Introducing Sceptre: A New Era in Artillery

Sceptre is a 155mm precision-guided artillery munition that leverages ramjet propulsion technology to achieve speeds of Mach 3.5 and strike targets at distances of up to 150 kilometers. Unlike traditional artillery shells, which rely solely on explosive propulsion, Sceptre incorporates a liquid-fueled ramjet engine, allowing it to sustain high-speed flight and maintain accuracy even in GPS-contested environments.

Key Features of Sceptre

  • Extended Range: Capable of reaching targets up to 150 km away, significantly surpassing conventional artillery shells.

  • High-Speed Flight: Achieves speeds of Mach 3.5, ensuring rapid target engagement.

  • Precision Targeting: Features a circular error probability (CEP) of less than 5 meters, even in GPS-denied environments.

  • Advanced Guidance System: Utilizes GPS and inertial navigation, enhanced by AI-powered error correction algorithms.

  • Modular Design: Built with an open architecture, allowing for future upgrades and integration with advanced targeting systems.

  • Compatibility: Fully compatible with NATO-standard 155mm artillery platforms, requiring no modifications to existing systems.

How Sceptre Works

Sceptre’s ramjet propulsion system activates post-launch, sustaining high-speed flight over extreme distances. Unlike traditional artillery rounds, which lose velocity and accuracy over long distances, Sceptre maintains consistent thrust, ensuring precise impact even in electronic warfare environments.

During flight, onboard AI synchronizes GPS and inertial measurement data, continuously refining the munition’s trajectory. If needed, multiple Sceptre rounds can communicate mid-flight, further improving targeting precision. This capability makes Sceptre particularly effective in high-intensity combat scenarios, where traditional artillery systems struggle with accuracy and range limitations.

Strategic Implications

The introduction of Sceptre marks a transformational shift in artillery warfare. With peer threats intensifying and battlefield survivability becoming increasingly challenging, long-range precision munitions are more critical than ever. Sceptre provides NATO and allied forces with a cost-effective, agile, and modular deep-strike capability, reducing reliance on expensive missile systems while maintaining high-impact precision.

Additionally, Sceptre’s ability to operate in GPS-denied environments addresses a growing concern in modern warfare—electronic warfare countermeasures. Traditional GPS-guided munitions have faced challenges against Russian electronic warfare tactics, making AI-enhanced targeting solutions like Sceptre indispensable.

Future Prospects and Deployment

Tiberius Aerospace has already conducted live-fire tests in the United States, using M777 howitzers to validate Sceptre’s performance. The company aims to certify the munition for deployment by Q4 of 2025, positioning it as a credible alternative to existing long-range precision strike systems.

With military forces worldwide reassessing their artillery capabilities, Sceptre’s cost-efficiency, adaptability, and precision make it a disruptive force in modern warfare. As defense technology continues to evolve, innovations like Sceptre will play a pivotal role in shaping the future of artillery combat.

Tiberius Aerospace’s Sceptre ramjet munition represents a significant leap forward in artillery technology. By combining extended range, high-speed flight, and AI-enhanced precision, Sceptre offers unmatched capabilities for modern battlefield operations. As military forces seek more effective and adaptable solutions, Sceptre stands out as a revolutionary advancement in long-range precision artillery.

Boeing secured a $61.2 million contract from the U.S. Department of Defense to deliver additional High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC) modules for the Navy’s fleet of P-8A Poseidon aircraft. This development marks a notable shift in the operational role of the Poseidon platform, transitioning it from a traditional maritime patrol aircraft to a more versatile strike-capable system. P-8A Poseidon. navair.navy.mil The HAAWC system is designed to enhance the deployment of the Mark 54 lightweight torpedo by enabling launches from cruising altitudes. This is achieved through a winged kit that includes foldable wings and a GPS-guided navigation unit, allowing the torpedo to glide toward its target before deploying a parachute for water entry. The system draws on technologies previously developed for the Joint Direct Attack Munition (JDAM) and the SLAM-ER missile, integrating lessons from long-range guided bomb programs. Operationally, the ability to launch torpedoes ...

The U.S. Air Force’s FY2026 budget proposal includes a notable initiative aimed at enhancing the survivability and operational flexibility of its aerial refueling fleet, specifically the KC-135 Stratotanker. Originally developed in the 1950s, the KC-135 has long served as a cornerstone of the Air Force’s global refueling operations. However, the evolving nature of modern warfare—characterized by contested airspaces and advanced anti-access/area denial (A2/AD) systems—has prompted a reevaluation of the platform’s defensive capabilities. KC-135. 507arw.afrc.af.mil Central to this proposed upgrade is the integration of a Drone Delivery Mechanism (DDM), a system designed to deploy small unmanned aerial vehicles (UAVs) from the KC-135 in flight. This concept represents a shift from passive to active defense strategies for support aircraft. Traditional countermeasures such as chaff, flares, and infrared jamming systems like LAIRCM have provided limited protection against increasingly sop...
