T

he US Navy was becoming increasingly alarmed at the growing trend towards the increasing weight in fighters

Sabre and the Navy’s F9F Panther, and Douglas came up with and attack aircraft of the day, such as the USAF’s F-86

a rather daring proposal for a jet fighter weighing only 7000 pounds, a design which eventually led to the A-4 Skyhawk.

The Navy showed some interest, but since they were already involved in the consideration of several other fighter designs,

they suggested that Douglas should apply the same sort of philosophy to the design of a carrier-based attack aircraft.

This aircraft would be intended for the nuclear strike role, with a top speed of 500mph, a combat radius of 345 miles, a

2000lb weapons load, and a maximum gross weight of less than 30,000 pounds. A Douglas a team led by Ed Heinemann

responded a couple of weeks later with a proposal that exceeded these requirements by a great margin. The normal

loaded weight of the aircraft would be only 12,000lbs, less than half the limit specified by the Navy, and the top speed

was 100mph more and the combat radius 115 miles greater. Douglas was authorised to proceed with further design

studies. During the evaluation, the range requirements were increased, raising the gross weight to 14,000lbs

aircraft with a modified delta planform, with a quarter chord The design team came up with a low-winged jet-powered

sweep of thirty-three degrees. The span was only twenty-seven feet six-inches, which eliminated any need for wing

folding and saving a lot of weight and complexity. The wing had three one-piece spars with span-wise stiffened skin.

The delta shaped wing formed a single box with integral fuel tankage, and the upper and lower skins were single pieces,

and the spars and stringers were continuous from tip to tip. The wing leading edge was equipped with automatic leading

edge slats, and split flaps were provided on the trailing edge. The leading edge slats were designed to drop automatically

at the appropriate speed by gravity and air pressure, thus saving weight and space by omitting actuation motors and
