Before the A4D-2N (A-4C) made its first flight, Douglas and the Navy io gearing up for a major improve­ment in the Skyhawk line. This would be known, initially, as the A4D-5, but all but four would be completed as A-4Es. On 30 July 1959, Douglas was given the go-ahead to produce two A4D-5 aircraft by diverting and modi­fying two A4D-2Ns from the produc­tion line. Besides improved avionics and electronics being installed in the new lengthened nose cone, two major improvements marked the A4D-5. These were a change in pow-erplants and the addition of two new wing hard points, for a total of five.

The new engine was the Pratt & Whitney J52-P-6A which developed 8.500 pounds of thrust, which was an 800 pound increase over the A4D-2N. The J52 had a 27% lower fuel con­sumption rate than the J65-W-16A engine and therefore gave the A4D-5 a substantial increase in range over the A4D-2N. Many A-4Es received 9.300 pound thrust J52-P-8 engines later in their career and were dubbed Super Echos'.

The original Skyhawk had been designed for the nuclear strike mis­sion, but with the addition of the two new pylons a shift to air support and conventional bombing was made. With the five pylons, the maximum weapons load increased to 8,200 pounds.
