← KY-57 USA ITT Voice Data Saville
The image on the right shows a typical KY-99 unit that was built by
ITT Industries.
The unit measures 140 x 77 x 200 mm and weights approx. 2 kg.
It is a stand-alone unit that needs its own battery (connected at the back).
At the front are three sockets.
At the top are two standard 6-pin U-229 connectors
for AUDIO and DATA respectively.
The DATA connector is also used to connect a standard
key FILL device
such as the KYK-13.
The 13-pin high-density connector for the radio is at the bottom left.
The volume control/power switch is at the center.

The ANDVT-family was launched in the late-1970s
with the introduction of the AN/USC-43 Tactical Terminal (TACTERM).
It was based on the NRLs first successful implementation of the LPC-10
vododer in 1973
[1] and uses
SAVILLE as one of its algoritms.
The KY-99 (MINTERM) is in fact a miniaturized version of the TACTERM.
Its design is based on a modular architecure and, compared to TACTERM,
its size is much reduced.
The KY-99 features full key distribution plus remote key capability
(OTAR) and was certified for secure traffic up to TOP SECRET
(NSA Type 1).
Development of the KY-99 was started in the early 1990s, with the first
training sessions around 1992 [4]. The design was finalized in 1994,
when it was assigned an NSN code.
It replaced the narrow-band KY-65 (2400 bps, HF)
and the wide-band KY-57 (16 kbps, VHF/UHF).
By 2006, over 40,000 ANDVT units were in operation at the US Navy, Air Force,
Army, Allied Forces and US government agencies.
This includes 9363 units that represented a value of US$ 6207 each [2].

The MODE selector is at the bottom right. There are 5 modes of operation:
Plaintext, Ciphertext, Re-key, Off-line and ZEROIZE. Pull the knob to
delete all crypto keys instantly.
The rest of the operation is via
the three push-buttons and the green 8-position alpha-numerical display.

- Low-power
- Lightweight
- Single channel
- Half-duplex
- Narrowband, wideband or wireline
- Secure voice and data (simultaneously)
- Full key distribution
- Over-the-air rekeying (OTAR)
- VINSON (KY-57/58) legacy mode
- Improved SATCOM performance, improved synchronisation
- Improved LPC-10 voice coding algorithm (V58), 2400 baud
- CVSD voice coding, at 12 and 16 kbps (wideband)

The KY-99A is compatible with the other members of the ANDVT-family, such as the
KY-100 (AIRTERM). It is also backward compatible with some legacy products,
such as the KY-57 (VINSON), in which case it uses wideband
CVSD modulation. As far as we currently know, the KY-99 is compatible with:

The HYX-57 wireline adapter allowed two KY-99 units to be interconnected
via a 2- or 4-wire telephone line, up to a distance of 16 km (10 miles).
In case longer distances were required, multiple HYX-57 units could be
cascaded.
