U.S. Army Award Positions GDOTS to Deliver Vulcano-Derived 155mm Projectile for Precision Fires Beyond 70 Kilometers.

General Dynamics Ordnance and Tactical Systems has secured a U.S. Army contract for a 155mm Extended Range Artillery Projectile, the company confirmed on June 5, 2026, giving American tube artillery a path to strike targets at up to 70 kilometers with precision effects. Based on the Vulcano guided round developed with Diehl Defence and Leonardo, the award supports the Army’s push to regain artillery overmatch through smarter ammunition that can reduce exposure to counter-battery fire.

The projectile combines long-range aerodynamic performance with guided flight and optional terminal seekers, including Semi-Active Laser guidance for stationary or moving targets and a Far-Infrared seeker for maritime engagement. This gives U.S. artillery units a potential bridge between current cannon systems and future long-range fires, adding a lower-cost precision layer for counter-fire, deep strike, and coastal defense missions.

On June 5, 2026, General Dynamics Ordnance and Tactical Systems confirmed that it had received a contract for the U.S. Army’s next-generation 155mm Extended Range Artillery Projectile, marking a new step in Washington’s effort to regain artillery overmatch through smarter ammunition rather than only longer barrels. Derived from the Vulcano 155 Guided Long Range system developed with Diehl Defence and Leonardo, the projectile brings a European combat-proven precision artillery concept into a U.S. Army modernization track shaped by the need for deeper, faster, and more survivable fires. The development is particularly significant because it comes as modern battlefields have shown that artillery effectiveness is no longer measured only by volume of fire, but by the ability to strike high-value targets at extended range with fewer rounds, lower exposure to counter-battery fire, and greater resilience in GPS-contested environments.

The new projectile is presented by GDOTS as a target-seeking precision artillery munition derived from the Vulcano 155 Guided Long Range family, a sub-caliber 155mm ammunition designed to increase range and accuracy while remaining compatible with existing artillery handling and firing systems. This design choice is central to its operational value: rather than relying only on a heavier propelling charge or a new cannon, the projectile uses reduced aerodynamic drag, guided flight, and terminal seeker options to push conventional artillery into a range class normally associated with more expensive rocket and missile systems. The Vulcano family includes unguided Ballistic Extended Range and Guided Long Range variants, with the guided version using advanced aerodynamics, inertial and GPS guidance, and optional terminal seekers. In the configuration highlighted by GDOTS, the munition can reach up to 70 kilometers and can be equipped with a Semi-Active Laser terminal seeker for precision engagement of stationary and moving targets. A Far-Infrared seeker configuration is also available for sea-target engagement, giving the projectile a potential role beyond traditional land fire support and opening the door to coastal defense missions in regions such as the Baltic Sea, the Black Sea, and the Indo-Pacific island chains.

The contract also appears to fit into a wider U.S. Army Extended Range Artillery Projectile effort rather than a single isolated procurement. The Defense Ordnance Technology Consortium awards listing identifies an April 2026 “Vulcano-ASC 155mm Extended Range Artillery Projectile” initiative awarded to General Dynamics-OTS with a project value of $37.86 million. The same listing also includes separate ERAP-related awards to General Atomics and BAE Systems Land & Armaments, indicating that the Army is assessing several industrial and technical approaches to deliver longer-range 155mm ammunition. This broader context matters because it suggests that the U.S. Army is not only seeking one new shell, but also trying to define the next layer of precision cannon fires after years of investment in both extended-range guns and guided ammunition. It also points to a possible shift in U.S. artillery modernization: after the technical difficulties associated with developing new extended-range cannon systems, the Army appears to be placing greater emphasis on ammunition-led range growth, where smarter projectiles can improve battlefield reach faster than the full introduction of new artillery platforms.

One of the main advantages of the Vulcano-derived projectile is its ability to extend the operational envelope of tube artillery while preserving the relatively low logistical footprint of 155mm ammunition. Traditional high-explosive artillery shells remain useful for area fire and suppression, but their effectiveness decreases as range increases and target location errors grow. Rocket-assisted or base-bleed projectiles can fly farther, but they do not automatically solve the accuracy problem. The Vulcano approach is different: its sub-caliber body reduces drag, its guided flight profile improves precision, and its terminal seeker options allow target discrimination at the end of flight. This makes it suitable for high-value targets such as air defense systems, command posts, artillery batteries, logistics hubs, armored vehicles, radar sites, and, in the Far-Infrared configuration, selected maritime targets in coastal environments.

Compared with the M982 Excalibur, which remains the benchmark U.S. 155mm precision-guided artillery projectile, the GDOTS solution should be understood as a complementary capability rather than a simple replacement. Excalibur is already integrated into U.S. and allied artillery units and is valued for first-round precision against fixed coordinates, especially when target location is already established and the mission requires controlled effects with limited collateral damage. The Vulcano-derived projectile follows a different operational logic by combining extended aerodynamic performance, seeker-based terminal engagement, and a wider target set. Its value is not only in reaching farther, but in giving artillery units the ability to engage targets that may move, relocate, or operate in GPS-contested environments, including selected maritime threats when using the Far-Infrared seeker configuration.

This distinction is important for the U.S. Army because artillery modernization is no longer defined only by the gun, but by the relationship between barrel length, ammunition design, fire-control integration, and the targeting network behind each shot. Today’s U.S. tube artillery force is still centered on systems such as the M777 and M109A7 Paladin, while future long-range cannon concepts are expected to rely on longer-barrel architectures and more efficient projectiles. A Vulcano-derived ERAP could therefore act as a bridge between the current fleet and future artillery systems, allowing the Army to increase tactical reach before a new generation of platforms is fully fielded. In that sense, the GDOTS projectile is not simply another guided shell, but part of a broader shift toward ammunition-led overmatch, where smarter 155mm rounds help restore range, survivability, and precision in high-intensity warfare.

The contract reflects a shift in how the U.S. Army may recover range advantage after the technical challenges encountered by the Extended Range Cannon Artillery effort. Rather than relying only on a new 58-caliber cannon, the Army is continuing to pursue munitions that can extend reach from existing and future artillery systems. This matters tactically because a 70-kilometer-class guided projectile allows batteries to operate farther from enemy counter-battery threats while engaging targets that previously required rockets, missiles, or air-delivered weapons. In Europe, such a capability would strengthen NATO’s ability to conduct precision counter-fire and disrupt rear-area logistics in a dense artillery environment. In the Indo-Pacific, the Far-Infrared seeker option could support distributed land forces operating from islands or coastal positions, where artillery could contribute to sea-denial missions against landing craft, patrol vessels, or logistics ships. It would not replace anti-ship missiles, but it could add a lower-cost, magazine-deep layer to joint maritime defense.

The GDOTS award for a Vulcano-derived 155mm Extended Range Artillery Projectile marks a significant step in the U.S. Army’s search for longer-range, more precise, and more adaptable cannon fires. Its value is not limited to the 70-kilometer range figure. The program links European munition maturity with U.S. production capacity, adds seeker-based engagement options against moving and maritime targets, and supports a more flexible artillery force able to operate under counter-battery and electronic warfare pressure. If the Army can integrate the projectile across current and future 155mm systems, connect it to resilient targeting networks, and scale production in meaningful quantities, ERAP could become one of the most important bridges between conventional artillery and the missile-centric precision fires architecture now shaping modern land warfare.
