U.S. Space Force Contracts

U.S. Space Force Contracting Overview

The United States Space Force (USSF), established in December 2019 as the sixth branch of the U.S. military, is responsible for organizing, training, and equipping forces to protect American and allied interests in space. As the primary military service for space operations, the Space Force manages a substantial portfolio of contracts spanning satellite development, launch services, ground systems, and space domain awareness.

Space Force contracting activity has grown significantly since the branch's founding, reflecting the increasing strategic importance of space-based capabilities for national defense. The service works closely with the Space Development Agency, Space Systems Command, and commercial partners to acquire and deploy next-generation space systems.

Space Systems Command

Space Systems Command (SSC), headquartered at Los Angeles Air Force Base, serves as the Space Force's acquisition arm. SSC is responsible for developing, acquiring, and sustaining space systems that provide critical capabilities to warfighters and the nation.

Core Mission Areas

SSC manages contracts across several key mission areas:

• Launch Services: Procuring assured access to space through the National Security Space Launch (NSSL) program
• Missile Warning and Tracking: Developing next-generation infrared sensing systems for early missile detection
• Satellite Communications: Acquiring protected and wideband communication satellites for military operations
• Space Domain Awareness: Building systems to detect, track, and characterize objects and threats in orbit
• Position, Navigation, and Timing: Sustaining and modernizing the GPS constellation

National Security Space Launch

The National Security Space Launch (NSSL) program is one of the Space Force's largest and most visible contracting efforts. NSSL ensures the U.S. government has reliable, cost-effective access to space for its most critical national security payloads.

NSSL Phase 2

Under NSSL Phase 2, the Space Force awarded launch service contracts to United Launch Alliance and SpaceX, covering the majority of national security missions from 2022 through 2027. These contracts guarantee access to a range of orbits, including geostationary, polar, and other high-energy trajectories required by defense and intelligence payloads.

NSSL Phase 3

NSSL Phase 3 introduces a two-lane acquisition strategy. Lane 1 covers missions with less demanding requirements and is open to a broader set of launch providers. Lane 2 addresses the most complex and heaviest national security payloads. This structure is designed to increase competition while maintaining assured access for the most critical missions.

SDA Proliferated Warfighter Space Architecture

The Space Development Agency (SDA), which transitioned into the Space Force in 2023, manages the Proliferated Warfighter Space Architecture (PWSA). This program represents a departure from traditional space acquisition, favoring large constellations of smaller, lower-cost satellites over small numbers of exquisite platforms.

Transport Layer

The Transport Layer provides a global mesh network of optically interconnected satellites in low Earth orbit. These satellites relay data with low latency between sensors, command nodes, and weapon systems across the battlespace. Contracts for Transport Layer satellites have been awarded to multiple vendors, including York Space Systems and Lockheed Martin, promoting competition and resilience.

Tracking Layer

The Tracking Layer deploys space-based sensors designed to detect and track advanced missile threats, including hypersonic glide vehicles. L3Harris Technologies, Northrop Grumman, and other contractors have secured Tracking Layer awards across multiple tranches, with each generation expanding the constellation's capability and coverage.

Program Tranches

• Tranche 0: Initial demonstration capability, with satellites launched in 2023-2024
• Tranche 1: First operational tranche, scaling to dozens of satellites per layer
• Tranche 2 and beyond: Expanded sensor diversity, deeper joint force integration, and enhanced resilience

Tactically Responsive Space

Tactically responsive space (TacRS) is a growing priority for the Space Force. The concept focuses on the ability to rapidly deploy or reconstitute space capabilities in response to emerging threats or operational needs. TacRS contracts emphasize speed, flexibility, and affordability.

Key elements of tactically responsive space include:

1. Rapid Launch: Contracts for launch vehicles capable of reaching orbit within days or hours of a launch order
2. Modular Spacecraft: Standardized satellite buses that can be quickly configured with mission-specific payloads
3. Streamlined Acquisition: Simplified procurement processes that reduce the timeline from contract award to on-orbit capability

Missile Warning and Missile Tracking

Missile warning remains one of the Space Force's highest-priority missions. The transition from the legacy Space-Based Infrared System (SBIRS) to the Next-Generation Overhead Persistent Infrared (Next-Gen OPIR) system is driving significant contract activity.

Lockheed Martin serves as the prime contractor for Next-Gen OPIR, building satellites with improved sensitivity and survivability for geosynchronous orbit. Northrop Grumman develops the polar-orbiting component. Together, these systems provide continuous global coverage for detecting ballistic missile launches and other infrared events.

The SDA's Tracking Layer complements these programs by adding a proliferated LEO layer optimized for tracking advanced threats that legacy systems may struggle to follow through their entire flight path.

Space Domain Awareness

As the orbital environment grows more congested and contested, the Space Force has increased investment in space domain awareness (SDA) capabilities. Contracts in this area cover ground-based sensors, space-based surveillance platforms, and data fusion systems that provide a comprehensive picture of the space environment.

Key contract areas include:

• Space Fence: A ground-based S-band radar system operated by the Space Force to detect and track objects in low Earth orbit
• Deep Space Advanced Radar Capability (DARC): Next-generation ground-based radar for tracking objects in geosynchronous orbit and beyond
• Commercial SDA Integration: Partnerships with commercial providers to supplement organic military tracking capabilities

Key Contractors

The Space Force works with a mix of established defense primes and emerging commercial space companies. Major contractors include:

• Lockheed Martin: Next-Gen OPIR, GPS III/IIIF, missile defense systems
• Northrop Grumman: PWSA satellites, Next-Gen OPIR polar, ground systems
• SpaceX: NSSL launches, Starshield, commercial broadband for military use
• United Launch Alliance: NSSL launches with Vulcan Centaur
• L3Harris Technologies: PWSA Tracking Layer, responsive space, payloads
• Raytheon (RTX): Space sensors, ground-based missile defense integration
• York Space Systems: SDA Transport Layer satellites
• Rocket Lab: Responsive launch and small satellite missions

Contract Trends

Several trends are shaping Space Force contracting:

1. Commercial-First Approach: Increasing preference for commercial solutions and commercial service contracts over traditional cost-plus development programs
2. Fixed-Price Contracts: Greater use of firm-fixed-price contracts to control costs and incentivize efficiency
3. Multi-Vendor Awards: Splitting programs across multiple contractors to promote competition and reduce single-point-of-failure risk
4. Small Business Participation: Growing opportunities for small businesses and non-traditional defense contractors, particularly in software, cybersecurity, and data analytics
5. Rapid Prototyping: Use of Other Transaction Authority (OTA) agreements and rapid prototyping contracts to accelerate innovation
