Innovative Use of Drones for Explosive Deployment and Countermeasures

The historical journey of grenades, which are explosive devices designed to detonate after being thrown by hand, can be traced back around 1,000 years to the Middle Ages. This period witnessed the advent of grenades bearing resemblance to modern-day equivalents.

Ancient civilizations had their own versions of grenade-like weapons. The “Greek Fire” bomb from the Peloponnesian War serves as an early example, dispersed by hurling a flaming jar or barrel using hand or catapult.

In medieval Europe, the specialized role of “grenadiers” evolved from the use of robust pottery or iron ball grenades, as these physically imposing soldiers braved the frontline to launch their explosive payloads.

However, with the advent of rifles and machine guns in the late 19th and early 20th centuries, the direct throwing of grenades by grenadiers fell out of practice. World War I saw a resurgence of grenade use due to the tactical implications of trench warfare.

The Evolution of Grenade Technology from Ancient Times to the Modern Battlefield

Noting the Japanese army’s effective grenade utility, the British Army developed the precursor to contemporary grenades – the “percussion” grenade or Hales bomb in 1908, marking a shift in warfare strategy.

Despite their potential, early grenades were plagued by production defects, which sometimes led to tragic accidents and their eventual decline in favor of improvised variants like the “jam tin grenade” and the “stick hand grenade,” which saw use until World War II.

Today’s battlefield has moved on to grenades with ‘delayed fuses’, making them safer and more reliable for soldiers.

New technology is now piloting the use of drones to overcome the limitations of hand-thrown grenades. Considering AI’s influence, the military is testing drones like the Drone40 to extend the reach and application of grenades significantly.

This innovation might lead to the concept of ‘air minefields’, where instead of direct bombardment, the drones carrying grenades hover over strategic areas, deterring enemy advancements.

Non-lethal alternatives such as surveillance and electronic warfare tools are also being considered for drone deployment.

Shin Jong Woo of the Korea Defense and Security Forum acknowledges the strategic enhancement provided by drone-deployed grenades but stresses the necessity for targeting precision due to high operational costs.

As drone applications expand, the Korea Drone Innovation Association plans to introduce grenade-carrying drones with advanced surveillance capabilities into military strategy.

Developing Drone Capture Technology with Net-Ejecting Grenades

In the wake of security incidents like the 2019 Gatwick Airport drone disruption, U.S. Army engineers at Picatinny Arsenal have conceptualized a grenade designed to apprehend rogue drones by releasing a net.

This innovative counter-drone measure, which functions by remote control or proximity sensor, shows promise in effectiveness and provides an efficient solution for handling a swarm of drones.
