Given how much of those skillsets is straight up not in manual, just things workers figured out made stuff better over the years of operation... not really.
They already do though. Much of what America makes in military hardware IS sold to allied and occasionally even neutral nations. But like... Something to understand is the sheer absurdity of the SCALE of the US Military, it is literally bigger than every other military on Earth combined last time I checked, China might have managed to make a dent in that, but like, America operates on a scale entirely unique to America in the modern world. The amount of production it would take to keep the military rolling in an actual large conflict is beyond what the entire rest of the nations that make up America's potential market want or need.(note: not talking personnel numbers, talking the things you make with assembly lines)
And like, let's understand something else, the modern understanding of "how life works" is itself underpinned by the American military operating on that scale.
And, further, it is operating on that scale that permits America to just, have the best stuff. As an illustration, you know how the F-16 was plagued by cost overruns and time creep in development and finished massively over budget and crazy expensive? In the time since the F-16 happening and now, the Swedes put together a genuine fifth gen fighter, a peer(at least for what the Swedes want it for), it's development came in under bduget, a key concern was keeping costs down. The per unit cost of the F-16 will be lower than the Swedish Gripen by this time next year. That is not an indication of failure to keep cost down by the Gripen designers, it is an illustration of sheer power of scale.
