И што мислите,дали САД се поискусни од Русија кога е во прашање СТЕЛТ ТЕХНОЛОГИЈАТА????????
Petr Yakovlevich Ufimtsev (Russian: Пётр ја́ковлевич Уфи́мцев) (born 1931 in Altai Krai) is a Soviet/Russian physicist and mathematician, considered the seminal force behind modern stealth aircraft technology. In the 1960s he began developing equations for predicting the reflection of electromagnetic waves from simple two-dimensional shapes.
Ufimtsev became interested in describing the reflection of lasers while working in Moscow. He gained permission to do work on it after being advised that work was useless and would curtail his advancement. Because the work was considered of no military or economic value, Ufimtsev was allowed to publish his work internationally.[2]
Stealth engineers at Lockheed realized that Ufimtsev had created the tools to do finite analysis of radar reflection.[3] While this discovery inspired, but did not directly have a big role in the Lockheed F-117, Northrop used Ufimtsev's work to program super computers to predict the radar reflection of the B-2 bomber.
In the 1960s he began developing a high-frequency asymptotic theory for predicting the scattering of electromagnetic waves from two-dimensional and three-dimensional objects. Among such objects were the finite size bodies of revolution (disk, finite cylinder with flat bases, finite cone, finite paraboloid, spherical segment, finite thin wire). Now this theory is well known as the Physical Theory of Diffraction (PTD).
The first results of PTD were collected in the book: P.Ya. Ufimtsev, Method of Edge Waves in the Physical Theory of Diffraction, Soviet Radio, Moscow, 1962. In 1971 this book was translated into English with the same title by U.S. Air Force, Foreign Technology Division (National Air Intelligence Center ), Wright-Patterson AFB, OH, 1971. Technical Report AD 733203, Defense Technical Information Center of USA, Cameron Station, Alexandria, VA, 22304-6145, USA.
According to the following publications, this theory played a critical role in the design of American stealth-aircraft F-117 and B-2

2.Не полемизираме дали ф-22 е лош авион или не,но сепак ќе наиде на достоен противник,русите реагираат паметно чекајќи да ги анализираат сите предности и маани па после тоа да го имплементираат во своите авиони
