Pease Air National Guard Base is a New Hampshire Air National Guard base located at Portsmouth International Airport at Pease in New Hampshire. It occupies a portion of what was once Pease Air Force Base, a former Strategic Air Command facility with a base-related population of 10,000 and which was home to the 509th Bomb Wing flying the General Dynamics FB-111A. Pease AFB was closed pursuant to 1991 Base Realignment and Closure Commission action, with the 509 BW transferring to Whiteman AFB, Missouri. In 1983, investigations had shown soil and water contamination with degreasers and JP-4 jet fuel, and in 1990 the base was put on the National Priorities List of superfund sites. As of 2015, after 25 years of the Pease Development Authority's work, Pease International Tradeport has 275 businesses employing close to 10,000 civilian workers.

The New Hampshire Air National Guard (NH ANG) is the aerial militia of the U.S. state of New Hampshire. It is, along with the New Hampshire Army National Guard, an element of the New Hampshire National Guard.
