That is, in the configuration using the solidifying agent described above, since the bullet was accelerated by the gas having a large molecular weight, there was an upper limit of the velocity of about 2 Km / sec.

Further, in the above-mentioned electrothermal chemical cannonball, since the water and the reaction object are independently provided by the partition wall and the whole is fixed by the container, the amount and the number thereof can be arbitrarily changed according to the target range. It was impossible to adjust the amount of propellant.

The present invention has been made to solve the above problems, and in particular, each independently formed propellant portion is an electrothermal chemical propellant consisting of water and a reaction substance such as aluminum or boron. An object is to provide an ammunition for an electrothermal chemical howitzer which is configured so as to increase the range by increasing the initial velocity and improve the shooting speed along with the ease of work.
