Are Drones the Future of War? Lessons from Ukraine

Lawrence Freedman

The prominent role of Uncrewed Aerial Vehicles (UAVs), better known as drones, in the Russo-Ukraine War has led to suggestions that we are witnessing a transformational moment in the conduct of war, and can now look forward towards futuristic robotic conflicts fought between machines, loosely controlled by distant humans. Before we get quite that far we can expect to see drones performing an increasing range of military tasks, as a relatively inexpensive way of finding and hitting distant targets.

Drones have been around for almost as long as manned aircraft, but gained attention early in this century as the Americans began to use them as part of the ‘war on terror.’ By the time of President Obama’s first term there were used regularly for targeted assassinations, notably in Afghanistan and Pakistan, justified as a means of reducing threats without having to put troops in harm’s way. Eventually Obama worried about the ethical and legal implications of these attacks. Too often the intelligence was poor and innocents were killed because they suddenly moved into the line of fire without any reason to know they were in danger.

The easy availability of inexpensive commercial drones allowed them to be used by rebels and insurgents to fight stronger armies. During the Syrian civil war repurposed civilian drones began to appear as a simple means of dropping grenades on enemy units in close encounters in urban environments. When Hamas launched its attack on Israel on 7 October 2023, it used off-the-shelf drones to hit cameras and communication towers along the Gaza border to enable its men to advance undetected into Israel.

Once Israel, a pioneer in the development of drones, and with long experience of using them to operate in hostile areas, got the upper hand it used them to survey and increasingly attack Palestinian targets, as well as support ground operations. There have been reports of the use of ‘sniper’ drones, which carry lightweight firearms that can shoot at targets when triggered by remote operators. These have been blamed for many civilian casualties. Robotic versions of other vehicles, including bulldozers, have also been reported.
