Historical Background: Brief overview of the airport's origins and early development
The Portsmouth International Airport at Pease, located in Portsmouth, New Hampshire, has a rich history that dates back to the mid-20th century. Its origins are deeply intertwined with military operations, as the site was initially established as Pease Air Force Base in the 1950s. The base was named in honor of Captain Harl Pease, a New Hampshire native and Medal of Honor recipient from World War II. The U.S. Air Force selected the location due to its strategic position on the East Coast, and construction began in 1951. By 1956, Pease Air Force Base was fully operational, serving as a key installation during the Cold War, primarily housing the Strategic Air Command (SAC) and later the Air Mobility Command (AMC).
The early development of the airport was focused on military aviation, with the base accommodating large aircraft such as the B-52 Stratofortress and KC-135 Stratotanker. These aircraft played crucial roles in the nation’s defense strategy, including nuclear deterrence and aerial refueling missions. The base also contributed significantly to the local economy, employing thousands of military personnel and civilians. However, the end of the Cold War led to a reevaluation of military installations across the country, and Pease Air Force Base was identified for closure under the 1991 Base Realignment and Closure (BRAC) Commission.
Following the closure of Pease Air Force Base in 1991, efforts were made to repurpose the facility for civilian use. The Pease Development Authority (PDA) was established to oversee the transition, and in 1992, the Portsmouth International Airport at Pease officially opened for civilian operations. The airport retained much of the infrastructure from its military days, including a long runway capable of handling large commercial aircraft. This made it an attractive option for both passenger and cargo airlines, as well as general aviation.
During its early years as a civilian airport, Portsmouth International Airport focused on establishing itself as a regional aviation hub. It began offering limited commercial flights, primarily to destinations within the northeastern United States. Additionally, the airport became a center for cargo operations, leveraging its spacious facilities and strategic location. The former military hangars and buildings were repurposed to support a variety of aviation-related businesses, further diversifying the airport’s economic impact.
The airport’s development also included environmental remediation efforts, as decades of military use had left contamination on the site. Cleanup initiatives were undertaken to address issues such as fuel spills and hazardous waste, ensuring the safety and sustainability of the airport’s operations. By the late 1990s and early 2000s, Portsmouth International Airport had successfully transitioned from a military base to a thriving civilian airport, serving the Seacoast region of New Hampshire and beyond. Its history reflects a unique blend of military heritage and civilian innovation, making it a key component of the region’s transportation infrastructure.

Original Purpose: Initial role and function of the airport in Portsmouth, NH
The Portsmouth International Airport at Pease in Portsmouth, NH, has a rich history that dates back to the early 20th century. Originally, the site was not an airport but a military installation. The airport's origins can be traced to 1930 when the U.S. Army Air Corps established a presence in the area. However, the facility that would eventually become Portsmouth International Airport was officially opened in 1956 as Pease Air Force Base. The base was named after Captain Harl Pease, a Portsmouth native and Medal of Honor recipient from World War II.
The initial role of Pease Air Force Base was to serve as a Strategic Air Command (SAC) bomber base during the Cold War. It was home to the 509th Bombardment Wing, equipped with B-47 Stratojet bombers, and later, the 100th Strategic Reconnaissance Wing, which operated RB-36 Peacemaker and KC-97 Stratofreighter aircraft. The primary function of these units was to provide a nuclear deterrent and strategic reconnaissance capabilities, reflecting the geopolitical tensions of the era. The base played a crucial role in the nation's defense strategy, ensuring rapid response capabilities in the event of a nuclear conflict.
In addition to its military role, the base also had a significant impact on the local community. It brought economic stability to the Portsmouth area, providing jobs and supporting local businesses. The presence of the airbase also fostered a sense of national pride and security among residents. However, the primary focus remained on its military function, with the base operating as a key component of the United States' strategic defense network.
The transition from a military base to a civilian airport began in the late 1980s and early 1990s. Following the closure of Pease Air Force Base in 1991 due to Base Realignment and Closure (BRAC) Commission recommendations, efforts were made to repurpose the facility. The airfield was converted into a joint civilian-military airport, with the New Hampshire Air National Guard continuing to operate from the site. The civilian portion of the airport, now known as Portsmouth International Airport at Pease, opened for commercial use in 1993, marking a new chapter in its history.
The original purpose of the airport, as part of Pease Air Force Base, was deeply rooted in national defense and strategic military operations. Its transformation into a civilian airport while retaining a military presence highlights the adaptability of the facility. Today, Portsmouth International Airport serves both commercial and military aviation needs, but its initial role as a Cold War-era bomber base remains a significant part of its legacy. This history underscores the airport's importance not only to Portsmouth but also to the broader context of U.S. military and aviation history.

Early Infrastructure: Description of the airport's facilities at the time of opening
The Portsmouth International Airport at Pease in Portsmouth, NH, officially opened for civilian use in 1969, though its origins trace back to its establishment as Pease Air Force Base in 1956. At the time of its transition to a joint civilian-military airport, the early infrastructure reflected a blend of military functionality and emerging civilian aviation needs. The airport initially featured a single 11,321-foot runway (Runway 16/34), one of the longest in the region, designed to accommodate large military aircraft such as the B-52 Stratofortress. This runway remains a defining feature of the airport’s infrastructure to this day, enabling the facility to handle a wide range of aircraft, from small private planes to commercial jets.
Upon opening for civilian operations, the airport’s terminal facilities were modest, primarily serving general aviation and limited commercial flights. The original terminal building was a functional, no-frills structure with basic amenities, including a small waiting area, ticket counters, and baggage claim. Its design prioritized efficiency over luxury, reflecting the airport’s dual role as a military base and civilian airport. The terminal was equipped to handle a few hundred passengers daily, with limited retail or dining options, as air travel was still in its early stages of growth in the region.
The airport’s apron and taxiways were designed to support both military and civilian operations, with designated areas for parking and servicing aircraft. The apron could accommodate a mix of military planes, private aircraft, and small commercial jets. Fueling facilities were available, though they were initially geared toward military specifications, with adaptations made over time to cater to civilian needs. Maintenance hangars, inherited from the Air Force Base, provided ample space for aircraft repairs and storage, ensuring the airport could support a variety of aviation activities.
Navigation and safety infrastructure at the airport were state-of-the-art for the time, with precision approach systems and lighting installed to facilitate safe landings and takeoffs, particularly in adverse weather conditions. The control tower, originally built for military operations, was repurposed to oversee civilian air traffic, ensuring seamless coordination between military and civilian flights. This dual-use capability was a unique feature of the airport’s early infrastructure, setting it apart from purely civilian airports.
In addition to its aviation facilities, the airport retained much of the military base’s support infrastructure, including administrative buildings, barracks, and utilities. While these were not directly related to civilian operations, they contributed to the overall functionality and self-sufficiency of the site. The airport’s early infrastructure was a testament to its military heritage, adapted pragmatically to meet the growing demands of civilian aviation in the late 1960s and early 1970s. This foundation laid the groundwork for its eventual expansion and modernization in subsequent decades.
