Orbital Sciences awarded contract for EELV secondary payload adapter

The Space Systems Division of the Orbital Sciences Corp. (Orbital ATK) has been awarded a contract for long duration propulsive evolved expendable launch vehicle (EELV) secondary payload adapter.

The value of the firm-fixed-price and cost reimbursement contract is around $34 million. The contract was awarded by Space and Missile Systems Center located at Kirtland Air Force Base, New Mexico.

The contract also extends Air Force Space Command’s (AFSPC) standard service policy for rideshare, leveraging previous propulsive EELV secondary payload adapter development.

The contract work will be performed at Dulles, Virginia, and is expected to be completed by July 1, 2019.

EELV Secondary Payload Adapter (ESPA) is a payload adapter ring for launching secondary payloads on EELV-class orbital launch vehicles.

The ESPA ring had been used on all 3 EELV rockets (Atlas V, Delta IV and Falcon 9). Multiple ESPA rings may be used on a single launch, stacked to increase the satellite carrying capacity.
