Multi-Payload Projectile (MPP)

The Multi-Payload Projectile (MPP) is a drone-based loitering munition developed by the Norwegian-Finnish defense contractor Nammo. Introduced in 2023, the system is designed to be fired from standard 155 mm howitzer barrels, allowing existing artillery platforms to deliver autonomous sub-munitions. The projectile functions as a carrier that dispenses smaller, independent drones in flight, expanding the targeting options for field artillery units.

Nammo, headquartered in Raufoss, Norway, describes the MPP as a reconfigurable payload system. The core concept involves launching a single artillery shell that, upon reaching a designated area, releases multiple autonomous sub-munitions. These sub-munitions are capable of loitering and engaging targets independently, providing a flexible response to dynamic battlefield conditions. The system aims to bridge the gap between traditional indirect fire and precision-guided munitions by leveraging the range and availability of standard artillery ammunition.

As of the last research update in May 2026, the MPP has not been confirmed as combat-tested in active conflict zones. There are no publicly verified reports of the system being deployed by military operators in combat scenarios. Consequently, specific data regarding its operational effectiveness, hit rates, or performance against countermeasures remains unavailable. The lack of combat experience means that claims about its tactical utility are currently based on manufacturer specifications and theoretical models rather than empirical battlefield data.

The MPP represents Nammo’s expansion into the loitering munition market, a sector increasingly dominated by dedicated drone manufacturers. By integrating autonomous capabilities into a standard artillery format, Nammo seeks to offer a solution that does not require specialized launchers or infrastructure. This approach aligns with broader trends in modern warfare, where the ability to rapidly deploy precision effects from existing assets is highly valued. However, the distinction between the manufacturer’s promotional materials and verified operational capabilities remains significant.

While the MPP offers a novel method for delivering autonomous sub-munitions, its role in current military doctrines is still undefined. Without confirmed deployments or independent analysis of its performance, the system remains a conceptual offering within Nammo’s portfolio. The focus on artillery-launched drones highlights the ongoing evolution of indirect fire, but the practical impact of the MPP on the battlefield cannot yet be assessed.
