I don't see how your questions follow from your premise (companies are entitled to protection, therefore the government can take them over

)
The premise is the idea that the state affords protections to businesses operating within the state. There are certain rights and responsibilities associated with those businesses for the good of the state. Just as citizens have responsibilities in times of war ala selective service, it seems reasonable to contemplate a parallel idea for businesses.

The government cannot nationalize a company, for any reason. I think it is unprecedented in the US. Although the government can "eminent domain" property for the good of the citizenry (often abusing this power), there is no basis for taking over the management of companies.
Yes, so what's the difference between eminent domain and nationalizing? Seems to me eminent domain could be employed here.

I'll go with the "not" side and say that doing so would end up doing more damage to the economy -- by taking money out of investors hands -- than it would help in the medium-term.
It's conceivable that the state could believe there is sufficient reason to nationalize despite the negative economic impact. For example, what if all but a few communications satellites remained functional after some attack (physical or viral)? Could the military take over the NBC satellite to aid in communications?
...and as to precedence...

Yes and no. Here's where I finally get to explain. In WWII, much of the steel and food output from this country was directed to the war effort. How did that happen?
The government bought up the supply. And it has the economic power to do that. So why take over a company when it can purchase its entire output for a war effort?
Yes, since the government could "own" steel & food, it did. However, I find it hard to believe that the government could "own" all the silicon whereas it could just decide to "own", say, Intel.
