If it's an orbital laser, it means it's gonna have to either have a geosynchronous orbit and be limited in it's targeting range, or needs to reach the right orbit and thus limited in time.

Is it manned? In this case, you could probably detonate a neutron bomb in near orbit to take out the crew, even if you have to kamikaze a space shuttle and crew to do it. Or is it ground controlled? In the later case, is the encryption secure? Could you take out the ground control facilities? That's assuming the guys working on it are Fanatically (as per the disadvantage) loyal to the cause. Because if they're not, you could get enough of the to defect to sabotage the whole system (which could make a good campaign premise).

It's gonna be expensive too. In D20 Modern Urban Arcana, such a kill sat has in universe been proposed, but the budget to create and operate a single platform is bigger than the DOD budget. Who put it there? Why? How are they funding it? What if you cut funding to them?

For what it's worth, how did they get it in space without anyone noticing? That's a big space project, and TL 9 (even superscience) don't tend to be capable of interstellar travel so it's likely not an alien race.

It's great for destroying High Value Targets like the Pentagon, but as son as Earth has capitulated and the remnants and sympathizers start going asymmetrical warfare, it's gonna be much less useful all of sudden. With all our late TL 8 tech, a bunch of poorly trained guys with obsolete weapons (a mixed match of TL 4-7 with some getting cheap TL 8 guns) are making a mockery of modern military.
