Fuzes, list

The types of fuzes listed in Ref 20a, pp 258-59 are evidently obsolete. Unfortunately no drawings of mechanisms of recent VT fuzes are given in Ref 52, but just external views... 

Tail Fuzes AN-M100A2 and the other thirteen fuzes listed in Ref 51a, p 4-35 are vane-armed and inertia-fired. Arming is mechanically delayed by reduction gearing. When issued the fuzes are equipped with either a nondelay or a 0.025-sec delay primer-detonator M14, which can be... 

Besides the above tests there are about 90 tests for fuzes listed on pp D1098 to D1103-L and al so 45 refs are listed on pp D1103-R to D1107-L of Vol 4of this Encycl... 

Fuze. A list of various fuzes and description of some of them are given in Sections 5 Sc 6 in this Volume... 

Length of complete round with fuze 34.15 inches, maximum muzzle velocity 1700-1800fps and max range 328 yds (300 meters). Its propellant chge consists of 3.1 lb of proplnt M30A1, which is a modification of triple-base proplnt M30 listed in Vol 2 of Encycl (Ref 48) p C34, Table V (Ref 52 and its Appendix, pp 2-112 2-113) Ammunition for 37-mm to 105-mm inclusive is either "fixed" or "semi-fixed (See Ref 43, p A385-L). Ammunition of larger caliber can be either "separated"(such as... 

Part D, give cutaway views of typical 57, 75, 90, 105 106-mm recoilless rifle ammunition Fuzes used in recoilless rifle projectiles are listed in Section 5, Part C, item f... 

Fuzes used in mortar projectiles are listed in Section 5, Part C, item g... 

Priming charges are the same as listed under Stab Fuze Primer, while Tetryl, PETN RDX are used as the base charge... 

Besides fuze primer compositions OS 866 Fulminate Mixture (Navy), FA70 Wet Mixture (Army and Navy), and New No 4 Mixture (Army) listed in Figs 3-5, 3-6, 3-7, 3-8 8c 3-9, (our Figs 1-38 to 1-42 incl) the following mixtures were also used (Ref 23, p 2- 10) ... 

For example, "Electric Delay Fuze Primer Mkll5 " listed in Ref 23, p 5-50 and shown here as Fig 1-62, contains, among other ingredients, a base charge and there is no reason (in our opinion) why it should not be called detonator. 

Before proceeding to describe typical fuzes, there are listed in alphabetical order various fuzes. The following references were used as sources of information Ohart (Ref 17, pp 125-26), Glossary of Ordn (Ref 38b, pp 125-29) and MIL-STD-444 (Ref 40a, pp 75-82)... 

Fuze, PD M557- It is essentially M48A3 fuze assembled with booster M125A1. It is described in Ref 52, pp 5-45 to 5-47 and its drawing with list of parts is given in Fig 1-86. 

Fuze, PD XM593E. It is similar to XM593, described above, except there are some improvements which are listed in Ref 52, p 5-51. No drawing is given there... 

Locations of some of these fuzes in recoilless rifle projectiles are shown on Figs 45, 46, 47, 48 49 in Section 3, Part D Types and calibers of projectiles used in recoilless rifles are listed in Section 4, Part B, item b)... 

German. A detailed description of artillery fuzes (Gessosszunder) is given in TM 9-1985-3 (1953), pp 547-608 (listed here as Ref 27b) and this report and some other sources were used in compiling PATR 2510 (1958) (listed here as Ref 35), where... 

Japanese Artillery Fuzes. The following types are listed in Ref 28b, pp 391-426 St 518-43 ... 

A table listing some Russian artillery fuzes used during WWII is given in Ref 31, pp Rus 7 Rus 8... 

About 14 types of nose fuzes (of which 4 types are VT fuze) are used in GP bombs, old series, in addn to 8 types in tail fuzes New Series GP Bombs are not listed in Ref 44, but two of such bombs 750-lb Ml 17 and 3000-lb Ml 2 8 are described in Ref 51a, pp 2-26. 2-27. They are designed for high blast effects and for improved aerodynamic performance accuracy in flight when released from most altitudes and airspeeds. Their bodies are cigarshaped with a conical fin-assembly bolted to the rear. This can be seen from Fig 2-5. The Fig 2-20 of Ref 51a showing their cutaway view is not reproduced here because its lines are too faint to understand the inside construction... 

MT Tail Fuze M152A1, briefly described in Ref 5 la, p 4-77 without giving its cutaway or outside view, is designed for use in clusters only. Except for some details, the fuze is similar to AN-M145A1 listed above and in Ref 51a, p 4-71... 

While only three models of the bar-type and one of the ring-type have been standardized, addnl experimental models have been issued. A list of current US VT fuzes giving their applications in various bombs is in Table 4-20, p 4-87 of Ref 51a... 

TM 9-1985-5(1953) Army projectile fuzes (pp 391-426) Navy projectile fuzes (pp 518-43). They are listed in Section 5,... 

Italian Detonators, p 132 Types M Cortese, MlO (Allegenti) and M10 Italian Projectile Fuzes are listed in Section 5, Part C, under "Foreign Artillery Fuzes of WWII"... 

Determination of moisture content is described in Section 8, ANALYTICAL PROCEDURES, ETC", where are listed numerous US Military Specifications. These specs contain also a brief description of required physical tests. Before describing the specification requirement tests, a resume is given of "Measuring Techniques" of fuze explosive components, as discussed in NOLTR 1111(1952), pp 9-1 to 9-56 (Ref 11) The mea surement of fuze component performance consists mainly of a determination of (a) the input characteristics, and (b) the output characteristics...
