“Now we are getting nearer to true submarines,” PopSci proclaimed in June 1949 of the Navy’s newly revamped U.S.S. TUSK, “not just buttoned-up surface ships that can dunk for a few hours.” The TUSK, first commissioned as a torpedo boat in 1946, reemerged as a deadly spy sub capable of remaining in the deep for weeks, thanks to a snorkel that allowed its diesel engines to run underwater while its upgraded batteries recharged. This technology and a sleek aircraft-inspired design improved the sub’s speed from 10 knots to 15 knots.
