I worked in the Advanced Projects Laboratory in Hawthorne on this project. I designed the Mission Computer Power and Control Console. It worked, as I was told by the operators. Later, I had the job of dismanteling it.

I worked for Northrop in their corporate flight dept. with Don Short. Dick Thomas did most of the experimental test flights on this and has passed away only a few years back. Dick's boss Hank Chouteau, whom I knew, passed away just a few weeks ago as of this writing (5/10/2014)

I started at Northrop in 1980 on this. I thought they had gone crazy when I saw the inboard profile for the first time.

You can find out more about the Garrett ATF3 engines and the five aircraft that it powered by going to my domain at atf3 org .

John C. Evans, 18.07.2012

I worked on the ATF3 engine program from 1968 through 22000. The Tacit Blue had two Garrett ATF3 engines similar to the USCG ATF3-6-2C prototypes. In all five engines were delivered to Northrop with SN's 19101, 19102, 19103, 19104, and 19105. At the completion of the Tacit Blue program the remaining engines were sold to the USCG for spare parts and upgrades to ATF3-6-4C engines.

This now sits in the National Museum of the United States Air Force, at Dayton, Ohio. It looks kind of out of place amongst all the sleeker aircraft around it.

Was the Operations guy for The Whale for it's first two years. What a great time that was. And superb people to work with. Loved it.
