According to the United States Census Bureau, Orange Grove has a total area of 1.1 square miles (2.8 km2), all land.

The BRAC decision to close Naval Air Station Chase Field near Beeville led to an increase in Pilot Training Rate (PTR) and the physical number of aircraft stationed at NAS Kingsville in Kleberg County.

In recognition of the increased congestion at Kingsville, the Navy made a significant investment in improving the facilities and capabilities of the Auxiliary Landing Field (ALF) at Orange Grove, about 5 miles (8 km) southwest of town.

The terminal airspace at Kingsville was expanded to include Orange Grove, and the ALF serves as an overflow relief from the primary airfield.

Hunting and fishing at NALF Orange Grove and Escondido Ranch is authorized in accordance with station directives and state and federal laws.

The South Texas Naval air station, in a partnership with the U.S. Geological Survey's Texas Gulf Coast Field Research Station, the Coastal Bend Bays & Estuaries Program, Texas A&M-Corpus Christi and the Coastal Bend Ambassadors, will offer an open field with artificial burrows for the burrowing owls, which are anticipated to stay there over the winter, beginning in October.
