Cancerman, I worked these programs as well and you are correct in your statements and info regarding B-2, ATA and ATF. I left NGC in the late -90's. I started NGC at ASD-Pico.
Man, you guys are just making me jealous. I would have loved to work at NGC ASD.
I started at ASD-Pico in '86 working to design and build the full-scale flight controls/hydro iron bird test rig (the FCHIL), my first project. By the late '90s when I left NGC, not much going on in the way of new programs, all B-2 went to Palmdale then eventually ASD-Pico closed and was demolished unfortunately.
You and I have crossed paths numerous times. I won't go into too much detail on a public forum, but here's a snapshot, and I won't go into too much detail as some of this I would imagine is still sensitive. In early 1981, I left the USAF, as a weapons system specialist. Main bird was the F111D at CAFB. I went to MD in Long Beach on DC9, MD80, KC10. Being a new hire, I was laid off during contract/union disputes. A friend suggested I go apply at Northrop. I was hired,went through security, since I still had my clearance active from the USAF, they snatched me up at 23 years old. I worked Wind tunnel instrumentation at the Tunnel complex at Aircraft division / Advanced projects. My first program was Tacit Blue which only a hand full of us were cleared for. ATB/B2 was next, along with other "Poverty programs/studies". ATF, and ATA, and some other things. When Pico started it's buildup I was drafted and made the move. When the design was mostly frozen, I was bumped back into my avionics background and took over the Lead tech role in the Avionics lab across the hall from the FCHIL lab. I also integrated the two, allowing the AIL to "Run" the FCHIL bird. I also ran at that time several other "labs" that I won't mention on the forum. Northrop had it's fingers in many areas at Pico. After the 21 bird cut, things were getting tight, the plan was to cut the Lab in two, part going to Palmdale, the other to OK. I was burnt out, and I was building Ultralights and experimental aircraft on the side as a hobby, so I took a voluntary layoff which gave me full benefits while I got my instructors ratings, and went into that field full time. I quickly moved out of CA and set up shop. Been a hell of a ride. I just retired after a 10 year bout with cancer. I'm still standing, just a bit wobbly.
