Covert Recorders Nagra
Data logging recorder
- this page is a stub
Crevette (English: shrimp) was a small electromechanical
tape recorder,
developed in 1967 by Nagra
in Switzerland especially for the French Army.
The device was intended for use inside a blank submarine torpedo,
and was used for recording tracking, gyro and navigational data,
allowing engineers to perfect the torpedo's tracking trajectory and guidance
system later [1].

The image on the right shows the Crevette data logger, as it was shown on
the historical pages on the Nagra website in 2018 [1].

The black-and-white image on the right — obtained from an unknown source —
provides a different view of the
recorder, and clearly shows how the two reels are stacked. It also shows
that the larger tape guides are tilted, in order to provide a smooth
transfer from the supply reel at the bottom to the pickup reel at the top.
