A hard defensive device built into the variable fighters beginning in the 2030s. The standard bulletproof, anti-projectile shield is built as the center rear dorsal fuselage of a variable fighter which is then deployed for use in GERWALK/Battroid configurations following transformation of the left arm. The anti-projectile shield is typically a defense option of last resort, used to intercept incoming attacks that cannot be shot down or avoided. The anti-projectile shield has proved an indispensable feature since introduced with the VF-11 Thunderbolt and is standard on the YF-19/VF-19 Excalibur, the YF-21/VF-22 Sturmvogel II, the VF-25 Messiah and the VF-27 Lucifer.
