As a final curiosity, 1964 also saw an
example of a US airborne SIGINT quid pro
quo for services rendered by Pakistan to
the American intelligence community.
Under the Rivet Flash/Eagle Flight project name, E-Systems modified two Pakistani Martin B-57B tactical bombers to
take an ELINT suite that incorporated
an AN/APR-17 receiver, an AN/ALA-6
direction-finder, a seven-track wideband recorder and an antenna array
that comprised a retractable and steerable AN/ALA-6 assembly and dipoles for

the AN/APR-17. The first Rivet Flash aircraft was delivered during early 1964,
with the second arriving during the following summer. Unfortunately, one of
these aircraft was lost in a friendly fire
incident in 1965.

TODAY
Fast forward 50 years and today's
environment would certainly be recognizable to a 1964 operator. Over time,
airborne SIGINT has had a fairly stable
target set, with varying emphases to

The Model SM6218 Fast Synthesizer, with Frequency Modulation
capability, was developed as an enhancement to our existing
Series SF60 1 usec CW Synthesizer family.
This model generates a wideband modulated signal while locked
to the reference oscillator, thus achieving perfect frequency span
and center frequency. This is in a contrast to common frequency
source solutions where the wideband modulation mode is done in
a "free running" mode and the frequency accuracy is very limited.
The SM6218 offers a higher performance and cost effective
alternative to signal generators currently used in Electronic
Warfare (EW) Simulators and Test Systems and especially those
which require improved frequency accuracy, phase noise and
frequency modulation capabilities.
In addition, the design allows the flexibility to customize
performance to application specific requirements.

* While it is impossible to adequately describe current airborne SIGINT technology in an article of
this size, readers looking for a technology '101'
are directed to Dave Adamy's EW 101 column in
JED together with the magazine's Technology Surveys. Here, Vol 36, Nos 1, 3, 7, 8, 9 and 11 are
particularly useful.

meet the needs of the day. In 1964, the
primary concern was the location and
functionality of air defense networks, a
need that in the recent past has been
superseded by the detection and engagement of hostile insurgents. Here,
COMINT has taken on the role of a sensor-cueing tool with which to prosecute
fleeting and time-critical targets. While
such an approach is extremely effective
against those who are profligate in their
use of radio/cell phone communications,
one wonders what role such a capability
will play in a post-Afghanistan world.
A major change between 1964 and
2014 has been the proliferation of
countries able to field an airborne
SIGINT capability. To those players already mentioned, we can add nations
as diverse as Colombia, Israel, Italy,
Greece, Japan, Saudi Arabia and Turkey.
The spread of the capability also reflects
new usage, with many applications now
directed at homeland security and/or
counter-narcotic targets rather than the
purely military applications that were
to the fore in the mid-1960s. Again, the
airborne SIGINT product base has broadened considerably with, for example,
manufacturers in America, Canada,
France, Germany, Israel, Italy, South Africa, Sweden and the UK all now offering
there wares on the world market.
Perhaps surprisingly, the genre's
technology* has in some ways not
moved forward. Accordingly, current
ELINT technology still makes use of
(for example) superheterodyne and instantaneous frequency measuring receivers, whose functionality was well
understood when the AOC came into
being. What has changed dramatically
is the way in which the technology is
implemented. First and foremost is the
switch from predominantly analog to
predominantly digital systems, which in
combination with solid-state and computing technology has revolutionized
the footprint of applications, the data
they can extract from the environment
