Rocket Lab operates through two reporting segments that pair launch revenue with a larger spacecraft and components business. In 2025, Launch Services generated $199.0 million of revenue, while Space Systems generated $402.8 million. That made Space Systems the larger economic engine of the company. Backlog showed the same pattern. At December 31, 2025, total backlog stood at $1.85 billion, with $1.37 billion tied to Space Systems and $475.6 million tied to Launch Services. On March 18, 2026, Rocket Lab added a $190 million HASTE award, lifting total backlog to more than $2 billion and launch backlog to more than 70 missions.
- Launch Services
Launch Services covers dedicated and rideshare missions with Electron plus hypersonic test launches with HASTE. Electron remains the core product in small launch. Through December 31, 2025, Electron had completed 75 successful missions and deployed more than 200 spacecraft. Rocket Lab flew 21 missions in 2025 with a 100% mission success rate for the year, giving it one of the highest launch cadences in the sector. HASTE adds a defense-focused niche inside the same manufacturing and launch stack, and the new $190 million MACH-TB 2.0 contract shows that this part of the business is becoming more meaningful. Neutron is designed to extend Rocket Lab into medium-lift missions, with reusable low Earth orbit capacity of up to 13,000 kg. After a stage-1 tank test failure in January 2026, Rocket Lab moved Neutron’s first launch target to Q4 2026.
- Space Systems
Space Systems now sits at the center of Rocket Lab’s model. The segment includes spacecraft design and manufacturing, the Photon platform, mission software, mission operations, and a broad set of merchant components such as reaction wheels, star trackers, radios, separation systems, batteries, solar power solutions, and optical systems. Photon is important because it lets Rocket Lab sell more than hardware. It supports a fuller mission package that includes spacecraft manufacturing, ground services, and on-orbit operations. In 2025, Space Systems produced $402.8 million of revenue, including $371.6 million from products and $31.1 million from services. Rocket Lab says its flight hardware has now supported more than 1,800 missions.
Rocket Lab has also widened this segment through acquisitions and larger government programs. The GEOST acquisition in August 2025 added electro-optical and infrared payloads for missile warning, tracking, and space domain awareness. The Optical Support acquisition in February 2026 added precision optical and optomechanical systems that strengthen Rocket Lab’s payload and subsystem depth. That broader stack helped Rocket Lab win an $816 million Space Development Agency contract in December 2025 to design and build 18 satellites, a strong sign that the company is moving up the value chain in national security space.
Market position
Rocket Lab competes across three layers of the space market. In launch, its main competitors include Northrop Grumman, SpaceX, United Launch Alliance, Firefly, and Blue Origin, alongside other national launch providers. In spacecraft, it competes with larger primes such as Airbus, Lockheed Martin, Boeing, Maxar, Northrop Grumman, Thales Alenia Space, York Space Systems, and L3Harris. In components, competitors include Ball Aerospace, Raytheon, Collins Aerospace, Honeywell, Redwire, and Beyond Gravity. Rocket Lab’s edge is that it combines rockets, spacecraft, components, payloads, software, and mission operations inside one structure. That improves schedule control, customization, and supply chain visibility, which matters for constellation work and national security programs.
