It was a lot more than lasers, but ultimately rejected? Not really,
and certainly not due to technological obstacles. In terms of
science and technological R&D it was an extremely successful military
program. Even though the technology has been deployed incrementally
and slowly (just about every new weapon system borrows heavily from
"Star Wars" technologies), we are also talking about the development
of high-energy physics and engineering in domains that had not even
been seriously considered before. Those things take time, you can't
just pull them out of a hat.
At this point, almost all of the original "technological obstacles"
have solutions that are doing well in field trials or have been
deployed. Lasers of all scales? Check. Hyperkinetic rockets?
Check. Kinetic intercept? Check. Electromagnetic guns? Check.
None of it was impossible, it just required the development of very
advanced materials science that did not yet exist when the project
In fact, the only Star Wars technologies that I can think of that did
not produce viable capability was some of the more exotic particle
beam weapons and similar. All the rest are in late-stage field
trials, are currently transitioning to production, or are already in
production. What did change was the geopolitical situation over the
last quarter century, so the deployment patterns for the technology
are not what they originally envisioned. Most of these technologies
are actually seeing first deployment in tactical weapons since those
will have more immediate use than thousands of strategic missile
killers. Rather than mounting hyperkinetic missiles on satellites,
they are mounting them on Hummers. Which makes sense.
