Boeing Co said on Wednesday its quarterly profit increased more than expected, driven by growth in defense programs.

The world's No. 2 planemaker said second-quarter net profit rose to $998 million, or $1.41 per share, from $852 million, or $1.16, a year earlier. Analysts expected profit of $1.21 per share, according to Reuters Estimates.

Its 2009 earnings forecast was unchanged between $4.70 and $5 per share.

Total revenue increased 1 percent to $17.15 billion. Revenue from its commercial airplane division decreased 2 percent to $8.4 billion on lower deliveries. Revenue from the integrated defense systems unit rose 9 percent to $8.7 billion. Revenue from Boeing Capital increased 7 percent to $167 million.

The commercial unit booked 57 gross orders during the quarter, while 52 others were removed from its order book.

Boeing said its backlog was $328 billion, down 3 percent from a year ago.

Chicago-based Boeing and rival Airbus are being hit hard as carriers and cargo operators grapple with a recession in many parts of the world.
