Windows NT made it onboard a Navy guided missile cruiser with these
results:

The US Navy's so-call "Smart Ship technology" left the Aegis missile
cruiser USS Yorktown dead in the water off the coast of Cape Charles,
Va. for several hours. The shutdown of the ship's propulsion was
credited to a database overflow in a Windows NT system. The crash was
caused by the inability of the OS to properly handle division by
zero. Said Anthony DiGiorgio, a civilian engineer with the Atlantic
Fleet Technical Support Center, "Using Windows NT, which is known to
have some failure modes, on a warship is similar to hoping that luck
will be in our favor." The Navy is still expected to spend $138
million expanding the "Smart Ship" program to the entire Aegis class,
and to other ships in the fleet. (Government Computer News, 13 July
