Washington, D.C. has a new air defense system stationed at the Naval Surface Warfare Center:

The launcher claims a commanding position on the lawn at the U.S. Naval Surface Warfare Center’s Carderock facility, a science and engineering center overlooking the Potomac River, the WASHINGTON POST will report on Tuesday.

The six non-nuclear missiles in the launcher could “counter an inbound threat.”

If you are interested in how missile guidance systems work, listen to this explanation from an actual training tape. You have to listen to the whole thing, but it’s only about 90 seconds long.

And yes, folks, it actually makes sense!
