Here is an S-70B Seahawk walkaround from Avalon in 2007. The RAN operates 16 Seahawks with the first deliveries coming in 1988. The spec of these machines is unique, as often happens with military equipment for Australian conditions. The RAN birds have a sophisticated target tracking radar and electronics (That’s the round bit under the chin), as well as different data transfer and electronics suites. This airframe appears to have been renumbered from N24-002 to N24-015. from ADF Serials: Noted with serial numbers overpainted. The aircraft went in for repainting as a part of regular maintenance, the paperwork was mixed with another and it came out of the shop painted as N24-002 '71'. The mistake was corrected but still obvious.
