What is the explosive train used to launch a projectile?

The explosive train used to launch a projectile is properly identified as the low explosive train. In the context of ordnance, a low explosive is typically utilized for propelling a projectile from a weapon. This type of explosive burns rapidly and produces a high volume of gas, which exerts pressure on the projectile to launch it from the barrel.

Low explosives are characterized by their ability to deflagrate rather than detonate, meaning they burn at a subsonic speed rather than creating a shock wave. This property makes them ideal for applications like propellants in firearms and artillery, where controlled, steady pressure is required to achieve the necessary launch velocity and trajectory without damaging the projectile or the weapon system.

In contrast, the high explosive train is generally used for demolition and destructive effects, creating powerful shock waves that can cause significant damage but are not suitable for the controlled launching of projectiles. Similarly, shaped charges and detonator trains serve very different purposes. Shaped charges are designed to focus explosive force to penetrate armor or materials, while detonator trains are primarily used to initiate a detonation in a chain reaction, not for propulsion.

Understanding the specific characteristics and uses of different explosive types is crucial for ensuring safety and effectiveness in military applications.
