in December 2005. While the Raptor is the most advanced operational warplane in the Air Force’s inventory, its computer architecture dates back to the early 1990s. The core processors run at 25MHz — since it took so long to get the jet from the design phase to production.

Moreover, the Raptor’s software is particularly obtuse and difficult to upgrade — which is partly why integrating the AIM-9X and AIM-120D missiles onto the aircraft has been so problematic.

The jet’s avionics would have to be completely revamped for a production restart, not just because they’re obsolete, but also because the jet’s antique processors and other components haven’t been made in decades. That would be a very expensive proposition.

However — if Congress appropriated enough money — the Air Force could piggyback an F-22 upgrade onto the planned effort to implement an open architecture avionics overhaul on the Lockheed Martin F-35 Joint Strike Fighter in the 2020s. That would allow the Pentagon to take advantage of economies of scale and have commonality between the two types.

Restarting the Raptor production line has come up every so often since then-secretary of defense Robert Gates ordered production of the F-22 shuttered in 2009. Only 187 production model aircraft — or 195 total — were built. That is far short of the original Air Force requirement for 750 jets and about half of the 381 number that Air Combat Command set as a revised requirement in the early 2000s.

But while the Raptor remains the single best-performing fighter ever built, the basic F-22 airframe design originates from the 1980s. Indeed, the Raptor has been in service for more than a decade.

The technology is old — stealth, propulsion, avionics and airframe design have come a long way since the F-22 was designed. If the Air Force were to invest several tens of billions of dollars into an aircraft, it has to ensure that those technologies are still relevant to threats decades from now. By 2035, the Raptor will have been in service for 30 years — without a complete overhaul, most of its systems would be hopelessly obsolete by then.

The reality is that the Air Force likely will probably never restart the Raptor production line. The technology is dated and the jet may not be relevant to the threat environment past the 2030s — especially if one considers that PAK-FA and J-20 are both around the corner. The Air Force has already started laying the groundwork for a next generation air superiority capability it is calling theF-X. We don’t yet know how it will shape up, but it will surely be designed to fight the threats of tomorrow.
