a representation of The Great Artiste. Air National Guard Base The majority of Pease AFB was transferred to the Pease Development Authority, who now operate Pease International Tradeport including Portsmouth International Airport at Pease. The remaining part of the former Pease AFB that remained under military control was transferred to the New Hampshire Air National Guard and renamed Pease Air National Guard Base with the 157 ARG designated as the host unit. With the introduction of the USAF "objective wing" concept into the Air National Guard in the early 1990s, the 157 ARG was redesignated to its current title as the 157th Air Refueling Wing (157 ARW) on October 16, 1995. On October 2, 2009, the 64th Air Refueling Squadron (64 ARS) was activated at Pease as the 157th's active-guard associate. This was the first time that an active duty Air Force unit had returned to Pease since 1991. In August 2014, the Air Force announced that the 157 ARW would become the first Air National Guard unit to equip with the new Boeing KC-46 Pegasus aerial refueling aircraft. The KC-46A was scheduled to enter the Air Force inventory during fiscal year 2016, with Pease ANGB to receive its first Pegasus after October 2017. By the end of 2018, a Weapons System Trainer, Boom Operator Trainer, and Fuselage Trainer for the KC-46A were installed at Pease. In early February 2019, it was announced that the 157 ARW would receive the new aircraft by the fall of 2019. The final KC-135 at Pease, serial number 57-1419, departed on March 24, 2019, for Goldwater Air National Guard Base in Phoenix, Arizona. The first KC-46A arrived at Pease on August 8, 2019. The 12th and final KC-46A was delivered on February 5, 2021. Incidents/accidents All noted aircraft were based at Pease AFB, unless stated otherwise.
