The term stealth in reference to reduced radar signature aircraft became popular during the late eighties when the Lockheed Martin F-117 stealth fighter became widely known. The first large scale (and public) use of the F-117 was during the Gulf War in 1991.
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
A stealth engineer at Lockheed, Denys Overholser, read Ufimtsev’s publication and realized that he had developed the mathematical theory and tools necessary for finite element analysis of radar reflection. [3] This discovery played a key role in the design of the first true stealth aircraft, the Lockheed F-117.
Lockheed Have Blue was the code name for Lockheed's proof of concept demonstrator for a stealth fighter. Have Blue was designed by Lockheed's Skunk Works division, and tested at Groom Lake, Nevada. The Have Blue was the first fixed-wing aircraft whose external shape was defined by radar engineering rather than by aerospace engineering.
The Northrop Tacit Blue is a technology demonstrator aircraft created to demonstrate that a low-observable stealth surveillance aircraft with a low-probability-of-intercept radar (LPIR) and other sensors could operate close to the forward line of battle with a high degree of survivability.
The other is the fifth-generation J-20 stealth combat aircraft, which was commissioned in 2016. The US has the F-22 Raptor and the F-35 Lightning II in this category of stealth fighter aircraft.
The test flight coincided with the birth anniversary of ... Both have the lack of 90-degree angles typical of stealth shaping for reduced radar detection. ... deployed as many as 250 of the ...
China looks to be building a new radar system purported to have counter-stealth capabilities, analysts found. Satellite images appear to show a SIAR system on Triton Island in the South China Sea.
