Statement of Work (SOW) for Long Duration Propulsive Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA)

(LDPE)

For Official Use Only (FOUO) Distribution C January 12, 2017

Scope This Statement of Work (SOW) defines the effort required by the Contractor for the Long Duration Propulsive ESPA (LDPE) Program. Unless otherwise specified, the Contractor shall provide all personnel, facilities, materials, and services necessary to meet the requirements of this SOW.

LDPE is intended to entail, and support, Mission Risk Class C and D missions; Class B payloads on LDPE would be the exceptions. However, LDPE is also intended to be co-manifested with Class A/B missions for launch, therefore “Do No Harm,” and supporting safety and risk processes shall assume satisfaction of both these standards and levels during all phases (see next section) of work.

LDPE extends Air Force Space Command’s (AFSPC) standard service policy for rideshare, leveraging previous propulsive ESPA development. LDPE will be controlled using Enterprise Ground Services as the baseline for command and control. The effort will include spacecraft payload integration services, and one year of early orbit checkout and operations. The nominal profile for LDPE missions is illustrated in Figures 1.1 and 1.2.

The term “ESPA” (EELV (Evolved Expendable Launch Vehicle) Secondary Payload Adapter) is used to describe a payload adapter class whose development was sponsored and demonstrated by the Air Force Research Laboratory (AFRL); it is not intended to indicate a specific article or vendor. Any equivalent, qualified, payload adapter technologies or structures may be used, but the ESPA is the government’s reference instance.

Figure 1.1 -- LDPE Launch to Orbit

Figure 1.2 -- LDPE On-Orbit Operations Phases There are three major phases of effort defined for the LDPE: Phase-1, LDPE Platform Assembly, Integration, and Test; Phase-2, Payload Integration & Test (I&T), and Launch Vehicle Integration Support & Launch Support; and Phase-3, Early Orbit Checkout and On-Orbit Support. The work in each of the three activities is not entirely serial; information or effort may be required from later phases for satisfactory completion of work in earlier phases. The complete effort also involves system-level management, engineering, and other associated support activities across all phases.

Table 1.1. Contract Structure

Phase-1 Description LDPE Assembly, Integration & Test (Phase-1) includes any design and development required for satisfaction of SOW requirements, followed by assembly, integration and test of the LDPE article, and culminates in a platform ready for payload/s integration at the system level.
