Command, and the 317th Airlift Group was created as the parent unit for Dyess' C-130 squadrons. At the same time, the 7th Wing was redesignated the 7th Bomb Wing. Despite this separation as units, both the 7th Bomb Wing and the 317th Airlift Group remained at Dyess. One of the many unique features of Dyess is its extensive collection of static military aircraft on display. Collectively known as the "Linear Air Park", it contains 30 aircraft from World War II to the present, many of them formerly based at Dyess, and is located along the base's main road, Arnold Blvd. All but one plane has been flown before. Its most recent addition is the first operational B-1B Lancer, known as The Star of Abilene, which made its final flight in 2003. It can be seen at the front gate to Dyess along with a recently retired C-130 Hercules located on the other side of the road (a tribute to the two main aircraft currently housed at Dyess). Another unique feature of Dyess is its main source of energy. In January 2003, Dyess became the first Department of Defense installation in the United States to be powered exclusively from renewable wind energy. Today, most of the energy Dyess receives is from other sources of renewable energy, such as biomass, and is considered one of the "greenest" bases in the USAF. The remnants of Tye AAF can still be seen today. Parts of the old runway still exist, as well as part of its parking area on the west side of Dyess. Global War on Terrorism The 7th Bomb Wing and 317th Airlift Group were called to duty once again shortly after 11 September 2001. Both played and continue to play vital roles in both Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Many of the 7th BW's B-1s and support personnel deploy to Southwest Asia. From there, the 7 BW provides close air support to troops in the field and precision strike missions with the B-1B Lancer. The 317th Airlift Group has been deployed continuously to Southwest Asia since December 2003, where the group provides airlift support to OIF, OEF, and Combined Joint Task Force-Horn of Africa operations. On 1 October 2015, Dyess became part of Global Strike Command. Role and operations The host unit at Dyess is the 7th Bomb Wing of the Global Strike Command, which was activated
