How do propellants differ from explosive fillers in ordnance?

• A. Propellants propel projectiles; explosive fillers provide energy for detonation or fragmentation
• B. Propellants detonate; explosive fillers propel projectiles
• C. Propellants provide energy for fragmentation; explosive fillers stabilize the round
• D. Propellants cool the ordnance; explosive fillers insulation

Answer: (A)

Propellants are the energy source that creates high-pressure gas to push the projectile out of the barrel; their effect is propulsion, not the warhead final energy. They burn to generate thrust as the round exits the muzzle. Explosive fillers, by contrast, are the main warhead charge inside the round and deliver the energy needed for detonation or fragmentation once the fuze triggers. So, the propellant’s role is to propel, while the explosive filler’s role is to produce the explosive effect (blast or fragments) at the target.
