OK, without getting into anything classified, I have a question regarding the AN/ALQ-126 ECM system.
Its easy to trace the evolution of USAF ECM pods because they put a version number on them, for example, the AN/ALQ-119(V)-15 is newer and presumably more capable than the AN/ALQ-119(V)-3.
They USN uses internal ECM equipment though and since at least the early 1970s this appears to have come solely in the form of the AN/ALQ-126 and its component systems. I have only been able to ferrit out two versions, the AN/ALQ-126A and B. Can anyone comment on the frequency with which the USN updated the capabilities of these systems, and the degree of improvement that each upgrade brings? For example, the systems in service in 2008 must be more capable than those in service in 1988, even though there is nothing in the designation to indicate a change?
