Co-production of KG-81 (WALBURN)

HISPEED was the codename of a NATO
evaluation in the mid-1970s, for a
high-speed Trunk Encryption Device (TED).
Philips Usfa contributed to this project by developing
the so-called SATCOLEX crypto device;
an 8 Mb/s line encryptor for multiplexed voice and telex signals.
|
Development took from 1975 to 1977,
but SATCOLEX
was withdrawn right before the actual evaluation,
in return for co-production (for the European market) of the
winning device: the
American WALBURN-based
TED: KG-81
[2].
Philips would build the complete 19" racks and the
KG-81 units for the entire
European market. Several modifications were made especially for NICSMA.
They also received further orders for the design of suitable
interfaces for the device. Development of the additional units lasted from 1979 to 1982, after which production started.

The HISPEED project marked the beginning of a long relationship with the
American NSA.
By the end of 1982, over 95 complete systems had been delivered to NATO.
Each system consisted of a number of
19" racks,
each with several KG-81 units and peripheral devices.
The image above shows a detail of such a
19" rack. Unfortunately, no better quality photographs are available to us
at this time. Some more photographs of the WALBURN racks
can be found below [1].
KG-81
was compatible with the later Philips BVO-T,
that was developed for the Dutch ZODIAC
tactical communications system. It allowed the EUROCOM-compatible ZODIAC
to communicate with NATO data trunks running over KG-81 units.
