A Boeing Delta 4 Medium+ rocket will launch NRO L-22, a classified spy satellite cargo for the U.S. National Reconnaissance Office, from SLC-6, Vandenberg Air Force Base, California, US, at the start of a two hour launch window, at 02:00 GMT, on the 28th June.
The rocket will fly in a configuration with two strap-on solid rocket boosters. This is the first Delta 4 mission from the West Coast.
