Facet Block Injection in Richmond Heights, FL

At the beginning of World War II, the United States Navy purchased 2,500 acres (1,000 ha) of land in southwestern Dade (now called Miami-Dade) County, Florida for the purpose of constructing an airship base. The land was owned by the Richmond Timber Company, a major supplier of Dade County Pine (a denser, harder, sub-species of Pinus Palustris, or Long Leaf Pine). The base was named Naval Air Station Richmond, after the lumber company and was home to the 25 ships of ZP-21(Patrol, Airship Squadron 21 and Airship Wing 2). NAS RICHMOND was the second largest airship base in the United States, NAS LAKEHURST being the largest. NAS RICHMOND was destroyed by a hurricane and fire in September 1945.

After the end of World War II, Captain Frank C. Martin, a Pan American pilot, purchased farm land adjacent to the base in rural southwest Dade County. With this purchase he created Richmond Heights, as a new community for returning African American Veterans.

Of the original 2,500 acres (1,000 ha) he purchased in 1949, the Federal Government used eight hundred acres to build the headquarters of Naval Air Station Richmond, a blimp base constructed in the early months of World War II Richmond, and was eventually home to 25 K-series blimps, three hangars, and 3,000 men. The hangars were 16 stories tall, built of Douglas fir brought in by train. The blimps protected ship convoys in the Florida Straits, and Richmond was the headquarters for the fight against U-boats operating in the Caribbean.
