Such an unknown aircraft. Keep it general since most of what it did is probably still classified.
Buddy of mine flew them in the Fleet as an AW before getting picked up for STA21. General consensus seems to be it’s an example of when you don’t have community advocates in the room where it happens when budget decisions are being made.
Not an ES-3 guy but a former EP-3 guy, the ES-3's were a bit like our little sibling and there was a lot of cross-politization between the platforms, though likely not enough. The ES-3's were still flying and deploying when I first got to the squadron and and I worked with them a few times. They were retired about halfway through my tour and we ended up getting quite a few of the former ES-3 guys in my squadron, pilots and FO's both.
It's just a shitty ES platform... nothing more exciting than that, I'm afraid. I don't recall ever interacting with any ES-3 folks here, but who knows.
It wasn't shitty, it just wasn't utilized very well by the air wings or supported well by big Navy. They had the same automated system that we did on the EP-3 but they actually maintained theirs and did pretty well with it, but it was old by the time it was installed on the ES-3 and wasn't being maintained as a program well. When I did work with them they were sharp enough and did much better than anyone else other than the us and the RC-135 guys, they were just criminally underutilized by the air wings who usually didn't care or bother to learn about their capabilities. They were even using them primarily as tankers on a few air wings.
Why did they get retired so quickly? I think for a few reasons, 1- The Air Wings didn't have an organic SIGINT platform for ~8 years IIRC, from the last time the EA-3's deployed on a carrier in 1987 to I think about 1995 when the ES-3's started and whatever institutional knowledge of the advantages of having an organic SIGINT platform were forgotten, 2 - Lack of training, the aircrew went through the S-3 RAG then got a little SIGINT training on the side but didn't have an opportunity to really learn the discipline more thoroughly, that was directly related to 3- They didn't buy enough aircraft, they're were only 16 and they were constantly deployed and rarely available for training or for exercises at Fallon/Nellis, 4 - Lack of investment, they bought them then didn't do much to update them after that leaving them to quickly become obsolete and 5 - Air Wings didn't seem to know what to do with them or care to learn in most cases.
The biggest reason I think they went away though so quickly though is there was and still is a lack of appreciation in Naval Aviation for what tactical SIGINT can bring to the 'fight'. I worked with several air wings on deployments and they were consistently surprised at some of the things we could do, which were frankly not all that unique or special (though sometimes it was) when it came to SIGINT but no one else was able to do it by that time (Navy-wise) and it was something not utilized that often air wings except in some standard areas and operations, but those kinds of operations were the exception to the rule by the time I was flying. Given the right operators and equipment there can be a wealth of info that could be made available to folks in a rapid manner that isn't today, but Big Navy has decided to invest their money elsewhere.
