An Unmanned Combat Air Vehicle (UCAV) is a remote-controlled drone that contains armaments such as firearms, explosives, or missiles. The additional weight of such arms limits a UCAV's endurance compared to an unarmed UAV.
It functions in a similar manner to the TV Guided Missile, allowing for users to see through its onboard camera and steer the UCAV towards enemies. Unlike the TV Guided Missile there is no delay in the turning movement sent to it. Its launch tube first has to be set down (like the M224 Mortar), whereupon it immediately launches. The user then steers it like an air vehicle. By pressing , the UCAV's airburst explosive can be detonated once unlocked by completing the assignment I'm Dynamite. The airburst warhead for UCAV is significantly more deadly to infantry than standard UCAV warhead, it can easily score multi-kills.
The UCAV has a maximum range of about 400 meters—traveling roughly 40 meters per second for 10 seconds—after which contact is lost with the drone. After losing contact the drone will explode. After the patch it reloads on its own after about 60 seconds without the need for an ammo box. Its explosive power and radius are about the same as a single C4 pack, however it only deals 40 damage to vehicles.
- The UCAV in Battlefield 4 is modeled after the AeroVironment Switchblade.
- The UCAV originally took 45 seconds to reload after use. This was later changed to 60 seconds following the Spring 2015 patch.
