Answer :

Final answer:

The FMU-139 (series) electric bomb fuze is linked to precise timing mechanisms in munitions, though specific arming times for these fuzes are not provided. They play a crucial role in the functioning of weaponry, ensuring the exact moment of detonation which is vital for a gun-type fission bomb's energy yield.

Explanation:

The FMU-139 (series) electric bomb fuze is significant to understanding the principles of munitions operation, particularly in relation to the timing mechanisms involved in detonating weaponry. While specific arming times for the FMU-139 (series) fuzes are not provided in the provided text, the context around gun-type fission bombs such as that for 235 U offers insight into the importance of timing in nuclear armaments. In the case of a gun-type fission bomb, explosive charges propel two subcritical masses of uranium inside a cannon barrel. The energy yield of the fission reaction is not just a factor of the quantity of uranium but is highly dependent on how long the uranium masses can be held together before the bomb disassembles itself. This principle also applies to the precision of timing mechanisms such as fuzes necessary for the operation of such devices.
