Recently I discovered that the Lockheed SR-71 has a built in computer in it. Was it digital or analogue?
I even heard that modern fighters like the Thud had digital computers in them. Is this true?
I know all modern fighter after the F-111 Aardvark had computers like TFR. |

Thud modern? Maybe in 1965...
SR-71 was most certainly an analog computer (no direct knowledge, just based on the time frame) |

You mean the SR's DAFICS (Digital Automatic Flight and Inlet Control System)
The system was originally the AFICS, (no digital part) but the SR as it was retired in the early 1990s DID have digital computers in it.
Ref: http://www.sr-71.org/blackbird/manual/1/1-102.php
3 channels; A, B & M
Other information I found in some of my books and online show that the AFICS manufacturer Honeywell started work on the DAFICS in 1980 and it flew operationally in 1983 replacing the less reliable and slower analog system.
Read: "SR-71 revealed: the inside story" By Rich Graham
The Thud had a navigation computer too, but I believe it was analog from everything I've read.
Keep 'em flyin'
