Collaborative combat aircraft · Wiki

Collaborative combat aircraft (CCA) are a class of large, jet-powered uncrewed aircraft that an air force plans to fly together with crewed fighters. The term is used most precisely for the United States Air Force programme of that name, although other air forces use related labels such as autonomous collaborative platforms or loyal wingman concepts. A CCA is distinct from a small tactical drone: it is a sizeable, reusable aircraft bought as a fleet and supported over many years.

What the US programme describes

The Congressional Research Service describes CCAs as uncrewed aircraft intended to fly alongside crewed fighters in contested airspace, with potential missions that include air-to-air and air-to-ground roles, electronic warfare, targeting, and intelligence, surveillance and reconnaissance. They are part of the Next-Generation Air Dominance family of systems and are meant to supplement crewed aircraft, not replace them. Officials have estimated that each CCA would cost about a third as much as a crewed fighter, which is the basis of the argument for buying them in larger numbers. A 2023 notional plan referred to around 1,000 CCAs paired with roughly 500 advanced crewed fighters, though quantities have depended on funding and requirements work.

The programme is organised in increments. The Air Force has said that two designs from different companies were designated YFQ-42A and YFQ-44A in 2025 under Increment 1, and both have been in flight testing. Increment 2 is at an early stage and a wider group of companies may compete for it.

How the concept works

A CCA is expected to rely on software that lets it follow tasks given by a human pilot, rather than being flown continuously by a remote operator. Human involvement in operations remains part of the design. This depends on secure communications, a shared tactical picture and onboard functions such as sensor fusion, so that the crewed aircraft can direct several uncrewed ones without a heavy workload. Autonomy software is treated as a separable component, and the Air Force has described a competitive marketplace for mission autonomy.

Other national approaches

The United Kingdom’s Royal Air Force published an Autonomous Collaborative Platforms strategy in 2024, setting out how such aircraft could be acquired for future needs. Other European and Asia-Pacific programmes pursue comparable concepts with their own timelines.

Why it matters for defence technology

CCAs move part of combat aviation capability into software and mission systems, and make sustainment, production rates and basing a bigger programme question than for a single crewed type. The Congressional Research Service lists several open issues: how many to buy, how to oversee development, interoperability with other aircraft, the risks and benefits of greater autonomy, and whether the Air Force has planned for producing, storing, transporting and sustaining large numbers.

What to watch

Key indicators include Increment 2 decisions, the structure of the autonomy software market, weapons and sensor integration milestones, allied participation, and the policy approach to human control. Related systems-level topics are uncrewed systems in general and command and control for mixed crewed and uncrewed formations.
