Yet the Su does appear to be a very low observable design, particularly from the front aspect. Such a reversal is not uncommon in Russian defense practice. Because Russian-olive is most invasive in riparian areas in the western U. Here is the stealth patent and the patent for the air intake, including radar blocker. The Su airframe has aspects that were clear structural choices not to invest heavily in stealth optimization at the cost of other requirements, the T patent filing showed a planned RCS of.
Since key components for the real Su are not yet completed, it is challenging to estimate the actual price per unit. When we think about having low observation qualities or a small radar cross section RCS we are thinking about detection and engagement ranges from a particular type of radar, at a select band, and aspect. The patent filed acknowledges that the core requirements were a contradiction that never happens in acquisition programs! Aircraft design and purpose I think the Su is a misunderstood aircraft in terms of design philosophy, purpose, and program viability. The prototype T was the first to feature a full electronic suite, which will be installed on the serial production model, as opposed to earlier examples that demonstrated partial kit.
