BOCA RATON, Florida. Terran Orbital delivered 42 satellite bus platforms to Lockheed Martin in support of the Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture Tranche 1 Transport Layer, the company announced in a statement.

The Tranche 1 Transport Layer is intended to enhance connectivity for warfighters by establishing a resilient satellite communications architecture, the company says.
