Which statement about explosive trains is correct?

• A. There is only one type of explosive train.
• B. There are four types of explosive trains.
• C. Explosive trains are not used with artillery ammunition.
• D. Projectile Explosive train and Propelling charge explosive train.

Answer: (D)

Explosive trains are the sequence of initiation devices that ensure reliable initiation of the main energetic charge. In artillery ammunition, there are two distinct explosive train systems. The Projectile Explosive Train operates inside the projectile and is responsible for detonating the bursting charge after the round is armed. The Propelling Charge Explosive Train handles the ignition of the propellant in the cartridge that propels the shell from the gun. So, the statement that there are two types—Projectile Explosive Train and Propelling Charge Explosive Train—is correct. The other options misstate the number, or claim explosive trains aren’t used in artillery, which isn’t true.
