It's the biggest defense deal in years: Orbital Sciences and Alliant agree to a $4.5 billion merger. Alliant, known as ATK, will spin off its sporting goods group known for its rifles.

Whiteman believes many deals have been waiting to see some thawing from the government and this looks to be the first sign.
