Office of the Historian centers Targeting of such facilities is accorded the highest priority equivalent to targeting nuclear weapons of opposing forces In the case of intercontinental conflict there is no direct evidence of recent vintage However a considerable body of indirect evidence suggests that targeting priorities are similar TS Although direct evidence of Soviet intentions is not available it is considered highly unlikely that the Soviet Union would launch a major intercontinental strike against U S military forces that would not include strikes against key command control and communications centers including the National Command Authority NCA Since the locations of the primary U S federal relocation sites are publicly available it is again considered highly unlikely that these would not be targeted Thus it must be assumed that the Soviet Union would apply as many weapons as necessary to ensure the destruction of these key sites The single warhead versions of the SS–17 SS–18 and SS–19 in particular the SS–18 would be the most likely candidates for attacking 1 line not declassified given our estimate of their damage expectancy S There is some dated evidence of Soviet intent to use SLBMs against command posts and communications centers Although current Soviet SLBMs have a much lower damage expectancy than more modern ICBMs SLBMs have the advantage of shorter flight times which reduce the amount of warning time available However it is not believed that the Soviet Union would consider a “decapitation” attack alone that is one aimed solely at the NCA command and control to be adequate to Page 843 attain their war-fighting objectives Thus an attack against the NCA would almost certainly be part of a large scale strike against U S military forces S The length of strategic warning of nuclear attack would depend on the circumstances of the crisis leading to the attack The intelligence community however has estimated that war in Europe “would be preceded by a period of extreme tension in a crisis of unprecedented severity ” The Soviet Union apparently believes that a period of increased tension will precede any major use of military forces The intelligence community believes that there is virtually no chance that the Soviet Union would attack NATO countries from a standing start and the majority view is that the USSR and the Warsaw Pact would take at least eight days of preparation before initiating hostilities in Europe However “strategic warning” cannot be regarded as something that can be provided with any degree of precision since it depends as much on the interpretations and perceptions of the national policy authorities as it does on any array of intelligence evidence Annex C Paper Prepared in the National Security Council3 Washington undated ALTERNATIVE CONCEPTS FOR PRESIDENTIAL SUCCESSOR SUPPORT Over the past several years a number of studies have been conducted to evaluate various concepts to improve the survivability and endurance of the Presidency in a protracted nuclear conflict These concepts include — Submarine Emergency Alternate Command Post SEACP — Maritime surface vessels — Airborne systems including the NEACP — Land-based systems All are motivated by the basic need for the Presidency to survive and function over extended periods of time in a nuclear environment https history state gov historicaldocuments frus1977-80v04 d197 2 5 4 15 24 10 30 AM Foreign Relations of the United States 1977–1980 Volume IV National Security Policy - Office of the Historian The following outlines the major conclusions of these efforts and offers some thoughts on directions various basing platforms might go SEACP Page 844 A recent Navy study concluded that it would be feasible to convert a POLARIS SSBN to perform most of the missions associated with a national-level command post However the concept was judged to be deficient in the following areas — Safe and timely embarkation of the President or successor would present major problems It would be extremely difficult to effect a timely rendezvous with a SEACP — The pre-attack and early trans-attack survival of a submarine command post is dependent upon its ability to remain undetected by the enemy Its location would be compromised and its probability of survival reduced if it were to tie into tactical warning and attack assessment communications networks — It is doubtful that submarine communications technology would support the volume of communications traffic which would be associated with the President’s functions Submarines are normally not required to effect a great deal of transmissions their communications systems are focused on receiving — Dedicated submarine platforms are extremely costly It was apparent from the study that the SEACP is not a cost-effective platform for Presidential survival However submarines do offer potential for other key COG functions such as the reconstitution of C3I systems which are destroyed during the early stages of a nuclear conflict Surface Vessels Navy Coast Guard and even merchant vessels can be configured to carry special communications and support packages for the President Surface vessels offer advantages in mobility and flexibility The proliferation of ships in different locations would enhance survival through dispersion However surface vessels have some significant shortcomings as well — Connectivity with surviving domestic telephone nets would be tenuous from the high seas The volume of radio communications which would be necessary to support Presidential functions would provide an EM signature which could jeopardize the vessel — Dedicated and proliferated platforms would be costly This was the experience with the NORTHAMPTON a cruiser formerly dedicated to the COG role — Surface vessels are vulnerable to submarine attack especially if the ship has been identified prior to the conflict as a highvalue target Under those circumstances such a vessel would probably have a submarine tail at all times — There may be come some political liability associated with the President leaving the continental United States An alternative seaborne concept of considerably less cost is to develop our land-based systems such that they are readily deployable on ships tugs or barges which could operate on inland waters or in coastal areas This would provide an additional measure of flexibility and mobility in a COG system Airborne Platforms Our current COG system relies heavily upon airborne assets 5 lines not declassified The less than 1 line not declassified also has some major drawbacks — 6 lines not declassified — https history state gov historicaldocuments frus1977-80v04 d197 3 5 4 15 24 10 30 AM Foreign Relations of the United States 1977–1980 Volume IV National Security Policy - Office of the Historian C3 and staff configuration are such that the President will probably be unable to execute his functions as Chief of State or Chief Executive in addition to his requirements to command theater nuclear and conventional forces For these reasons it would be imprudent to rely exclusively upon less than 1 line not declassified As with seaborne platforms it may be possible to combine a land mobile system with airborne carriers such as C–130s Under this concept the land-based system could embark on aircraft and be moved to various parts of the country depending upon the attack pattern Land Based System Several land based deployment concepts were also evaluated by the Working Group For analytic purposes these deployment modes were treated as discrete sets Operationally these concepts could clearly be mixed Other somewhat different modes of deployment could evolve and expansions of specific mixtures could be developed in response to a changing threat Detailed analyses were performed on basing modes with a dedicated prepared sites and stationary or semi-mobile operation b designated unprepared sites and stationary or semi-mobile operation and c a fully ground mobile concept —Dedicated Prepared Sites Sites are selected in low-risk areas and will have fall-out protection connectivity to the commercial telephone system life support supplies and access to designated ground vehicles Since these preparatory steps are austere some added advanced preparation may be required Depending on the threat from 20 to 650 of these sites were used in the analysis If used in stationary operation all sites must be equipped with full communications packages The successor and his team would disperse at random to one of the sites and leapfrog between the sites In semi-mobile operations mode the number of communications packages would be reduced to 2–4 per potential Page 846 successor These packages while not fully mobile would be moveable and would permit some limited communications while on the move The successor could move at random between sites using designated vehicles or aircraft —Designated Unprepared Sites Again sites should be located in such buildings as motels schools armories or small federal civil or military installations In the stationary operating mode a site would be activated at random by dispersing communications and support packages to the site Successors and their support team would then be dispatched to the activated site in designated vehicles or aircraft In the semi-mobile operating mode between 2 to 4 semi-mobile support groups communications and support packages per successor would move at random between sites Teams would have limited communications while on the move in designated support vehicles —Fully Mobile Operations Ground-mobile operation can be achieved by having the successor joint a fully-equipped caravan in a relatively low-risk area with little possibility for exposure to fall-out Three caravans per successor were used in the analysis The teams relied on fuel and food caches in the area nevertheless their endurance would be limited Other full mobile deployment modes have been evaluated in previous analyses Alternates such as submarines fully airborne and shipborne operations were excluded for reasons of cost limited communications and reduced endurance Evaluation The five basing modes were then evaluated on the basis of the following parameters — Survivability which depends on the threat Soviet weapons availability yield and accuracy the enemy’s intelligence capability to detect and acquire an evading successor U S protective measures consisting of hardening and the extent of location uncertainty which can be introduced through secrecy proliferation of sites or mobility — https history state gov historicaldocuments frus1977-80v04 d197 4 5 4 15 24 10 30 AM Foreign Relations of the United States 1977–1980 Volume IV National Security Policy -
