HUNTSVILLE, AL—Aerojet Rocketdyne, which makes rocket engines and motors for the aerospace and defense industry, will build a 379,000-square foot assembly plant here.

The factory will “allow Aerojet Rocketdyne to increase manufacturing capacity for the nation’s defense production needs,” the company said in a press release. It will take some work from the company’s Camden, AR, factory, but the amount was not specified. The move “better positions the Camden site to support continued growth of vital energetics capabilities for defense programs across multiple domains,” the company said.

“Huntsville has been home to Aerojet Rocketdyne’s defense headquarters since its founding, and with this expansion of both talent and space, we’re pleased to grow our presence in the Rocket City,” says Eileen P. Drake, CEO and president of Aerojet Rocketdyne.

The company did not say how many new jobs it plans to fill in Huntsville, and a spokesperson was not immediately available. It has more than 800 employees in the city now.
