"These decisions are always difficult to make but necessary to protect the company's competitiveness and future," Jackson said.
Sikorsky is feeling the impact of reduced military spending due to budget cuts and a scaled-back U.S. presence in Afghanistan. Last month, Chief Financial Officer Greg Hayes said sales of the Black Hawk had fallen about 20 percent year over year.
Revenue and profit at Sikorsky have fallen in each of the last two years. Revenue in 2013 was $6.25 billion, down 8 percent from 2012 and off by 15 percent from 2011. Profit last year was $594 million, down 17 percent from 2012 and 29 percent lower than in 2011.
The company has about 8,200 employees in Connecticut and 16,500 around the world.
Jackson said the cuts will be split between salaried and hourly positions. He said transition assistance will be provided to employees who lose jobs.
