Gulfstream Aerospace Corp. announced plans Monday to hire at least 50 new employees as the firm expands its repair and maintenance operations in Long Beach.

The luxury jet manufacturer plans to add a new hangar and office space to Gulfstream Long Beach, where the company has roughly 900 employees.

Gulfstream Long Beach general manager Becky Johnson said in a statement the expansion is expected to be complete some time in mid- to late-summer.

The company’s announcement is the latest news indicating aerospace continues to have a presence in Long Beach, although the days of producing large military aircraft and jumbo jets in the city will soon come to a close. Boeing Co. is winding down its production of the C-17 Globemaster III military transport jet this year, but like Gulfstream, Virgin Galactic is another firm finding reasons to invest in Long Beach.

Virgin Galactic in February announced plans to build satellite launch vehicles at a Long Beach plant.

Gulfstream’s planned 19,000-square-foot hangar will be able to accommodate three large-cabin Gulfstream jets, the company reported.

Gulfstream presently operates a completion center for its GF 550 and GF 650 jets, as well as a service center and sales and design center in Long Beach. Technicians working at its facility near Long Beach Airport serviced more than 1,000 aircraft there in 2014.

A Gulfstream spokesman said job descriptions will be posted online at www.gulfstream.com/careers. The company notes on its website that new jobs are posted on Thursdays and applications must be submitted online.
