Rocketdyne to reappear with sale by L3Harris of its civilian rocket engine division
The name Rocketdyne is about to rise from the ashes with the sale by L3Harris of its civilian rocket engine division to the private equity firm AE Industrial Partners.
The firm is selling a 60 percent stake, worth $845 million, and maintaining about a 40 percent share of the space propulsion business unit, which focuses on technologies related to NASA and civil space activities. For example, its products include nuclear power systems for future missions to the moon and Mars, and the RL10 engine that powers the upper stage for United Launch Alliance’s Vulcan heavy lifter.
That said, the RS-25 rocket engine business is excluded from the sale; the engine is the primary propulsion system on NASA’s Space Launch System being designed to send crews to the moon under the Artemis mission.
When L3Harris purchased Aerojet-Rocketdyne in 2023, the names of these two companies from the very beginnings of the space age vanished. It now appears that AE is going to bring one back.
AE Industrial ― which previously has invested in commercial space companies including York Space Systems, Redwire and Firefly — said in an announcement today that the new entity will be named Rocketdyne “in recognition of its heritage and longstanding innovation within space propulsion technology.”
Aerojet-Rocketdyne had been in trouble for years prior to is purchase, and it remains uncertain whether the engine part of this new Rocketdyne company can compete. Its main business right now is building the engines used by the SLS rocket, which in the long run has a limited future.
