As for the $515 million that is covered by this contract, fully $509 million goes to building and getting the satellites ready for launch by 2027, plus "schedule-driven profit incentives." (In other words, if Rocket Lab beats its deadline, it may earn a bit more cash.) As for the remaining $6 million, Rocket Lab revealed in its conference call this week that this amount may be earned if Space Force exercises an option to have Rocket Lab support its satellites beyond the initial 2027 to 2030 period and into 2033.
