At the height of the Cold War, the U.S. Air Force was turning to stealth technology to advance its recon missions against its adversaries further, and the arrival of the F-117 Nighthawk couldn’t be more perfect.

Sneaking Into The Night

The Defense Advanced Research Projects Agency (DARPA) began looking for new technology in the mid-1970s that would emit “little-to-no radio, infrared, or light energy,” allowing its aircraft to slip undetected on enemy radar and enter its airspace. In response to the urgent national need, Lockheed worked on materializing a groundbreaking stealth demonstrator aircraft codename HAVE Blue, also known as “the Hopeless Diamond,” under Skunk Works in 1976. Less than a year later, the HAVE Blue made its maiden flight, successfully soaring across the dark skies of Nevada. This project then led to the conception of the F-117 Nighthawk. DARPA awarded a contract to Lockheed Skunk Works in November 1978, kickstarting the further development of the Nighthawk that would forever change stealth technology.

The F-117 made significant and transformative breakthroughs in stealth technology. First, it broke the rules of aerodynamics through its overall design. Instead of the conventional aircraft appearance, it sported lots of angles—it “had a triangular structure with its wings swept sharply back from the nose at a sixty-seven degrees angle, and a surface composed of many flat planes oriented,” allowing itself to deflect radar waves. At first glance, one might wonder if it could fly. And it surprisingly can.

Conquering The Skies

In June 1981, the F-117 made its first flight within the restricted airspace of Nevada, becoming the first operational stealth fighter. Around this time, the project remained under wraps, so most pilot testing was conducted deep into the night to avoid detection. By 1988, rumors began surfacing after dozens of witnesses reported about a mysterious aircraft-looking being transported, and years prior when two separate crash accidents occurred, one in 1986 and another in 1987, perking the public’s interest. It wasn’t until April 1990 when the F-117s concluded their production and made their first official public appearance at Nellis AFB in Nevada, attended by thousands of curious onlookers. There were 64 Nighthawks built between the secrecy period, 59 of which were production versions, while the remaining five were developmental prototypes.

The Nighthawk only had one functional variant, the F-117A, assigned under the 37th Tactical Fighter Wing (formerly 4450th Tactical Group). Months before its public unveiling, two F-117As were sent to execute their first combat mission during Operation Just Cause on December 19, 1989, sneakily attacking military targets in Panama. That same year, the F-117A received one of the most prized aeronautical awards, the Collier Trophy.

However, what cemented the legacy of the F-117 was its significant participation in the Gulf War of 1991. Accordingly, dozens of “F-117As flew 1,271 sorties, achieving an 80 percent mission success rate, and suffered no losses or battle damage.”

It also fought in the Kosovo conflict, losing one aircraft, throughout the 1990s and the Iraq War in the early 2000s. But, the Nighthawk all but vanished just as quickly as it appeared. And by 2008, the sophisticated, game-changing stealth fighter was permanently grounded, ending a relatively short aviation career of 27 years. What gives?

The Early Retirement of F-117

At first, it may seem perplexing why the F-117 Nighthawk retired, barely reaching its 30th year since development. That despite being heralded as a state-of-the-art stealth fighter, the Nighthawk didn’t reign the skies for longer than it may have. Well, for the same reason that plagued outstanding aircraft before her—the rise of more powerful and capable platforms.

The same revolutionary design, the “breaking the rules of aerodynamics” specifications, of the F-117 Nighthawk also caused its descent. The aircraft became unstable in its roll, pitch, and yaw axes. It also frequently suffered from “wing failure” problems, among other airframe design flaws. In addition, engineers had to sacrifice outfitting high-end technology because they had to limit the radar emission of the F-117. Not to mention that the stealth aircraft can only be armed with at least four bombs weighing not more than 5,000 lbs. No guns.

The stealth technology was undeniably impressive, but that was it. These limitations would ultimately hold the Nighthawk to further its long-term effectiveness, leading to its final touchdown.

Nevertheless, the F-117 Nighthawk’s legacy lives on through the stealth bomber B-2 Spirit, the stealth tactical fighter F-22 Raptor, and the new generation stealth fighter F-35 Lightning II.

The F-117 Nighthawk had a special flyover ceremony at Holloman Air Force Base during its retirement in April 2008. Today, the stealth fighter’s second prototype can be found on display at the National Museum of the U.S. Air Force in Dayton, Ohio.
