# Henry E. Rohlsen Airport

Henry E. Rohlsen Airport (IATA: STX, ICAO: TISX, FAA LID: STX) is a public airport six miles (10 km) southwest of Christiansted on the island of St. Croix in the United States Virgin Islands. The airport is named after Henry E. Rohlsen, a St. Croix native who was one of the Tuskegee Airmen during World War II.
The airport, which was a hub for Aero Virgin Islands in the 1970s and 1980s, can receive jets up to the size of the Boeing 747s. Before 1996 the airport was known as Alexander Hamilton International Airport.

## History

During World War II, the United States Army Air Forces Sixth Air Force stationed the 12th Bombardment Squadron (25th Bombardment Group) at the airport for antisubmarine patrols flying B-18 Bolo aircraft from November 8, 1941, to November 10, 1942. During the time the military operated the airport, it was called Benedict Airfield. When the airport was transferred to civilian control, it was renamed to honor former St. Croix resident Alexander Hamilton.
Several airlines have operated scheduled passenger jet service to St. Croix in the past, including Air Florida with Douglas DC-9-10s, Caribair with McDonnell Douglas DC-9-30s, Continental Airlines with Boeing 727-200s, Eastern Airlines with Boeing 727-100s, 727-200s and 757-200s, Midway Airlines with Boeing 737-200s, Pan Am with Boeing 727-200s as well as wide-body Airbus A300B4s, and Trans Caribbean Airways with Boeing 727-200s. American Airlines has served St. Croix for many years. In 1974, American served the airport with Boeing 707 and Boeing 727-100 jetliners with nonstop flights to New York City. In 1994, American operated Airbus A300-600R wide-body jets into St. Croix with nonstop service to Miami. A Boeing 747 carrying relief supplies during the aftermath of Hurricane Marilyn landed at the airport in 1995. Satellite imagery shows the presence of C-17 and C-130 military transports in 2006 and 2015.
On November 11, 2018, the world's second-largest cargo airplane, the Antonov An-124, landed on St. Croix to deliver building supplies for houses as part of the hurricane recovery.

### Terminal modernization and expansion project

In August 2018, the Virgin Islands Port Authority (VIPA) held a charrette to announce and discuss the terminal's expansion and renovation. On March 14, 2019, the VIPA announced that bidding for phase one of the upgrade project would be in September. The renovation was expected to be complete within a year.
VIPA had begun the Henry E. Rohlsen Airport Terminal Expansion and Modernization Project as of September 2020. The improvements to the terminal will be completed in four phases over a six-year period.
Phase one entails enclosing 5,500 square feet of walkway space to increase the lounge's seating capacity, refurbishing the existing passenger lounge space and restrooms, enclosing the 1,100-square-foot open-air gardens with a new roof structure to provide additional concessions space, and upgrading the mechanical systems for the additional air-conditioned area.
Phase one is estimated to cost $8.6 million and was funded by a $7 million grant from the U.S. Department of Commerce Economic Development Administration in 2019 with a local match of $1.6 million from the VI Port Authority. The construction was anticipated to take 18 months and end in March 2022, but was ahead of schedule and ended on December 21, 2021.
Phases two through four include the addition of a second level to accommodate jet bridges, additional hold room, concession and retail space, improvement of passenger flow and baggage handling in the terminal; redesign, expansion, and modernization of the interior of the terminal to make the best use of the existing floor plan; the addition of tropical landscaping; and changes to improve the flow of vehicular traffic. Expanding the terminal will allow St. Croix to take full advantage of its 10,000-foot runway.
While Phase 1 of the HERA Terminal Expansion is fully funded, VIPA is actively seeking funding sources for Phases 2 through 4. The project is estimated to cost $140 million.
