E-3D

The E-3D variant of the AWACS is operated by a crew of 18, drawn from RAF and exchange personnel; it is configured to meet United Kingdom’s operational requirements, to maintain interoperability with Allied E-3 fleets and to maximise interchangeability with the E-3A.  The E-3D Component has six E-3D aircraft; the originally procured 7th aircraft is now used as a ground based emergency trainer. The E-3D is most easily identifiable from the E-3A by the larger engine design, the refuelling probe and the presence of wingtip pods. The E-3D operates at a similar altitude to the E-3A; around 10 km, although the efficiency of its upgraded engines gives it a slightly increased maximum operating altitude.
