What type of warhead does the RPG-7 Unitary HEAT round use?

The RPG-7 Unitary HEAT (High-Explosive Anti-Tank) round utilizes a single-stage warhead design. This means that the round is engineered to unleash a focused jet of molten metal upon detonation, relying on a single energetic reaction to penetrate armor. The single-stage configuration allows for a simpler design, which contributes to its effectiveness against armored targets by creating a shaped charge.

In contrast, a multi-stage warhead would typically engage in multiple explosive stages to achieve enhanced effects, which is not the case for the RPG-7 Unitary HEAT round. A dual-stage design, while it may also involve more complex mechanisms for improved functionality, is not applicable here as the RPG-7 is designed with optimal efficiency and straightforward deployment in mind. Lastly, while the term "explosive" can broadly refer to many types of warheads, it does not specifically encompass the unique characteristics that define the performance and combat role of the RPG-7 Unitary HEAT round in modern warfare.
