1954 – Launching of Nautilus, first nuclear submarine, at Groton, CT. Construction of NAUTILUS was made possible by the successful development of a nuclear propulsion plant by a group of scientists and engineers at the Naval Reactors Branch of the Atomic Energy Commission, under the leadership of Captain Hyman G. Rickover, USN. In July of 1951 Congress authorized construction of the world’s first nuclear powered submarine. On December 12th of that year, the Navy Department announced that she would be the sixth ship of the fleet to bear the name NAUTILUS. Her keel was laid by President Harry S. Truman at the Electric Boat Shipyard in Groton, Connecticut on June 14, 1952. After nearly 18 months of construction, NAUTILUS was launched with First Lady Mamie Eisenhower breaking the traditional bottle of champagne across NAUTILUS’ bow as she slid down the ways into the Thames River.
Eight months later, on September 30, 1954, NAUTILUS became the first commissioned nuclear powered ship in the United States Navy. On the morning of January 17, 1955, at 11 am EST, NAUTILUS’ first Commanding Officer, Commander Eugene P. Wilkinson, USN, ordered all lines cast off and signaled the memorable and historic message, “Underway On Nuclear Power.” Over the next several years, NAUTILUS shattered all submerged speed and distance records. On July 23, 1958, NAUTILUS departed Pearl Harbor, Hawaii under top secret orders to conduct “Operation Sunshine,” the first crossing of the north pole by a ship. At 11:15 pm on August 3, 1958, NAUTILUS’ second Commanding Officer, Commander William R. Anderson, USN, announced to his crew “For the world, Our Country, and the Navy – the North Pole.” With 116 men aboard, NAUTILUS had accomplished the “impossible,” reaching the geographic North Pole–90 degrees north. In May 1959, NAUTILUS entered Portsmouth Naval Shipyard, Kittery, Maine for her first complete overhaul–the first of any nuclear powered ship–and the replacement of her second fuel core.
Upon completion of her overhaul in August 1960, NAUTILUS departed for a period of refresher training, then deployed to the Mediterranean Sea to become the first nuclear powered submarine assigned to the U.S. Sixth Fleet. Over the next six years, NAUTILUS participated in several fleet exercises while steaming over 200,000 miles. In the spring of 1966, she again entered the record books when she logged her 300,000th mile underway. During the following 12 years, NAUTILUS was involved in a variety of developmental testing programs while continuing to serve alongside many of the more modern nuclear powered submarines she had preceded. In the spring of 1979, NAUTILUS set out from Groton, Connecticut on her final voyage. She reached Mare Island Naval Shipyard, Vallejo, California on May 26, 1979–her last day underway.
She was decommissioned on March 3, 1980 after a career spanning 25 years and almost half a million miles steamed. In recognition of her pioneering role in the practical use of nuclear power, NAUTILUS was designated a National Historic Landmark by the Secretary of the Interior on May 20, 1982. Following an extensive historic ship conversion at Mare Island Naval Shipyard, NAUTILUS was towed to Groton, Connecticut arriving on July 6, 1985. On April 11, 1986, eighty-six years to the day after the birth of the Submarine Force, Historic Ship NAUTILUS, joined by the Submarine Force Museum, opened to the public as the first and finest exhibit of it’s kind in the world, providing an exciting, visible link between yesterday’s Submarine Force and the Submarine Force of tomorrow.
1960 – Little Joe 1B, a Mercury spacecraft, lifts off from Wallops Island, Virginia with Miss Sam, a female rhesus monkey on board. The Little Joe 1B was a Launch Escape System test of the Mercury spacecraft, conducted as part of the U.S. Mercury program. The spacecraft was recovered by a Marine helicopter and returned to Wallops Island within about 45 minutes. Miss Sam was one of many monkeys used in space travel research.

1968 – One of the most publicized and controversial battles of the war begins at Khe Sanh, 14 miles below the DMZ and six miles from the Laotian border. Seized and activated by the U.S. Marines a year earlier, the base, which had been an old French outpost, was used as a staging area for forward patrols and was a potential launch point for contemplated future operations to cut the Ho Chi Minh Trail in Laos. The battle began on this date with a brisk firefight involving the 3rd Battalion, 26th Marines and a North Vietnamese battalion entrenched between two hills northwest of the base. The next day North Vietnamese forces overran the village of Khe Sanh and North Vietnamese long-range artillery opened fire on the base itself, hitting its main ammunition dump and detonating 1,500 tons of explosives. An incessant barrage kept Khe Sanh’s Marine defenders, which included three battalions from the 26th Marines, elements of the 9th Marine Regiment, and the South Vietnamese 37th Ranger Battalion, pinned down in their trenches and bunkers. Because the base had to be resupplied by air, the American high command was reluctant to put in any more troops and drafted a battle plan calling for massive artillery and air strikes.
During the 66-day siege, U.S. planes, dropping 5,000 bombs daily, exploded the equivalent of five Hiroshima-sized atomic bombs in the area. The relief of Khe Sanh, called Operation Pegasus, began in early April as the 1st Cavalry (Airmobile) and a South Vietnamese battalion approached the base from the east and south, while the Marines pushed westward to re-open Route 9. The siege was finally lifted on April 6 when the cavalrymen linked up with the 9th Marines south of the Khe Sanh airstrip. In a final clash a week later, the 3rd Battalion, 26th Marines drove enemy forces from Hill 881 North. Gen. William Westmoreland, commander of U.S. Military Assistance Command Vietnam, contended that Khe Sanh played a vital blocking role at the western end of the DMZ, and asserted that if the base had fallen, North Vietnamese forces could have outflanked Marine defenses along the buffer zone. Various statements in the North Vietnamese Communist Party newspaper suggested that Hanoi saw the battle as an opportunity to re-enact its famous victory at Dien Bien Phu, when the communists had defeated the French in a climactic decisive battle that effectively ended the war between France and the Viet Minh. There has been much controversy over the battle at Khe Sanh, as both sides claimed victory. The North Vietnamese, although they failed to take the base, claimed that they had tied down a lot of U.S. combat assets that could have been used elsewhere in South Vietnam.
This is true, but the North Vietnamese failed to achieve the decisive victory at Khe Sanh that they had won against the French. For their part, the Americans claimed victory because they had held the base against the North Vietnamese onslaught. It was a costly battle for both sides. The official casualty count for the Battle of Khe Sanh was 205 Marines killed in action and over 1,600 wounded (this figure did not include the American and South Vietnamese soldiers killed in other battles in the region). The U.S. military headquarters in Saigon estimated that the North Vietnamese lost between 10,000 and 15,000 men in the fighting at Khe Sanh.
