The Committee on Armed Services , sometimes abbreviated SASC for Senate Armed Services Committee , is a committee of the United States Senate  empowered with legislative oversight  of the nation's military , including the Department of Defense , military research and development , nuclear energy  (as pertaining to national security ), benefits for members of the military, the Selective Service System , and other matters related to defense policy.[ 1]   The Armed Services Committee was created as a result of the Legislative Reorganization Act of 1946  following the U.S. victory in World War II . The bill merged the responsibilities of the Committee on Naval Affairs , established in 1816, and the Committee on Military Affairs , also established in 1816.[ 1]  
Considered one of the most powerful Senate committees, its broad mandate allowed it to report some of the most extensive and revolutionary legislation during the Cold War  years, including the National Security Act of 1947 .  The committee tends to take a more bipartisan approach than other committees, as many of its members formerly served in the military or have major defense interests located in the states they represent.[ 2]   The committee's regular legislative product is the National Defense Authorization Act  (NDAA), which has been passed by Congress  and signed into law annually since 1962.[ 3]  
The current chair is Republican Roger Wicker  of Mississippi, and the ranking member is Democrat Jack Reed  of Rhode Island.

^   At the beginning of the 107th Congress in January 2001 the Senate was evenly divided. With a Democratic president and vice president still serving until January 20, the Democratic vice president was available to break a tie, and the Democrats thus controlled the Senate for 17 days, from January 3 to January 20. On January 3 the Senate adopted S. Res. 7 designating Democratic senators as committee chairs to serve during this period and Republican chairs to serve effective at noon on January 20, 2001. 
 
^   On June 6, 2001, the Democrats took control of the Senate after Senator James Jeffords (VT) changed from the
Republican Party to Independent and announced that he would caucus with the Democrats.
