From August through November, she joined the Sixth Fleet in the Mediterranean Sea, visiting ports of Italy, France, and Sicily, before returning home. From December 1950 to April 1951 Sea Leopard was undergoing overhaul at the Philadelphia Naval Shipyard.
For the next two years, she operated in the Atlantic Ocean and Caribbean Sea, participating in fleet training exercises. In September and October 1952, Sea Leopard participated in NATO operation "Emigrant," and then cruised in Bermuda waters, until entering the Charleston Naval Shipyard in December for overhaul. Returning to duty in April 1953, the submarine operated in the vicinity of Newfoundland and Iceland in operation "Mariner," before returning to warmer waters in the Caribbean.
Sea Leopard’s second deployment to the Mediterranean took place in May and June 1954 and was followed by her participation in NATO exercise “New Broom II,” in which she made successful simulated attacks on NATO convoys. The submarine entered the Portsmouth Naval Shipyard in October for a six-month overhaul. The yard work was followed by her participation in "LantPhibEx," as a member of forces opposing a simulated amphibious assault on the coast of North Carolina.
In February and March 1956, Sea Leopard, along with other units of SubRon 6, set sail for the Caribbean and operation "Springboard." She then returned to Norfolk for local operations until March 1957, when she again joined the Sixth Fleet in the Mediterranean. In June, she participated in festivities celebrating the 50th anniversary of the Netherlands Submarine Force at Rotterdam, before sailing to Charleston, South Carolina, for an overhaul. Upon its completion in January 1958, Sea Leopard joined operation "Springboard" in the Caribbean and then returned to Norfolk for local operations. Joining Task Group Alfa, she participated in operations to develop antisubmarine warfare tactics and readiness, until undergoing restricted availability at Charleston Naval Shipyard (August to October 1959) to install a new high capacity battery.
