Frag Bomb

90-lb Frag Bomb M82, is constructed of square, steel wire, spirally wound on a seamless steel inner tube, as shown in Fig 2-2. A rounded nose piece housea the nose fuze, and a box-type fin assembly is attached to the tapered aft end of steel tube by a fin lock nut. The steel wire is forged at the nose and at the tail to form a solid body. The bomb can be used either in single suspension or in clusters (such as M27A1) 

When adopted for single suspension (by suspension lug welded to the body), only instantaneous or VT fuzes are used, but fitting of a mechanical time fuze is permitted with the addition of an adapter-booster. Its body diam is 6.06-in, length (with fin assembly M101) 28.0-in, total weight 86.6-lb (when loaded with. 11.4-lb of Comp B), or 87.4-lb (when loaded with 12.3-lb of TNT) 

260-lb Frag Bombs AN-M81 and AN-M88, (shown here in Fig 2-3), are similar. They are constructed in the manner described for the 90-lb Frag Bomb, except that they use 

Ml88 (VT), M163, M164 or M165- They also have used tail fuzes AN-M100A2, AN-M175 M172 (Ref 51a, pp 2-14 to 2-18) 

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

Its body, constructed in the same manner as described below for 90-lb Frag bomb, has diam 3.64-in. Its overall length is 22.4-in, and total wt ca 19.75-lb which includes either TNT (ca 2.7-lb) or Amatol (ca 2.6-lb). 

Fragmentation Bombs are described in Vol 4, pp D933 to D935- One of such bombs, 90-lb Frag Bomb, M82 is shown in Fig 2-2 on p D935... 

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)... 

This VT fuze can also be used with any GP, Frag or Chem bomb weighing 100-lb or more which takes nose fuze AN-M103A1 (shown in Fig 4-1) or M163- The nominal MinSAT of this VT fuze is 3600-ft. It is extremely sensitive and its tactical use is independent of height of release, speed of aircraft or type of terrain (Ref 51a, pp 4-88... 

Nose Proximity Fuze M166E3 is a bar-type and is similar to AN-M166, except for some minor details. It may be used with GP, Frag Chem bombs of 100-lb and higher (Ref 51a, p 4-90)...

Of course, all of the described types of detectors can locate ordnance. Many UXO technicians still mag and flag using a hand-held cesium vapor magnetometer. If all anomalies are to be intrusively investigated, these work fairly weU. But they will not find brass or aluminum fuses and detonators, lead projectiles, or aluminum-cased bombs. On range impact areas, any loose fuses are likely to have detonated anyway. However, on impact areas the amount of shell fragments (frag) render the cesium...
