/**
 * Thrust of a nozzle, the way Futurism's vectored afterburner makes it: the power comes from the Warium jet exhaust
 * directly behind the nozzle, which hands it over through its {@code ExhaustPower} value instead of pushing the ship
 * itself because the nozzle is in the {@code warium_vs:blocksjet} tag. The push goes opposite to the way the exhaust
 * leaves, so a nozzle deflected upwards pushes the tail down. Only used where Warium VS is installed.
