Unmanned combat aerial vehicle

An unmanned combat aerial vehicle (UCAV), also known as a combat drone, fighter drone or battlefield UAV, is an unmanned aerial vehicle (UAV) that carries aircraft ordnance such as air-to-surface missiles, anti-tank guided missiles (ATGMs), and/or aerial bombs on hardpoints or within weapons bay, allowing it to perform tactical attacks known as drone strikes. Some new UCAVs gained the capability for beyond-visual-range air-to-air combat when retains the drone strike capability. UCAVs are used for intelligence, surveillance, target acquisition and reconnaissance, attacking high-value targets and prolonged loitering before needing to return to base, unlike loitering munitions and one-way attack drones, which are single-use drones made for physically ramming into a target and exploding on impact; or surveillance drones, which are unarmed drones used only for aerial reconnaissance and gathering intelligence. In March 2026 the British government indicated that it had aerial minesweeping drones and was considering deploying them in the strait of Hormuz.

Aircraft of this type have no onboard human pilot, but are usually under real-time remote control by human operators, with varying levels of automation. As the operator runs the vehicle from a remote terminal via radio control, equipment necessary to support an on-board human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft for the same payload. Many countries have operational domestic UCAVs, and many more have imported fighter drones or are in the process of developing them.

Technological advancements are rapidly expanding the capabilities of UCAVs with a primary focus on enhanced autonomy and sophisticated artificial intelligence (AI). Several UCAVs can perform complex functions such as autonomous sensor fusion, real-time target identification and dynamic mission re-planning reducing the cognitive load on human operators. This evolution is central to modern network-centric warfare as UCAVs seamlessly integrate into combined architectures. By sharing data across platforms from satellites to ground units they create a fused, comprehensive battlespace picture that enables dramatically faster decision cycles which is a critical advantage in modern strategy. A significant new doctrinal is embodied in the development of loyal wingman capable UCAVs, designed to operate in collaborative teams with manned fighter jets. These drones can perform high-risk missions like electronic attack, forward reconnaissance or weapons delivery thereby shielding human pilots and acting as force multipliers. As global militaries increasingly invest in and deploy unmanned systems an arms race in countermeasures is concurrently accelerating. This includes the development of advanced electronic warfare (EW) suites, directed-energy weapons and anti-drone systems to disrupt, deceive or destroy UCAVs. This arms race ensuring that the battlefield of the future will be defined by this competition between UCAV platforms and the measures designed to defeat them.
