Leonardo Vulcano 120 mm Ammunition: Enhanced Guided Indirect Fire Capabilities for Main Battle Tanks

Enhancing Tank Capabilities: The Vulcano 120 mm Guided Ammunition

The evolution of armored combat necessitates innovative solutions to counter contemporary threats on the battlefield. A pivotal advancement comes from Leonardo with the introduction of the Vulcano 120 mm guided ammunition, engineered to optimize the effectiveness of main battle tanks (MBTs) equipped with smoothbore guns. This specialized munition not only ensures high muzzle velocity for kinetic energy rounds designed to neutralize armored vehicles but also enhances the indirect fire capabilities of MBTs, addressing dynamic operational requirements.

Strategic Impact of Indirect Fire

Historically, main battle tanks have relied on direct engagement methods. However, tactical scenarios increasingly demand the ability to engage targets at extended ranges without relying solely on traditional artillery support. The Vulcano, capable of achieving speeds exceeding 1,700 meters per second, can strike targets beyond 4 kilometers—far surpassing standard operational range expectations. This potential allows for reduced-range training rounds that simplify live-fire exercises while minimizing safety concerns associated with extensive training areas.

Key advantages of the Vulcano 120 include:

• Rapid Target Engagement: By effectively utilizing the tank’s primary weapon for indirect fire, forces can engage fleeting targets swiftly, a crucial factor when engaging moving or temporary threats.
• Integration of Drone Capabilities: Recent discussions within the Italian Army Cavalry School highlighted the dual use of drone technology in streamlining targeting cycles, particularly for reconnaissance units often deprived of organic fire support.

Technological Integration and Development

At a recent event in La Spezia, Leonardo unveiled the Vulcano 120, enhancing its existing family of precision munitions developed for 155 mm and 127 mm artillery systems. According to Mauro Pellegri, Senior Vice President of the Ammunition Line of Business:

• “The Vulcano 120 is designed for non-line-of-sight engagements across all platforms utilizing 120 mm smoothbore guns. Being ITAR-free simplifies export logistics, which is significant for international partnerships.”

The Vulcano 120’s semi-active laser (SAL) guidance system marks a transformative step, allowing the projectile to be directed toward targets designated by external laser sources, whether onboard a UAV or on the ground via a targeting team such as a Joint Terminal Attack Controller (JTAC).

Enhanced Projectile Design and Effectiveness

The Vulcano round’s aerodynamics is engineered to optimize range, featuring a sub-caliber profile that not only enhances stability in flight but also maximizes kinetic energy upon impact with a specialized warhead designed for effectiveness against heavily armored targets.

Testing has focused on validating the penetration capabilities of these rounds against Rolled Homogeneous Armor (RHA), particularly on the turret roofs of modern tanks. Pellegri emphasizes that the residual kinetic energy of the Vulcano 120 greatly surpasses traditional air-to-ground munitions, like the 30×173 mm rounds used by the A-10 Thunderbolt.

Conceptualizing Indirect Fire Roles

Adopting the Vulcano 120 necessitates a doctrinal shift within land forces, requiring structural reorganization of tactical units. Considerations include:

• Integrated Engagement: Tanks act solely as platforms to deliver munitions upon request.
• Standalone Engagement: Utilizing internal sensors, tanks can independently operate without external directives.

Future Developments: Imaging Infrared Seekers

Looking ahead, Leonardo plans to advance the Vulcano technology further with the development of an Imaging Infrared (IIR) seeker. This will enable autonomous target identification, independent of external designators. As highlighted by Pellegri, new generations of sensors will enhance operational effectiveness, particularly in complex land environments.

Conclusion: The Future of Tank Warfare

The integration of the Vulcano 120 mm into existing tank systems signifies a strategic leap toward versatile, multi-role capabilities for modern armored units. These advances not only extend the operational envelope of tanks but also redefine the role of artillery and infantry in combined arms operations. As battlefield technology continues to evolve, maintaining a competitive edge will depend on integrating such innovations while fostering a comprehensive understanding of evolving combat doctrines.

In summary, the Vulcano 120 mm artillery round represents a significant enhancement, providing tanks with the means to engage a diverse array of targets effectively. As military operations increasingly focus on speed and accuracy, the introduction of guided munitions like Vulcano provides a critical tool for military planners in adapting to the future of warfare.
