PAK-FA, T-50: News #3

Russian stealth fighter will enhance air force capabilities

In June 2015, I published a short article in the Oxford Analytica Daily Brief discussing the capabilities of new Russian aircraft. Here’s the text, as usual with no edits other than restoring some cuts made for space reasons.

SUBJECT: The Russian T-50 fighter and PAK DA bomber

SIGNIFICANCE: In early June, a series of high profile crashes involving Russian military planes led to Moscow grounding the Tu-95 ‘Bear’ bomber fleet. Additionally, on June 4, a Su-34 strike fighter crashed near Voronezh and a MiG-29 crashed near the Caspian. Military leadership is hoping that the air force’s reliance on old systems will be solved by two new programmes: the Sukhoi T-50 PAK FA and the PAK–DA bomber.

ANALYSIS: Impacts

Russia will continue high frequency of air activity over Baltic and North Sea regions.
Increasing numbers of European air forces will look to procure fifth-generation fighters to maintain approximate parity with Russia.
Shortage of refueling planes will be a concern for the Russian air force and may prove to be an Achilles’ heal.
One of the primary targets of the air force is a stealth fighter, in order to to maintain parity with the United States, a role which is sought for the T-50.

PAK FA T-50

The Russian Air Force has been developing a fifth-generation fighter aircraft since the late 1980s. The PAK FA T-50, has been under development at Sukhoi for about 15 years. The first flight of a prototype aircraft took place in January 2010. A total of five prototype aircraft have been delivered over the last five years. It is expected that the jet will enter service in 2016.

Stealth abilities

This aircraft will be the first operational stealth aircraft operated by Russia. It is expected to be built at least in part out of composite materials, highly manoeuvrable, with supercruise capability and advanced avionics. It will initially use a variant of the Saturn 117 engine currently installed on the Su-35S. A new engine, Product 30, is to be ready for production no earlier than 2017 and will become the standard engine in the 2020s. This engine is supposed to provide 17-18% more thrust, improved fuel efficiency, and higher reliability than the existing engine.

While recently constructed prototypes have been equipped with advanced avionics, reports indicate that the T-50’s electronic components are likely to be upgraded further before serial production begins. The need for continued work on avionic equipment and engines means that the initial production run of the aircraft will retain fourth-generation characteristics and will be comparable to earlier US F-16/18s. The Russian air force will therefore not have a complete fifth-generation fighter until 2020 at the earliest.

F-22 and F-35 comparison

Russia generally compares the T-50 to the F-22, rather than to the F-35. The T-50 has cruising (Mach 1.7) and top (Mach 2.5) speeds that are comparable to the F-22, though it is designed to be significantly faster than the F-35, which has been tested to a top speed of Mach 1.6. The maximum range without refueling is also comparable to the F-22, at 2,000 kilometres, and slightly inferior to the F-35’s 2,200 kilometres. Service ceiling is also relatively comparable, at 20,000 metres for the F-22 and T-50 and over 18,000 metres for the F-35.

There are extensive debates among aviation specialists regarding the relative merits of the three aircraft. These debates are complicated by the lack of reliable information on the characteristics of final versions of various T-50 components, including in such key areas as engines and avionics. At the same time, there is some consensus that the T-50 is more manoeuvrable but less ‘stealthy’ than the F-35 and F-22. Because of this characteristic, the T-50 is expected to be slightly superior to US aircraft in air battles but less successful in attacking ground targets. However, these comparisons are being made based on real data about Western aircraft but only statements regarding the T-50. Given Russian officials’ track record of hiding problems and exaggerating the capabilities of new technology, it is possible, perhaps likely, that the T-50’s performance may not match expectations.

Cooperation with India has stalled

Since 2007, the T-50 project has included a two-seater version designed for the Indian Air Force and commonly known as the FGFA (Fifth Generation Fighter Aircraft). Original plans called for the production of 500 aircraft, with serial production to begin in 2015. Disagreements between the two sides have resulted in serious delays. The Indian side has complained that the aircraft’s engine is underpowered and unreliable, that problems with the airframe reduce the aircraft’s stealth features, that radar and other electronic systems are inadequate, that construction quality is poor, and that as a result of these defects the per unit cost is too high. As a result of these delays, India is expected to receive only three prototypes by 2017.

Procurement plans

Original plans called for the air force to receive 52 T-50 aircraft by 2020 and a total of 250 by 2030. However, officials have announced that due to the deteriorating economy, only twelve of these aircraft will be procured during the next five years. Four planes are expected to be produced during 2015, though these will still be considered prototypes. Therefore, the T-50 will not become a mainstay of the Russian air force in the foreseeable future.

Overall, it is unclear whether the Russian defence industry will be able to produce some of the advanced features on this aircraft, particularly in the areas of stealth technology, avionics and fifth-generation engines. Furthermore, the cost of the aircraft, estimated to be at least 50 million dollars per unit, may make large-scale procurement unaffordable given Russia’s current economic problems.

does not agur well and shows lack of basic understanding about the system.

But if your editor is happy bashing Russia and I understand that sometimes it beyond the writer control then its a good article for Western MSM
