Nemesis 155mm howitzer revealed as NATO’s next artillery leap.
On May 12, 2025, General Dynamics European Land Systems [GDELS], in collaboration with KNDS Deutschland, unveiled the Nemesis self-propelled howitzer at the International Defence and Security Exhibition [FEINDEF] in Madrid, Spain.
This new 155 mm/L52 artillery system, integrating a fully automated Artillery Gun Module [AGM] with the proven ASCOD tracked chassis, marks a significant step in modernizing artillery for contemporary battlefields.
Designed to meet the demands of rapid deployment, precision, and survivability, Nemesis aims to address evolving threats like drones and electronic warfare while offering a lighter, more agile alternative to traditional heavy artillery.
The unveiling, held at GDELS’ booth and streamed live on their website, underscores Europe’s push to bolster its defense capabilities amid rising geopolitical tensions.
The Nemesis system emerges at a time when artillery is undergoing a renaissance on the battlefield. Conflicts like the ongoing war in Ukraine have highlighted the critical role of mobile, high-precision artillery in countering advanced threats.
Traditional static artillery positions have become vulnerable to drones and counter-battery fire, prompting militaries to seek systems that can shoot and scoot—firing rapidly and relocating to avoid detection.
Nemesis, with its automated systems and reduced crew requirements, positions itself as a response to these challenges. Its debut at FEINDEF, Spain’s premier defense exhibition running through May 14, drew attention from military officials, industry experts, and international delegations, signaling strong interest in its potential applications.
At the heart of Nemesis is the ASCOD [Austrian-Spanish Cooperative Development] platform, a modular tracked chassis already in service with nations like Spain [Pizarro] and Austria [Ulan]. Developed by GDELS, the ASCOD is known for its balance of mobility, protection, and adaptability.
The version used in Nemesis, based on the ASCOD 2, weighs approximately 40 tons, making it lighter than many competitors like the German PzH 2000, which tips the scales at over 55 tons. This reduced weight enhances strategic mobility, allowing Nemesis to be transported by air or rail more easily, a key consideration for rapid deployment in crisis zones.
The chassis features a high power-to-weight ratio, driven by a diesel engine producing around 800 horsepower, enabling speeds up to 43 miles per hour on roads and robust cross-country performance. Its armor provides STANAG-certified protection against small arms, shrapnel, and improvised explosive devices, with options for additional reactive or active protection systems to counter anti-tank threats.
The star of the Nemesis system is its 155 mm/L52 Artillery Gun Module, a fully automated turret adapted from the PzH 2000’s proven design by KNDS Deutschland. Capable of firing standard NATO rounds to a range of 25 miles or extended-range munitions up to 34 miles, the AGM offers formidable firepower.
Its automation allows a crew of just two to operate the system, a significant reduction from the four or five required by older platforms like the U.S. M109 Paladin. The module includes an automated loader that handles both projectiles and modular propelling charges, enabling a sustained firing rate of six to eight rounds per minute.
This capability supports advanced tactics like Multiple Rounds of Simultaneous Impact [MRSI], where several shells hit a target simultaneously, maximizing the destructive effect before the system relocates.
The turret, equipped with a 360-degree traverse, can fire on the move, enhancing survivability against counter-battery threats. A remote weapon station, typically mounting a 12.7 mm machine gun, provides close-in defense against infantry or drones.
Nemesis integrates advanced sensors and fire control systems to ensure precision and situational awareness. While specific details on its electronics suite were not fully disclosed at FEINDEF, GDELS highlighted the system’s compatibility with network-centric warfare.
This suggests integration with digital battlefield management systems, allowing Nemesis to receive real-time targeting data from drones, forward observers, or satellites. Such connectivity is vital in modern conflicts, where rapid response to fleeting targets can determine outcomes.
The system’s fire control likely includes laser rangefinders, ballistic computers, and meteorological sensors to adjust for environmental factors, ensuring accuracy even at extended ranges. Posts on X from defense enthusiasts noted the system’s potential to leverage KNDS’s experience with the AGM, previously integrated on wheeled platforms like the Piranha IV for Switzerland, suggesting a mature technological foundation.
The historical context of artillery development provides insight into Nemesis’s significance. Self-propelled howitzers emerged during World War II, with systems like the U.S. M7 Priest offering mobility over towed guns.
The Cold War saw advancements like the Soviet 2S1 Gvozdika and the M109, which prioritized firepower and armor. However, the 21st century has shifted priorities toward automation and survivability, driven by lessons from conflicts in Iraq, Afghanistan, and Ukraine.
The U.S. Army, for instance, is exploring replacements for its aging M109 under the Extended Range Cannon Artillery [ERCA] program, with a competition planned for 2030, as reported by Breaking Defense. Nemesis’s European counterparts, like the French CAESAR and South Korean K9 Thunder, have set benchmarks for mobility and export success.
The K9, adopted by nations like Poland and Australia, combines a 155 mm/L52 gun with a 48-ton chassis, offering a firing range similar to Nemesis but requiring a larger crew. China’s PLZ-05, with its 155 mm/L52 gun, matches Nemesis in automation but lags in NATO interoperability, limiting its appeal to Western-aligned nations.
The operational implications of Nemesis are profound, particularly in high-intensity conflicts. In Ukraine, artillery accounts for a significant portion of casualties, with systems like the Russian 2S19 Msta-S facing heavy losses due to static positioning.
Nemesis’s shoot-and-scoot capability, enabled by its automated loader and mobile chassis, reduces exposure to counter-battery radar and drones. Its two-person crew minimizes logistical demands, allowing sustained operations with fewer personnel. The system’s network integration could enable it to coordinate with unmanned aerial vehicles for targeting, a tactic increasingly common in modern warfare.
For example, Ukrainian forces have paired M777 howitzers with commercial drones to devastating effect, a model Nemesis could enhance with its built-in connectivity. However, reliance on complex electronics raises concerns about vulnerability to electronic warfare, a growing threat as seen in Russian jamming operations against GPS-guided munitions.
Potential customers for Nemesis include NATO members seeking to modernize their artillery fleets. Spain, as the host of FEINDEF and a user of ASCOD-based vehicles, is a prime candidate, especially given GDELS’s local subsidiary, Santa Bárbara Sistemas.
Poland, which has invested heavily in artillery with over 600 K9 howitzers on order, may consider Nemesis to complement its forces, particularly for its lighter weight and automation. Germany, a partner in the KNDS collaboration, could integrate Nemesis into its future force structure, though its commitment to the PzH 2000 may limit immediate adoption.
Beyond Europe, nations in the Middle East, such as Saudi Arabia, or Asia-Pacific allies like Australia, which already operate NATO-compatible systems, might express interest. The global artillery market is competitive, with systems like the K9 and CAESAR dominating exports due to their proven track records and lower costs. Nemesis’s higher price, driven by its automation and advanced electronics, could pose a challenge, particularly for budget-constrained militaries.
The unveiling of Nemesis reflects broader trends in the defense industry. Europe is increasingly prioritizing indigenous solutions to reduce reliance on U.S. technology, a shift accelerated by geopolitical uncertainties and the need for rapid response capabilities.
The GDELS-KNDS partnership exemplifies this, combining German artillery expertise with Spanish manufacturing capacity. As reported by Defence Blog, the Nemesis system builds on the AGM’s prior integration with wheeled platforms, demonstrating modularity that could appeal to diverse customers.
However, the European defense sector faces challenges, including fragmented procurement and varying national priorities. The Swiss Army’s recent selection of the AGM on a Piranha IV platform for its M109 replacement program, as noted by Shephard Media, suggests growing confidence in KNDS’s technology, which could bode well for Nemesis.
Historically, GDELS has leveraged FEINDEF to showcase ASCOD variants, such as the CASTOR engineer vehicle in 2023, reinforcing the platform’s versatility. The ASCOD’s track record, with over 1,000 units in service across multiple nations, provides a reliable foundation for Nemesis.
Its lighter weight compared to the PzH 2000 or the Russian 2S35 Koalitsiya-SV positions it as a middle ground between wheeled systems like CAESAR and heavier tracked platforms.
The CAESAR mounted on a 6×6 truck chassis, offers superior road mobility but less armor, while the Koalitsiya-SV’s 152 mm gun and 55-ton chassis prioritize firepower over deployability. Nemesis’s balance of automation, protection, and mobility could appeal to armies facing diverse threats, from hybrid warfare to conventional conflicts.
The debut of Nemesis also highlights the evolving role of automation in artillery. Systems like the Swedish Archer, with its automated loading and minimal crew, have set a precedent, but Nemesis pushes further by integrating these features into a tracked platform.
This aligns with NATO’s emphasis on reducing logistical footprints, as seen in the U.S. Army’s exploration of autonomous systems. However, automation introduces risks, including cybersecurity vulnerabilities and maintenance challenges in austere environments.
The war in Ukraine has exposed the limitations of high-tech systems when supply chains are disrupted, a lesson GDELS and KNDS must address to ensure Nemesis’s reliability.
Looking ahead, Nemesis’s success will depend on rigorous testing and real-world performance. GDELS’s announcement at FEINDEF, as covered by Defence Industry Europe, emphasized the system’s alignment with modern military mobility requirements, but field trials will be critical to validate these claims.
The global artillery market is projected to grow as nations prioritize long-range precision fires, driven by lessons from recent conflicts. Nemesis’s ability to secure contracts will hinge on its cost-effectiveness and interoperability with NATO systems, particularly against established competitors like the K9 and CAESAR. For now, its unveiling marks a bold statement of Europe’s ambition to lead in artillery innovation.
From my perspective, Nemesis represents a calculated bet on the future of artillery, blending proven technology with cutting-edge automation. Its strengths—mobility, precision, and reduced crew requirements—position it well for modern battlefields, but its complexity and cost raise questions about widespread adoption.
The system’s reliance on networked systems, while forward-thinking, must be tempered with robust countermeasures against electronic warfare. As militaries grapple with the balance between capability and affordability, Nemesis could either redefine artillery tactics or remain a niche solution for well-funded armies.
