Fire Bomb

These bombs (not described in Ref 44) consist of thin-walled containers filled with thickened petroleum products fuels 

750-/6 Fire Bomb, M116A2, shown here on Fig 2-12, is made of sheet A1 in three sections, (8), (11) (14), joined by a seal ring (23), to which is attached synthetic rubber gaskets (22). The center section is ca 18.63 inches in diameter and 48.63-in long, open at both ends. It is braced internally by A1 girders and reinforced on the side by an A1 plate. Two suspension lugs 

Upon release of the bomb from the aircraft, the arming wires are simultaneously withdrawn from the nose-cap plunger (5)

150-lb Fire Bomb Mkl8Mod2k consists of two sheet-steel half-shells welded together to form a body of different shape (See Fig 2-13) than shown of Fig 2-12.

Upon the advent of high performance jet-powered aircraft, the fire bomb became obsolete. When deUvered at speeds approaching Mach one (345 m/s), the design characteristics were often grossly exceeded and many units broke up or functioned while stiU on the aircraft. DeHvery from high altitude created craters and deposited most of the flame agent payload in those craters.

M2 Thickener A standard (for Air Force only) incendiary oil thickener. It is an intimate mixt of Ml thickener 95 devolatilized silica aerogel 5%- M2 thickener is an improvement over Ml, not only because of free-flowing faster setting characteristics, but also because the thickener itself ge 1 formed are more stable. It is used in fire bombs [Ref TM 3-215/AFM 355-7 (Dec 1963), p 4l]... 

In designation of Air Force items a more complicated system, which is hard to explain, is used. For example, BLU-10/B signifies a complete round for the 250 fire bomb... 

Unlike earlier types of fire bombs, the BLU-l/B utilizes electrically-armed impact fuzes which require a cable assembly to... 

Fuze M157 can also be used in 750-lb and 500-lb fire bombs, which are described below (See Figs 2-12, 2-13 and 2-14)... 

Bomb Nose (or Tail) Fuzes FMU 7/B or FMC/-7A/B are designed for use on later models of fire bombs. Two identical fuzes are employed in the nose and tail of each bomb. Electrically armed and impact fired, they are used in conjunction with FMU-7 initiators and cable assemblies...

Bomb Igniter, Ml5 is designed to be attached to a jettison-type aircraft fuel tank to adapt it for use as a fire bomb. 

When a fire bomb assembled with this igniter is dropped, the arming wire is pulled and the fuze arms after about 100-ft of air travel. On impact the fuze ignites and explodes burster chge and the rest is the same as described under igniter M15 (Ref 51a, p 5-24)... 

Two types, FMU-7/B and FMU-7AB, similar in construction and function, are described in Ref 51a, p 5-50 and are shown here in Fig 5 25. They are used in conjunction with FMU-7 series fuzes and cable assemblies in the BLU series fire bombs... 

Cable Assemblies FMU-7B and FMU-7A/B are electrical cables 0.19-inches in diam and 76-in long used to interconnect the FMU-7 series fuzes with the FMU-7 series initiators on BLU series fire bombs (Ref 51a, p 5-51)... 

Romans used the so-called firepot," which was a kind of iron fire bomb (as large as 2 ft in diameter) filled with pitch, sulfur, bitumen, etc and either perforated or latticed so as to permit emission of flames from burning charges. One such bomb may be seen on exhibition in the Tower of London...
