Only to a limited degree. We have a pretty good idea of the state of the art in lasers, acoustic weapons and other areas. Whilst therte may be some
exotic weapons developments which were not pursued in the white world (in particular int he nuclear field) it would be very irresponsible to waste
billions on developments which would never be of any use. Nukes, at least, have a deterrent value; a weapon that you don't tell anyone about doesn't
even have that.
Besides, I don't think it's likely to impress aliens. Anyone capable of interstellar travel is likely to have rather better technology.
