OSP-4 is a follow-on to the OSP-3 contract that is set to expire in November. OSP-4 will allow for the rapid acquisition of launch services to meet mission requirements enabling launch within 12-24 months from task order award on a competitive basis. It is designed to accommodate payloads greater than 400 lbs. The Air Force projects to procure about 20 missions over the nine year period.
This is a big deal for the Air Force, with a lot of missions up for grabs for launch vehicles that can send 180 kilograms or more to orbit. It’s not the huge payloads like NSSL flies, but 20 missions for the most vibrant sector of the launch market is just as interesting to me.
