L3Harris secures $150 million Space Force contract for ground system modernisation

L3Harris has received a $150 million contract from the US Space Force's Space Systems Command under the MOSSAIC programme to sustain and modernise ground systems for space situational awareness. The contract supports faster decision-making, earlier threat warning, and sustained space superiority in a contested domain.

L3Harris Technologies has received a $150 million contract from the US Space Force's Space Systems Command to sustain and modernise critical ground systems under the Maintenance of Space Situational Awareness Integrated Capabilities (MOSSAIC) programme, according to an official announcement. The contract supports faster decision-making, earlier threat warning, and sustained space superiority.

L3Harris is a defence and aerospace technology company providing space domain awareness technologies and mission-critical services. The MOSSAIC programme is entering its seventh year of a decade-long effort to deliver reliable, high-availability surveillance data to military, civil, and commercial stakeholders. The contract ensures commanders have timely, accurate insight to protect critical space assets and maintain freedom of action in space.

This development matters for the space defence sector, where ground systems are critical infrastructure for space situational awareness. The ability to detect threats earlier and respond faster is increasingly important as the space domain becomes more contested with anti-satellite weapons and orbital congestion.

For the defence industry, the contract reinforces L3Harris's position as a provider of ground systems for space surveillance. Stakeholders including military space operators, civil space agencies, and commercial satellite operators stand to benefit from improved space domain awareness data. The company has provided space domain awareness technologies and mission-critical services in support of national defence for more than 30 years.
