Matveyev Doctor of-Technical Sciences, Professor. and Engineer Major Yu. Orlov, Candidate of Technical Sciences Nuclear surface bursts are still employed rarely in operational training or in troop exercises to accomplish various tasks in an operation. In our view, this is explained, on the one hand,.by . ear of the e f fec__t of radioactive contamination of the terrain on our own troops and fear of-limiting their maneuver capability as and, on the other hand, by an incomplete picture of the effectiveness of such bursts in destroying enemy personnel. Indeed, if there is a moderate wind blowing toward our troops, there does exist a certain danger that our personnel will receive unacceptable doses of radiation, depending on the depth and yield of the nuclear strikes. Thus, in respect to the nuclear warheads considered in this article, the safety of our own troops can be assured only when destroying groupings which are at least 150 to 200 kilometers from the line of combat contact. If the wind is blowing toward the enemy, it becomes possible to destroy advancing troops only when they reach the areas in which the nuclear strikes are to be delivered or in actions on contaminated terrain (mainly when they are negotiating zones of radioactive contamination). However. 24 ky rs after the delivery of a aroun,nurlpar strike the leveler of tion harless. In this case, the possibility of using surface bursts-will be determined by the ra.te.s _.of advance. And it may be assumed that, on the average, under favorable conditions, group nuclear strikes with surface bursts can be delivered against enemy targets located at a distance of 50 to 100 kilometers from the forward units of the advancing troops.

In addition, surface nuclear bursts will not only destroy personnel and combat equipment in the enemy's operational rear but will create broad zones of radioactive contamination which will immobilize his troops and prevent the approach of reserves and the bringing up of materiel to the battlefield. The present article offers an approximate methodology for planning the destruction of groupings of troops in concentration areas with surface nuclear bursts, and substantiates the need for calculating the destruction of enemy personnel from radioactive contamination of terrain. It is known that a surface nuclear burst causes radioactive contamination of terrain both in the area surrounding the center of the burst and along the path taken by the radioactive cloud. And although the zone of radioactive contamination of terrain in the center of the burst is considerably smaller than the total zone of destruction (from the shockwave, thermal radiation, and penetrating radiation) and does not inflict any additional destruction on the enemy within this area, enemy personnel along the path of the radioactive cloud may be destroyed at distances of tens, and sometimes even hundreds, of kilometers from the center of the burst. The putting of personnel out of action during radioactive destruction depends on the dose of radiation they receive while on contaminated terrain. It is characteristic of this situation that the number of personnel put out of action by one and the same dose of radiation will change with time. Thus calculations show that if a dose of radiation equal to 300 roentgens is received, only 10 percent of the personnel will be put out of action during the first hour (after receiving the dose), while 85 percent will be out of action by the end of the Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 6 of 22 Pages first 24 hours (i.e., by this time a unit or subunit will have lost its combat effectiveness completely). 50X1-HUM The following factors, in addition to the length of time spent on radioactively contaminated terrain, influence the amount of the dosage: the yield of the nuclear warhead, the distance of the target from the center of the burst, the average wind direction and velocity, the degree of cover (protection) of personnel, the type of ground on which the burst occurs, forested areas in the path of the fallout pattern from the cloud, atmospheric precipitation during formation of the radioactive fallout pattern, and other factors. The first four factors are taken into account directly in the calculation formulas for determining the radiation doses which are correct for non-friable soils (clay, loam, rock), for exposed and semi-exposed terrain, and for when there is no atmospheric precipitation. If nuclear bursts take place on sandy soils, the level of radiation within the fallout pattern from the cloud will increase on the average by a factor of 2.5. The degree of contamination of terrain and atmospheric precipitation will increase to a certain extent. Large tracts of forest (because of the settling of radioactive dust on the crowns of trees and because of the screening effect of the forest) reduce the radiation level by a factor of about two. However, such protective features are characteristic only of forested areas which have not suffered the effects of a shockwave and thermal radiation; the features are considerably weakened in a zone of massive employment of nuclear weapons. Before proceeding to set forth the essence of the proposed methodology, let us examine the basic factors which determine the effectiveness of using surface nuclear bursts. The amount of damage inflicted upon the enemy will be considerably affected by the degree of detection of the grouping being destroyed, the average wind direction, the location of our aiming points, and a number of other circumstances, as well as by the number of missiles employed and their yield. 50X1-HUM Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 7 of 22 Pages 50X1-HUM Degree of detection (reconnaissance of targets. Reliable knowledge of the position and nature of the individual targets of the enemy grouping being destroyed makes it possible to correctly determine the aiming points of the missiles and to efficiently allocate the available yields of nuclear warheads among the planned targets. However, it is an exceptionally complicated task to establish the position of all of the targets, let us say, of a division located in a concentration area. At the same time, there is no particular need to do this when delivering a group nuclear strike (with 6 to 10 missiles). An analysis of the effect of the degree of detection (0) of the targets of a division located in a concentration area on the effectiveness of a group strike (made on the basis of comparative estimates) has shown that there will be an appreciable increase in the average losses of a division only if the degree of detection rises to 30 to 50 percent. A further rise in this percentage will have no practical effect on the effectiveness of a group nuclear strike. This feature of dependence of average losses on the degree of detection of individual targets is explained by the fact that when 0 = 30 to 50 percent, a large portion of the planned nuclear strikes are being delivered against specific targets (and are consequently being employed with maximum effectiveness). The expenditure of missiles in this case, if the nuclear warheads are of equal yield, will be about 1.5 times less than when 0 = 0. The average wind velocity and direction constitute basic factors affecting the formation of the fallout pattern of the nuclear cloud. If nuclear strikes are delivered directly on a grouping of troops, the average wind seed does not appreciably affect the a ectiveness o destroying it (although with an increase in wind velocity, some increase in average losses is noted. The average wind direction may strongly affect the amount o damage inflicted on the enemy by acting on the zones of radioactive contamination and expanding them beyond the bounds of the grouping being destroyed, if the nuclear strikes are planned without considering wind direction. Thus, in computer simulation of a group nuclear strike against an armored division in a concentration area Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 8 of 2750X1-HUM (6 missiles with a yield of 100 kilotons each) with a change in wind direction from 180 to 270 degrees, there was a 10 percent change in the division's average personnel losses. This emphasizes the necessity for taking wind direction into account in planning a group nuclear strike with surface bursts. This is all the more so since modern methods and means of providing meteorological support to the rocket troops make it possible to forecast the average wind in enemy territory to a depth of up to 300 kilometers. The precision with which nuclear strikes are prepared influences the average troop losses mainly of those targets against which these strikes are directly delivered; the dominant factor in this case is not the effect of radioactive contamination of terrain but the effect of the main destructive elements of the nuclear burst (shockwave, thermal radiation, and penetrating radiation). However, if only the general outlines of the area occupied by the enemy grouping are known (8 = 0), and the aiming points are set uniformly for the whole area (taking terrain into account, of course), then effectiveness in destroying the grouping will not, for all practical purposes, depend on the accuracy of the preparation of the nuclear stri es. However, it must be taken into account here that a low degree of detection of specific targets of the grouping being destroyed will-have a considerable effect on the pattern of losses, since, in this case, destruction of personnel located in tanks, shelters, covered trenches and slit trenches will be extremely low. Thus, if 6 nuclear strikes of 100 kilotons each are delivered against an armored division in a concentration area, with a uniform distribution of aiming points, then compared to a fairly high level of destruction of personnel in motor vehicles and armored personnel carriers (about - 50 _ to_.6Q_-p_ercemt,) , losses of personnel in tanks will total only 10 to 20 percent. The efforts of reconnaissance means must therefore be directed in the first instance toward the detection of tank (self-propelled artillery) units and subunits. Only then can we count on the most effective utilization of nuclear warheads in a group nuclear strike, and on the sure destruction of these very units and subunits. Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 9 of 22 50X1-HUM A group nuclear strike using surface bursts against a large enemy grouping is prepared and delivered by decision of the commander of the army (front); on the basis of analysis of reconnaissance data concerning the enemy, the situation, the nature of the tasks to be carried out by his own troops, and an estimate of the capabilities of the rocket large units (units), he determines the required degree of destruction, the number of missiles and their yields for the group nuclear strike, and fixes the time of the strike. After the adoption of the decision for a group nuclear strike, the commander and staff of the rocket forces and artillery of the army (front) determine the coordinates of the aiming points and the sequence of the nuclear bursts, refine the estimates for the effectiveness of the nuclear strikes and for the safety of our troops, assign tasks to the commanders of rocket large units (units), and monitor the course of preparation for the strike. Let us dwell in greater detail on the methodology for deciding the most important questions involved in preparing a group nuclear strike. As an example, let us examine the destruction of an armored division in its concentration area, for which a variant disposition of combat units is set forth in Figure 1. The following conditions, which we regard as typical, are assumed here. The enemy will require at least one hour to evaluate the radiation situation after the strikes and to withdraw his troops from the areas of radioactive contamination; the combat effectiveness of units (subunits) of ours which have been subjected to destruction by nuclear weapons will be estimated by the enemy for 24 hours and more ahead of the moment of delivery of the nuclear strikes; troops will be withdrawn from contaminated terrain in motor vehicles, armored personnel carriers, and tanks, with the use of individual means of protection. In calculating the average personnel losses in each target (and the division as a whole), we used a method of statistical analysis based on a model worked out by Colonel S. B. Borshchevskiy. Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 10 of 22 50X1-HUM The effectiveness of destruction of an enemy grouping of forces is evaluated according to the number of combat units and subunits destroyed (losing their combat effectiveness). When surface bursts are used, however, it is fairly complicated to determine the estimated results of the destruction of each separate target. This can be done most correctly and accurately only with full detection of the grouping to be destroyed and with the use of computers. At the same time, we can recommend a less complicated method of estimating the effectiveness of surface nuclear bursts which is accurate enough for practical use. This method is based on the fact that if several nuclear strikes are delivered, and if the zones of destruction of the enemy grouping cover the area to a sufficient degree (40 to 60 percent and more), then the extent to which the area is so covered will coincide roughly with both the percentage of combat units (subunits) put out of action and the percentage of personnel destroyed. If 30 to 50 percent or more of the targets are known, the percentage of combat units (subunits) and personnel put out of action will be equal to or slightly greater than the percentage of the area covered by the strike, while if B = 0, it will be less by an average factor of 1.3. The graphs (Figure 2) set forth the average values for an area covered, taking into account the radioactive contamination of terrain for one surface burst. The graphs are drawn for fixed yields per nuclear warhead under the most typical conditions of personnel deployment. The vertical axis of each graph shows the average value for the area covered S 1 by one nuclear burst, and the horizontal axis the distance R from the aiming point along the axis of the fallout pattern up to the limit of the area occupied by the grouping. The curves correspond to the different types of protective cover of personnel. For a given type of personnel cover, and observing the distances recommended below between the axes of the fallout patterns from the radioactive cloud, the average value of the area covered Sn by several bursts is determined 5OX1-HUM according to the formula S = Si- + Si- + ... + S1 , (1) Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 11 of 22 Pages where S, S , ..., S} represent the average value of the area coveredn y the firs, second, ..., through the nt5oX1 HUM bursts. If the personnel within the grouping being destroyed are deployed in shelters of various types, the average area covered by the strike will be determined as the sum of the products of the proportion of personnel deployed in a given type of shelter multiplied by the average area covered by all bursts, to be calculated according to the formula (1) for the given type of shelter, i.e. S K S + K S + ... + K S n 1 nl 2 n2 n nn (2) S 11, Sn21 ..., S represent the average area covered' from all bursts for tie first, second, ... through the n type of personnel shelter; K1, K2, ..., K n represent the proportion of personnel deployed in shelters of different kinds.

As noted above, when 30 to 50 percent or more of the targets are detected, the percentage of combat units and subunits put out of action (Mb ) and personnel destroyed (M zh.s ) is taken as equal to :he percentage of area covered, while if the detection is near zero, it is taken as equal to the percentage of area covered reduced by a factor of 1.3. Example 1. Estimate the effectiveness of the destruction of an armored division, in its concentration area (when 0 = 100%), deployed over an area of 450 square kilometers (Figure 1), if it is planned to deliver 7 nuclear strikes against the following targets: the 1st Tank Battalion, 2nd Tank Battalion, 3rd Tank Battalion, 3rd Motorized Infantry Battalion, 4th Motorized Infantry Battalion, 6th Tank Battalion, and a Battalion of Honest John missiles; the yield of nuclear warheads is 100 kilotons each, surface bursts, and average wind direction (direction toward which wind is blowing) 225 degrees. Solution. The distance R is measured off on the map, followin g he average wind direction from the planned aiming points up to the borders of the area occupied by the grouping. The average value for the area covered by one burst S1 is then determined for these measured distances from thi graph (Sketch 2,a), and the average area covered Sn from all bursts is calculated according to formulas (1) and (2) using the coefficients in Table 1. The sequence of calculations is set forth in Table 2.

Figure 3 gives the size of the average area covered by one burst, in relation to the distance R, for various nuclear warhead yields and various large units of our probable enemy. From these graphs it may be seen that with surface nuclear bursts, the effectiveness of warheads with a yield of 10 and 20 kilotons is less by an average factor of 5 and 2.5, respectively, than that of warheads with a yield of 100 kilotons; consequently the expenditure of these nuclear warheads will be greater by the same factors. It is therefore inadvisable to use nuclear warheads of less than 20 kilotons in surface bursts; they can be used for aerial bursts against targets lying near the border of the area occupied by the grouping and not already covered by the zone of radioactive contamination of terrain. The procedure for solving the given problem is as follows: the required level of destruction of the enemy grouping Mt is established, after which the area which must be covered ~ith destruction zones Sn.tr is determined (taking into account the coefficient R9, which depends on the degree of detection of the targets within the grouping to be destroyed). In this we use the formula Sn,tr = K9Ntr Sn where S is the area occupied by the enemy grouping. n Since one of the accepted rules is a more or less uniform distribution of aiming points, we can assume that the sum of the distances from the aiming points to the border of the area of the grouping, divided by the number of aiming points, is approximately equal to the radius of a circle equal in area to the area of the grouping being destroyed, i.e. 50X1-HUM Rsr (3) Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP1O-00105ROO0100350001-7 Page 15 of 22 PACT OR 50X1-HUM According to the value of R s and the yield of the nuclear warheads which can be used to deliver the group nuclear strike, the size of the area to be covered by one nuclear burst Snl is found on the graph (Figure 3). If nuclear warheads of identical yields are used for the delivery of a group nuclear strike, the number of warheads equals N S f (4) If nuclear warheads of different yields are used for delivery of the strike, the number of warheads is determined by the fact that the area to be covered is equal in size to the area covered by the zones of surface nuclear bursts of different yields (for a given value of Rsr). Aiming points are designated in conformity with the recommendations set forth below, in which the aiming points for the lesser yields are designated closer to the borders of the area of the grouping from the downwind side. Example 2. Determine the expenditure of missiles for the destruct on of 60% of the combat units and subunits of an armored division, in its concentration area, deployed over an area S = 400 km 2, if only the area occupied by the division (i = 0, and I~ = 1.3) is known. The actual distribution of targets corresponds to Figure 1. To carry out this task we may employ six missiles, each with a nuclear warhead of 300 kilotons or six missiles, each with a warhead of 100 kilotons. Solution 1. We determine the value 400 11 Ian. R sr = s TT / -M. 2. From the graph (Figure 3,a) for R sr = 11 km, we determine the average area covered by one burst: for 300 kilotons--40 km2, for 100 kilotons--30 km2; using formula (3), we calculate the required area to be covered by destruction zones Sn,tr = 1.3 ' 400 = 310 km2 S n tr Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP1O-00105ROO0100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Page 16 of 250x1-HUM 3. In order to reduce the total number of missiles used for a group strike, we first make a calculation for nuclear warheads of greater yields (having in mind 6 missiles, each with a nuclear warhead determine their area of coverage of 300 kiloto ns and Sn=6 ? 40 = 240km2. 4. The difference between S n t and Sn is 310 - 240 - 70 km2. From formula '(1) we determine that to cover this area two more missiles are needed (70:30 2), each with a nuclear warhead of 100 kilotons. Thus the total expenditure comprises 8 missiles: 6 missiles of 300 kilotons each and 2 missiles of 100 kilotons each. The location of the chosen aiming points is shown in Figure 1, in which aiming points No. 7 and No. 8 are designated for the missiles with a nuclear warhead of 100 kilotons each. For comparison, Table 4 sets forth the results of calculating the average value of destruction of personnel for each target in a division (results obtained by the method of statistical analysis for an instance in which their actual disposition is known); the results also confirm the high accuracy of the proposed method of determining the required number of missiles (the average error in determining the effectiveness of destruction of a grouping does not exceed 2% in comparison with that Given here).

The general rules for determining the aiming points for a group nuclear strike are as follows. When the degree of detection of individual targets within t e grouping to be destroyed is sufficiently high = 30 to and morel, e centers of the most important targets are taken as the aiming points; first and foremost the centers of tank battalions, battalions of free-flight rockets and guided missiles, and divisional and brigade control organs (posts). If the position of individual targets is not known, the aiming points are chosen in areas (sectors) in which ese targets are most probably located on the basis of local terrain conditions. In both instances, it is advisable to distribute the aimin ints more or less uniformly over the entire area g destroyed. This will achieve surprise in use and, at ben the same time, the action of nuclear weapons on all the troops of the given enemy grouping. In order to keep from laying down excessive zones of radioactive contamination of terrain, the distance between the axes of the fallout patterns from the radioactive clouds of adjacent bursts must be at least 3 to 4 kilometers. To do this, the average wind direction must be taken into account. The timing of the nuclear bursts (in relation to each other) is determined by the staff of the rocket troops and artillery, in accordance with the established time frame for delivering a group nuclear strike. The launching time for each missile is set by the commanders of the rocket units (large units). In order to prevent failure of a warhead fuze device or premature initiation of the nuclear device (which may happen if a nuclear warhead passes through a radioactive cloud formed by a previous nuclear burst), it is advisable to deliver the strikes successively, beginning with the most distant targets, at an interval of one or two minutes. If the plan is for all nuclear bursts to occur simultaneously, Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP10-00105R000100350001-7 Declassified in Part - Sanitized Copy Approved for Release 2012/04/19: CIA-RDP1O-00105ROO0100350001-7 Page 18 of 22 Pages the distance between adjacent aiming points must be at least 5 kilometers for warheads of 100 kilotons and 6.5 kilometers for warheads over 100 kilotons. 50X1-HUM It has been noted above that, when surface nuclear bursts take place, there is formed, within a certain time from the moment of delivery of a group nuclear strike, a dangerous zone of radioactive contamination expanding beyond the limits of the area of the grouping being destroyed and drawn out for 100 to 150 kilometers and more in the direction of the wind. In negotiating this zone, enemy personnel may receive such doses of radiation as to significantly reduce the combat effectiveness of his troops. This is borne out by the following example. Let us suppose that one hour after the delivery of a group nuclear strike by eight missiles with a yield of 300 kilotons each, with surface bursts, an enemy infantry division whose personnel are predominantly in motor vehicles advances toward a zone of radioactive contamination 50 kilometers from the area of destruction. Under these conditions the division can begin to negotiate the contaminated zone (without exposing itself to a dose of more than 50 roentgens) only about 5 hours after advancing toward it. If the enemy nevertheless starts to negotiate this zone from the march, then, considering their means of transport (K 2), the personnel will receive a dose equal to 240 roll~gens. As a result, up to 15% of the division's personnel will be put out of action by the end of the first 24 hours. Research shows that the use of surface nuclear bursts with a yield of 100 kt and more, under conditions providing for the safety of our own troops, will be an effective means of destroying enemy groupings, of making it impossible for enemy troops to maneuver widely, and of delaying the approach of reserves and the bringing up of materiel. The methodology proposed in this article makes possible a quantitative evaluation of the effectiveness of surface nuclear bursts in order to provide an adequate basis 50X1-HUM planning their use in group nuclear strikes.
