Very cool & interesting. Also interesting is that only 91 of these craft were built & delivered -- that seems like such a tiny number. And, apparently, only 68 are earmarked to be kept & maintained ('SLEP') it seems: "All of the planned 91 craft have been delivered to the Navy. A Service Life Extension Program (SLEP) is currently in progress to add 10 years of service life to the craft design life. A total of 68 LCAC will have undergone service life extension by the conclusion of the program in 2021."
