Del Mar is a seaside resort community located 20 miles north of San Diego's North Island. The town is the location of the San Diego County Fairgrounds, the Del Mar Race Track, and the luxurious Del Mar Hotel. An unpaved military outlying field, known as San Dieguito Valley or Del Mar, existed one mile east of town as far back as the 1920's and possibly earlier. In June 1941, the Navy, previously leasing the airfield's 80 acres, purchased the property with the intention of building two hard-surfaced runways. When the cost of building a dike to prevent possible flooding by the San Dieguito River proved prohibitive at that time, the proposal was canceled and the airfield remained unimproved.
Wartime needs for a blimp facility to patrol the sea around San Diego, prompted the Navy's return to the site in 1943 to construct a small blimp base. Although Lt. Hugh Talford landed the first blimp there on July 1, 1943, the facility was not commissioned until August 8 as an auxiliary of NAS Santa Ana. The station was essentially identical in make-up to Santa Ana's other auxiliary at Lompoc, California consisting of a 500 by 1000-ft. asphalt mat with two mooring circles and barracks for 26 officers and 112 enlisted men.
Normally, Santa Ana's ZP-31 or Blimp Headquarters Squadron Three maintained a detachment of one to two K-ships at Del Mar. During the summer of 1944, MGM studios used the station to film segments of the motion picture, This Man's Navy. The typical implausible action feature of the day, the film ended in Burma -- Del Mar was the location for this segment. The film starred the late Wallace Beery, who had been made an honorary LCdr. and Naval Aviator in the 1930s in appreciation of his promotional contributions to the Naval Aviation Reserve at NRAB Long Beach.
On October 17, 1944, K-111 of Blimp Headquarters Squadron Three from Tillamook, Oregon crashed on Santa Catalina Island. Temporarily deployed to Del Mar, the fully armed blimp was conducting a night navigation training flight when it hit high terrain on the island. The blimp's depth charges and gasoline tanks exploded, killing five of its nine-man crew. In spite of this tragedy, duty at Del Mar must have been quite pleasant. One former blimp pilot recalled: "We'd get our orders for the next day's patrol from the end of the bar at the Hotel Del Mar."
On 16 January 1941 the Navy acquired 80.04 acres in fee from Swift and Company for use as a landing field in the San Dieguito Valley of San Diego County, southeast of the county fairgrounds.
The Navy originally acquired the property for use as an auxiliary airfield and emergency landing strip for NAS San Diego. After concluding that this field could no longer accommodate modern carrier aircraft, the site was designated in 1942 as an auxiliary air facility for lighter-than-air dirigible aircraft. The facility could accommodate two K-type blimps which were used in anti-submarine warfare along the western coast. Improvements to the site included 6 buildings, 5 ordnance magazines, a septic tank and sewer lines, a 12,000 gallon underground gasoline storage tank and pump, landing mat and roadways paved with asphalt and concrete, domestic water lines, and electrical services.
