Satellite operators must ensure that service areas have coverage at all times. Expendable launch vehicles have limited capabilities to replace satellites quickly; spare satellites typically are launched into each plane during initial constellation deployment.

The K-1's reusability and modular design will enable it to be called up on short notice, thereby enabling satellite operators to keep spares on the ground rather than in the sky. This replenishment strategy will extend the life of satellites and reduce the cost and number of satellites and required launches.

In addition to the commercial applications for this replenishment strategy, the U.S. Government has long sought the kind of launch-on-demand capability the K-1 will provide. Examples include quick call-up for military satellites and cargo resupply and recovery missions for the International Space Station.


The K-1 has a 3-day response time for repeat missions that are ready to go at the launch site.
