General purpose bomb

During the Vietnam conflict, the USA utilized Minol II in general purpose (GP) bombs, and encountered a milder form of spewing which was... 

Uses. Minols have historically been used in four types of ordnance, a) underwater (mines, torpedoes and depth charges) where the confinement of water offsets some of the loss of detonation velocity, b) blockbuster bombs in which a sustained and powerful impulse is more destructive than a high peak press, c) concrete fragmentation bombs where the high impulse will impart a satisfactory fragment velocity but will not pulverize the concrete they contact on impact, and d) in general purpose (GP) bombs...

According to the Technical Manual published in 1966 and listed here as Ref 51a, the new classification of US bombs is as follows 1) Semi-Armor-Piercing (SAP) 2) Fragmentation (Frag) 3) General Purpose (GP) 4) Incendiary (Inc or I)... 

A brief definition of general purpose bombs, when they were considered as one of the types of demolition bombs" was given in Ref 44, p B228-L. Another type of "demolition bomb" was LC (light case), of which the heavy (4000-lb) bomb was called "blockbuster "...

The US Air Force formulation designated as AFX 644 (based on TNT and NTO and also referred to as TNTO IV) is used for low-vulnerability General Purpose (GP) bomb. AFX-644 is a melt-cast, wax desensitized nitrotriazolone (NTO)-based explosive formulation which employs TNT as an energetic binder and aluminum powder to enhance blast performance. TNT, NTO, wax and A1 powder are mixed in proportions of 30,40,10 and 20% respectively and meets the United Nations ...

In tests (Ref 30) to determine the effect of liners and coating on the sensitivity of 50/50 Pentolite charges contained in bombs it was concluded that very little effect was obtained with a wax coating on the inner surface of the bomb, but an asphalt dip reduced the detonations considerably. The tests conducted were rather limited in the variety of waxes tested. Subsequent tests in 100-lb bombs were somewhat inconsistentwith the initial finding. Seven hundred-fifty lb general purpose bombs loaded in the 1970 s did use both a nose pad and liner of a bituminous material... 

Bombs, Antitank(AT). These were Brit bombs(there being no special US bombs) designed to be used against tanks or other armored vehicles. Probably general purpose (GP) bombs were more suitable as A/T than other types... 

Bombs, Demolition. Former classification for bombs that exploded after short penetration, accomplishing damage and destruction by both blast and underground explosion. A demolition bomb of WWII had a charge approx equal to 50% of the bomb s total wt. The present classification of such a bomb is GP(general purpose).

While traditionally general purpose bombs (GP bombs) are filled with sensitive tritonal (80% TNT, 20% A1 powder) or H6 (44% RDX NC, 29.5% TNT, 21% A1 powder, 5 % paraffin wax, 0.5 % CaCl2) and do not pass all IM requirements, PrNQ may emerge as a novel ingredient (melt-cast) for IM formulations for use in GP bombs. 

The most important parameters for the characterization of the performance of secondary explosives for use in energetic formulations in war heads and general purpose bombs (GPBs) are the heat of detonation (Q), the detonation pressure (p) and the detonation velocity (D). For comparison, Figure 9.11 shows a summary of the important values for aminotetrazolium dinitramide (IIAT I)N ), diaminotetrazolium dinitramide (HDAT DN ) and RDX.
