"In the battle for Ukraine, the front line is increasingly at a standstill" because of "rapid innovations in drone technology..." according to the Wall Street Journal. "Each side has hundreds of them constantly in the air across the 750-mile front line."
And drones "now bring everything from food and water to ammunition, power banks — and, in at least one case, a fire extinguisher — to the front, sparing soldiers trips through the most dangerous part of the battlefield where enemy drones might pick them off."
Drones can lay mines, deliver everything from ammunition to medication and even evacuate wounded or dead soldiers. Crucially, drones spot any movement along the front line and are dispatched to strike enemy troops and vehicles. When Russia sent tank columns into Ukraine in February 2022, Ukraine needed to find out where they were headed — and fast. Enter the humble "wedding drone," available in stores for about $2,000 and repurposed to scan for enemy units rather than capture nuptial panoramas. Deployed by enthusiasts acting independently or attached to army units, the drones helped Ukrainian forces, which were vastly outnumbered and outgunned, to know exactly where to deploy to counter Russian arrowheads.
Surveillance drones quickly became a necessity rather than a luxury. Often provided by charity funds, they were used to scan enemy positions for equipment, stores and headquarters.... A cheap and simple tweak made the so-called wedding drones deadly. Tech buffs realized that a simple claw-like contraption, created using a 3-D printer, could be activated from the radio controller by turning on the drone's light, causing it to release a grenade. The explosion could wound or kill a soldier or even detonate an armored vehicle if dropped through its hatch. Over time, soldiers experimented with ways to add more explosives, for example by melting down explosives garnered from Soviet-era munitions and pouring them into new, lighter plastic casings.
No innovation has had a bigger impact on the war in Ukraine than first-person-view, or FPV, drones. With explosives strapped to them, FPVs fly directly into their targets, turning them into low-cost suicide bombers. Though FPVs don't deliver as much explosive punch as rockets, they are far more accurate — and the sheer volume that Ukraine has manufactured means they can be deployed to similar effect... Sitting in a bunker several miles behind the front, a drone pilot slips on FPV goggles to see the view from the drone's camera and fly it into an enemy position or asset. The Russians have since adopted FPVs en masse. Their abundance has played a central role in slowing down the movement of the front line. Anything within around 12 miles of the contact line can now become a target for FPVs. They are so cheap to make that both sides can expend them on any target — even a single infantryman.
Because they are so small and fast, FPVs are difficult to shoot down. The main defense against them has been electronic jamming systems, which disrupt the communication between the drone and the pilot. Though most drone innovations in the war have come from the Ukrainian side, the Russians pioneered the most important adaptation for FPV drones — the addition of a fiber-optic cable connecting the drone to the pilot that can overcome jamming.
Benjamin Franklin once predicted flying machines might "convince sovereigns of the folly of war... since it will be impracticable for the most potent of them to guard his dominions..."
