On September 19, 2019 the first two of twenty F-35As were delivered to the Vermont ANG 134th
FS/ 158th FW ‘The Green Mountain. With the arrival of these aircraft, 17-5265 ‘VT’/‘158 FW’
(c/n AF-207) and 17-5266 ‘VT’ (c/n AF-208), the Vermont ANG became the first ANG to receive
the F-35A and the second operational wing in the USAF. In December 2019 three more F-35As
arrived at Burlington. Originally formed as the 158th FG (Air Defense) and allotted to the Vermont
ANG in 1956 the 158th eventually became the 158th FW in late 1995.
