A sea-based launch partnership moves toward construction
Kratos Defense & Security Solutions and Seagate Space have announced a long-term agreement centered on a mobile offshore launch platform intended for national-security missions. Kratos plans to use Seagate Space’s first Gateway platform for an initial mission in 2027, followed by multiple additional launches in subsequent years, according to the companies.
The agreement arrives alongside Seagate Space’s execution of its first Gateway platform construction contract. That step moves the proposal from a concept and development effort into physical construction, though the platform still must be completed and made operational before the planned missions can take place.
The companies are positioning the Gateway system as a modular, mobile maritime alternative that can complement fixed terrestrial launch sites and test ranges. Kratos initially expects to use it for defense-related launch and target missions, with the partnership aimed at a growing set of requirements that includes hypersonic testing, ballistic-missile targets and responsive launch capabilities.
Why mobility changes the launch equation
Land-based launch facilities and test ranges are fixed assets. Their location, airspace and range geometry can determine when and how a mission can be conducted. A platform that can operate at sea is intended to give planners another option: the ability to select operating locations and launch geometry that better fit a specific mission, while reducing dependence on terrestrial infrastructure.
Seagate Space says its Gateway vessels are designed as flexible, sea-based platforms for launch, testing and recovery work. The company describes the infrastructure as modular and mobile. In practice, that approach could support missions that need particular trajectories or test environments without requiring every activity to be tied to a permanent range.
The announced use case is not a conventional commercial satellite launch service. Kratos plans to begin with defense-related applications, where responsive scheduling, test-range access and mission geometry can be important constraints. The partners say their collaboration could expand as demand grows for national-security-relevant missions.
Kratos brings mission demand
Kratos has experience in systems and services relevant to the proposed work, including hypersonic test vehicles, rocket systems, propulsion technologies, target vehicles and launch services. Under the agreement, that experience is being paired with Seagate Space’s offshore platform infrastructure.
Dave Carter, president of Kratos Defense & Rocket Support Services, said the agreement creates an additional pathway for customers’ evolving launch and test needs. He described Gateway as a potential source of added launch flexibility, more operating locations and responsive access to mission-relevant test environments.
The distinction is important. The companies are not claiming that an offshore platform will replace every terrestrial range. They describe it as a complement to traditional sites. Fixed ranges retain their own capabilities, established procedures and infrastructure; the Gateway concept is meant to add another layer of capacity and flexibility where maritime operations offer an advantage.
Seagate Space puts its first platform into build
For Seagate Space, the first construction contract is a key operational milestone. The company says Gateway is being developed to support government and commercial launch, testing and recovery missions. The Kratos agreement supplies an identified early user and a planned first mission date, while construction provides a concrete route toward readiness.
Sean Fortener, Seagate Space’s president, chief operating officer and co-founder, said the company’s goal is to make access to space more open through maritime infrastructure. He characterized the partnership with Kratos and the start of construction as moving from vision toward physical implementation.
That framing captures both the opportunity and the remaining work. An agreement and a construction contract do not by themselves establish a functioning range or launch service. The platform will need to be built, integrated into operational processes and shown capable of supporting the intended missions. The companies have not detailed all technical, regulatory or operational steps in the announcement.
Hypersonic testing and responsive operations
The partnership is particularly relevant to testing and launch activities where geography matters. Hypersonic systems, ballistic-missile targets and other defense programs can require carefully selected routes and safety arrangements. A mobile offshore platform could allow operations to be placed where their geometry and range access are better suited to the mission.
It could also provide scheduling options when land-based ranges are busy or constrained. The companies explicitly cite reduced dependence on fixed terrestrial infrastructure as a potential benefit. That does not guarantee faster access in every case, but it identifies the capability the platform is designed to add.
For Kratos, the planned 2027 mission serves as the first practical test of the arrangement. For Seagate Space, it offers a route to demonstrate that its platform can support real defense requirements rather than only a prospective market. Multiple launches are anticipated after the first mission, subject to the platform’s progress and mission demand.
An additional layer of launch infrastructure
The broader significance of the announcement is the effort to turn offshore mobility into launch and test infrastructure. Rather than building only more fixed facilities, the partners are pursuing a vessel-based system intended to be repositioned according to mission needs.
Its value will ultimately depend on execution: the completion of Gateway, its operational readiness and the results of the planned missions. But with construction beginning and a 2027 Kratos mission on the calendar, the project has moved beyond a general aspiration. It is now a specific attempt to add mobile offshore capacity to the defense launch and test ecosystem.
