As90Edit
The AS90 Braveheart is a British 155 mm self-propelled howitzer that has served with the United Kingdom armed forces since the late 1990s. Built to deliver heavy artillery with mobility, it embodies a defense posture that emphasizes credible deterrence, rapid response, and strong alliance assurance. Its existence reflects a policy preference for capable, independent heavy firepower that can be brought to bear in conventional warfare as well as in support of coalition operations.
Across several decades, the AS90 has been a focal point in debates about defense investment, force structure, and modernization. Proponents argue that a robust, self-propelled artillery capability remains essential for modern land warfare, providing long-range fires, rapid emplacement, and survivability on a high-intensity battlefield. Critics have stressed budget discipline, argued for more versatile or lighter systems, and questioned the pace and value of certain upgrades. The discussion around the AS90 sits at the intersection of national sovereignty, alliance commitments, and the overall balance of military spending with other public priorities.
History
The AS90 was developed in the closing years of the 20th century as part of the United Kingdom's effort to modernize its artillery fleet. It was produced by a consortium that included Vickers Defence Systems (which went through several corporate evolutions as defense procurement matured) and later became part of the broader BAE Systems portfolio. The aim was to replace older self-propelled and towed guns with a capable, vehicle-mounted system that could deliver heavy rounds with speed and accuracy on the modern battlefield.
The program emphasized integration with contemporary fire-control systems, digital data links, and interoperability with allied forces. The result was a platform that could be deployed with relatively short readiness times and that could operate in conjunction with other arms in a coordinated attack or suppression of enemy artillery. The AS90 quickly became a core piece of the Royal Artillery's heavy-fire support capability, and it participated in training and operations that tested its performance in conditions ranging from desert to temperate climates.
Design and capabilities
Configuration: The AS90 is a self-propelled artillery system designed to deliver 155 mm ammunition from a turret-mounted gun. It relies on a combination of mobility, protection, and automated loading to maintain a steady rate of fire on target.
Armament and fire control: The gun is paired with an integrated fire-control system, enabling rapid target acquisition, data-sharing with command networks, and coordinated fires across multiple vehicles and batteries. The platform is designed to use standard NATO 155 mm ammunition and charge combinations, allowing it to interoperate with allied stocks and supply chains.
Mobility and protection: The vehicle is built to operate across varied terrains and to maneuver into a supported firing position under the protection of its armor and self-defense systems. Its mobility supports rapid response to changing battlefield conditions and the ability to reposition after firing.
Crew and logistics: The AS90 is designed for a relatively lean crew and features automated elements to streamline loading and ammunition handling. It is part of a broader artillery system that emphasizes networked operations and joint fires with infantry, armor, and air assets.
Variants and upgrades: Over time, the platform has undergone modernization efforts intended to extend its service life and improve reliability, accuracy, and compatibility with evolving battlefield networks. These improvements have focused on electronics, sensors, and maintenance efficiencies, with the aim of keeping the system relevant in a changing strategic environment.

Operational history
Since entering service, the AS90 has formed a key component of the UK’s heavy-fire support. It has participated in training exercises and, in line with alliance commitments, has been integrated into multinational operations and deployments where high-volume artillery fires are advantageous. Its deployment patterns have reflected a philosophy that values predictable, long-range fires as a deterrent and as a force multiplier in conventional campaigns.
The platform’s performance has been assessed in terms of readiness, reliability, and the ability to sustain operations under combat stress. As with any such system, the AS90’s employment has been governed by doctrine, logistical support, and overarching strategic objectives. The weapon’s presence within the Royal Artillery has influenced force structure decisions and the development of complementary capabilities, including improved sensors, communications, and air- and land-based reconnaissance that enable precise, timely fires.
Upgrades and variants
A recurring theme in the AS90 program has been modernization rather than wholesale replacement. Upgrades have typically focused on digital fire-control interoperability, reliability improvements, and maintenance simplification. These measures are designed to keep the system capable of meeting contemporary requirements while extending its useful life within a broader, adaptable force structure. The aim is to preserve the advantages of a heavy, self-propelled artillery platform — reach, stability, and suppressive capability — while integrating with newer command-and-control ecosystems and logistics pipelines.
In the broader context of defense procurement, the AS90 conversation intersects with choices about whether to pursue continued upgrades to existing systems, to adopt newer self-propelled platforms from allied partners, or to shift emphasis toward lighter, more mobile systems that can keep pace with rapidly changing operational concepts. Proponents argue that the AS90’s continued relevance is anchored in its proven fires, while skeptics push for alternatives that might deliver similar or greater effects with different trade-offs in weight, cost, and interoperability.
Controversies and debates
Cost and value: Debates about the AS90 often center on the cost of procurement, upgrades, and lifecycle support. Critics have questioned whether resources could be better allocated to a broader mix of capabilities, while supporters contend that a credible, scalable artillery capability is central to deterrence and to a balanced defense budget.
Compatibility with new concepts: As doctrinal emphasis shifts toward network-centric warfare and joint fires, questions arise about how well heavy SPGs like the AS90 integrate with evolving surveillance, targeting, and precision-strike paradigms. Proponents point to the system’s ability to operate within modern networks, while critics caution that older platforms must be weighed against potentially more flexible alternatives.
Role in force structure: The debate over the AS90 reflects wider discussions about the optimal mix of heavy, medium, and light forces. Some argue for a continued emphasis on heavy indirect fire as a cornerstone of national defense, especially in traditional large-scale combat scenarios. Others advocate reallocating funds toward rapid-reaction forces, improved air and cyber capabilities, or more agile artillery solutions that can be deployed quickly and at a lower logistical cost.
Political framing of defense spending: In public discourse, defense procurement often becomes entangled with broader political debates. Those cautious about public expenditures emphasize accountability and opportunity costs, while defenders argue that robust military capabilities are a rational investment in national security and alliance credibility. Critics of what they term “overhangs” in defense budgets often label some procurement choices as imprudent; supporters respond that stabilizing deterrence and fulfilling alliance commitments require sustained, predictable funding.
