How to Make a Giant Chain Gun Even Deadlier: Give It a Laser Cannon

• Clay Dillow via

BAE System’s Mk 38 chain gun was already a formidable opponent: a 250millimeter cannon capable of putting 180 rounds per minute into the air from the deck of a naval ship, strongly urging those without clearance to keep a safe distance (of about 2,000 yards). But in a tip of the hat toward what the U.S. Navy considers the future of shipboard defense, BAE and Boeing have teamed up to accessorize the Mk 38 with a laser death ray. You know, just in case.

Yesterday, the two defense contractors announced that they are jointly developing a demonstration model Mk 38 with dual capabilities. The chain gun--originally designed to be manually aimed and fired--will now be remote-controlled and use an electro-optical/IR sensor ball to detect and track incoming targets, like UAVs or small watercraft (like the one that perpetrated the attack on the USS Cole in Yemen several years ago).

But according to a BAE-Boeing announcement, “the system also provides the ability to deliver different levels of laser energy, depending on the target and mission objectives.” Danger Room tells us that the fiber laser system can pack up to 10 kilowatts of punch, far below what the U.S. military has previously considered weapons grade but nonetheless effective--just a few months ago an Office of Naval Research laser fried the engine of a small watercraft with a 15 kilowatt beam (though that was designed to be scaled up to a more impressive 100 kilowatts).

Does anybody proofread anything anymore, or is such done only by those who are scientifically and technically illiterate? 250mm??? cannon. Really??? a gun that fires 3, 10 inch rounds per second. You really think so?   yes 250 mm is 10 inches, the size of a main gun on a cruiser.
