On Monday, Lockheed Martin informed employees across its Mission Systems and Training, which employs 18,000, that there will be an involuntary layoff that will affect 300 U.S. positions.

Keith Little, senior manager of public relations at Lockheed's Mission Systems and Training, said the details of the layoff have not been determined yet, but that the number will be 300 across Mission Systems and Training, which Lockheed Martin in Owego, N.Y. is a part of.

Little also noted that it is unclear at this point how many will be affected at the Owego facility.

Little added, "Reducing our workforce is not a decision we make lightly. This reduction is necessary to address current business realities, including uncertain program funding, a delay in contract announcements and an extremely competitive market."

Lockheed Martin has 2,700 employees at its Owego facility, which handles Electronic Systems, Mission Systems and Sensors, and Ship and Aviation Systems. Lockheed's Mission Systems and Training employs a total of approximately 18,000 people in the U.S. and nine other countries.

Mission Systems and Training had $7.5 billion in 2012 sales, which includes naval systems, platform integration, simulation and training, and energy programs, according to Lockheed Martin's website.
