Wilkins next offered his service to the U.S. Army which retained him to teach Arctic survival skill to U.S. soldiers. After the war he remained as a consultant to the U.S. Army. The United States Navy were developing nuclear submarines for sub ice travel in the Arctic and consulted Wilkins on his pioneering 1931 expedition. Wilkins died on 30 November 1958 in a hotel room in Massachusetts. As a mark of respect the U.S. Navy took his ashes to the North Pole in the nuclear submarine Skate. On 17 March 1959 the Skate became the first submarine to surface at the Pole, where it held a memorial service and scattered the ashes of Sir Hubert Wilkins.
