Ghosts of the East Coast:  Doomsday Ships

By Karl C. Priest January 16, 2006  (revised 11-4-18)

In the early stages of the Cold War an impending "Doomsday" weighed heavily upon the minds of Americans. President Truman instituted the Federal Civil Defense Administration which began issuing brochures, films, and radio advertisements to prepare citizens to survive a nuclear attack.  Dog tags were issued to many school children who also went through "duck and cover" drills as they were trained to curl up under their school desks after a nuclear bomb detonation flash of light.  Siren tests sounded at regular intervals and national and local publications ran articles about the imminent danger of nuclear war. Radios dials were marked with triangles at stations that would be used by CONELRAD (1)  broadcasts which would kick in as soon as all regular broadcasts ceased after the alarm sounded. Some American citizens were building backyard bomb shelters while local government, as well as private corporations, established larger shelters under various buildings.  Many believed the best of these efforts were hopeless in the event of a nuclear nightmare.

The military kept strategic bombers in the air and submarines at sea. The subs carried ballistic missiles (SLBMs--Submarine-Launched Ballistic Missiles) which provided a mobile and stealth means of carrying powerful nuclear firepower.  A Ballistic Missile Early Warning System (BMEWS) was developed to detect missile launches coming in from Russia.  A DEW (2) line consisting of enormous radar structures was established to warn against nuclear attack coming across the North Pole. Each side raced to gain nuclear superiority with Intercontinental Ballistic Missiles (ICBMs).  The United Sates developed Multiple Independently Targetable Re-entry (MIRV) weapons.  Although not an official strategy of the military, a concept that emphasized neither side would survive a nuclear war was known as Mutually Assured Destruction (MAD).

Nevertheless the United States government made contingency plans for Continuity of Government (COG) in the event of a nuclear attack.  Several Command Posts were developed as part of a Doomsday Plan to relocate the President (with his Emergency Action Documents--EADs), Joint Chiefs, Cabinet, Supreme Court, and Congress to secure locations.  These Alternate Joint Communication Centers (AJCC) were part of the National Military Command System (NMCS).  There were three factors that were crucial in determining the likelihood of AJCC success: (1) arriving safely at the location, (2) avoiding bomb effects, and (3) attaining important communications links.

Seeking to be victorious, in a potential nuclear war, authorities developed a plan for using the United States nuclear arsenal and designated it the Single Integrated Operational Plan (SIOP). Goals of the Doomsday Plan (a gruesome term that included SIOP, COG, and various sub-strategies) were to make sure order was preserved in society, the economy was not destroyed, food was rationed, and cultural artifacts (such as the Declaration of Independence) were rescued.  There were nuclear flash sensors placed around the country. Code words were provided for selected officials and phone numbers were given that bypassed the normal phone systems.  A broadcasting center was set up under the name Wartime Information Security Program (WISP) to control what information went to the public, including pre-recorded messages from the President. However, the ultimate goal was to make sure government survived and was able to maintain adequate information for decision making based on surveillance and analysis of world events.  To do that it was necessary to establish communications between the President and commanders of military forces as well as with leaders of allied and enemy governments.

Although government certainly consisted of several entities, the President was probably the top priority of COG for obvious political and symbolic reasons. Therefore, the President needed to be transported safely to a location that had maximum bomb avoidance and communication capabilities. Logically more than one option was made available.

Obviously, a presidential “bomb shelter” was a necessity. Code-named "Site R", and built deep under Raven Rock mountain, a Deep Underground Communication Center (DUCC) was coordinated by the Army from Ft. Ritchie near the Maryland-Pennsylvania border a few miles from Camp David.  To disperse other governmental leaders and functions other bunkers were located at Berryville, Virginia under Mt. Weather (code-named "High Point"); Culpepper, Virginia (Mt. Pony); and White Sulfur Springs, West Virginia under the Greenbrier Resort (code-named Casper). 

Some of the underground Command Posts had several hundred full time 24-hour support personnel and a capacity for maintaining about 3000 "guests".  The bunkers had thick walls of steel reinforced concrete and some had barbed wire and armed guards with dogs.  Besides communications activities the centers had individual priorities that included Federal Reserve computers, billions of dollars in currency, and Federal Emergency Management Agency (FEMA) national emergency coordinating equipment.  There were sleeping quarters, war rooms, amphitheaters, kitchens, dining areas, infirmaries, brigs, psychiatric cells, barbershops, storage rooms, sewage treatment facilities, body storage/disposal areas, gun ranges, and decontamination showers.  These were located in buildings up to four stories high.  There were detailed plans in place for every conceivable scenario including keeping a current database of medications for members of Congress.

Regarding the relocation of the President, a weakness of the DUCC was the vulnerability of the antennas needed for communication.  Also, there was the danger of sabotage (including attacks upon officials attempting to enter the bunkers) from enemy agents already inside the country.  Since the projects were so monumental when they were constructed, many people had some knowledge about the sites.

Another variable to increase the odds of the President surviving Doomsday was a moveable location which made targeting more difficult. The National Emergency Airborne Command Post (NEACP), code-named “Night Watch”, consisted of several shielded and specially configured Boeing airplanes (stationed at Andrews Air Force Base near DC) with at least one plane ready for take-off within 15 minutes after an attack alert. When the president traveled on Air Force One, a NEACP plane often flew to a nearby location.  

Weaknesses of NEACP, for presidential relocation, were getting off the ground in time, jet intakes getting fouled, and the limited amount of time the planes could stay in flight. 

A National Mobile Land Command Post (NMLCP) was proposed at one point.  Declassified documents indicate it was not recommended for implementation, but the documents found by this writer do not say why.  A submarine Command Post was also planned, but there were problems, at that time, with getting evacuated personnel aboard and having good communications abilities.  Both of these alternatives may be more viable today (2006) and are probably highly classified.

Beginning in late 1950 there was a special unit of helicopter teams (code-named "Outpost Mission") stationed at Olmstead Air Force Base in Pennsylvania.  Their duty was to fly to the White House and relocate the president to one of the sites briefly described above or to a National Emergency Command Post Afloat (NECPA).  Although the DUCC and NEACP options still exist (2006), as the "Doomsday Clock" (3) moved closer to midnight during the highly volatile 1960's, the NECPA ship was very likely the most workable choice for assurance of presidential survival had the United States been the target of a nuclear attack.

Two ships were uniquely configured and assigned the NECPA duties. (4) The NECPA ships had good maneuverability to assure safe arrival, a reasonable probability of bomb effect avoidance, and were capable of state-of-the-art communications. The sister ships USS Northampton (CC-1) (5) and USS Wright (CC-2) alternated the alert duty every two weeks as a potential floating White House/Pentagon.  The NECPA strategy was to keep one of the ships somewhere off the East Coast.  With only the customary naval acknowledgements, just outside of Norfolk, the ships would silently sail past each other as the alert ship was relieved in order to enter port for replenishing and much needed rest and recreation for the crew. 

Both the Wright and the Northampton had a huge dish-like structure used for Troposphere Scatter Communications (TROPO.) (6) There were land based TROPO dish sites located in Massachusetts, North Carolina, and Delaware. (7)  The alert ship usually operated within a few hundred miles of one of those land sites.  The gyro-stabilized TROPO equipment provided the capability for access to commercial and military telephone networks. To maintain operational security the ships took steps to decrease radio direction finding activities from hostile sources attempting to trace the location of the alert ship.  The TROPO system provided, difficult to zero in on, telephone, teletype, and data circuits with top priority for the Command Posts. The NECPA ships used voice radio call signs Zenith (Wright) and Sea Ruler (Northampton) during communication with other ships, aircraft and shore stations.

The mission of the two ships was to handle communications and command data for the strategic direction of military operations world-wide.  The ships, operated under the SIOP, and were always ready for the president (with special presidential quarters). Both ships had access to White House Situation Room classified information.  If a nuclear war had erupted the alert ship was third in line behind the Strategic Air Command (SAC) (8) and the North American Air Defense Command (NORAD), for full command to maintain Continuity of Government and control of the United States Armed Forces and nuclear weapons.  

The Wright and Northampton had interior spaces capable of pressurization to prevent contamination from nuclear fallout. The Northampton  had an exterior salt-water wash down system.  Each ship had a smaller replica of the Pentagon's War Room.  The Wright's command compartments had projection equipment with large screens and a wall of status boards and maps mounted on tracks which could be rolled into view.  One entire space was filled with teletype printers.  The crew totaled over 1,200 with 200 of those with duties just to operate and maintain the communications equipment. 

Life aboard ship (9) was tedious and stressful, mixed with friendship and macho mischief.  There were highly restricted areas where only those with appropriate security clearances were allowed to enter. Men from each branch of the military service, as well as CIA personnel, were assigned to both Wright and Northampton.  Also, many government officials and high ranking military officers from all branches of service frequently visited each ship.  The command ships were kept "spit-shined" from stem to stern, but the crews enjoyed excellent chow since the cooks requisitioned the same supplies to prepare meals for all of the ship's company and guests.  In 1968 the Wright received the prestigious Ney Award (10) for the best Large Mess Afloat for the entire fleet worldwide.

The USS Wright was the newer of the two ships both of which had been converted from previous designations (Northampton from CLC-1, cruiser, in 1961 and Wright from CVL-49, aircraft carrier, in 1963).  She had, for that era, the most elaborate and powerful communications equipment ever installed aboard a ship.  Her "voice of command" could reach any ship, aircraft, or station in the world. Two antenna masts were 114 feet tall (156 feet above the water) and able to withstand 100-mph winds.  The Wright had satellite communications (SATCOM) and carried a specially designed helicopter (11) that pulled a wire cable nearly two miles high to serve as an antenna for SVLF (Very Low Frequency) communication with submarines. A Battle “E” was awarded to the Wright in 1968 for highest scores in her Atlantic Fleet cruiser-destroyer force squadron competition.

Presidents Eisenhower, Kennedy, and Johnson went aboard the Northampton before the Wright was commissioned.  In April of 1967, the Wright accompanied President Johnson to the Latin America Summit Conference held in Uruguay.  In January 1968, the Wright was urgently called back from the Florida area and placed on high alert when the USS Pueblo was captured by North Korea.  (See author’s end note.) President Johnson traveled to Central America in July of 1968 for a meeting of the Presidents of Central American Republics.  The Wright was in the shipyards and was unable to get underway.  With short notice, the Northampton left port at about 0200, traversed the Panama Canal, and lay off the Pacific Coast of Latin America while President Johnson met with the leaders of El Salvador, Nicaragua, Costa Rica, Honduras, and Guatemala.

The NECPA ship, which was on alert, often sat just off the East Coast of the United States while running helicopter and communications operations. Coastal residents would go to bed with nothing on the horizon and awaken to see a dark, strangely shaped, ship silhouette materialize through the morning fog.  The ship would be there for a day or so and then "disappear" out to sea leaving an empty horizon.  This experience probably had the aura of a mysterious, even ghostly, occurrence.  Although it was rumored that a submarine shadowed the alert ship, as far as the eye could tell the NECPA ship cruised all alone.  At the top of each daily Deck Log for the duty ship was this entry:  "00-04 Wright is alert ship NECPA operating independently in accordance with COMCRUDESLANT (12) message 171840Z of Feb 1968". (13)

The NECPA mission was a vital part of the Cold War for almost ten years. The men who served aboard the NECPA ships served their country well and contributed to keeping the world from a nuclear holocaust.  The USS Northampton and the USS Wright were decommissioned a few weeks apart in the spring of 1970 when communication capabilities became more sophisticated. The NECPA ships also became susceptible to satellite surveillance and Soviet aircraft based in Cuba. Additionally, Soviet submarines had become more improved and numerous in the Atlantic.  Both the Wright and Northampton  were scrapped long before the United States  won the Cold War in 1991. Now, only memories remain of the East Coast “Ghost Ships" that waited for a Doomsday that did not happen on their watch.

>Two officers, aboard  each ship, had orders to be present if the top secret authentication codes for nuclear war orders were handled or transferred in any way. The codes were secured with two combination locks and each officer knew one combination.  (

>A large section of the ship was a powerful VLF transmitter, with vacuum tubes taller than an average man.  Each stage of the transmitter was contained in a separate compartment with posted designations such as "Pi Network Room".  (

>In 1960 the USS Triton traveled around the globe completely submerged. When the sub returned to America the sub surfaced off the coast of Delaware and a helicopter picked up the captain and flew him to the White House. Along with specially configured surface ships the Triton became one of the submarines used to extend the DEW line across the oceans. In the early sixties these radar-picket vessels became obsolete due to advances in technology. There is some speculation that the Triton became an alternate national command post.

>The National Military Command System (NMCS) was part of the Worldwide Military Command and Control System (WWMCCS). Because of the crucial communication and intelligence requirements, the NMCS had to “be the most responsive, reliable, and survivable system” that could be provided. (  

>Also see “Nuclear Football” (nickname for the case containing documents needed by the president to launch nuclear weapons), National Command Authorities—NCA (the top of the SIOP chain of command), and “Designated Survivor” (the Cabinet member assigned to be at a secure location while the president and other high-ranking officials are gathered together.

>The Single Integrated Operational Plan (SIOP) was the United States' general plan for nuclear war from 1961 to 2003. The SIOP gave the President of the United States a range of targeting options, and described launch procedures and target sets against which nuclear weapons would be launched. The plan integrated the capabilities of the nuclear triad of strategic bombers, land-based intercontinental ballistic missiles (ICBM), and sea-based submarine-launched ballistic missiles (SLBM). The SIOP was a highly classified document, and was one of the most secret and sensitive issues in U.S. national security policy. The first SIOP, titled SIOP-62, was finished on 14 December 1960 and implemented on 1 July 1961 (the start of fiscal year 1962). The SIOP was updated annually…

The execution of SIOP-62 was estimated to result in 285 million dead and 40 million casualties in the Soviet Union and China. Presented with all the facts and figures, Thomas D. White of the Air Force found the Plan "splendid." Disregarding the human aspect, SIOP-62 represented an outstanding technological achievement: SIOP-62 represented a technical triumph in the history of war planning. In less than fifteen years the United States had mastered a variety of complex technologies and acquired the ability to destroy most of an enemy's military capability and much of the human habitation of a continent in a single day. The first SIOP, (was) based on the massive retaliation doctrine…

During 1961–1962, the Kennedy administration revised this plan as supervised by McNamara. He aimed to change the doctrine from massive retaliation to flexible response. SIOP-63 took effect in July 1962 and remained mostly unchanged for more than 10 years. Instead of one "spasm" attack, it proposed five escalating attack options…

>The Ground-Mobile Command Center was, or is, a U.S. Army program to develop and deploy hardened and secure, mobile command posts for use by the President of the United States to command retaliation and counterattack by the U.S. armed forces in response to a catastrophic assault against North America…

Colloquially known as "doomsday trucks", ground-mobile command centers were reportedly put into service and positioned in locations around the United States that were considered unlikely to be targeted in an initial nuclear volley launched by a warring state. According to one report these locations were in Colorado and Nebraska They would be supported by co-located fuel depots and spare parts. As intended, the vehicles would not be the primary transportation mode for the president, but would rather be used only after the air evacuation of the National Command Authority from an area of danger at which point they would "gradually take over full command operations in the post-attack period".

Similar programs
The United States Northern Command (USNORTHCOM) operates a "mobile consolidated control center" (MCCC) for use by the combatant commander (CCDR) as an "alternative HQ" for coordination of emergency and counteroffensive operations following a mainland invasion of the United States. The MCCC consists of a convoy of trucks described as a "survivable, road-mobile backup" from which the CCDR can command U.S. military forces in repelling an attack, should primary and secondary facilities be destroyed or overrun.

“Trucks Tested as Nuclear Strike Posts

The (18-wheel tractor-trailer) trucks, known formally as Ground Mobile command Centers, are part of a broader program known as the World Wide Military Command and Control System or WWMCCS.

1. CONELRAD (Control of Electromagnetic Radiation) was intended to prevent enemy aircraft from using commercial radio frequencies for navigational guidance.  In 1963 this gave way to the  Emergency Broadcast System. 

2. DEW (Distant Early Warning) was a line of radar towers (resembling huge billboards) that were constructed beginning in 1954. The purpose was to detect an over-the-pole attack from long-range bombers or missiles. The line ran from Alaska, across Canada , to Greenland and connected to similar sites running from Iceland to England. The communication system used was TROPO which included a tie in to Europe.

3.The "Doomsday Clock" is symbolic for nuclear destruction at midnight.  It was originated in 1947 by scientists at the University of Chicago and set at seven minutes before midnight.  Depending on the world situation the clock was moved forward or backward. In 1968 it was moved from twelve minutes until midnight to seven minutes before midnight.  It was moved back three minutes in 1969 due to the Non-Proliferation Treaty and in 1972, with the Strategic Arms Limitation Treaty (SALT I) the clock was moved back to twelve minutes until midnight.

4. The USS Saipan (CVL-48) was begun as CC-3, but was changed to a Communication Major Relay ship (AGMR-2) and renamed the Arlington.

5. Command Communications

6. TROPO communication was an alternative for use along with short-wave and trans-Atlantic cables. The technique was to beam a signal above the horizon where the earth’s curvature would allow the signal to reach the troposphere where the signal would scatter downward beyond the horizon.,,sid9_gci333317,00.html

7. These facilities were Otis Air Force Base at Cape Cod, MA; Cedar Island, NC (operated by an officer and about 12 enlisted men); and—the largest—at Lewes, DE. The Lewes site was at Ft. Miles on Cape Henlopen. A photo of the Lewes TROPO towers is located at

8. In case the SAC Command Center was somehow disabled, the back-up plan was to keep a plane in the air which could mirror the SAC ground functions. This program was known as “Looking Glass” and operated 24/7 year round from 1961 until 1990 when the planes were placed on ground alert.
