Also, artillery may be employed for firing at technical positions and transport with nuclear warheads. Each one of the above targets has its own features and calls for an individual approach when working out recommendations for its destruction. Let us evaluate these targets from the viewpoint of their vulnerability to artillery fire. I Stipulated Target Zone (Dimensions) The full characteristics of the destructive action of shells on any target are based on the law of destruc- tion (zakon porazheniya), which establishes the inter- relation between the probability of target destruction and the distance of the burst from the target. .Never- theless, calculations based solely on the law of destruction are linked with certain difficulties. Therefore, as a rule, one of its characteristics is used in practice - the projectile moment of distribution (pulevoy moment raspredeleniya) - which is known as the "stipulated target zone" (privedennaya zona tseli). The stipulated target zone is a convenient and objective characteristic of the action of shells on targets. Physically, this is a conventional (uslovnyy) area of definite size, the probability of even one hit on which Is numerically equal to the probability of destruction of the target. -2- GROUP 1 Excludod from avtornoik downgrading and (b)(3) (b)(3) Approved for Release: 2020/03/03 C01166952 (b)(3) Approved for Release: 2020/03/03 C01166952 IRON BARK Each target has its own stipulated zone. The targets under review are by nature individual combined targets composed of elements of different vulnerability (equipment, projectile, personnel). This circumstance creates a certain amount of difficulty in finding a law of destruction for them. Moreover, finding a law of destruction, and therefore the exact size of the stipulated target zone for such targets as enemy offensive nuclear-weapons, is practically_impos- sible for the time being, in view of the absence of data of any kind on their vulnerability to artillery Shells. Therefore, one is obliged to use approximate characteristics obtained by indirect means. In such cases, the stipulated zone is also often calculated on the basis of logical considerations, without any knowledge of the law of destruction. We shall be using this method for certain targets in this work.: 1. Stipulated Zone of a Launching Mount (280mm Gun) Located at a Firing. Position (Sop) Launching mounts for "Lacrosse" missiles and "Honest John" and "Little John" rockets as well as 280mm guns occupy a firing position as a rule for one round, after which they move to a waiting position (cover). For this reason, as a rule firing positions are not equipped from the engineer viewpoint. As a target, a launching mount (gun) at a firing position is a mount (combat vehicle Or gun) in a loaded -3- GROUP 1 Extludo-d front automatic downgroding and (b)(3) -(b)(3 Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 7�tr"i3* -F"T� IRONBARKi state * located on an open site manned by a crew engaged in preparations to fire the round. The vulnerable elements of such a target are con- sidered to be: the projectile, the equipment of the mount (gun), and the crew located in the open (it is assumed that after the first bursts of shells in the vicinity, the crew will lie flat). The sizes of the launching mounts (280mm guns) taken from zi-27 are given in Table 29.

The loading of 280mm guns is done directly at the firing position, and for this reason, at the time of loading, beside the gun itself at the firing position there will be the vehicle with the shell. -4- GROUP 1 Excludod from automatic downgrading and (b)(3) (b)(3) (b)(3) Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 ellt=7.11fE�- 1RONBARK Up to now, the stipulated target zone of such a tar- get as an enemy launching mount (280mm gun) at a firing position was taken to be the geometric dimensions of the mount (gun), taking into account the shadow projection, increased by a'certain arbitrarily chosen radius of - fragmentation (blast) effect of the shell on equipment. In our view, the stipulated target zones obtained by such methods do not wholly reflect the capabilities of artillery shells in destroying enemy launching mounts (guns). Study of information available on launching mounts, as.wellas their ammunition, gives us ground to estimate their present vulnerability to shell splinters. It Would also be advisable to take into account the fragmentation action of snells on the crew (personnel) working near the launching mount (gun). Governed by the desire to make a fuller consideration of the destructive capabilities of artillery firing at enemy launching mounts (280mm guns) located at firing positions and lacking definite data on their vulnerability, the writers of this study decided to follow the course of using available data on the action of shells on tar- gets bearing most resemblance to the ones Under review. In particular, to determine stipulated target zones for "Lacrosse" gUided missiles and "Honest John" and "Little John" free rockets, we used results of experi- mental firing being carried out by the writers of study ipw, with the aim of determining the stipulated zone or a SON-4 radar set by experimental means. The stipulated zone for a 280mm gun was determined by using the coordinate area of destruction of a 152mm M-47 gun, obtained in study 4717. The reason for using the experimental data in study 217 to determine the stipulated zone for "Lacrosse" guTded missiles and "Honest John" and "Little John" free rockets is the fact that missiles and launching mounts can withstand roughly the same amount of frag- mentation and blast effect from a shell as the SON-4. This is shown in the following data. -5- GROUP Exciusbid from autotnotic down rodin clad Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 (b)(3) IRON IRONBARK (b)(3) It has been shown in study J7 that in order to put a SON-4 radar set Out of ac ionjit is essential for a splinter to penetrate the wall of the set and the wall of the cabinet (unit) containing the rad�o technical equipment. At the sane time the splinter should have a specific energy in the region ot ?00 kgm/cm4. There is every reason to believe that in Order to put a missile or a launching mount out of action it is necessary for a splinter to penetrate either the casing of the missile or the balancing column (urav- noveshivayushChaya kolonka), and in the vase of the "Lacrosse" the wall of the automatic checkout apparatus (electric power unit). Note that the main part of the vulnerable surface is the surface of the missile. There is no information on the casing thickness of "Lacrosse," "Honest John," and "Little John" missiles. Comparing them to similar missiles produced here at home, it may be assumed that the thickness of the casing of an "Honest John" should be in the regionci 8mm and that of the "Lacrosse" and "Little John" should be in the region of from 4 to 6mm44rovided the missile is made of steel of medium hardness. Naturally, if they are made of harder steel, the thickness of the casing. may be re- duced. -Rockets (missiles) are of cylindrical shape. The amount of energy of the splinter required to penetrate a cylindrical surface will be greatly influenced by the angle of impact (vstrecha) of the splinter with the obstacle. We shall consider the angle of impact to be the anglesebetween the tangent at the point of impact of the splinter with the obstacle and the direction of flight of the splinter. The maximum angle of im- pactivmay be taken as 400.

Having-got this data, and using the corresponding coefficients which allow one to convert from the conditions under which S'c was obtained to conditions of firing at launching mounts, it is possible to cal- culate the respective stipulated zones.

It should be noted that the stipulated zones which were obtained did not take into consideration the effect of fragmentation on the crew. MOreover, the effect of ricochet splinters capable of leaving scratches and dents on the surface of the missile were ignored, as were their effect on �the tail assembly, stabilizing fins, and the launching mount. For this reason the stipulated zones obtained can be only underestimated. At the same time, the calculation of the change of width of the vulnerable part of thecylindrical sur- face; depending on the distance of the burst from the launching mount, was carried out roughly, and this could have led to a certain overestimate of the results obtained. On the whole, though, the stipulated zones shown in Table 34 indicate approximately the true nature of the destructive effect of shells on enemy mounts located at firing positions. In determining the stipulated zone for a 280mm gun located at a firing position, use was made of the co- ordinate (koordinatnyy) law of destruction of a 152mm M-47 gun located on an open site and which was obtained from 017 for conditions when firing at the gun arid at the gun crew, located near the gun in kneeling position (the stipulated zone of a rifleman in kneeling position) is carried out by a 122mm shell by direct laying (the angle of descen4-30). The analysis of the nature of this law made it possible to determine the part played by the destructive effect of a 122mm shell on certain vulnerable elements of the target when the shell hit the stipulated target zone, and in particular the part played by the frag- mentation effect of the shell on the equipment and the crew. In other words, if S'op is the dtipulated zone for a 152mm gun located at au�open firing position, it has been possible to determine its components: -15 (b)(3) GROUP Erich/clod from automatic downgrading ond duclassificorion (b)(3) Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 vezw-zz (b)(3) IRONBARki S' = Smch op ' S'o/mch So/r where S'mch is the part of S'op equal to the area occupied � by the gun; S't is the part of S'op equal to the shadow projection of the gun So/mch = 65 m is the part of S'op that coincides with the fragmentation action of the shell on the gun equipment, And S'o/r = 55 m2 is the part of S'op that coincides with the fragmentation action of the shell on the crew. Having this data and using the appropriate coefficients which make it possible to change over from conditions in which the S',010 was obtadlipd to conditions of firing at an enemy 280m1ir gun, it is possible to calculate the corresponding stipulated zones. The formula for the approximate calculation of the stipulated zone (80p) for a 280mm gun located at a firing position looks-as follows: S0p = Smch St +0Sio/mch +X/Sfo/r where, by analogy with formula (19)- Smch is the area occupied by the 280mm gun while St is-tte stipulated dimensions of the shadow projectirm of the gun: )e is the coefficient which takes into account the change in the effective fragmentation action of the shell on the crew and equipment when converting from conditions at which the law was obtained (122mm shell O - 30) to the effective conditions (caliber of shell different from 122mm, ec )4 30).

Nonethe- less, it is difficult to express in figures the ratio .between the vulnerable surfaces of a 280mm gun and that of a 152mm gun.

The firing position of a 203.2mm howitzer battery is equipped in the same way as the firing position of an ordinary battery. As a target, a battery of 203.2mm guns located at a firing position represents 4 guns locat- ed in full-section pits (okop polnogo profilya) with per- sosnel (crews) either in shelters or inside the pits.

Stipulated Zone of a Launching Mount (280mm gun) Located at a Waiting Position Launching mounts and 280mm guns at waiting positions, as a rule, are located in an open pit of limited size, ' ensuring protection for the vulnerable parts of the mount (gun) and projectile (if the mount has the projectile at the waiting position from the fragmentation effects of a close shell burst. Because 280mm guns and "Little John" launching mounts are located in pits to- gether with their prime movers, the pits are naturally meant to shelter the prime movers as well. This requirement is met by a pit whose depth is approximately equal to one half to two thirds of the height of the launching mount (gun). The part of the launching mount (gun) which is above ground level, will be sheltered by the parapet. The personnel at waiting position as a rule are located in shelters. Therefore the vulnerable elements of such a tar- get as a launching mount (gun) at a waiting position are the mount (gun) equipment and prime movers located in pits, as well as personnel who for some reason are not using shelters.

Stipulated Zone of a Launching Mount (280mm Gun) on the March The launching mount for "Lacrosse" missiles or "Honest John" rockets are individual combat vehicles which can move independently, whether with or without the migbile or rocket. The launching mount for the "Little John" rocket is towed by a prime mover when changing position. It may also be armed with a rocket. A 280mm gun on the march is a train made up of two prime movers with the gun between them. The dimensions of the mounts (trains)were given previously. As a rule, the mount or gun crews make the move on a separate vehicle (vehicles) following at a con- siderable distance from the mounts (guns). Vulnerable elements of a target such as a launch- ing mount (gun) on the march are the mount (gun) equipment and traction equipment located on the open road, as well as those personnel who accompany the mount (gun) and are in the Cab. Launching mounts with "Lacrosse- missiles or "Honest John" rockets on the march, by their nature, differ .little as targets from when they are located at a firing position and, for this reason, allowing for a certain amount of error, the stipulated zones of these mounts on the march are taken as the same as in the case of their being located at a firing position The stipulated zones that represent 27?.7 them located at a firing position, increased by the area and shadow projection of the prime movers, are also taken to serve as stipulated zones for a mount with a "Little John" rocket or a 280mm gun on the march L17.

Therefore, the stipulated zone for transport carrying nuclear ammu- nition (Sir) can be taken as that of the corresponding mount witE7missile, when located at a firing position. 6. Stipulated Zone of a Technical Position A technical position as a target is a camouflaged site of limited area at which are located in pits vehicles With special equipment for checking out the body and nose cone of the missile (rocket), assembly, and transfer to thelauncting Mount or transport (carrier). To carry out some of these operations, at least two special vehicles must leave the shelter and park near the launchd.ng mount (transport). At that moment the technical position becomes most vulnerable to artillery fire. The vulnerable elements of such a target are: the missile, the equipment part of the special vehicles, and the launching mount (transport), as well as the personnel working near the vehicle. * Nuclear ammunition for 280mm and 203.2mm guns is carried in a vehicle which it is practically impossible a7 to distinguish from conventional ones.

Ammunition' Expenditure Norms Artillery fire for effect at enemy offensive nuclear weapons is delivered with the aim of either destroying or neutralizing them. The determination of the task of fire for effect at a certain target is shaped by a number of factors and in particular by the future 1/7 operaticnsof one's own troops, the nature, range Z/7 and (two words illegib147 of the target, the possibility of employing offensive .nuclear weapons against them, and the time of their readiness, the quantity and quality of our artillery and availability of ammunition,. and the precision of determining target coordinates and settings for fire for effect, etc. 1. Fir- for Destruction The destruction of an enemy launching mount (gun) at a firing (waiting) position or on the march, as well as the destruction of a technical position or transport with nuclear warheads, lies in depriving the target of its combat effectiveness for the time necessary to replace or repair the equipment of the launching mount (missile, gun, or special vehicle) and replace (reinforce) the crew.

The expenditure of ammunition indicated in Table 38 may be substantially reduced by using chemical shells at the beginning of the fire concentration. According to � , the actton of one KhS0 shell with R-35 11 during the first fire concentration is equivalent to: (a) 1.5 high explosive fragmentation shells (granata) when firing at personnel in the open (when firing at launching mounts and guns in firing positions, as well as at technical positions). (b) 4 high explosive fragmentation shells w en firing at personnel in trenches, dugout shelters, tanks, and armored personnel carriers (when firing at launching mounts in waiting positions and on the march as well as at a battery of 203.2mm guns). Fire for destruction of targets is delivered by continuous fire concentration until the norm of shells ensuring their destruction has been expended. Fire concentration on the targets starts when all, or the greater part of batteries being employed for firing, are ready, in certain very urgent cases as each individual battery is ready. Batteries called upon to fire for destruction deliver fire at maximum rates. -3 5- 0110UP 1 Extlysied 4,a, otone$;,-. tkrirmgrwj.,.v nad (b)(3) (b)(3) Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 (b)(3) When necessary, a check is carried out on the accuracy of fire of each battery during the fire concentration. 2. Fire for Neutralization As previously stated, enemy offensive nuclear weapons are combined targets. One of the elements of any of these targets is the personnel looking after the equipment: the crew which prepares the mount (gun) for firing at the firing position or is located in shelters when the mount (gun) is at the waiting position; the detail (komanda) (part of the crew) accompanying the mount (gun) or transport with nuclear, ammunition on. the march; finally, the detail working at the technical position. By means of artillery fire, it is possible to create such conditions that the target will.temporarily lose its combat effectiveness * as a result of the personnel not being able to service the equipment. Neutralization of a launching mount (gun) at a firing (waiting) position or on the march, as well as neutralization of a maintenance position or transport with nuclear ammunition, consists in making the target lose its combat effectiveness for a period, ensuring the possibility of bringing up other, as a rule nuclear,. weapons for its destruction. Neutralization is achieved by creating conditions under which it is impossible for the personnel to carry out their duties at the guns (vehicles), as well as by passing (poputnyy) damage to equipment (vehicles). * We mean by loss of combat effectiveness a situation in which: firing tannot be carried out from the launching mount (gun); the launching mount (gun) is not capable of leaving the/Orattihg position or carrying out a march; work cannot be carried out at the technical position. -30- � GROUP 1 Exclud�d from owtoinati� downgrading or.d dodowiko�Ww Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 273reiziET (b)(3) FIRONBARK 1 Neutralization of the enemy offensive nuclear weapons that have been enumerated is thus linked with the capability of hitting the crew members (teams), while they are carry- ing out duties at the launching mounts (guns, vehicles) when they are (should be) out of the shelters, in positions similar to those of riflemen standing upright. � Stipulated zones of fragmentation effect from ground bursts on riflemen standing upright * taken from work Mand recalculated for conditions of fire with the most suitable charges are given in Table 39.

The duration (period) of neutralization iS estimated Et-wo words missing7 of such intervals. The effectiveness of fire for neutralization (probability of hitting a crew Member) remains constant during the whole period of neutralization. The possibilities of firing a round, and therefore the magnitude of the time interval t, will depend on the state of readiness for firing at which the mount_ (gun) was caught by the shelling. If one takes the worst case (the mount. or gun was subjected to neutralization at a time when all' basic preparatory operations for firing the round had already been carried out), the time interval t will be a Minimum one and, depending on the type, of mount (gun), will amount to from one to .several minutes. Confining ourselves to this worst case, we will- take the time interval t to be equal to 2 minutes and to be identical for all types of mounts (guns). We shall also reckon that the time required to move the mount (vehicle) from the zone of shelling will amount to not less than 2 minutes, and for this reason we shall take the size of t in these conditions as well to be equal to 2 minutes. We shall take the value P - 20 percent as a level of indication of effectiveness of,fire for neutralization, that is, the level of probability of striking every gun crew member while it is trying to fire a shot (trying to move the vehicle from the zone of shelling). On the basis of experience during the war the value 20 percent should be considered quite /1/ adequate for reliable neutralization of a target. -38 GROUP 1 Excluciod from automatic downgrading and declassification Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 IRON BARK The expenditure of ammunition ensuring neutralization of a target for a period of a 2 minutes is calculated according to formula (25) when Li-wo words missing7 (equal to P - 20 percent and Sts is taken from Table jine word missinE7 of MT-ells, calculated in such a way, . taking into account E.45:ne word missing7 the constant reliability of neutralization during the period /77 of neutralization, it is advisable to change over to the expenditure -o-ne word missing7 per minute, which is shown in Table 40. -39- s-E-e-fH.-T-- GROUP 1 Excludad front automatic downgrading and declanification Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 � wan r 1 IRONBAR"q laulc qu Zeute to Neutralize Enemy Offinsive Nuclear Weapongading probably reads: Expenditure of Shells in One Designation & character of target 7 Means of determining settings for fire for effect Lt7 and co- ordinaten of target Trty. systems Range WO 8 10 121 161 20 144!26 "--g 1 r 2 4 ---L- ---t7 D------0�. , ! 1 , "Lacrosse" guided Full preparation with inclusion of correct- 130mm Gun 7 .- 9 : 11H 13 I 18 18. missile, "Honest John" ions obtained by means152mm of a radar set; target Gun 5 8 10! 12 and "Little coordinates determ1ned122mm How, 6 8 10 John" free by air photo rockets i_ 152mm How 4 6 6 . 280mm /77 gun or'203.2 11411 A7 gun at the firing Same, target co- ordinates determined 130mm Gun16 18 18 19 20 21 position in a waiting by means of a radar set 152mm Gunll 15 17 17 - position & on the march. 122mm How 6 8. 9 Technical position & transport with nuclear ammu- nition 152mm How 4 6 - 6 -40 - SE-C-RET-- GROUP I Excluded from automatic downgrading and declassification Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 SftEf (b)(3) I IRONBA'RK Table 40 continued (b)(3) r 1 2 r----3---- 4 ' 6 r 1 8 9 ! 10 � � n11 preparation with inclusion of corrections determined by aid of aircraft; target co- ordinates determined by the aircraft 130mm�t7 Gun 152mmZU Gun ? 6 8 9 10 Adjustment of fire with aid of aircraft 130mm Gun 152mm Gun 4[ - 7 8 8 9 (10 10 Adjustment of fire with aid of a helicopter 130mm Gun 152mm Gun 3 8 12 12 17 16 20 122mm Ho* 4 7 9n7 -''152mm How Adjustment of fire with aid of a radar set 130mm Gun 152mm Gun 19 13 19 16 20 18 21 18 22 22 122mm How 9 12 13 152mm How 7 9 9 -41- GROUP I Excluded horn outornotie downgroding and declossicurtion (b)(3) Approved for Release: 2020/03/03 C01166952 Approved for Release: 2020/03/03 C01166952 [IRONBARK1 Let us examine separately the neutralization of a battery of 203.2mm guns. We know that a battery of 203.2mm guns by its nature differs little as a target fror4 an ordinary battery. For this reason, generally speaking, its neutralization should not differ in practice from the one worked out by practical experience for ordinary batteries. Bearing in mind that these batteries may have nuclear ammunition, it would be adVisable to work out stricter requirements for their neutralization, that is to increase somewhat the degree of destruction and limit the period of neutralization. If in the case of conventional batteries being neutralized the degree of destruction is taken to be equal to Psr = ?? percent and the period of neutralization on average-Wmounts to one hour, then in our view, when neiltralizating batteries of 203.2mm howitzers we should aim at a degree of destruction of Psr ?? percent (K, - 10.0?), and limit the period of neutralization to'30 minutes.

(b)(3) (b)(3) 1. Artillery can be employed both for the neutraliza- tion and destruction of enemy offensive nuclear weapons. 2. Fire for neutralization is delivered by continuous fire concentration up to the moment of a nuclear strike against the target. The shell expenditure to neutralize a battery of 203.2 mm guns is given in Table 41; expenditure of ammunition per win- ute to neutralize other enemy offensive nuclear weapons is given in Table 40: � Neutralization of any target can be carried out by a single battery, or two at a maximum. � 3. Fire for destruction is delivered by continuous fire concentration up to the full expenditure of the norm of shells shown in Table 38. To destroy individual mounts of "Lacrosse" prided missiles and "Honest John" free rockets at firing positions and on the march, as well as technical positions, when firing at medium arAd extreme ranges, 5 to 20 minutes will be required if fire for effect at the target is carried out by two batteries and 3 to 15 minutes if a battalion is called upon to deliver fire. To destroy "Little- John' free rockets, 280 mm and 203.2 mm guns at firing positions, as well as 280 mm guns on the march, by two batteries, 18 minutes to 1 hour 40 minutes will be needed, and by a,battalion, from 10 minutes to 1 hour.
