Harper Dry Lake Airfield serves Lockhart, US.

Harper Dry Lake Airfield (US-3335) in Lockhart, California, was a site for secret flight test programs during the 1940s and 1950s,. Howard Hughes conducted flight tests for his D-2 prototype there in 1943, and Northrop developed flying wings, including the MX-334, at facilities on the lakebed,.

The airfield's closure date is not specified, but its operations ceased due to the termination of projects like the Northrop MX-334, which was impacted by a lack of more powerful rocket engines and a redirection of priorities. Today, the site is part of the Harper Lake Subregion, which is a mix of public and private lands, with some areas now occupied by solar plants,. Motorized vehicle access is restricted to marked routes, and cross-country OHV activities are prohibited.
