The recent test of the Scorpio-XR extended-range artillery projectile by BAE Systems in collaboration with the US Army marks a significant development in the army’s long-range precision fires modernization initiative. Multiple successful shots were fired from a 155mm howitzer, outperforming initial test objectives and confirming the projectile’s compatibility with the widely utilized 155mm, 52-caliber howitzers as per the Joint Ballistics Memorandum of Understanding among NATO allies.
The tests demonstrated the Scorpio-XR’s capability to guide to targets with remarkable precision, achieving impacts at distances that surpass the range of existing cannon rounds. Formerly known as the XM1155-SC, this maneuverable cannon-launched projectile is engineered to deliver precise strikes at ranges exceeding those of current 155mm munitions, effectively extending the operational reach of division-level artillery units.
Earlier trials indicated successful engagements with various howitzer systems, ranging from 39- to 58-caliber barrels. In commentary on the achievement, BAE program director for Combat Systems Development, Jason Casciotti, emphasized the ongoing effort to advance precision in long-range artillery systems, expressing a commitment to building on the project’s success and exploring its implications for the future of artillery technology.
The Scorpio-XR is part of an extensive initiative by the US Army, encapsulated in the Extended Range Cannon Artillery (ERCA) program, aimed at improving the range and accuracy of tube artillery systems. This effort is intended to bridge the gap between traditional artillery capabilities and modern precision missile systems, allowing ground forces to engage targets deeper within enemy territory with increased efficiency.
Although further testing and development are anticipated, the latest results suggest that the Scorpio-XR could play a vital role in the army’s future long-range fires arsenal, complementing other advanced munitions and sensor systems.
Initially announced in April, BAE Systems is developing the Scorpio-XR under the Hypervelocity Projectile program, with capabilities to cover over 70 kilometers (43 miles). This extended range outstrips the existing Excalibur projectile, which currently allows conventional artillery to reach distances of up to 40 kilometers (25 miles) with 39-caliber tubes, 50 kilometers (31 miles) with 52-caliber, and 70 kilometers (43 miles) with 58-caliber artillery.
The Scorpio-XR features a significantly reduced flight time and is designed to effectively engage both fixed and moving targets in contested environments. Its development is supported by a $72.5 million contract signed in May 2023, which enables the US Army to collaborate with the UK-based defense manufacturer for continued research and evolution of advanced precision-guided artillery munitions.
Moreover, the compatibility of the Scorpio-XR with existing gun systems allows for modernization efforts without incurring substantial costs or facing extensive training challenges associated with new systems. Once operational, the Scorpio-XR is poised to enhance the military’s anti-access/area-denial strategy, marking its importance in contemporary defense capabilities.
