US Air Force pilots flying the F-117 Nighthawk Stealth jets approached Luminox to make watches specifically for them. Luminox created the original F-117 watch 3400 series in a 43mm black PVD plated stainless steel case. The case has a detailed engraving of the F-117 Nighthawk Stealth jet, for which Luminox has a proprietary worldwide watch license with Lockheed Martin. A second version of this series, the 6400 series, also as black as the night, was created with a larger, bolder, more angular design to evoke the flavor of the jet itself. It strikes a stronger profile in a 45 mm stainless steel case

F-117 Nighthawk Stealth Fighter

F-117 Nighthawk Stealth Fighter

The F-117 Nighthawk stealth fighter, developed in total secrecy, was the first operational platform to employ what is known today as “stealth.” Its startling, unconventional shape clearly signified the arrival of a new era in fighter performance through low-observable technology.

Operation Desert Storm first saw the potential of an aircraft that could penetrate dense threat environments at night. Comprising 2 to 3 percent of coalition forces, the F-117 accounted for 30 to 35 percent of first-night targets and hit rates of 75 percent in Desert Storm to over 90 percent in Operation Allied Force. The F-117 also sustained the highest mission-capability rates of any deployed fighter or bomber in both conflicts, exceeding 82 percent.

While the USAF retired the F-117 on 22 April 2008 it continues to symbolize the innovative thinking of Lockheed Martin’s Skunk Works®
