2023年7月25日 · Combat experience indicates the F-117's actual RCS to be significantly higher than predicted by a basic physical optics model. In particular, its S-band RCS is likely on the order of -3 dBsm, at best -10.

The Lockheed F-117 Nighthawk is a retired American single-seat, subsonic, twin-engined, stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). It was the first operational …

2024年5月18日 · Additionally, according to an Air Force Magazine July/August 2019 infographic, the F-117 has a radar cross section (RCS) of 0.003m2 square meters, or that of three insects. The F-35A has an RCS slightly more, 0.005m2 square meters.

2017年3月31日 · Our first stealth fighter/bomber was the F-117 Nighthawk from the 1980s. It has an RCS of 0.003m2, about the size of a hummingbird, and those F-117s hit more than 1,600 targets without being molested by Iraqi air defenses during the 1991 Gulf War.

Abstract: World's first true `Stealth' aircraft F-117 Nighthawk Fighter is considered as the target object and its Radar Cross Section (RCS) has been measured in this paper. RCS is an important parameter for radar to detect the target accurately.

2023年11月19日 · The F-117A program demonstrated that stealth aircraft with a low radar cross section (RCS) could be conceived, designed and developed, as the following story that appears in Ben Rich’s Book “Skunk Works” proves.

2022年11月17日 · The F-117A production decision was made in 1978 with a contract awarded to Lockheed Advanced Development Projects, the “Skunk Works,” in Burbank, Calif. The first flight over the Nevada test ranges was on Jun. 18, 1981, only 31 months after the full-scale development decision.

F-117 was an attack bomber, the first operational stealth aircraft in the world. The main feature was its unusual, highly faceted design which accounted for its low observability. The F-117 had an...

2025年2月23日 · Lockheed F-117 Nighthawk. To quantify the visibility of an object on radar the Radar Cross section (RCS) 𝜎 in units of m² is used. It depends on the radar frequency, polarization, location of antenna and the orientation, material and shape of the target object.

2022年1月24日 · In fact, the 65-foot-long, 29,000-pound Nighthawk had a radar cross-section (RCS) of just 0.003 square meters, about the size of a golf-ball. By way of comparison, the similar sized F-15 Eagle ’s RCS is more than 25 square meters.
