The F-117 is one of the strangest looking airplanes ever created, but its unique shape makes it almost invisible to radar. It introduced the concept of “stealth technology”.

It is now about to retire:

F-117 Stealth Fighter to Be Retired

From the article:

The Air Force decided to accelerate the retirement of the F-117s to free up funding to modernize the rest of the fleet. The F-117 is being replaced by the F-22 Raptor, which also has stealth technology.

Fifty-nine F-117s were made; 10 were retired in December 2006 and 27 since then, the Air Force said. Seven of the planes have crashed, one in Serbia in 1999.

Stealth technology used on the F-117 was developed in the 1970s to help evade enemy radar. While not invisible to radar, the F-117′s shape and coating greatly reduced its detection.

It will be replaced by the F-22 Raptor
