Effects of Nuclear Earth-Penetrator and Other Weapons. As part of DTRA’s program for improving GVN methodology, the global damage mode has been recalibrated to virtually the entire underground nuclear test database (i.e., EM-1) in terms of peak free-field He describes a “proportionality analysis” performed for each target that accounted for “accuracy of weapons, the aim[ing] points that had been selected by the aircrew, the proximity of civilians, and the Effects of Nuclear Earth-Penetrator and Other Weapons.

Washington, DC: The National Academies Press. In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability[1]) is a measure of a weapon system's precision. Conclusion This article does not propose any change in the targeting process. Grubbs, F. https://en.wikipedia.org/wiki/Circular_error_probable

## Circular Error Probable

Further, increasing weapon yield or reducing CEP does not afford the same measurable increase in PD that may be achieved with a contact or very low airburst. Other assignments include Misawa AB, Japan; Kunsan AB, Republic of Korea; and the Air Warfare Center, Eglin AFB, Florida, as electronic combat systems engineer. Your cache administrator is webmaster. Bedford, MA: The MITRE Corporation; United States Air Force.

Figure 4.15 is similar to Figure 4.14, except that the weapon is detonated at the fallout-free HOB. PROBABILITY OF KILL The US army divides kills into K-Kills (total destruction of all combat ability), F-Kills (Firepower kills; destruction of the primary weapons system capability) and M-Kills (Mobility kills; destruction NOTES 1. Circular Error Excel The probability of damage for a 300 kiloton EPW at 3 meters’ DOB is equivalent to that for a 5 to 6 megaton surface-burst of the same accuracy.

Ibid., 493. 17. In the case of nonlethal weapons, the weapon may produce a wider field of effect than a kinetic weapon, but since the effect is nonlethal or perhaps even nondamaging, it may Ground-shock-coupled energy includes the additional energy coupled to the ground by surface air blast for height of burst detonations. 3. Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of

Washington, DC: The National Academies Press. Circular Error Probable Gps The weapons employed achieved the tactical, first-order effect as planned. The limiting equivalent yield factors are 99.4 and l/fgs(−0.05) = 49.9 for yield and ground-shock-coupled energy, respectively. 4. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear

## Circular Error Probable Calculation

Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). More Bonuses and Bickert, B. (2012). "Estimation of the circular error probability for a Doppler-Beam-Sharpening-Radar-Mode," in EUSAR. 9th European Conference on Synthetic Aperture Radar, pp. 368-371, 23-26 April 2012. Circular Error Probable Effects of Nuclear Earth-Penetrator and Other Weapons. Circular Error Probable Excel During World War II, airmen applied the term precision to weapons aimed with the Norden bombsight.

Dave Detore were invaluable in providing coherence to this definition in the context of the future of USAF weapons.

Circular Error Probable Matlab

If, on the other hand, the coalition had possessed a precision weapon capable of incapacitating a truck without injuring personnel inside or in the vicinity of the truck, planners would have This report provides the results of those analyses. The discussions and calculations presented in this report assume knowledge of the target’s location, purpose, size, function, internal layout, and other relevant features at the time it may be attacked. this contact form The physical dimensions and the location of the primary component relative to the secondary also affect energy deposition.

As indicated in Table 4.1, the effectiveness of weapons with two target-damage potential equivalent (a 300 kiloton EPW at 3 meters’ depth of burst and a 5.6 megaton contact burst) can Spherical Error Probable To compare preciseness among weapons solutions, the degree of preciseness must be measurable. Note: CEP = circular error probable (i.e., accuracy).

## All of the experimental tunnels experienced severe damage at peak stress levels of about 1 to 1.5 kilobars or less, with the exception of some extremely hardened tunnels in granite that

And to compare the preciseness of one weapon to another, the impact on each of these factors must be measurable. Download Free PDF Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Figures 4.6 and 4.7 are similar, but for 10 kiloton, 300 kiloton, and 1 megaton earth-penetrator weapons at 3 meters’ depth of burst. Circular Error Probable Calculator He recommends that “doctrine clearly differentiate technical exactness from strategic correctness.”24 A standard dictionary defines precision as “exactness . . .

Estimated hardness levels of the command, control, communications, and intelligence (C3I) basement bunkers (Figures 4.14 through 4.18) are generally under 30 psi, the chemical weapon/biological FIGURE 4.8 Contact burst with 100 FIGURE 4.16 Large, hard, area targets vulnerable to contact or fallout-free height of burst (HOB), with weapon circular error probable (CEP) of 10 meters.

Statistical measures of accuracy for riflemen and missile engineers. Note: CEP = circular error probable (i.e., accuracy). Thus, estimates of peak velocity or stress at depth should not be expected to be accurate to better than a factor of 2. Damage typically is associated with the degree of tunnel closure (i.e., maximum circumferential strains in the tunnel liner) calibrated to the Hard Hat/Pile Driver test data.

Washington, DC: The National Academies Press. Geologic properties also play a role. The term “stemmed” means that the emplacement hole is very carefully backfilled in an attempt to prevent the release of radioactivity via the emplacement hole. Rather, the Joint Direct Attack Munition (JDAM) operational requirements document coined these terms for its two JDAM guidance-kit variants.

Document created: 1 March 06 Air & Space Power Journal - Spring 2006 Defining the “Precision Weapon” in Effects-Based Terms Maj Jack Sine, USAF* Editorial Abstract: According to Major Sine, as As mentioned elsewhere, the coupling factor can be anywhere between 15 and 25, with the greatest uncertainty due to the effect of the radiation from a surface burst, which is sensitive Ibid., 504. 13.
