CAM NSA NCR Hagelin
Hagelin C-38 analog · 1944
- this page is a stub
SATYR (codename), also known as AFSAF-102 or CXDA, was an electrical analog
of a Hagelin cipher machine
known variously as
C-38,
CSP-1500
or M-209. It was developed
by the US Navy and was used for enciphering and
deciphering traffic, and for various cryptanalytic processes,
such as testing the settings suggested by HECATE,
WARLOCK I and
other analytic machines [1].
The first SATYR with serial number '1', was built by the
National Cash Register (NCR) in Dayton
(Ohio, US)
in cooperation with the US Navy, and entered service in
late 1944, soon followed by four smaller models.
SATYR is comparable to the US Army's ELECTRICAL HAGELIN ANALOG C-38,
but is somewhat slower as it uses actual
Hagelin pin-wheels
instead of electrical relays [1].

The image above shows an actual SATYR device with a standard input/output
station placed in front of it. At the centre is an electric typewriter of
which the keyboard was used for entering the text. Note the integrated
modified Hagelin cipher machine, just above the typwriter's carriage.
Each machine consists of the following components:
|
- 22 switches with 26-points each, 6 for kick, 15 for overlap and 1 for slide
- Converted set of Hagelin wheels
- Keyboard for input
- 8 x 20 plugboard to make input and output pluggable
|
|
In total, no more than five machines were built.
By 1953, the first machine (with serial number '1') had been dismantled,
but the others remained in service. Three machines were located at the Naval
Security Station in Washington DC, two of which were in Room 20103 where the
HECATE equipment was also located.
The 5th machine was located at USNCML in St. Paul (Minesota, US). 1

USNCML was originally located at the NCR factory in Dayton (Ohio, US),
but was moved to St. Paul (Minesota, US) in 1946, shortly after the new
company Engineering Research Associates (ERA)
had been established there. ERA was founded by former OP-20-G engineers
and incorporated much of the old Naval codebreaking division known as
the Communications Supplementary Activity - Washington (CSAW).
