Lockheed Martin, the $47B defense contractor hit hard by the federal budget sequester, has filled the slot of a retiring communications exec and made an outside hire for another PR post.

The moves follow last month's hire of Bush White House and APCO alum Gordon Johndroe for Lockheed's top media relations slot. 

Jessica Nielsen, who led global communications for Dell's IT services business, has moved to Lockheed as VP of communications for its information systems and global solutions division, a unit hit by voluntary layoffs in March. The VP post had been vacant for several months, according to a company spokeswoman.

Lockheed, which is facing an $825M hit from the sequester and offered buyouts to employees earlier this year, also promoted Andrea Greenan to VP of comms. for its space systems business to replace the retiring 35-year vet Jan Wrather. Both report to VP, corporate comms., Jennifer Whitlow.

Based in Bethesda, Md., Nielsen oversees PR for a unit of the defense contractor with $9B in sales. The unit's  IT services and systems are used by NASA, the Defense Dept. and Dept. of Energy, to name a few, with applications as diverse as security, human resources and data gathering.

She was previously with BAE Systems (dir., media relations), CropLife America (external comms. lead), General Dynamics (sr. mgr., mktg. & PR), Oracle and Ruder Finn.

Lockheed had 2012 sales of $47.2B.  Marillyn Hewson took the reins as CEO in January.

Gordon Johndroe, a Bush White House PR staffer, joined Lockheed as VP of media relations and international communications last month from APCO Worldwide.
