What are Cope Cages? Is this the new battle tech? Ukraine war sees bizarre armor to outsmart deadly drones
are Ukraine's unconventional answer to one of modern warfare's deadliest threats — cheap, explosive-laden FPV drones. Born from battlefield necessity, these DIY anti-drone armors are welded onto tanks, Humvees, and Bradleys, turning them into makeshift fortresses. What began in 2022 as crude steel grids has evolved into engineered mesh shields and angled plates designed to deflect or detonate drones before impact.
On the front lines, soldiers and mechanics are rethinking protection in real time, proving that in today's war, innovation isn't always high-tech — sometimes it's a steel cage, built by hand, that decides whether a vehicle survives.

In 2024, Ukrainian military intelligence estimated that small explosive drones were responsible for disabling or destroying up to 40% of front-line armored vehicles. Russian forces reached similar conclusions, prompting both armies to adapt.
The economics are brutal. A $500 FPV drone carrying a shaped charge can turn a $10 million Abrams or a Soviet-era T-72 into a smoldering wreck in seconds. The cages, often made from scrap rebar, salvaged fencing, or purpose-built steel plates, are a last line of defense against this imbalance.

Cope Cages: Ukraine's strange-looking armor that's saving vehicles from drones
Cope Cages are Ukraine's improvised yet increasingly sophisticated armor systems designed to protect military vehicles from deadly FPV drone strikes. These steel frames, mesh coverings, and angled plates — welded onto tanks, Humvees, and Bradleys — act as a shield to block or detonate incoming drones before they hit critical parts. First seen in 2022 as crude 'cage' add-ons, they've since evolved into battlefield-tested defenses shaped by trial, error, and necessity.
From crude frames to battlefield craftsmanship
The early versions of cage armor in 2022 were laughably basic — little more than welded grids that offered minimal coverage. By late 2023, workshops in Kharkiv, Dnipro, and Zaporizhzhia had transformed them into highly customized systems.
Cages have been seen with angled deflectors to force drones off-course, layered mesh to detonate charges prematurely, and even rotating mounts designed to allow crews to fire through the grid.
Some Ukrainian units now coordinate directly with metallurgical plants like Metinvest to source 8 mm hardened steel plates. These aren't just slapped on tanks — they're engineered to balance weight, visibility, and mobility. The goal: protect against a direct top-down strike without crippling the vehicle's suspension or blocking hatches.
The Russian 'turtle tank' problem
Across the front line, Russia has taken the concept to extremes. Their so-called 'turtle tanks' — T-62s and T-72s encased in full steel boxes with barely a slit for visibility — can shrug off some drone attacks, but at a price.
The reduced visibility and added tonnage mean these tanks often crawl at walking speed and are easy targets for artillery or anti-tank missiles. Ukrainian soldiers joke that they're 'mobile bunkers without the mobility.'
Yet, even with these drawbacks, the turtle tank concept reflects a grim truth: neither side can afford to ignore drone threats anymore.
Effectiveness — and limits — of DIY armor
Cage armor works best against single-strike drones with unmodified warheads. Against larger munitions, tandem charges, or multiple simultaneous hits, protection drops sharply.
A Ukrainian Bradley commander admitted that while his cage armor had saved his vehicle twice from FPV drones, the third hit from a modified anti-tank grenade still penetrated.
There's also the human factor. Cages can obstruct turret rotation, block optics, and slow crew evacuation. Some soldiers privately admit they feel 'safer but slower' — a trade-off that could be deadly if ambushed.
The next phase: integration into official design
What started as a DIY fix is moving into formal military doctrine. Ukraine's Ministry of Defense has quietly commissioned design guidelines for anti-drone protection, while Western suppliers are exploring modular cage kits for Abrams, Leopard 2, and Bradley platforms.
If this war continues into 2026, I wouldn't be surprised to see NATO exercises featuring tanks pre-fitted with factory-standard anti-drone cages.
What this means for modern warfare
The spread of cage armor in Ukraine is more than a tactical adaptation — it's a glimpse into the future of mechanized warfare.
It signals that top-down aerial threats are now a permanent feature of the battlefield, one that even the most advanced militaries must account for. The next generation of armored vehicles will likely be designed with integrated anti-drone systems, combining passive cages, active electronic jammers, and automated counter-drones.
For now, though, the steel grids and welded spikes rolling across the Donbas are a reminder that in war, innovation is rarely pretty — but often necessary.
FAQs:
Q1. What is Ukraine's DIY cage armor and why is it used?
It's a steel framework added to vehicles to stop explosive drones from hitting them directly.
Q2. How effective is Ukraine's DIY cage armor?
It can stop or deflect some drone strikes but isn't foolproof against heavy or repeated hits.

Aviation giant unveils aircraft that soars a month without refuelling - US navy already testing it
Skydweller: The Solar-Powered Drone Set to Redefine Aviation- Above the Gulf Coast, a quiet revolution in aviation is unfolding. Skydweller, a massive solar-powered drone, has emerged as a technological marvel capable of staying aloft for unprecedented durations. Recently, it completed a continuous 74-hour flight without relying on a single drop of fuel—a milestone that would have seemed impossible even a decade ago. With a wingspan of 236 feet, surpassing that of a Boeing 747, Skydweller is not just an oversized drone; it represents a paradigm shift in how engineers envision sustained, zero-emission flight. This isn't merely an engineering feat. It signals a new era where aircraft can operate autonomously for weeks, potentially months, without landing, refueling, or human intervention. The implications stretch from environmental monitoring to defense, maritime operations, and beyond. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Write Better, Work Smarter With This Desktop App Grammarly Install Now Undo How does Skydweller generate endless energy? At the heart of Skydweller's extraordinary capability lies its solar array. Spread across nearly 3,000 square feet of wing surface, more than 17,000 solar cells capture sunlight and convert it into electrical energy. Under optimal conditions, the array generates approximately 100 kilowatts—enough to power the aircraft during daylight hours entirely from solar energy. But flying is not just a daytime activity. To maintain continuous operation, Skydweller relies on 1,400 pounds of high-capacity batteries that store energy harvested during the day. At night, these batteries kick in, enabling uninterrupted flight. This dual-mode system—solar by day, battery by night—is what allows the drone to remain aloft for multiple days. Live Events What makes this endurance remarkable is not just the raw numbers. The energy management systems onboard are sophisticated enough to balance power, optimize flight efficiency, and ensure that critical systems never lose functionality. This is essential for long-duration autonomous missions where human intervention is limited or impossible. Skydweller so light for its size Skydweller's enormous wingspan might suggest a heavy, unwieldy craft, yet its total weight is only about 2.5 metric tons. Achieving this required extensive use of carbon fiber materials and advanced composites. By reducing structural weight without compromising strength, engineers have created a drone that can glide efficiently, carry payloads, and endure the stresses of long-term flight. The lightweight design has profound implications. For one, it reduces energy consumption, making solar power feasible for a craft of this scale. Additionally, it allows for increased altitude capabilities, enabling Skydweller to fly above weather systems or congested airspace while maintaining stability. Unlike conventional aircraft, which require significant fuel reserves to sustain long flights, Skydweller leverages its light construction and renewable energy to operate almost indefinitely under the right conditions. What makes its flight control system unique? A drone capable of flying for days or weeks cannot rely on simple autopilot systems. Skydweller employs a quadruple-redundant flight control network, paired with an intelligent vehicle management system. This architecture constantly monitors aircraft performance, detects anomalies, and can execute autonomous corrective measures in real time. In practice, this means the drone can adjust for turbulence, changing weather, or system malfunctions without human input. The control system integrates predictive algorithms that optimize flight paths for energy efficiency, battery preservation, and mission objectives. In essence, Skydweller functions as a highly intelligent airborne platform capable of independent operation, a leap far beyond typical commercial drones. For long-duration missions, this autonomy is crucial. Even minor errors, left unchecked over days of flight, could compromise the entire operation. Skydweller's systems are designed to mitigate risk at every turn, making it a reliable tool for applications where human oversight is impractical. Where could Skydweller change the game: From Oceans to Orbit? The potential applications for a drone like Skydweller are vast. Its endurance and altitude capabilities make it ideal for operations that were previously costly, dangerous, or logistically complex. Maritime Surveillance: Skydweller can patrol large swaths of ocean continuously, providing monitoring for illegal fishing, piracy, or environmental hazards such as oil spills. Unlike manned patrol aircraft that require fuel stops and rest cycles, this drone can maintain a constant watch, offering real-time intelligence over areas previously unreachable for extended periods. Military and Reconnaissance: The military potential is significant. Long-endurance drones can perform intelligence, surveillance, and reconnaissance missions without risking pilots or deploying manned aircraft into hostile airspace. A single Skydweller could replace multiple conventional sorties, reducing operational costs while maintaining a continuous presence in strategic regions. Environmental Monitoring: Scientists and conservationists can leverage the drone's capabilities to track deforestation, monitor wildlife migration, or observe climate phenomena. The drone's high-altitude perspective allows for wide-area coverage, while onboard sensors can collect data at a granularity impossible from satellites alone. Continuous monitoring opens new possibilities for ecological research, disaster response, and climate science. Communications and Connectivity: In remote or disaster-affected regions, Skydweller could act as a temporary airborne communications hub. Its prolonged flight time could support internet coverage, emergency communications, or broadcast relays without reliance on ground infrastructure. What Makes Skydweller So Extraordinary? 1. Solar-Powered Endurance Skydweller is equipped with over 17,000 solar cells spread across approximately 2,900 square feet of wing surface. These cells can generate up to 100 kilowatts of power under optimal sunlight conditions. During the day, the aircraft operates using solar energy, while at night, it relies on 1,400 pounds of onboard batteries to continue its flight. 2. Lightweight Yet Robust Design Despite its massive wingspan, Skydweller weighs just 2.5 metric tons—significantly lighter than traditional aircraft. This lightweight design is achieved through the use of carbon fiber construction, allowing for greater fuel efficiency and reduced environmental impact. 3. Advanced Flight Control Systems To ensure stability and safety during extended flights, Skydweller employs a quadruple-redundant flight control system and an intelligent vehicle management system capable of real-time diagnostics and repairs. This advanced technology enables the drone to operate autonomously for extended periods, even in challenging conditions. What challenges does it still face? Despite its successes, Skydweller is not without limitations. Battery technology, while advanced, still constrains maximum night-time endurance. Severe weather conditions, while navigable, require careful planning and monitoring. And regulatory frameworks for long-duration autonomous flights are still evolving, especially in national airspaces with complex traffic patterns. Yet the team behind Skydweller is already pushing boundaries. Next-generation designs aim to expand payload capacity, integrate more efficient solar cells, and improve battery storage, potentially enabling flights lasting months instead of days. There is also the prospect of hybrid missions, where drones like Skydweller work in tandem with satellites or ground-based systems to provide continuous global coverage. In many ways, the drone represents a bridge between traditional aviation and the future of unmanned, sustainable flight. Its success could pave the way for a new category of aircraft that operates with minimal environmental impact while offering unprecedented operational capabilities. Why this matters for aviation and climate Skydweller's emergence signals a fundamental shift in how engineers approach aircraft design. Historically, flight endurance has been constrained by fuel capacity and human factors. With solar power, lightweight materials, and advanced autonomy, these constraints are dramatically reduced. The result is a craft that can operate continuously, sustainably, and reliably—qualities that are increasingly critical as climate concerns and operational efficiency drive innovation in aviation. Moreover, long-duration drones could reshape industries. Maritime security, border monitoring, disaster response, and environmental research all stand to benefit from platforms that can operate indefinitely. In some cases, these drones could reduce reliance on traditional manned flights, cutting emissions and operational costs while maintaining—or even enhancing—effectiveness. A Glimpse Into the Future of Flight Skydweller is more than an impressive piece of engineering. It embodies a vision of aviation that is sustainable, autonomous, and capable of previously unimaginable endurance. Its solar-powered design, lightweight construction, and intelligent flight control systems position it at the forefront of a rapidly evolving field. In the coming years, drones like Skydweller could redefine the rules of engagement in both civilian and military skies. They promise a future where continuous flight is not only possible but practical, sustainable, and transformative. For aviation enthusiasts, environmentalists, and defense planners alike, the era of month-long flights without landing is no longer science fiction—it's taking shape above us, quietly but powerfully, one solar-powered wing at a time.

Vehicle fitness certification on pause at Dharwad West RTO; owners forced to move to other centres
Hubballi: Dharwad West RTO is currently hobbled with a defunct vehicle fitness testing device. According to RTO officials, the machine is currently not accepting fees for issuing fitness certificates. The worst affected are owners of commercial vehicles. They are now being forced to visit Haveri, Gadag, and Dandeli RTO offices to obtain fitness certificates issued manually. The irony is certainly not lost on anyone as though the machine is out of order, RTO officials are allegedly still imposing a fine on vehicle owners who are yet to renew their vehicle fitness certificates. Babanna, a school bus driver who frequently visits Dharwad West RTO, told TOI: "Consultants and staffers (at the RTO) are saying that the govt itself has stopped allowing clearances to transport vehicles." Many have demanded that the system of issuing vehicle fitness certificates must be unified. "The govt installed inspection and certification (I and C) centres in six districts, but these are all defunct since March. According to rules, we must pay the fees online, but I and C centres are not generating receipts for the fees paid. Hence, it's difficult to get a test or an inspection report issued," some vehicle owners said. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like TV providers are furious: this gadget gives you access to all channels Techno Mag Learn More Undo Making matters weorse, manual fee payment has been stopped, they said.

Autorickshaws in Mangaluru to get QR codes soon
Mangaluru: The Karnataka Drivers Union has submitted a proposal to the Mangaluru City Traffic Police to develop QR codes for autorickshaws operating in Mangaluru. The purpose of creating a database and QR codes is to prevent the misuse of zones allotted to the autorickshaws in Mangaluru. While there are 7,637 autorickshaws in zone 1 of Mangaluru city, zone 2 of Mangaluru rural has 6,949 vehicles. As per the zone rules introduced in 2006, zone 2 autorickshaws are not allowed to enter the city. The union members are working on developing QR codes for all rural autorickshaws to prevent misuse of zone rules. Ganesh R Shaktinagar told TOI that the union noticed zone rule violations by autorickshaws, especially zone 2 vehicles operating in Mangaluru city. "We noticed many autorickshaws, which were given the zone 2 stickers to operate in rural areas of Mangaluru, using the duplicate stickers of zone 1 to operate in the urban areas. Further, there are autorickshaws that have no documents operating in Mangaluru city limits. These duplicate autorickshaws have been causing serious issues. Hence, to prevent the menace of duplicate autorickshaws, including the duplication of zone stickers, the union developed software with QR codes for vehicles," he said. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Launch your PM career IITD PM Apply Now Undo Ganesh said that a memorandum in this regard was also submitted to deputy commissioner Darshan HV, who is also the Road Transport Authority (RTA) chairman. "We explained in detail the problems that arise due to the duplicate autorickshaw menace in the city to the DC. A memorandum was submitted to Mangaluru City Traffic police a few days ago, and the issue will also be discussed at the RTA meeting to be chaired by the DC on Aug 18," he said. He pointed out that middlemen reportedly misused the zone 1 stickers issued by Mangaluru City Traffic police. "As per our proposal, once the QR codes pasted on autorickshaws are scanned, data from the police record about its zone and ownership, as well as other details, can be accessed," he said. The district RTA stopped issuing permits for autorickshaws in Mangaluru city after 1997-98. Later, only for the purpose of govt schemes, permits were issued in 2014. Meanwhile, electric autorickshaws are allowed to operate without permits, but the next RTA meeting will discuss a recent govt order that made permits mandatory for electric autorickshaws too.
