According to the American portal Business Insider*, because of the lack of truly new technologies, the Russian T-50 is a fifth-generation fighter “only on paper”. In particular, it falls behind U.S rivals in stealth, reliability and technical parameters of assemblies and units, the author assures readers.
The U.S. continues to develop a fighter of new generation – F-35 Lightning II, writes Business Insider. Russian specialists are also working on their own version of the aircraft. “Unfortunately for Russia,” notes the edition, “the PAK FA, also known as the T-50, has encountered some manufacturing difficulties, which puts its place in the fifth-generation of fighters in doubt”.
As a result, some aviation experts say that a careful study of the T-50 shows it is a fifth-generation fighter “only on paper”. Basically, the portal claims that this is due to the lack of revolutionary technologies onboard the new aircraft, when compared to previous Russian models. PAK FA uses the same engines as its predecessor – the Su-35. Moreover, both aircraft have largely similar onboard systems, and the different elements are not developed enough for a Russia aircraft fighter of the new generation.
Indian sources familiar with the production of PAK FA claim that the aircraft has many technological problems. Among them,” the operation of the engine, the reliability of radar with active phased array and stealth hardware”.
Meanwhile, according to the publication, the issue of stealth is the most remarkable factor, which gives us an idea about the T-50. In 2010 and 2011, specialists familiar with the Russian development assessed effective surface scattering (EPR) of the plane in the range of 0.3 to 0.5 per square meter.
At the same time, the U.S. air force “hinted”that the EPR of the F-22 is only 0.0001 of a square meter. The indicator for the F-35 is more – 0,001 per square meter, but still “tiny” compared to the PAK FA.
The real values of the EPR of the Russian and American aircraft is classified. “Nevertheless,” says Business Insider, “if preliminary estimates are correct, the PAK FA is significantly inferior in stealth to their American equivalents”.
