Recognition

Externally, the C4 and C5 versions of the Hercules are almost identical to the existing C1s and C3s currently in service. On the newer aircraft however, the refuelling probe (when fitted) is mounted on the left-hand side of the aircraft above the cockpit. The new engines also have six-bladed propellers as opposed to four on the older aircraft and the new aircraft do not have the external under-wing fuel tanks fitted to the C1 and C3. The C4 version has two 'plugs' inserted into the fuselage to extend it by some 15ft (4.58m) longer than the C5.
