PD544 Point Detonating Artillery Fuze for high explosive (HE), base bleed and rocket assisted artillery shells PD544 The PD544 is a mechanical point deto- penetration when the mode setter is set The fuze consists of the nating artillery fuze with super-quick and to “DELAY”. When not set to “DELAY”, the following major compo- delay functions. IDD provides a back-up function for the nents: SQ setting. It has been designed and qualified for • Upper fuze body use with 105 mm and 155 mm high • Lower fuze body explosive artillery shells, including exten- • Mode Setter ded range and base bleed ammunition. • Impact Delay Device The fuze is suitable for use with 39, 45 (IDD) and 52 calibre weapon systems and is • Safety and Arming safe and suitable for flick-ramming. The Device (SAD) fuze has also been designed and qualified • Booster assembly for use with 120 mm rifled mortars, providing full function at all charges including charge 0. The fuze design incorporates a fully Insensitive Munitions (IM) compliant firing train which provides enhanced safety during storage, transportation and operational use. Fuze arming is initiated by transitional and rotational forces after firing, with the fuze rotor moving in-line immediately after the muzzle safety distance has been achieved. The firing pin and SQ detonator assembly provide the super-quick action upon impact. The Impact Delay Device (IDD) is located in the rear part of the fuze and provides a 60 ms fuze initiation delay for target GmbH - *ld 07/16 Microtec Technical Data PD544 JUNGHANS © Muzzle safety ≥ 200 m (155 mm gun) JUNGHANS Microtec GmbH ≥ 150 m (105 mm gun) Unterbergenweg 10 Required setback for arming ≥ 850 g 78655 Dunningen-Seedorf Germany Max. setback 26,000 g Phone +49 7402 181-0 Required rotation for arming ≥ 2,900 rpm Fax +49 7402 181-400 Max. rotation 25,000 rpm JUNGHANS T2M SAS Storage temperature range -54°C to +71°C Route dÁrdon 45240 La Ferté Saint Aubin Operational temperature range -46°C to +63°C France Phone +33 2 3851-6422 Dimensions STANAG 2916 Fax +33 2 3851-6835 Weight 595 ± 20 g Shelf life 10 years www.junghans-defence.com Compliance with MIL-STD 1316E / STANAG 4187 Ed. 4, MIL-STD 331C / [email protected] STANAG 4157 Ed. 2 A Diehl and Thales company.

Guidance and control of artillery projectiles will be critical to future military operations. With the large quantities of unguided artillery shells stockpiled around the world, the course correction fuze could provide an attractive and cost-effective solution for munition control. This report proposes a drag brake and a spin brake course correction fuze concept, and compares their performance against the roll-decoupled four canard configuration. Specific guidance and control functions were designed and tuned for each using the 155 mm spin-stabilized artillery projectile as baseline. Dispersion sources included variations in muzzle velocity and gun’s azimuth and elevation angles relative to nominal conditions, and wind velocity perturbations. Monte Carlo simulations were performed to analyze the delivery accuracy. Results show that the drag brake concept compensates for muzzle velocity and longitudinal wind perturbations efficiently.

WORLD WAR Ii RESEARCH (1941-45) CHAPTER 'TI! ThE EVENT OF WAR" The second worldwide war was foreshadowed in the Japanese in of Ethiopia in 1935, and Hitler's march into the Rhineland in 1936. Isolated and safeguarded by successive Neutrality Acts passed in 1935, 1936, and 1937, which barred the sale of arms or munitions to any warring nation, America watched the piecemeal fall of small nations, Austria and Czechoslovakia to Hitler, Albania to Musso- lini. With the German attack on Poland in September 1939, Britain and France declared war against the dictators and World War II began. The first amendments to the Neutrality Acts were enacted. By temperament strongly neutral and still in the grip of depression, the Nation had willed belief in Chamberlain's "peace in our time" until shaken by the occupation of Czechoslovakia in the spring of 1939. But cer- tain of war and of America's inevitable involvement was the small band of foreign-born scientists, their spokesman Niels Bohr, who had recently arrived in this country. Shepherding atomic research here, Bohn at once urged restriction in all Allied countries of the publication of further data on the possibility of nuclear fission. Many individual scientists refrained, but control of publication in American scientific journals did not become effec. five until almost a year later, following Hitler's invasion of Denmark and Norway. The National Bureau of Standards, convinced by the physicists on its Advisory Committee on Uranium of the certainty of a general war, began to put its affairs in order. On September 1, 1939, the day Germany marched into Poland, and one week before the President declared a state of limited national emergency, Dr.

Falkland Islands landmine exploitation - March 2015 FALKLAND ISLANDS LANDMINE EXPLOITATION – MARCH 2015 This report and the associated exploitation work was funded by the United Kingdom of Great Britain and Northern Ireland. Background The need for exploitation1 was recognised early during the planning for mine clearance operations in the Falkland Islands. Little was known about the state of the mines some 30 years after the conflict, and it was considered important to understand the effects of ageing, along with the implications for issues such as appearance/recognition, functionality and detectability. Exploitation was previously carried out during clearance Phases 1 and 3. This report outlines the work conducted during Phase 4a, where samples of the following mines were examined: Type Designation Country of origin Number examined/tested P4B Spain 50 Anti-personnel (AP) SB-33 Italy 16 Anti-tank (AT) SB-81 Italy 12 Outline details of these mines are given in Annex A. A total of 78 mines and fuzes were examined or tested, with 38 mines being fully disassembled. Work was carried out by Colin King (herinafter ‘CK’), technical director of Fenix Insight Ltd, from 5 – 12 March 2015. Aim The aim of this report is to outline the findings from the exploitation work, with particular emphasis on: a.

To achieve these objectives, a standard charge is used that is capable of developing deto- nation pressure equal to 1 kg of TNT. 167 There are several types of explosives that can develop the appropriate detonation pressure. By knowing the detonation velocity and the density of a given explosive, the detonation pressure can be calculated (Chapter 2 - Explosives). INITIATING DEVICES Avalanche blasting is based on a nonelectric detonating system or systems that are not susceptible to initiation from the high static electricity that is prevalent in snowstorms and near ridge crests. Even with non- electric blasting caps, avalanche blasting should not be conducted when there is evidence of a strong static electricity field (cumulonimbus clouds, electric buzzing). Cap-and-Fuse - A cap-and-fuse assembly can detonate explosives that are sensitive to a No. 6 cap (Figure 11- 1). However, in severe winter weather, some primers with low proportions of sensitizers may require a No. 8 cap or larger. Blasting caps are susceptible to accidental ignition from excess heat, friction, or static electricity and should be handled with great care. Where adverse conditions are expected (static electricity), other tech- niques should be used or the blasting operation should be shut down.
