L3Harris Technologies is nearing a deal to sell a majority stake in its space propulsion business to private equity firm AE Industrial Partners, according to sources familiar with the matter. The transaction, which could value the unit at more than USD 500 million, marks another significant step in the reshaping of the U.S. aerospace and defence industrial base.
The assets under consideration are understood to include Aerojet Rocketdyne’s electric propulsion and related space systems, which L3Harris acquired as part of its USD 4.7 billion purchase of Aerojet Rocketdyne in 2023. While L3Harris will reportedly retain a minority stake, operational control is expected to pass to AE Industrial.
Strategic realignment after Aerojet acquisition
L3Harris’ acquisition of Aerojet Rocketdyne was driven primarily by the need to secure solid rocket motors and hypersonic propulsion capabilities for U.S. and allied defence programmes. However, not all of Aerojet’s portfolio aligned with L3Harris’ long-term strategic focus.
By divesting parts of the space propulsion business, L3Harris appears to be sharpening its focus on core defence priorities, including missile systems, classified space payloads, electronic warfare and integrated mission solutions. The move also reflects broader industry trends, as large defence primes streamline portfolios while private equity firms expand their footprint in specialised space and propulsion niches.
AE Industrial strengthens space and propulsion portfolio
For AE Industrial Partners, the transaction would further deepen its exposure to high-growth aerospace and space technologies. The firm has built a strong presence across aviation services, defence manufacturing and space-related assets, often targeting businesses with stable government demand and advanced engineering capabilities.
Electric propulsion systems, in particular, are becoming increasingly critical for satellite constellation operators, defence space architectures and deep-space missions, driven by demand for greater efficiency, manoeuvrability and extended mission lifetimes.
Implications for the space and defence market
If completed, the deal would underscore a continuing rebalancing of the space sector, where traditional defence primes increasingly coexist with private equity-backed specialists and new-space entrants. It also highlights the enduring strategic value of propulsion technologies amid rising geopolitical tensions and expanding military use of space.
Neither L3Harris nor AE Industrial has officially commented on the potential transaction. The deal is not yet final and remains subject to regulatory approvals and customary closing conditions.
