Contents includes maps of the Great Britain and Irelands plus an index to other map documents' TNA reference numbers starting with HO 193.

Content includes calculations for the 12 regions in the United Kingdom that the Bomb Census Organisation created to map the effectiveness of aerial bombing on those areas in regards to average dwellings destroyed and average casualties.

Hand written list of drawings and plans to bomb and fortification tests.

Class list of reports from 1943 with TNA reference numbers starting with WO 291. List includes TNA reference number, date, description and former reference number.

Extensive report on the damage of machine tools from high explosive (H.E) bombs. Includes methods of analysing damage and collecting data plus general damage reports on different types of machinery. Includes tables of data.

Report on the statistical data obtained from damage reports on machines from aerial bombing and how it is used. Includes "Methods of Computation" , "The correlation factor" , "The damage classification - its relation to effective area" plus figures and tables.

Brief on the damage on machinery and manufacturing plants sustained from aerial bombing. Very general information on how bombs can affect different machines.

Brief explaining the amounts of blast pressure exhibited by different bombs at different distances. Also lists injuries and fatal limits of blast pressure.

Note no. ARP.100/RJ. Report for the Ministry of Home Security. Summary of scaled tests to measure the penetration of the blast wave generated by a 500 lb. G.P bomb into different domestic surface shelters. Shelters were based on Type I of the A.R.P. Memorandum 14. Includes tables and diagrams.

Note no. ARP/108/RJ. Report for the Ministry of Home Security. Summary of scaled tests to measure the penetration of the blast wave generated by a 500 lb. G.P bomb into domestic surface shelters with multiple departments. Includes tables and diagrams.

Report on a scaled test to confirm the conclusion that the area of damage by blast per ton of charge will not continue to increase when the bomb size is increased beyond 4000 lb. H.C. Includes calculations.

Note no, ARP/144/HS. Report for the Ministry of Home Security. Incident reports on the aerial bombing of Ashley Walk and the measurements of blast pressures from the explosions.

Extensive report for the Ministry of Home Security - Research and Experiments Department. Extensive report detailing the common injuries caused by small explosive devices. Content includes "The Relative vulnerability of different parts of the body" , "Criteria of incapacitation for wounds caused by small splinters" , "The effective target size of the body for small splinters" , "The estimation of the standardised casualty rate of a bomb from data about fragmentation" , "The value of protective armor" plus appendices "Details of wounds caused by small fragments" , "Regional distribution of wounds, exposure factors, and relative vulnerability of different parts of the body; data mainly from 1914-1918 World War" , "The regional distribution and mortality of splinter wounds in air-raid casualties" , "The penetrative powers of steel balls and steel cubes in comparison with those of bomb splinters".

Brief on the safest way to clear the area around air dropped unexploded bombs so as to minimize casualties if the bomb were to go off. Data was gathered from over 300 incidents involving high explosive bombs recorded by the Casualty Survey. Incomplete document.

Brief detailing how the different standardised casualty rates are calculated. Rates included are vulnerable area, casualty risk rates and fatal casualties both hospitalised and non-hospitalised. Incomplete document.

Report on a series of model-scale tests carried out to obtain data on the effects of explosions below the floor slabs of surface or semi-sunk shelters to provide information upon which to base estimates on the relative vulnerability of field-defense structures against various forms of air attack. Includes tables, photographs and appendix: "Basic dimensions of enemy concrete surface shelters".
