No, not quite. Cargo cults didn’t worship the vehicles, rather the notion of the abundance that they brought. The famous Melanesian ones in WWII happened in societies in which gift-giving was already the key to social power; when WWII came along, both the Japanese and Allied forces brought unbelievable quantities of supplies to the islands and then also intentionally handed out a lot of stuff in order to play into that social practice. It was enough that some locals interpreted it as a sign that they could return to their old ways that had been suppressed under Christian colonial rule, the first signs of a coming new age of prosperity

Anyway all that is to say that no, uncontacted tribes can’t have cargo cults because part of the formation of a cargo cult involves contact
