UAV-45s have a small airframe (smaller than even that of an F-16C Fighting Falcon), which is equipped with variable sweep wings, dual vertical stabilizers, and a top-mounted intake. Their weaponry is limited to a single machine gun, since they are too small to carry missiles; likewise, they have very little armor. Individually, one UAV-45 is highly vulnerable to enemy attack.
However, the lack of offensive and defensive power is compensated by the fact that UAV-45s are deployed by dozens at a time, easily swarming enemy fighters. They also have high maneuverability, able to perform post-stall maneuvers that defy the laws of aerodynamics and physics.
The CFA-44 Nosferatu has a "master unit" that controls the UAV-45s. This control unit is highly vulnerable to combat damage suffered directly by the CFA-44; consistent damage could cause a temporary loss of functionality or a self-destruct command to activate on some of the drones. If the master unit completely fails or is entirely destroyed, all remaining UAV-45s self-destruct.
Very little history is known on the UAV-45s, but it is believed that they were developed simultaneously with the CFA-44 Nosferatu.
Their only known combat deployment was during Operation Free Gracemeria, when a massive swarm of UAV-45s were utilized by Ilya Pasternak as he used a CFA-44 to attempt to hold off the Republic of Emmeria Air Force. All of the drones and the CFA-44 were destroyed by Garuda Team. 
- The UAV-45 does not have a consistent proper name. Both "Malgebolg" and "Malebolge" are used - the former in the mission subtitles by Pasternak if all of them are shot down, the latter in the Ace Combat 6: Fires of Liberation Original Soundtrack.
- The canard positions and the nose/fuselage of the craft bear a slight resemblance to the ADF-01 FALKEN.
