I almost forgot that there was also mention of the material used on the Mark 18 for vane pivots... or maybe the friction bearing? I cannot remember... but due to the environment on a submarine, submerged in the saltwater and humidity of the ocean over time, the pivot points had a tendency to corrode, contributing to the stuck condition of the vanes, in that the gyro could not "pull" the vane back once it went over, so whereas the Mark 14 would run erratically, the Mark 18 just turned into a circle runner...
