Does this have military implications I wonder?
Probably not. The earth is probably too close for it to focus.
Re: military implications
In its current form - no.
If it faced Earth, the sun would destroy its mirrors, which are chilled close to absolute zero.
However, the concept of a huge unfolding segmented mirror in Earth orbit definitely has military value.
The final price tag would be another issue, of course.
From memory, current spy satellites cost about $1 billion, just 10% of what Webb costs.
Yea what are the doing with that Web Hubble telescope?
