Since the first loitering drones appeared over Ukrainian cities in 2022, Kyiv’s defenders have learned to shoot
them down with everything from 1950s anti-aircraft guns to cutting-edge air-defence systems. Now a
jet-powered variant of Iran’s Shahed family—reportedly designated Shahed-238—has entered the
battlefield, demanding an even faster, cheaper, and more networked response. Below is a deeper look at
what makes the new threat different, how Ukraine is adapting, and why the outcome of this cat-and-mouse contest
could reshape drone warfare worldwide.
The Evolution of the Shahed Threat
• Shahed-131/136 (propeller-driven): Cruise at ~180 km/h, noisy, relatively easy to detect
with acoustic sensors and shoot down with guns or MANPADS.
• Shahed-238 (jet-powered): Estimated cruise of 400–600 km/h, smaller acoustic signature,
reduced engagement window, and the ability to fly higher profiles that place them beyond small-arms reach.
The new model still uses commercial navigation components and an explosive warhead similar to its predecessors,
but replaces the pusher propeller with a compact turbojet. That single change halves the defender’s reaction
time and complicates every step—detection, tracking, and interception.
Why Jet Propulsion Changes the Game
Speed vs. cost asymmetry. A Shahed-238 is estimated to cost Russia USD $200k or less,
yet forcing Ukraine to launch a NASAMS or Patriot interceptor priced in the millions erodes Kyiv’s finite
defence budget. The imperative is clear: develop a countermeasure that is both fast enough to
catch the drone and cheap enough to launch in volume.
Reduced radar cross-section. Higher speeds allow smaller airframes; smaller airframes return
weaker radar echoes. Existing radar nets calibrated for slower Shaheds must now be retuned or augmented with
additional sensors—especially low-power, wide-field AESA radars or passive RF detectors able to spot a turbojet’s
distinct emissions.
Flight-path unpredictability. Early Shaheds relied on pre-programmed GPS waypoints, but
Russian operators now blend inertial navigation with real-time course updates via satellite link, allowing last-second
dives or zig-zag approaches that challenge gun batteries and pre-laid missile ambushes.
Ukraine’s Current Counter-Drone Toolbox
1. Ground-based air defence (GBAD). Gepard SPAAGs, ZU-23-2 cannons, and IRIS-T or NASAMS
surface-to-air missiles remain the backbone but are poorly cost-matched for expendable drones.
2. Electronic warfare. Jamming stations such as “Nota” and “Bukovel” disrupt GPS guidance, but
inertial backups on Shahed-238 limit effectiveness.
3. “Barrel-eyed” spotters and searchlights. Human observers with night-vision still account for
a surprising share of successful detections.
4. Ad-hoc interceptor drones. Modified racing quadcopters laden with fragmentation charges have
downed slow Shaheds, yet cannot close on a turbojet target.
The Push for Purpose-Built Interceptor Drones
Ukrainian engineers—both state-run and volunteer—are now prototyping fixed-wing interceptor drones
capable of 500–600 km/h, guided by a combination of optical seekers, passive RF homing, and
command-and-control links into the national air-defence picture. Key programmes include:
• “Vyshchas” concept: A delta-wing airframe with a solid-fuel booster for rapid climb, then a
small turbojet for chase.
• “Kombat” loiter-interceptor: Uses an AI-assisted camera to identify the silhouette of a
Shahed, then executes a ramming strike, turning the entire drone into a kinetic kill vehicle.
• Revived Soviet target drones: Ukraine’s defence sector is overhauling cold-war era
VR-3/Reys target drones, swapping older engines for modern ones and adding self-navigation to create an affordable
SAM alternative.
Integration with Existing Air-Defence Networks
Interceptor drones only make sense if they launch before the Shahed enters its terminal phase.
Ukraine’s “Delta” battlefield management software is therefore being adapted to automate launch commands based on
real-time radar tracks. The goal: cut human decision time to single-digit seconds, matching the speed
advantage of jet-propelled drones.
Engineering Hurdles Still to Solve
• Propulsion vs. endurance. Turbojets guzzle fuel; designers must balance speed with at least
15–20 minutes of loiter time to chase multiple targets.
• Affordable seekers. A heat-seeking missile costs more than the drone it kills. Developers are
experimenting with cheap IR sensors salvaged from commercial thermal cameras combined with AI classification to
minimise cost.
• Networking under jamming. Russia routinely targets Ukraine’s Starlink and radio nets. A
resilient mesh-network among interceptor drones—similar to a swarm—could allow them to share targeting data even
if ground control is jammed.
International Support and Export Possibilities
NATO members have quietly supplied components—actuators, fuel pumps, data-link modules—under
dual-use export licences. Should Ukraine’s concept prove effective, a low-cost,
drone-on-drone air-defence package could become a hot export item for countries facing similar
“poor-man’s cruise missile” threats from Iran, North Korea, or non-state actors.
Outlook: A New Layer in the Air War
The appearance of jet-powered Shaheds marks the third major shift in Russia’s drone campaign: propeller-driven
loiterers, then hybrid cruise missiles like Kh-55, and now fast kamikaze UAVs. Each shift forces Ukraine to
innovate. If Kyiv can field interceptor drones that are cheaper than the Shaheds they destroy, the cost
calculus flips back in its favour—possibly neutralising an entire class of threat without draining high-end
missile stocks.
In the long run, the duel between jet-powered attack drones and autonomous interceptors is likely to spread beyond
Ukraine. As one Ukrainian engineer quipped, “We are the
beta-test site for the future of air defence.” The rest of the world is already taking notes.
