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 ...
Plasma stealth is a proposed process to use ionized gas to reduce the radar cross-section (RCS) of an aircraft. Interactions between electromagnetic radiation and ionized gas have been extensively studied for many purposes, including concealing aircraft from radar as stealth technology .
Early stealth aircraft were designed with a focus on minimal radar cross-section (RCS) rather than aerodynamic performance; because of this, the F-117 is aerodynamically unstable in all three aircraft principal axes and requires constant flight corrections from a fly-by-wire (FBW) flight system to maintain controlled flight.
The UAV being deployed to Afghanistan, despite the Taliban having no radar, led to speculation that the aircraft was used to spy on Pakistan or Iran. Phil Finnegan, a UAV analyst at an aerospace consulting firm, suggests the stealth capabilities of the Sentinel are being used to fly in nearby countries.
Stealth may be vital, but so is situational awareness. For sensors, the TAI TF-X is expected to include an indigenous Aselsan AESA-class multimode radar—which can simultaneously scan and jam ...
A stealth ship is a ship that employs stealth technology construction techniques in an effort to make it harder to detect by one or more of radar, visual, sonar, and infrared methods. These techniques borrow from stealth aircraft technology, although some aspects such as wake and acoustic signature reduction ( acoustic quieting ) are unique to ...
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.
