The Department of Defense awarded five defense contracts Friday, worth a total of $719.3 million.

The vast amount of the day's awards went to privately held defense contractors. These included the day's biggest contract -- a $497 million IDIQ contract requisitioning technical support in the development and integration of command, control, communications, computers, intelligence, surveillance, and reconnaissance for the U.S. Army, and also its second largest -- a $157.5 million award for the procurement of unspecified "commercial type environmental equipment." Among publicly traded corporations, though, only one received work from the Pentagon today: Snap-On (NYSE:SNA).

The tools and diagnostic equipment maker won a $37.7 million firm-fixed-price, indefinite-delivery/indefinite-quantity contract to supply the U.S. Army with aviation tool kits for use in maintenance work on its helicopters. This contract will run through Feb. 12, 2019.
