Rocket Systems Launch Program

The Rocket Systems Launch Program (RSLP) is a procurement initiative managed by the United States Space Force, under the Air Force budget, focused on acquiring small launch services to meet the needs of national security and government space missions. The primary goal of RSLP is to provide affordable and flexible spacelift options for small payloads, which are essential for supporting a wide range of developmental, demonstration, and operational space vehicles. By offering dedicated spacelift and rideshare services, the program ensures that various agencies can deploy small satellites and other payloads efficiently and responsively.

RSLP is designed to complement the larger National Security Space Launch (NSSL) program by addressing requirements unique to small spacecraft and payloads. While NSSL focuses on heavy and medium-lift launches for major national security missions, RSLP fills the gap for missions that require smaller, more agile launch solutions. This dual approach allows the Department of Defense and its partners to maintain a robust and resilient launch capability, tailored to the diverse needs of modern space operations.

The objectives of RSLP include the procurement of launch services rather than the acquisition of hardware or weapon systems. The program does not take ownership of any specific launch vehicle; instead, it contracts with commercial providers to deliver launch capacity based on Government National Launch Forecast requirements. This approach leverages the commercial space industry's innovation and flexibility, enabling the government to access a variety of launch vehicles and services without the burden of maintaining its own fleet.

RSLP supports missions for multiple government agencies, with funding for each mission provided by the respective partner on a reimbursable basis. In addition to direct procurement under the Space Force's budget, RSLP is supported by related program elements such as APPN 3620, RDT&E, Space Force, and PE 1206860SF. The program continues to execute previously funded missions and remains available to support new requirements as they arise. No new procurement funds are requested for FY 2026 or beyond.

One of the key justifications for RSLP is its alignment with the Spacelift Capability Production Document approved on May 31, 2016. This document established the need for a dedicated small spacelift capability within the Department of Defense. The requirement is driven by increasing demand for rapid, cost-effective access to space for small satellites and experimental payloads, which are critical for technology development, operational demonstrations, and responsive national security missions.

RSLP does not include advance procurement or initial spares, and the concept of flyaway unit cost is not applicable due to the mix of launch vehicles utilized. The program's structure is designed to maximize flexibility and cost-effectiveness, allowing the government to adapt to evolving mission requirements and technological advancements in the commercial launch sector.
