An aircraft drive shaft that includes an outer shaft with a first diameter that is configured to couple a first gearbox and a second gearbox to provide power transfer between the two gearboxes. An inner shaft that is concentric with the outer shaft and has a second diameter that is configured to provide structural support to the outer shaft. A gap is located between an outer peripheral surface of the inner shaft and an inner peripheral surface of the outer shaft. The gap has a size from the outer peripheral surface to the inner peripheral surface that is at least as large as a largest ballistic projectile cross-section size that the aircraft is expected to encounter on an upcoming mission. A sleeve is located at least at a first end of the outer shaft and connects the outer shaft to the inner shaft.
