Back To Top
The defense industry in the early 1990s was in flux.
Given the new challenges facing the world, defense enterprises knew they either had to grow or be acquired. The Northrop Corporation elected to grow. The first step was to acquire Grumman Corporation in 1994.

Northrop Grumman Legacy Aircraft part of American Advances in Aviation

On July 29, 2005, the U.S. Postal Service issued a set of commemorative postage stamps depicting 10 classic American aircraft from the 1930s, 1940s, and 1950s. Two of the planes listed are legacy Northrop Grumman aircraft: the Grumman F6F Hellcat and the Northrop YB-49 Flying Wing.

F6F Hellcat
The carrier based Grumman F6F Hellcat
YB-49 Flying Wing
The Northrop YB-49 Flying Wing

The carrier-based Grumman F6F Hellcat met with perfection the requirements that had dictated its simple and straightforward design. The robust and maneuverable fighter was easy to mass produce and maintain.

The Northrop YB-49 Flying Wing, a futuristic experimental jet bomber, was designed by Jack Northrop in the late 1940s and was the precursor for the design of the B-2 Stealth Bomber.
