The distinction between a one-way attack (OWA) drone and a "true" loitering munition lies primarily in their operational behavior and tactical purpose.

While the terms are often used interchangeably, a loitering munition is specifically designed to remain in the air over a designated area for an extended period, actively searching for, identifying, and tracking targets before executing a strike. This capability allows for dynamic targeting and flexible engagement strategies.1

In contrast, many systems labeled as one-way attack drones—such as the Shahed-136—function more like slow, inexpensive cruise missile substitutes. These platforms are typically designed to fly toward a pre-programmed coordinate rather than to loiter and hunt for targets in real time.1

It is important to note that the term "one-way attack drone" is somewhat vague and often blurs the line between traditional uncrewed aerial vehicles and missiles. Furthermore, the common use of the term "kamikaze" to describe these systems is historically imprecise, as it originally referred to piloted suicide attacks during the Second World War.1
