Two Sailors Injured When Drone Crashes Into US Navy Guided Missile Cruiser 109
Hugh Pickens DOT Com writes "CNN reports that two sailors were hurt when a drone malfunctioned and crashed into the Chancellorsville, a 567-foot Ticonderoga-class guided missile cruiser, as the ship operated off the Point Mugu area of Southern California in an area where BQM-74E aerial targets are widely used. The drone was being used to test the ship's radar tracking when it malfunctioned, veered out of control and struck the cruiser. 'No sailors were seriously injured, but two sailors were treated for minor burns,' the Navy said in a statement. 'The ship remains capable of operations. However, it did sustain some damage and will return to its homeport of San Diego to have the damage assessed. The Navy is investigating the cause of the malfunction.' Chancellorsville has one of the most advanced air defense systems in the Navy, and the ship regularly tests missiles off Southern California. In late August, Chancellorsville successfully used an SM-6 missile to hit a target drone off Point Mugu. The cruiser stocks a variety of missiles, including Tomahawks."

I strongly suspect (though I'm not interested enough to actually research it) that modern (and not so modern, battleships were going out of style long ago) anti-ship weaponry is deadly enough that the amount of armor required to defend against it would not be practical. Thus you instead make ships that are harder to it, and if one gets through the active defenses you are done anyway - so there's not much point in heavy armor.

Hi folks, anonymous Fire Control education available here.
A little research will show that the Chancellorsville received an Aegis Modernization upgrade last year, and earlier this year also had their combat system software patched again.
The ship was likely involved in a Detect-to-Engage scenario with the BQM-74 drone acting in an anti-ship missile profile, or enhanced to provide a radar return like a strike aircraft (Source: wikipedia)
In this sort of scenario, whether off the California or Hawaiian coasts, the ship's weapons systems are SAFED. The firing inhibt keys are in place. The ship cannot actually fire. There are scenarios where the drone would be fired upon, but generally with dummy munitions, and the telemetry would be recovered from the drone to indicate if the ship would have had a successful hit.
Given that I've done these particular exercises before in my (previous) career, it sounds like the first scenario. They were testing the newest software to ensure that the combat system internally processed the drone's attack profile correctly and the ship was able to successfully send engagement and targeting data to the weapons systems, without actually releasing any munitions.
Having served on an identical guided missile cruiser to the Chancellorsville, I can also discuss conjecture about ship's armor. We're not really armored like people think of anymore. The superstructure on modern ships contains a lot of aluminium, to save weight. (this also causes significant corrosion problems in older ships) Especially in the case of the top-heavy deckhouses of an Aegis Cruiser. The critical spaces in the superstructure DO have armor, but this is more to ensure that blast fragments don't penetrate. A direct hit on a critical equipment room would still cause significant damage.
http://www.10news.com/news/military/malfunctioning-drone-hits-san-diego-based-navy-ship-uss-chancellorsville-while-training-2-injured
This link contains video showing the puncture from the drone striking the ship. It punctured like this because you're looking at a thin bulkhead; there's a covered exterior passageway right there through the deckhouse on both port and starboard side. Interior to that are a couple of gear lockers; again, inconsequential and unarmored. Deeper in than that you would find some armored spaces.
Likely the fuel from the drone ignited, causing a small fire and damaging these gear lockers and assorted deck equipment kept within. My ship kept the small skiff used for painting the hull inport stored there, along with rope and other lines.
I'm interested in how/why Point Mugu lost control of the drone.
