The Navy today commemorated its 2,000th Tomahawk cruise missile combat launch during a ceremony at Naval Station Norfolk aboard the destroyer Barry, which took part in the March air strikes on Libyan military facilities in support of U.N. Resolution 1973 and was credited with the 2,000th launch. Check this great pic of a launch from Barry the night the milestone was reached:

This was one of approximately 110 cruise missiles fired from U.S. and British ships and submarines that targeted about 20 radar and anti-aircraft sites along Libya's Mediterranean coast. // U.S. Navy photo by Interior Communications Electrician Fireman Roderick Eubanks
We don’t know if that is THE 2,000th or not, but you get the idea. Even better: Check the video.
The commemoration honored the Barry crew members for their role in the milestone launch.
Tomahawks have been around for more than 30 years and have been used in every major U.S. combat operation since the first Gulf War in 1991. It can be launched from Navy ships and submarines, as well as Air Force bombers. It’s also used by the Royal Navy.
