In
1970, the
AN/ALQ-101 pod was created to counter both the 10cm wave-lenght SA-75M Dvina (SA-2B/F), and the 6cm wave-lenght S-75M Volhov (SA-2E) systems. (one pod against several threats)
The Volhov was expected by the US to pop up in Vietnam. (it never happened)
This pod used TWT (Traveling Wave Tube), capable to cover the 2.6 to 5.2GHz frequency range.
When this system was installed inside of the
F-105G Wild Weasel aircraft, it was called the
AN/ALQ-105.
During this time, the
US NAVY merged the...
-
AN/ALQ-49 G/H band (against the S-75M Volhov)
-
AN/ALQ-51A D..F band (against the SA-75M Dvina)
... systems into the
AN/ALQ-100 angle deception system, available for the (A7A, F4J) planes.
...and the next technological barrier (called
RANRAP) was soon to be fallen.
