Interesting, but the hospital ship should not have any weapons, not even SeaRAM.
Yeah, that's something I was considering as well. But what is considered as defensive weapons tho? For this specific ship I actually read upon the Hague Peace Conference of 1907 and as far as I understand, the 1907 Hague Convention for Adaptation to Maritime Warfare of the Principles of the Geneva Convention states:
"The fact of the staff of the said ships and sick wards being armed
for maintaining order and for defending the sick and wounded, and
the presence of wireless telegraphy apparatus on board, is not a
sufficient reason for withdrawing protection. "
The protection being, the fact that you cannot open fire on those ships. Now, the question is, what exactly is "being armed for maintaining order and for defending the sick". It's important to remember that its year 1907 when this convention is written. Back then, this probably only applied to small arms. Mercy and Comfort both carry small arms and crew-served machine guns:
"The ESTs defend against terrorists and pirates by using automatic weapons, such as this M-240 light machine gun mounted on the rail of MSC hospital ship USNS Mercy while she was underway in support of Operation Unified Assistance."
Now, its exactly 111 years since the Hague Convention, back then a guided missile would be just a science fiction. Is it too much to presume that SeaRAM ,anti-missile defense system, does not violate the spirit of the convention? Specifically the part about "defending the sick"?
