"Not much else is known: Its power is strangely classified, but the laser likely operates in the 15 to 50 kilowatt range"
"It also presumably excludes the cost of shipboard electrical power, likely in the thousands of watts, that would be needed."
Impressive efficiency, lasers do well to be 10% efficient so 100KW would be a decent baseline power. They should have said hundreds of thousands of watts.
Probably just bad editing but not a good sign about this article.
