Russia has fielded a new generation of cheap, jet-powered drones and cruise missiles faster than Ukraine or the US can build defenses against them, according to The Wall Street Journal. The weapons run on Chinese parts that slip past Western sanctions, and they are already getting through air defenses designed to stop slower drones. Analysts say the West underestimated how fast Moscow could move from an idea to a full assembly line.

Russia now leans on cheap, mass-produced drones to swamp Ukraine's air defenses with sheer numbers night after night, and its factories keep growing to keep the attacks coming. The bigger lesson reaches past this war: in a long fight, cheap weapons in large numbers can beat a small stock of expensive ones.

A cheap weapon that gets past Ukraine's defenses

Ukraine had learned to shoot down the Iran-designed Shahed drones Russia was launching. Then Moscow moved the goalposts. The newest model, the Geran-5, looks more like a missile than a drone—Mike Monnik, head of the drone-threat firm DroneSec, called it "essentially a poor-man's cruise missile," and it forced a rewrite of Ukraine's counter-drone playbook. The Geran-5 and the Banderol cruise missiles are each estimated to cost about $100,000. A US Tomahawk costs more than $2 million.

Built fast, with China's help

Moscow needed only about two years to take each weapon from the drawing board to the battlefield, reworking earlier designs, testing them in combat, and pushing them into serial production. Ukrainian assessments, echoed by the drone-intelligence firm DroneSec, trace the leap to Chinese parts—the turbojet engines, the navigation computers, the radios—most of them off-the-shelf, dual-use gear anyone can buy. The weapons are aimed at Ukrainian cities and infrastructure—a Banderol struck a residential area of Kharkiv in July.

An expensive problem for the West

US forces and NATO have knocked down cheap drones with costly Patriot interceptors and fighter jets, often firing several interceptors at a single weapon. Western firms that built interceptors for slow drones are now scrambling to make faster, jet-powered ones. Kateryna Bondar of the Center for Strategic and International Studies said the West keeps underestimating how fast Russia turns experiments into production, and that Kyiv had years of warning yet was still caught off guard.

"I'm surprised everyone is surprised," she said.

At NATO's July summit in Ankara, members committed more than $40 billion to counter-drone defenses over the coming five years.

Russia has upgraded the Iranian Shahed it fires at Ukraine into jet-powered drones that Iran now wants back, the Financial Times reported. Tehran plans to use them in its own war against Israel and the United States, the paper reported, citing Western intelligence.

Russia now fights with weapons it churns out and revises mid-fight, a homegrown production model fast enough to turn a cheap imported airframe into something its original supplier now wants back.

From a 185 km/h propeller drone to a jet that looks like a missile

Russia started building the Geran, its own version of Iran's Shahed, in 2023. The first Geran-1 flew at up to 185 km/h with a 20-kilogram warhead. The newest Geran-5 flies at up to 600 km/h, carries a 90-kilogram warhead, and has a range of up to 1,000 km. Newer models add thermal cameras, AI-assisted guidance, Russian anti-jamming antennas, and Chinese mesh modems.

Serhii "Flash" Beskrestnov, a non-staff adviser to Ukraine's president on defense technology, has described how such drones work:

"A Russian operator flies at an altitude of 2–5 km, spots the target, locks onto it using the camera, and then the Shahed automatically attacks the target."

Almost all of Russia's jet drones used against Ukraine carry such a camera, he added.

Skipping the testing, straight to combat

Centralized production lets the Kremlin redesign fast and fold in combat lessons.

"The reason Russia was able to create a major new production line from scratch was because it's technologically a lot simpler than making something like tanks, which require enormous, unique and costly machine tools," said Ruslan Pukhov, who heads the Moscow-based Center for Analysis of Strategies and Technologies.

He added that they essentially skipped the long testing period that usually accompanies any military development process, with changes going straight into production and being checked in combat.
