Aerojet says government asking it to invest too much in its own engine

Rocket company seeks to reduce its share of costs from one-third to one-sixth.

The propulsion company Aerojet Rocketdyne, formed in 2013 by two of America's most storied rocket engine manufacturers, has been working a new engine, known as the AR1, since 2014. Almost from its outset, however, the AR1 has faced two primary questions: who would pay for its development, and who would use the new engine.

In recent years, Aerojet has sought funding from the US Air Force to design and build the AR1, which has approximately 20 percent more thrust than a space shuttle main engine. The Air Force, in turn, has pledged as much as $536 million in development costs provided that Aerojet puts its own skin in the game—about one-third of research and development expenses.

According to a new report in Space News, Aerojet is now saying that even this modest investment is too much, and the company is seeking to reduce its share of the development costs from one-third to one-sixth. “As we look to the next phase of this contract, we are working with the Air Force on a smart and equitable cost-share,” Aerojet spokesman Steve Warren told the publication. “We are committed to delivering an engine in 2019.”
