Germany Kicks Off Work On Leopard 3 Main Battle Tank
Germany has moved a step closer to building a new main battle tank — already dubbed Leopard 3 — with a contract issued for technical studies of 130mm ammunition, as well as a powerplant, protection systems, and other equipment. The resulting systems are expected to find their way into an interim tank that will be operated by the German military pending the arrival of an all-new Franco-German main battle tank. This more advanced tank may well also end up using some of the same equipment now being studied.
The German Armed Forces procurement office, the BAAINBw, published details of the technical studies on TED, the European online procurement platform. The announcements were first reported in the media by the German defense and security website hartpunkt. These reveal that technical studies have been commissioned to cover three different areas: firepower, mobility, and protection.
So it seems Germany might be developing a Leopard 3 tank. Recent contracts announced by the BAAINBw point to the following developments: – Ammunition for the @RheinmetallAG 130 mm gun– New engine from @Liebherr – Improved protection from @hensoldt – And improvements to the… pic.twitter.com/a87dE9mtpz

All of these new technologies are intended to be compatible with the existing Leopard 2 main battle tank. However, should they eventually be integrated into a single platform, the result will be a significantly different tank. This will likely be designated Leopard 3 — although it has also been described as the Leopard 2 AX or 'the bridge solution.'
The study for 130mm ammunition will be conducted by Rheinmetall. This reflects a broader interest in moving to increased-caliber tank armament and the gun itself is something that Rheinmetall has been working on for some time now.
This work is broken down into three components, for three different ammunition types: the DM13 rounds that will be used as qualification ammunition for trials; DM11 multifunctional high-explosive ammunition; and DM23 kinetic-energy anti-armor ammunition.
It was previously known that a large-caliber 130mm main gun was being planned for the Main Ground Combat System (MGCS) a Franco-German project that seeks to field an advanced new main battle tank as well as a 'system of systems' of other crewed and uncrewed vehicles. The tank component is expected to ultimately replace Germany's existing Leopard 2s, as well as France's Leclercs.
Rheinmetall's 130mm gun has also been around for some time.
The smoothbore gun, with 52 caliber lengths, was first revealed in prototype form in 2016. At the time, Rheinmetall said that the new gun would offer a 50 percent increase in kinetic energy compared with the 120mm gun used on the Leopard 2.
While this is significant, in terms of penetration power, the larger gun is also notably heavier and bulkier than the 120mm weapon. When it was unveiled, Rheinmetall said the 130mm gun weighed more than 7,700 pounds, compared with around 6,600 pounds for the 120mm gun. At the same time, the larger projectiles fired — each of which weighs more than 66 pounds and is around 4.2 feet long — require an automatic loader within a turret of revised design.
Rheinmetall has already carried out firing demonstrations with the 130mm gun, as well as extensive simulations and studies.
Meanwhile, Liebherr will be responsible for the study for a new engine, known as OLYMP. Like the 130mm main gun, this will be tailored for the 'interim' Leopard 3, but it could potentially have other applications too.
In the past, Liebherr has developed and produced engines for the Marder 1 infantry fighting vehicle as well as its successor, the Lynx KF41.
The BAAINBw description specifies a complete engine block, comprising the combustion engine itself as well as steering, manual gearbox, cooling system, combustion air filtration, and exhaust system. Also required are engine mounts to attach the power pack to the chassis, side gears, and connections to the control system and fuel supply. The study calls for the use of as many existing components from the Leopard 2 as possible.
Hensoldt and KNDS Deutschland are the two companies commissioned to study the increased level of protection for the Leopard 3.
This calls for the development of a 'significantly more combat-capable variant of the MUSS,' a reference to Hensoldt's existing Multifunctional Self-Protection System. This may result in a further enhancement of the MUSS 2.0 the company presented last year, for use on the Puma infantry fighting vehicle and other platforms.
The current MUSS 2.0 is a lighter-weight and lower-profile system than the original MUSS. It essentially consists of four passive sensors located around the vehicle. Each of these sensors combined a missile and laser warning sensor, as well as a laser-based infrared jammer and an infrared countermeasures dispenser. The system is designed to defend against anti-tank guided missiles, but it can also detect tracer rounds, muzzle flashes, projectile fire, and low-power lasers. The MUSS 2.0 is able to detect different threats simultaneously, prioritize them, and then counter them, in semi- or fully autonomous modes. The threat database can also be regularly updated, to deal with new and emerging threats.
Finally, two further technical studies have been awarded to Hensoldt and to KNDS Germany, calling for work in a field adjustment system. This is required to compensate for the effects of barrel bend, a phenomenon that is caused by changes in temperature and which can affect the accuracy of the main gun. In the Leopard 2, a manual system is used for field adjustment, which is the responsibility of the gunner. The BAAINBw wants a new system to be fully automated so that regular manual adjustment is no longer necessary.
The interim main battle tank, if development continues, will provide the German Armed Forces with a tank that will serve at least until the introduction of an all-new fighting vehicle, being developed under the MGCS project.
The report from hartpunkt, which cites unnamed defense insiders, suggests that the interim Leopard 3 (provided it receives this designation) will be 'adapted to the current threat level in terms of performance and will have additional capabilities compared to the Leopard 2A8.' The latter is currently the most advanced production version of the Leopard 2. The report adds that the interim tank should start to enter service in the 2030s — if the German government gives it the go-ahead. The tank should then serve for around 25 years.
At this stage, the final specifications of the Leopard 3 are still to be determined, and they will likely be refined after these three technical studies are completed. The German Armed Forces procurement office expects this work to be finished by the end of 2026.
It's unclear where the new technical studies will leave the Leopard 2 A-RC 3.0 version of the Leopard 2, which was rolled out by Franco-German defense conglomerate KNDS last summer, as you can read about here.
This new version of the Leopard 2 features a completely uncrewed turret that can be armed with an even larger 140mm main gun. The tank also features a built-in anti-tank guided missile launcher and a remote weapon station armed with a 30mm cannon optimized for engaging drones, a threat that has now fully emerged thanks to the war in Ukraine.
KNDS wants to offer the Leopard 2 A-RC 3.0 for sale but also expects it to be a key stepping stone to the next-generation MGCS.
Last year, KNDS announced it would establish a new joint company with Germany's Rheinmetall and Thales in France specifically to work on MGCS.
As for Rheinmetall, this company also unveiled its own next-generation tank, the KF51 Panther, back in 2022. The KF51 also has a 130mm main gun — as specified for the new interim tank — in a more traditional crewed turret. That turret also features a built-in launcher for missiles or drones and the option to install a remote weapon station on top. You can read more about the Panther's design and capabilities here.
It had previously seemed likely that the Leopard 2 A-RC 3.0 would find itself in direct competition with the KF51 and, while that may be the case for sales outside Germany, the latest technical studies suggest that the BAAINBw is eyeing a different solution. While this will be broadly based on the Leopard 2, it will be a more ambitious project than the Leopard 2 A-RC 3.0, which does not — as far as is known — include a new powerplant.
Regardless, it's notable that Germany is once again very active in tank development, something that reflects wider trends.
After years during which many tank operators either reduced their fleets or removed them altogether, armored warfare is now experiencing something of a renaissance, spurred, in no small part, by the full-scale invasion of Ukraine.
While France and Germany remain committed to the MGCS, the German Armed Forces clearly see a requirement for a main battle tank that can be introduced to service before this next-generation fighting vehicle becomes available. In the meantime, these German studies for an interim main battle tank — whatever it might be called — look like they could also provide a pointer to what the future MGCS tank could look like.

China's grueling ‘996' work culture is being debated by European startups — 7 founders and VCs on why they are resisting
The European startup scene was recently shaken by a LinkedIn debate with some venture capitalists applying pressure on founders to embrace a culture of overwork to compete on a global stage. The "996" work culture reigns supreme in China and has been adopted by various tech giants including Jack Ma's Alibaba and Bytedance's TikTok, but the system has also been the subject of much protest in recent years. Tech workers in Europe told CNBC in 2021 that they're turning down job offers, rejecting interviews, or even quitting their roles, upon learning of TikTok's 996 work culture. Sebastian Becker, general partner at Switzerland-based VC company Redalpine added to the debate on LinkedIn by addressing the new German Chancellor Friedrich Merz, who has called for removal of the legal work limit of eight hours per day in Germany in a bid to increase efficiency, while keeping the 40-hour week. Becker said Merz' proposal doesn't go far enough, as "40 hours a week won't cut it." "In Silicon Valley, 60-70 hour weeks aren't the exception — they even have a term for it: 996 — 9am to 9pm, six days a week... we can have the same amount of smart, ambitious people, but if we're consistently being outworked, we won't win," Becker said. Index Ventures Partner Martin Mignot in London explained on LinkedIn that 996 originated in China and has "quietly become the norm" at startups internationally. Part of the reason behind this most recent push is that there's a persistent view that Europe's tech and startup scene is lagging behind the U.S. and China, both of which have produced tech giants and are known for intense work cultures. However, Suranga Chandratillake, general partner at Balderton Capital, told CNBC Make It that these views are outdated as Europe has produced deca-corns in recent years— companies worth more than $10 billion including Klarna, Revolut, Wise, and The continent has yet to produce a trillion-dollar tech firm like Nvidia. "The European tech market and ecosystem is keeping up today with the U.S. and Asia... back in the 1980s the European tech scene was behind the tech scene on the West Coast of the US, but that's not the case now," Chandratillake said in an interview. The calls for Europe to adopt the 996 work culture sparked a wave of backlash. CNBC spoke with seven European startup founders and VCs on why they disagree. The obsession with China's 996 or Silicon Valley's 24/7 work culture emerges from a glorification of hustle culture in the startup landscape, founders and VCs said. "It's about a fetishization of overwork rather than smart work…it's a myth," Chandratillake said. "California is very good at telling stories and there's a lot of mythmaking around the concept of what startups look like…. there is hard work involved but if you really spend time in that ecosystem, you will discover that lots of people work really hard, but there are also periods where they don't work." Nina Mohanty, a Silicon Valley native and founder of London-based Bloom Money, said there are actually "lasting effects and unintended consequences" to adopting an aggressive overwork culture, "You only have to think about Revolut and the culture that they have is probably the closest that we've seen in Europe to the 996 culture, and they struggled," Mohanty told CNBC. "Their churn rate was incredibly high within their team, and they even struggled to get their banking license, and their culture was actually cited as one of those reasons." For its part, Revolut told CNBC it operates in a "high-growth, high-performance environment." "In line with this, we've evolved how we support our people: through value-based behaviours, structured development, and a culture that's collaborative, challenging, and built for scale," a spokesperson from Revolut said. Noa Khamallah, general partner at Don't Quit Ventures, pointed out that there's "no need for 996" and that these values are often at odds with both the European mindset and regulation. "Europe's most successful companies — from Spotify to SAP to ASML — didn't achieve dominance through overwork but through sustainable innovation cultures," Khamallah said. He offered the examples of Silicon Valley's Uber and Meta, both companies that expanded into Europe and faced massive regulatory pushback. "These examples reveal how Silicon Valley's 'move fast and break things' ethos often breaks against European values around worker rights, privacy, and sustainable business practices," Khamallah said. An always-on culture decreases retention and creates a revolving door of talent, Sarah Wernér, co-founder of Husmus, told CNBC. "Overwork today is a productivity crisis tomorrow," Wernér said. "Personally, I hope my competitors are doing 996. It makes poaching great people a lot easier when they decide they've had enough." Dama Sathianathan, a senior partner at Bethnal Green Ventures said it's unhelpful to "prescribe" working hours, especially if it means putting workers' wellbeing at risk. "Optimizing labor doesn't always lead to better productivity, or help with differentiating from other companies long-term, if you've made work devoid of meaning," Sathianathan explained. Meanwhile, the youngest generation at work are less likely to put up with overworking and tend to prioritize work-life balance. Jas Schembri-Stothart, founder of Luna, a health and wellness app for teen girls, said 996 will drive young talent away from European startups. "People may tolerate overwork for a while, but eventually it leads to churn and even resentment, especially with Gen Z and younger millennials, there's much less tolerance for toxic hustle cultures," Schembri-Stothart said. Founders insist that instead of increasing working hours, startups need more funding and resources to position themselves as key players in the global startup scene. "What Europe really needs isn't more hustle-porn it's more aggressive funding," Wernér said. "With the right level of capital, our startups can hire enough talent to work intensely without breaking themselves. If a team of 10 is burning out to keep up with a 50-person U.S. VC or Chinese government-backed startup, the problem isn't their stamina, it's their cap table." In fact, since 2015 Europe's tech startups have missed out on nearly $375 billion in growth-stage funding, with founders losing out on a potential $300 billion in European investments, according to Atomico's State of European Tech report published in 2024. Additionally, one in two companies raising funding turn to the U.S. for capital rather than Europe. "What European startups really need is access to the right resources — funding, talent, and support — to grow, innovate quickly, and scale effectively," Schembri-Stothart said. "The venture landscape in the U.S. is a different ballgame altogether, and it's tough to compete with that without a stronger ecosystem here. Founders acknowledged that the startup life requires intense hustle and grind, but it's a more nuanced picture than just adopting 996. Timothy Armoo, co-founder and former CEO of Fanbytes, an influencer marketing firm that he sold for eight figures in 2022, told CNBC that he's a "huge supporter" of this new 996 push, but admitted that timing is key. "I think there are seasons but I also think that if you are a first-time founder or if your primary goal is basically wealth creation, I'll be very candid, if this is your season, and you're stepping back, then you're not serious about it," he said. Armoo said there are no excuses because AI allows entrepreneurs to be maximally efficient as it can reduce certain time-consuming manual tasks. Meanwhile, Bloom Money's Mohanty, said that when she's not sleeping, she's working. "I think early stage teams tend to almost unknowingly or without actually saying it, work the 996 life, because when you are early stage, you just have to hustle harder with less, and especially if you're the founder, you're always on and always working, and it can be very, very difficult to turn off." Schembri-Stothart draws the line at exploiting her team to produce more work. "It's my choice to work at the weekend, but I'd never expect that on my team, it's definitely not glorified to push your teams to breaking point. Silicon Valley tech exec Dion McKenzie warned that expectations of a 996 culture could make VC funding even more out of reach for early-stage startups. "My fear is that as these new norms and trends become the status quo and benchmarks for getting funded, it excludes so many brilliant founders that value their mental health and/or can't commit to a 996 due to caregiving responsibilities or being a parent," Mckenzie said.

Germany plans to revamp shelter system in case of Russian attack by 2029: ‘We are concerned about the risk of a major war'
Fearing Russia could attack another European country within the next four years, Germany is planning to expand its network of bomb-proof bunkers and shelters, according to reports. 'For a long time, there was a widespread belief in Germany that war was not a scenario for which we needed to prepare,' Ralph Tiesler, the head of the Federal Office of Civil Protection and Disaster Assistance, said in a recent interview as reported by The Guardian. 'That has changed,' Tiesler said. 'We are concerned about the risk of a major war of aggression in Europe.' Advertisement 4 Germany's civil protection agency chief is warning that the country is not prepared for a Russian attack. Fears are mounting that the Kremlin — following its three-year war in Ukraine — could be capable of attacking a NATO country by 2029, so Germany must 'muster a functioning, comprehensive defense system by then,' Tiesler said. And time is of the essence. Germany cannot rely on building new bunker facilities in time so Tiesler's agency is working on plans to transform tunnels, metro stations, underground garages, car parks and the basements of public buildings into shelters. Advertisement To be presented this summer, they would create shelter for 1 million people, he estimated. The country has about 2,000 bunkers left over from the Cold War but fewer than 600 are in working order and most will require pricey renovations, Tiesler explained. Plus, those would only shelter about 480,000, less than 1% of the German population. 4 Germany's Federal Office of Civil Protection and Disaster Assistance is working on plans to transform metro stations and tunnels into shelters. 4 Germany's existing bunkers are nearly 80 years old and in need of renovations. Advertisement Finland, on the other hand, has 50,000 bunkers that could hold 4.8 million people, or 85% of its population, according to Tiesler's office. The agency leader is urging German Chancellor Friedrich Merz to fund the plans, as well as efforts to revamp apps, road signs and siren systems that would be used if residents need to take shelter. 'We don't want to unnecessarily frighten anyone, but we must nevertheless clearly warn of the danger of a military attack,' Tiesler told news site Zeit Online. 4 Russia's brutal war in Ukraine has caused fears in other European countries. AP Advertisement Russia's invasion of Ukraine has sparked similar concerns across Europe, motivating some countries to begin defense preparations. Poland, which borders Russia and Ukraine, plans to spend almost 5% of GDP on defense this year, the more than any of its NATO partners, the BBC reported last month.

The cheapest grocery stores in 2025 have been named — and the first-place winner is expanding in NYC
Check out these checkouts. As food prices are expected to rise by up to 3.5% in 2025, according to the USDA, many Americans are looking for ways to keep their grocery bills in check. A recent study by MarketForce, which surveyed over 4,300 shoppers, highlights the grocery stores that best balance affordability with quality. Whether it's inflation, supply chain issues or simply the high cost of living, everyone could use a break at checkout. Here's your chance, according to the roundup, with seven grocers helping customers stretch their dollars without sacrificing taste or freshness. Lidl has been a rising star in the U.S. discount grocery scene, especially in NYC, where it has been expanding locations, including in Brooklyn. The store layout is inspired by European roots, which helps Lidl keep its overhead low by minimizing staffing and using a streamlined warehouse-style setup. This helps reduce costs for shoppers, making it one of the most budget-friendly options for families. According to the MarketForce study, an impressive 81.4% of customers return to Lidl because of its unbeatable value. The store's affordable pricing is made better with the quality of its products, the report notes. In addition to the usual grocery items, Lidl also surprises customers with seasonal and non-food items, from power tools to potted plants. If you've ever dreamed of paying Costco prices without the membership fee, WinCo Foods is where it's at. This employee-owned chain has become a household name in many parts of the U.S., with 139 locations spread across 10 states. WinCo operates a warehouse-style model focusing on low prices by cutting out the middleman. It buys directly from manufacturers and even has customers bag their own groceries. The strategy must be working: a whopping 73.1% of shoppers cited value for money as their main reason for frequenting WinCo. Its bulk sections are also noted as a treasure trove for those seeking to stock up on essentials like flour, rice and dried goods at steep discounts. Grocery Outlet's business model revolves around selling overstocked or discontinued items at discounted prices. Locations vary by region, but the appeal is universal: customers can score big on both name-brand and private-label products. Fresh produce, dairy and meat are always stocked, while their natural and organic sections offer a variety of specialty items like vegan and gluten-free foods — often for less than what you'd find at other places. Notably, 71.4% of shoppers reported returning to Grocery Outlet for the exceptional value it provides. Aldi's reputation for value is legendary — and the numbers don't lie. The MarketForce study found that 70.4% of shoppers favor Aldi for the exceptional value it offers. With a European-inspired model, Aldi keeps costs low by minimizing staff, using simple displays, and encouraging customers to bag their own groceries. Despite this no-frills approach, Aldi shoppers can find everything from pasta and canned goods to frozen items and fresh produce. If you're looking to make your budget stretch even further, Aldi is also home to great deals on dairy, baked goods and even alcohol. Known for its vast selection of high-quality store-brand products, Wegmans is a favorite among many shoppers, particularly in the Mid-Atlantic region. The family-owned grocer boasts more than 110 stores and has become well-known for its excellent customer service and affordable prices. A solid 68.7% of MarketForce respondents cited value for money as their main reason for choosing Wegmans. Wegmans stands out for its wide range of organic and healthy food options, from fresh produce to gluten-free snacks. The grocer expanded to Long Island earlier this year and continues to extend its reach beyond the Northeast. Despite its smaller footprint compared to traditional grocery stores, about 67.2% of study participants mentioned that they return because of the store's value. While it's famous for its affordable and fun frozen-food options, much-beloved Trader Joe's also serves up fresh produce, unique snacks, seasonal items and high-quality private-label goods. While Costco may require a membership, the savings it offers can make it worth the investment. Known for its bulk-buying model, Costco allows customers to purchase everything from household essentials to luxury items at steeply discounted prices. Whether it's buying a year's supply of toilet paper, a bulk pack of fresh fruit, gourmet cheeses or pantry staples, according to the MarketForce study, 61.4% of customers return to Costco for its impressive deals.
