Navy Bill
Navy Bill is a sculpture of the United States Naval Academy's mascot, "Bill the Goat", a billy goat. It was designed by Clemente Spampinato in 1956, and presented to the Academy in 1957. Until 2010, the sculpture stood just inside Gate 1 to the Academy. Following a five-year refurbishment underwritten by the Class of 1965, the statue was returned to Gate 1. A second statue commissioned by the Class of 1965 was placed in the north end zone of Navy–Marine Corps Memorial Stadium on 9 June 2015. It was rededicated 24 October 2015. "Navy Bill" has the alternate name of "Goat Mascot".
Presidential Unit Citation (United States)
The Navy version has navy blue, yellow, and red horizontal stripes, and is the only Navy ribbon having horizontal stripes. To distinguish between the two versions of the Presidential Unit Citation, the Navy version which is more often referred to simply as the Presidential Unit Citation, is referred to as the Navy Presidential Unit Citation and sometimes as the "Navy and Marine Corps Presidential Unit Citation", the Army and Air Force version is referred to by the Army and Air Force as the Army Presidential Unit Citation and Air Force Presidential Unit Citation. The ribbon is worn by only by those Navy and Marine service members who were assigned to the unit for the "award period" of the award. In the Army, those who join the unit after the "award period" may also wear it while assigned to the unit. ALNan 137-43 states that the first award has a blue enameled star on the ribbon and additional stars for subsequent awards. In 1949, the award changed with no star for the first award and bronze stars for subsequent awards. 
To commemorate the first submerged voyage under the North Pole by the nuclear-powered submarine in 1958, all members of her crew who made that voyage were authorized to wear their Presidential Unit Citation ribbon with a special clasp in the form of a gold block letter N.
