Sierra Space, Lockheed Martin, L3Harris Secure $2.5B SDA Contracts for Missile-Tracking Satellites

The three firms will construct 54 satellites for the Proliferated Warfighter Space Architecture, marking Sierra Space's first major military satellite contract.

Sierra Space, Lockheed Martin, and L3Harris have been awarded contracts by the Space Development Agency (SDA) to build 54 satellites for the Proliferated Warfighter Space Architecture, a network of low-Earth orbit satellites providing missile warning, tracking, and defense capabilities.
Each firm will construct 18 satellites for the Tranche 2 (T2) Tracking Layer, with 48 satellites equipped with a wide field-of-view infrared sensor for missile warning and tracking, and six satellites with fire control-quality infrared sensors for missile defense.
The contracts are collectively worth $2.5 billion, with L3Harris receiving $919 million, Lockheed Martin $890 million, and Sierra Space $740 million.
This marks Sierra Space's first major contract with the SDA and its first significant deal to build satellites for the U.S. military.
The satellites are expected to be launched no later than April 2027.
