General Atomics Joins Army's ERAP, Boosting Long-Range Firepower

📅 June 16, 2026 ⏱ 4 min read 📰 Source: Breakingdefense 👁 5 views

General Atomics Electromagnetic Systems has secured a pivotal development contract for the Army's Extended Range Artillery Projectile (ERAP) program, joining two other defense giants. This award solidifies a multi-vendor approach to delivering next-generation 155mm projectiles capable of striking moving targets at extended distances. The initiative aims to equip ground forces with enhanced precision against critical assets like armored vehicles and maritime threats. This expansion of advanced long-range precision fires reflects a strategic imperative driven by contemporary conflict zones, where the ability to achieve standoff lethality is paramount. The program underscores a broader military trend towards integrating sophisticated guidance systems into conventional munitions to counter increasingly mobile and protected adversaries.

Key Intelligence Points

General Atomics Electromagnetic Systems secured a contract for the Army's ERAP program, becoming the third major defense prime to join the effort to develop extended-range 155mm artillery.
The ERAP, or XM1155, program seeks a 155mm projectile capable of accurately engaging mobile targets such as armored fighting vehicles and naval assets at ranges exceeding sixty-five kilometers.
GA-EMS joins General Dynamics Ordnance and Tactical Systems, which fields the Vulcano system, and BAE Systems in this critical initiative to bolster the Army's long-range fires.
The Army anticipates initial operational capability for these new projectiles by fiscal year 2030, mandating compatibility with both current and future howitzer platforms.
Vendor solutions integrate advanced guidance systems, including GPS, semi-active laser, and far-infrared seekers, to ensure precision targeting even amidst GPS jamming or contested environments.

Intelligence Briefing

Why this matters: The multi-vendor strategy for ERAP is crucial, fostering competition and accelerating the delivery of vital long-range precision capabilities. This directly enhances the Army's ability to conduct effective deep-strike operations, suppressing enemy air defenses, artillery, and logistics at greater standoff. For policymakers, it signifies a commitment to modernizing conventional deterrence, particularly relevant in potential peer-conflict scenarios where rapid, accurate engagement of high-value, mobile targets is essential for battlefield dominance.

WASHINGTON — General Atomics Electromagnetic Systems (GA-EMS) announced it was awarded a contract to develop a 155-mm projectile for the Army’s Extended Range Artillery Projective (ERAP) program, joining General Dynamics Ordnance and Tactical Systems (GD-OTS) and BAE Systems who were ly awarded for the program.

“Over time we have expanded our production capacity, advanced our scaling innovations, and reinforced our readiness to design, qualify, produce, and deliver ‑generation munitions.” Scott Forney, president of GA-EMS said in a company release Friday. “This award confirms that GA‑EMS is ready to deliver extended‑range, precision capabilities that give the warfighter unmatched standoff range and lethality.”

The ERAP program, also referred to as the XM1155 program, was kickstarted in 2024 and is the Army’s initiative to find a 155-mm projectile that can hit moving targets at ranges beyond 65 km (40 miles) such as self-propelled howitzers, infantry fighting vehicles, multiple rocket launchers, tanks and maritime targets. The XM1155 was ly being developed under the now scrapped Extended Range Cannon Artillery (ERCA) program.

According to an Army request for information from 2024, the service is seeking solutions that can reach Initial Operational Capability (IOC) fielding by fiscal year 2030 and begin low-rate production by the second quarter of FY29. The solutions must also be compatible with existing and future howitzers, the Army later stated, with the latter referring to the Army’s current self-propelled howitzer competition which the service is expected to award month.

GA-EMS’ announcement comes a week after GD-OTS announced it was also awarded a developmental contract under the ERAP program for its Vulcano 155 Guided Long Range system. The Vulcano is developed by Italian firm Leonardo Electronics and German firm Diehl Defence. GD-OTS is in charge of “transitioning” the production lines into the United States, per the company’s release.

“The system can achieve [a] range of up to 70 kilometers with high precision, enabled by advanced aerodynamics, GPS guidance and a Semi-Active Laser (SAL) terminal seeker,” GD-OTS’ release from June 5 read. “In addition to the SAL seeker configuration, the ammunition is also available with advanced Far-Infra Red seeker capable of engaging Sea Targets. Both configurations can provide precision engagement even in GPS-contested environments.”

Editorial Analysis

The ERAP program represents a fundamental shift in land warfare, moving beyond static targets to prioritize the destruction of highly mobile and hardened enemy assets at extreme ranges. This capability fundamentally alters the risk calculus for adversaries, forcing them to operate further from the front lines or face swift, precise reprisal. Integrating advanced seekers like semi-active laser and infrared ensures operational effectiveness in environments where GPS might be denied or degraded, a critical consideration for future conflicts. The competition among three experienced defense contractors is set to drive innovation and robustness in a key area of conventional deterrence.

This initiative echoes historical arms races in artillery development, yet it marries traditional ballistic principles with contemporary guided missile technology. It aligns with a broader trend across NATO and allied forces to extend the reach and accuracy of existing platforms, rather than solely investing in entirely new systems. For the security community, the successful fielding of ERAP will significantly enhance joint force lethality and provide commanders with unparalleled flexibility in shaping the battlefield against evolving threats, from armored columns to agile maritime targets.
