Groton: Submarine Capital Aviation at the Gateway to Eastern Connecticut
Groton, Connecticut — home to General Dynamics Electric Boat, Naval Submarine Base New London, and Pfizer's flagship research campus — occupies a strategically vital position on the Thames River estuary in New London County. The town of 38,762 residents anchors one of America's most concentrated defense-industrial corridors, generating substantial aviation demand from submarine engineers, Navy personnel, and pharmaceutical researchers traveling domestically and internationally.
Groton-New London Airport (GON), situated just 3 nautical miles southeast of downtown Groton, serves the region as a general aviation facility maintained to commercial standards by the Connecticut Airport Authority. With two runways — a 5,000-foot primary strip and a 4,000-foot secondary — GON supports private aircraft, charter operations, and the Army National Guard's 1109th Theatre Aviation Sustainment Maintenance Group (TASMG), which conducts Army aviation maintenance and deployment support missions from the field.
For scheduled commercial flights, Groton travelers primarily choose between two regional airports. T.F. Green International Airport (PVD) in Warwick, Rhode Island lies 48 miles northeast — roughly a 53-minute drive via I-95 — and now ranks among the fastest-growing major airports in the United States, offering nonstop service on Delta, JetBlue, Southwest, American, United, Frontier, Allegiant, Breeze, and BermudAir to 38+ destinations. Bradley International Airport (BDL) in Windsor Locks, Connecticut, 61 miles west via I-95 and I-91, serves as Connecticut's primary commercial gateway with international service including Aer Lingus flights to Dublin.
Defense and Research Aviation: The Groton Corridor
Electric Boat — General Dynamics' submarine design and manufacturing arm headquartered in Groton since the early 20th century — drives a consistent flow of business aviation through the region. As the prime contractor and design yard for the Virginia-class attack submarine program and the next-generation Columbia-class ballistic missile submarine (targeted for 2027 introduction), Electric Boat's 8,277-person Groton workforce includes engineers, program managers, and defense officials requiring frequent travel to Navy installations, government procurement offices in Washington D.C., and partner facilities in Newport News, Virginia.
Naval Submarine Base New London, across the Thames River from downtown Groton, homeports 16 attack submarines and supports over 14,000 military and civilian personnel. The base's operational tempo generates steady demand for military and commercial aviation — officers rotating assignments, contractors visiting for systems integration, and congressional delegations touring America's primary East Coast submarine fleet.
Pfizer's 160-acre research and development campus in Groton, employing 3,400 scientists and support staff, adds a distinct pharmaceutical aviation layer. The facility — where drugs including Zoloft, Zithromax, Xalkori, and Xeljanz were developed — maintains global research collaborations requiring international travel, with Bradley International's Dublin service via Aer Lingus particularly relevant for European research partnerships.
Getting to the Airport from Groton
The most direct route to T.F. Green (PVD) runs north on CT-32 to I-95 North, crossing into Rhode Island before exiting toward Warwick — a straightforward interstate drive with no tolls in Connecticut. Bradley International requires a westbound I-95 journey through New Haven before heading north on I-91 through Hartford. Peak-hour traffic on the New Haven stretch of I-95 can add 20–40 minutes to the Bradley trip, making PVD the more predictable choice for morning departures.

Frequently Asked Questions — Groton, CT Airport Services
T.F. Green International Airport (PVD) in Warwick, Rhode Island is the most convenient commercial airport for most Groton residents, located 48 miles away via I-95 — approximately 53 minutes under normal traffic. Groton-New London Airport (GON) is only 3 nautical miles from downtown Groton, but has not offered scheduled commercial passenger service since 2004 and currently operates as a general aviation and Army National Guard facility.
No. GON has not had scheduled commercial airline service since US Air discontinued service in 2004. The airport is maintained to commercial standards by the Connecticut Airport Authority and has two runways (5,000 ft and 4,000 ft), but currently serves general aviation, charter operations, and the Army National Guard's 1109th Theatre Aviation Sustainment Maintenance Group. The Connecticut Airport Authority maintains the facility with an eye toward potential future commercial service restoration.
General Dynamics Electric Boat employees and Naval Submarine Base New London personnel most commonly use T.F. Green (PVD) or Bradley International (BDL) for commercial travel. PVD offers quick access to Washington D.C. (Reagan and Dulles), Newport News/Norfolk (for coordination with the other major submarine manufacturer), and major connecting hubs. Bradley offers direct international service to Dublin via Aer Lingus, useful for defense and pharmaceutical industry travel to European partners.
For most Groton travelers, T.F. Green (PVD) is the better choice: it is 13 miles closer (48 vs. 61 miles), has a more predictable drive avoiding New Haven's congested I-95 corridor, and offers a broad route network with 38+ nonstop destinations. Bradley International (BDL) is preferable when flying internationally — particularly the Aer Lingus Dublin route — or when specific airlines or nonstop routes are only available there. Southwest Airlines operates at both airports, offering price competition on common routes.
Groton lacks direct rail or bus connections to either PVD or BDL, making personal vehicles and rideshare services (Uber, Lyft) the primary options. Taxis and airport shuttle services operate from New London and Groton to both airports. Amtrak's Northeast Regional and Acela trains stop at New London station (across the Thames), providing rail access to New York Penn Station and Boston South Station, from which travelers can connect to JFK, LGA, EWR, or BOS for broader international service. The New London Amtrak station is approximately 10 minutes from downtown Groton via the Gold Star Memorial Bridge.
