Lockheed huh?
From '87 through the mid 90's I worked for a company that did loads of castings for Lockheed, Martin-Marietta, ext, ext.
Machine gun parts, Hellfire & cruise missile nose & fin assemblies, tow missile launcher components, ext. We built lots of cool toys of destruction.
We even knew we were making parts for the stealth fighter long before that little crash in the desert made them admit we had it. And when that happened we had already been making parts for the stealth bomber for well over a year.
