The museum should take about one hour to visit and the Nautilus visit about 30 minutes. The museum is open May 15 through October 31, Wednesday through Monday from 9 a.m. until 5 p.m., and Tuesdays from 1 p.m. to 5 p.m. Unofficial history, however, dates back much further. Egyptian hieroglyphics, uncovered in the Nile Valley, illustrate how early duck hunters used to creep up on their prey from beneath the surface, breathing through hollow papyrus reeds. At the time, SubRoc was the standard weapon aboard most U.S. nuclear attack submarines.
