Collaborative combat aircraft (CCA), is a US program for unmanned combat air vehicles (UCAVs) and considered broadly equivalent to loyal wingman. CCAs are intended to operate in collaborative teams with the next generation of manned combat aircraft, including sixth-generation fighters and bombers such as the Northrop Grumman B-21 Raider.[1] Unlike the conventional UCAVs, the CCA incorporates artificial intelligence (AI), denoted an "autonomy package", and is capable of surviving on the battlefield. It is still expected to be much lower-cost than a manned aircraft with similar capabilities.[2] The US Air Force plans to spend more than $6 billion on its Collaborative Combat Aircraft (CCA) programs over the next five years (2023 to 2028).[3][4] The success of the CCA program could lessen the need for additional manned squadrons.[5][6]
