Rocket Lab said 8 of the 18 spacecraft it is building for the Space Development Agency are now in production, in an update on progress under a $515 million contract. Stocktwits quoted the company as saying: "There are 8 of 18 spacecraft on the factory floor now, under construction." The figure indicates that active manufacturing covers part of the program’s fleet, while 10 of the 18 spacecraft under the contract remain outside this stage, based on the reported numbers. The update marks a shift into satellite construction, after the contract was announced in 2023. The progress is an execution milestone in a defense program of significant value to the company, while the project’s scheduled launch date of July 2027 remains ahead.

The agreement is valued at $515 million in total, comprising a base amount of $489 million and $26 million in incentives and options, according to Rocket Lab’s annual filing with the U.S. Securities and Exchange Commission. The breakdown shows that the full contract value does not come from the base amount alone, as the remainder is tied to incentives and options included in the agreement. The contract covers the construction of 18 spacecraft for the Space Development Agency, according to the production update reported by Stocktwits. The program thus combines a defined manufacturing scope with a contract value that includes a base component and another tied to incentives and options. This financial structure puts production progress in the context of the agreement announced in 2023, rather than as a new value announced by the company in the October update.

The satellites are part of the Tranche 2 program and will be integrated into the Space Development Agency’s Transport Layer, according to the company’s filing. Rocket Lab said the layer is intended to provide reliable, resilient, low-latency military data and connectivity on a global scale. This mission links the current manufacturing work to the services the satellites were designed to provide once integrated into the system. The company’s filing describes the connectivity as low latency, making data transmission speed part of the mission’s specifications alongside resilience and global reach. This gives the program an operational dimension beyond supplying spacecraft, placing them within a broader military communications architecture.

Rocket Lab says the 18 satellites will include subsystems and components manufactured in-house. These include solar panels, structures, star trackers and reaction wheels, as well as radios, flight software, avionics and the launch dispenser. The satellites are to be built at the company’s spacecraft development and manufacturing complex in Long Beach. In-house production brings a broad range of components into Rocket Lab’s facilities, from power and structural elements to control and communications systems and software. The approach also links spacecraft manufacturing with the assembly of the subsystems needed for their mission in the Transport Layer.

In trading, Rocket Lab shares rose 8% on Tuesday, October 27, to $58.31, marking a third consecutive session of gains, according to Stocktwits. The closing price matches EL7 data for the stock on the same date, which recorded a close of $58.31. Stocktwits also said the shares were up more than 1% in overnight trading ahead of Wednesday. The source reports the overnight move separately from Tuesday’s session gains, without specifying that it came directly after the production update. These figures provide a picture of the stock’s performance during the session and overnight trading, while the available data do not include confirmed session highs or lows.

The program’s scheduled launch date of July 2027 remains the next milestone on the announced timeline, according to information related to the project. The date follows the October 27 update that said 8 spacecraft had entered production, out of 18 in total. The timeline connects the current construction phase with satellite integration into the Transport Layer to provide the military connectivity and data services described by the company. The announced manufacturing plan relies on components and subsystems made in-house by Rocket Lab, with the satellites built at the company’s Long Beach complex. Upon launch, the spacecraft are expected to support the Space Development Agency’s Tranche 2 program.
