Launch Facility T-11 was an unmanned missile silo assigned to T-01 Missile Alert Facility and Tango Flight in the F.E. Warren missile field. The public Peacekeeper field listing identifies it as Francis E. Warren AF Missile Site T-11, PIN 8514, ILC GJAD, at 42-06-44, 104-52-03. That converts to approximately 42.112222, -104.867500 in Platte County, Wyoming, near Guernsey.

T-11 began as part of the F.E. Warren Minuteman force, later served in the Minuteman III field, and then became one of the launch facilities converted for the LGM-118A Peacekeeper under the 400th Missile Squadron. It is no longer an active missile facility. The Peacekeeper mission at F.E. Warren ended on 2005-09-19.

T-11 sat in open rural Platte County country north-northwest of the T-01 control site and generally south of Guernsey. The 2013 silo-elimination environmental assessment notes that the Laramie River is located about one mile north of LF T-11, giving this otherwise isolated launch-facility page a useful public landscape reference. The coordinate used here marks the former launch-facility location, not a public visitor site. No public access was confirmed; the site should be treated as private or otherwise restricted property unless current land records or posted access information show otherwise.

As a Launch Facility, T-11 was normally unmanned. Missile crews served at the associated T-01 Missile Alert Facility / Launch Control Center, while maintenance, communications, and security teams visited the launch facility as needed. Public exterior photos from 2013 show general views of the former launch-facility area.

T-11 is a decommissioned former Minuteman / Peacekeeper launch facility. The missile is gone, and the site was part of the broader New START-era disposal framework for former Peacekeeper launch facilities at F.E. Warren. Parcel-level current ownership and reuse were not verified.
