L3Harris Applied sciences has efficiently accomplished the essential design overview (CDR) and manufacturing readiness overview for the US House Pressure’s House Improvement Company’s (SDA) Tranche 2 Monitoring Layer.
This development to the manufacturing part signifies a big development within the improvement of a brand new, layered missile defence system able to real-time menace monitoring.
The CDR confirmed that L3Harris’ designs for each the house car and floor system are aligned with mission necessities.
These designs incorporate superior expertise able to globally detecting, monitoring, and focusing on missile threats with minimal delay.
L3Harris’ services have already commenced the manufacturing of main assemblies for the T2 house autos, demonstrating the corporate’s dedication to assembly SDA’s speedy deployment targets.
The designs leverage the corporate’s expertise from Tranche 1, Tranche 0, and the Missile Protection Company’s Hypersonic and Ballistic Monitoring House Sensor (HBTSS) satellites.
The corporate helps SDA’s Monitoring Layer throughout all tranches of the Proliferated Warfighter House Structure (PWSA), which envisions a complete constellation of satellites in low Earth orbit to boost missile warning, monitoring, and defence capabilities on a near-global scale.
Moreover, L3Harris is establishing eight electro-optical infrared (EO/IR) payloads for SDA’s Fireplace-control On Orbit-support-to-the-war Fighter (FOO Fighter) programme.
The corporate has been investing “lots of of tens of millions of {dollars}” in the direction of infrastructure and manufacturing processes throughout the US, together with a $250m initiative to improve and broaden services devoted to space-based missile warning and defence applied sciences in Indiana, Florida, and Massachusetts.
Earlier in 2025, Rocket Lab Nationwide Safety additionally completed the preliminary design review (PDR) for SDA’s Tranche 2 Transport Layer (T2TL)-Beta programme.
The Monitoring Layer goals to deploy a worldwide community of satellites outfitted with infrared sensors for missile warning and monitoring.
These satellites can be built-in with the Transport Layer’s high-speed communication community, facilitating superior missile monitoring from quite a few low-Earth orbit positions.
Upon full deployment, the T2 constellation is anticipated to embody round 270 operational satellites throughout each the Transport and Monitoring Layers, mentioned SDA.
