Eastern West Virginia Regional Airport (IATA: MRB, ICAO: KMRB, FAA LID: MRB), also known as Shepherd Field, is a civilian-owned, public use airport located four nautical miles (5 mi, 7 km) south of the central business district of Martinsburg, a city in Berkeley County, West Virginia, United States. It is owned by the Eastern West Virginia Regional Airport Authority or EWVRAA. This airport is included in the National Plan of Integrated Airport Systems for 2011–2015, in which the Federal Aviation Administration categorized it as a reliever airport.The airport is mostly used for general aviation. The airport authority’s fixed base operator, MRB Aviation offers many services including Air Charter, Aircraft Management, Flight Training (with partner Bravo Flight Training), Aircraft Maintenance, Fuel Sales and Hangar Rentals. The EWVRAA has entered into a joint-use agreement with the West Virginia Air National Guard's 167th Airlift Wing (167 AW), having a presence since 1955 at the adjacent Shepherd Field Air National Guard Base. The 167 AW is an Air Mobility Command (AMC)-gained unit which began operating the Boeing C-17 Globemaster III aircraft in January 2015. Prior to receiving the C-17, the airport had hosted a fleet of larger Lockheed C-5A Galaxy transport aircraft since 2007.
Beginning in July 2006 and running through the fall of 2012, the airport underwent a major improvement program which included the removal of the secondary runway 17/35, an expansion to the primary runway 08/26, and the construction of larger parking areas needed to accommodate the C-5A Galaxy aircraft. This project also included the addition of a new Air Traffic Control tower, Aircraft Rescue and Firefighting station, and hangars for the C-5As, as the existing hangars designed to house the
Lockheed C-130H Hercules were grossly inadequate considering the size of the larger plane. Also in this time period was the construction of a new entrance to the base, three 80,000-square-foot hangars with a maintenance mall, base supply, operations facility, simulator facility, fuel facility and tank farm.In previous decades, the WVANG also flew many other aircraft types including the F-51 Mustang and F-86 Sabre fighters. The 167th Airlift Wing held an open house in conjunction with the Thunder Over the Blue Ridge Air Show on September 4 and 5, 2010. The United States Air Force Thunderbirds and the United States Army Parachute Team attended the show which drew a crowd of more than 80,000 people.
