I heard that spinning the missile renders laser defense useless. I have not seen spinning the missile mentioned in this article, perhaps by intent of the author.


Towards the bottom of the article...

> Could platforms defend themselves? What if the warhead or missile was spinning, etc.? All those questions were answered. The only real barrier at the time was generating very high laser power levels in a way that was logistically practical in the field.


"Just add three or four orders of magnitude to the power output and we're good to go!"


It's mentioned in this paragraph:

"When we were developing this technology in earnest for missile defense 15 years ago, there were many theories about how it could be defeated. People thought that mirrored surfaces might just reflect the beam. It turned out that reflective surfaces are actually more vulnerable. Would the range be far enough? Maybe the atmosphere would scatter the beam too much? Could platforms defend themselves? What if the warhead or missile was spinning, etc.? All those questions were answered. The only real barrier at the time was generating very high laser power levels in a way that was logistically practical in the field."


“Reflective surfaces are more vulnerable”? I’m gonna need a fact check on that one.


I suspect the issue is that the reflective materials are weak. That is, a heat shield would survive longer against a laser than a mirror.


Mirrors are extremely sensitive to high energy radiation. Maybe something similar happens with very powerful lasers?


Nothing is perfectly reflective, so the energy that is absorbs destroys the mirror quickly and then it becomes absorptive.
