The launch provider solidifies its pivot to space systems with an $816 million award to build 18 missile-tracking satellites for the U.S. Space Force's Space Development Agency.
WASHINGTON, D.C. - In a significant expansion of the United States' orbital defense capabilities, the Space Development Agency (SDA) has awarded approximately $3.5 billion in contracts to four aerospace companies to construct the next generation of missile-tracking satellites. Among the recipients is Rocket Lab USA, Inc., which has secured a prime contract worth up to $816 million to design and manufacture 18 satellites for the Tranche 3 Tracking Layer.
The announcement, made late this week, marks a definitive milestone for Rocket Lab, a company once known almost exclusively for its Electron launch vehicle. By securing a seat at the table alongside defense heavyweights Lockheed Martin and L3Harris, Rocket Lab has effectively cemented its transition from a niche launch provider to a major prime contractor for complex space systems. The deal is part of the Pentagon's aggressive push to build the Proliferated Warfighter Space Architecture (PWSA), a mesh network of hundreds of satellites designed to detect and track hypersonic missile threats.

According to reports from DefenseScoop and SpaceNews, the SDA's latest funding tranche is divided among four key players, each tasked with delivering 18 satellites, totaling 72 new spacecraft for the constellation. The awards break down as follows:
This award follows a trajectory of rapid growth for Rocket Lab's space systems division. In January 2024, the company received a $515 million prototype agreement for the SDA's Tranche 2 Transport Layer. With this new Tranche 3 award, Rocket Lab's total contract value from the SDA now exceeds $1.3 billion, underscoring the Pentagon's increasing reliance on "non-traditional" defense contractors to accelerate innovation.
The distinction between Rocket Lab's previous win and this current contract is significant from a technological standpoint. The earlier Tranche 2 award focused on the "Transport Layer"-essentially the optical communication backbone of the network, designed to move data rapidly around the globe.
The new Tranche 3 contract involves the "Tracking Layer." These satellites are equipped with advanced infrared sensors specifically calibrated for "Missile Warning, Tracking, and Defense" (MWTD). As noted by GovCon Wire in earlier analyses of the program, these spacecraft are critical for detecting ballistic and hypersonic missiles from launch through their flight trajectory. The integration of fire-control quality sensors means these satellites don't just see the threat; they provide the precise data needed for interceptors to neutralize it.

The SDA's strategy, often championed by Director Derek Tournear, relies on "proliferation"-launching hundreds of smaller, cheaper satellites rather than a few massive, expensive "battlestar" satellites. This approach requires a diversified industrial base capable of high-rate production. By selecting Rocket Lab and Sierra Space alongside traditional giants like Lockheed Martin, the government is actively nurturing a competitive ecosystem to drive down costs and speed up deployment.
Experts point to Rocket Lab's vertical integration as a key factor in its success. Unlike competitors who may rely heavily on complex supply chains, Rocket Lab manufactures many of its own components, from reaction wheels to solar panels. This internal control is increasingly attractive to defense planners worried about supply chain fragility. Air & Space Forces Magazine highlighted this expansion of focus "from launch to satellite production" as a critical evolution for the firm.
With the contracts now signed, the focus shifts to execution. The timeline for the SDA's architecture is aggressive. While Tranche 2 satellites are slated for launch no later than 2027, the Tranche 3 constellation will follow closely behind, aiming to operationalize a persistent global missile defense shield before the end of the decade.
For Rocket Lab, the immediate challenge will be scaling production facilities to meet the dual demands of the Transport and Tracking layer contracts simultaneously. Successfully delivering these 36 satellites (18 Transport + 18 Tracking) on schedule would likely solidify its position as a primary pillar of U.S. national security space infrastructure for years to come.
