Borrego’s Military Echoes

Borrego Springs is renowned for its serene deserts and pristine night skies, but beneath its tranquil surface lies a military past rooted deeply in the sands of time.

The Borrego Hotel, once an Emergency Landing Field and Bombing Range during World War II, stands as a testament to the area’s contribution to the nation’s wartime readiness.

Borrego’s Wartime Role

In 1941, as global conflicts escalated, the U.S. Navy selected the remote desert of Borrego Springs for military preparedness. The Borrego Hotel was transformed into a strategic site where pilots practiced vital skills such as high-altitude bombing and emergency procedures essential for combat.

The facility included a 250-foot by 2600-foot dirt runway and a distinctive bombing target marked by concentric circles, making it a significant training hub for the San Diego Naval Air Station.

The AT-11 Kansan was the typical aircraft used for bomb target practice. Learn more about this plane.

Military Legacy and Community Safeguarding

Post-war, the site continued under Navy use until 1955, after which it was returned to private hands. Today, the land is primarily recreational, but the imprints of history remain.

In keeping with the safety of the community, the U.S. Army Corps of Engineers has been involved in the environmental restoration of this Formerly Used Defense Site (FUDS), ensuring that the land, once a cradle of wartime activity, is now safe for public enjoyment.

The Corps’ efforts have included detailed investigations to identify and mitigate any residual hazards. Historical investigations conducted in the 1990s and 2010s confirmed the area’s use for military training, with findings of practice bombs and munitions debris.

This diligent work safeguards the community and preserves the integrity of Borrego Springs’ natural splendor.
