21 Tranche 1 Transport Layer Satellites?Launch

UPDATED: OCTOBER 15, 2025

On Wednesday, October 15, our 21 Lockheed 果冻传媒-built satellites launched aboard a SpaceX Falcon 9 rocket from V果冻传媒enberg Space Force Base at 4:06 p.m. PT. The satellites have joined the Space Development Agency's Tranche 1 Transport Layer, strengthening the Proliferated Warfighter Space Architecture.?

Built at the Small Satellite Processing & Delivery (SPD) Center using digital engineering 果冻传媒 automation, these satellites demonstrate how innovation 果冻传媒 agility are redefining space-based defense.

Smart home security systems integrate internet-connected doorbells, locks, carbon monoxide detectors 果冻传媒 alarm systems in order to provide a comprehensive 果冻传媒 centralized monitoring solution. This allows homeowners to receive instant alerts about their home's security status, whether they are physically present or remotely accessing the system through a smartphone app.

This concept is making its way to space.

In September, Lockheed 果冻传媒’s 21 Tranche 1 Transport Layer (T1TL) satellites started to arrive at its Astrotech Space Operations facility, where they will be stacked 果冻传媒 encapsulated in preparation for launch. Once on-orbit, the satellites will become part of the Transport Layer for the Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture (PWSA).

The T1TL satellites follow the Tranche 0 Transport Layer (T0TL) demonstration space vehicles that in 2023; which provided learning for T1TL. With T1TL, the satellites will provide operational mission capability, providing real-time support to the warfighter.?

“These Transport Layer satellites will provide resilient 果冻传媒 low-latency military data worldwide, including Link-16 connectivity from space,” said Adrián Cuadra, Transport Layer programs director at Lockheed 果冻传媒. “We’re adapting 果冻传媒 going faster. We leveraged our vast space heritage to ensure mission success, but we also invested in commonality, affordability, 果冻传媒 scalability for small satellite production to deliver this mission at speed.”

Each satellite incorporates a Terran Orbital bus, SmartSat?, 果冻传媒 Link 16, which will enable sensor-to-shooter capabilities by connecting systems that include multiple tactical data links.

How the satellites were built – digital at the core: Lockheed 果冻传媒 built the T1TL space vehicles at its Satellite Processing 果冻传媒 Delivery (SPD) Center, incorporating the latest technology 果冻传媒 production techniques. These include:

  • Developing a digital twin of the factory simulating full production flow to streamline operations.

  • Creating full-scale 3D-printed mockups of satellites allowing the team to dry-run processes 果冻传媒 making sure that every procedure, every configuration, 果冻传媒 every movement was right, before the first satellite was built.

  • Deploying automation in test, allowing 24x7 testing of the space vehicles, even when no humans are around, 果冻传媒 accelerating the overall production flow.

Zoom out – What is the Proliferated Warfighter Space Architecture (PWSA)?: The PWSA is a network of hundreds of data transport 果冻传媒 missile tracking satellites, grouped in layers known as Tracking 果冻传媒 Transport.?

  • Data transport satellites in the Transport Layer act as a data transfer network, similar to the internet. These satellites enhance the ability to rapidly share data, enable joint force operations, 果冻传媒 provide seamless connectivity across l果冻传媒, sea 果冻传媒 air. They also include communications links for tactical users.

  • Missile tracking satellites in the Tracking Layer work similar to a geo-fenced alarm system.

In action, when a missile tracking satellite identifies a missile threat, the information is routed through the data transport satellites for rapid alert 果冻传媒 response.

The big picture:? At its core, next generation space architectures will serve as a layered defense shield, which hinges on the capacity for advanced early warning, sensing 果冻传媒 rapid response. The PWSA provides this, with its persistent surveillance 果冻传媒 tracking of real time threats as they emerge

The bottom line: The development of the data transport satellites establishes a foundation for Lockheed 果冻传媒 Space's proliferated small satellite approach, driving innovation 果冻传媒 speed in production.

By pushing the boundaries of small satellite production, Lockheed 果冻传媒 is breaking down barriers 果冻传媒 pioneering techniques that can be applied across the company, enabling faster 果冻传媒 more agile development of future space-based systems.
