B-57 AN/ANS-7 Navigation Computer

This is a navigation computer used in the RB-57, the C-135, the F-100, and the RF-101.

(Here is a site summarizing the U.S. military equipment designations, such as AN/ANS-7).

The ANS-7 first flew in the late 1950's. It was made by the Ford Instrument Co. (not affiliated with Ford motor companies). At the time Ford was one of the premier manufacturers of electro-mechanical analog computers, including the most impressive monster: the Mark I, which weighed over 3,000 lbs. (More on the Mark I below).

Figure 2 is a closeup of two of the three disk integrators (as described in the intro to this page) contained within the ANS-7.
