Evolved Expendable Launch Vehicle (EELV) is an expendable launch system program of the United States Air Force (USAF), intended to assure access to space for Department of Defense and other United States government payloads. The program, which began in the 1990s with the goal of making government space launches more affordable and reliable, resulted in the development of two launch systems, Delta IV and Atlas V. These two launch systems are the primary methods for launching U.S. military satellites. The USAF plans to use the EELV family of launch vehicles until at least 2030. Follow-on technologies, including a Reusable Booster System are being considered.

“As humans have a prior right to existence over dogs by virtue of being more highly evolved and having a superior consciousness, so women have a prior right to existence over men. The elimination of any male is, therefore, a righteous and good act, an act highly beneficial to women as well as an act of mercy.”
—Valerie Solanas (b. 1940)

The salients of colonial policy.
What is that to the white child hacked in bed?
To savages, expendable as Jews?”
—Derek Walcott (b. 1930)

and life departs, launch out, the fragile soul
in the fragile ship of courage, the ark of faith
with its store of food and little cooking pans
and change of clothes,”
—D.H. (David Herbert)
