Jenner Bombing Target No. 29
The Navy built Jenner 12th Naval District
Target No. 29 as one of over thirty bombing and rocket targets
within the 12th Naval District in California and Nevada during
World War II. Target No. 29 was directly associated with Naval Auxiliary Air Station (NAAS)
Santa Rosa, which was approximately 20 miles to the east.
NAAS Santa Rosa was one of a dozen subordinate NAAS and Naval
Air Station (NAS) activities under the 12th Naval District, Naval
Air Bases at NAS Alameda. The 12th Naval District officially
established NAAS Santa Rosa on 29 June 1943, a year and a half
prior to acquisition of Target No.29. NAAS Santa Rosa had a total
of three subordinate range activities, including divebombing
and rocket targets:
Petaluma 12th Naval District Target No.
Jenner 12th Naval District Target No.
Stewarts Point 12th Naval District
Target No. 30
Before acquiring the property for the
Jenner bomb target, the Navy received approval from the Interdepartmental
Air Traffic Control Board (IATCB) for the target location at
N38°26' 00", W123°07' 00 on 26 July 1944 (though
given to the second, the coordinates are an approximation). Although
the 1.5-mile radius Danger Area for this site was published on
Aeronautical Charts as early as 7 December 1944, the Navy had
not received real estate rights to the site. By the 14th, the
targets for this site have been constructed and the area
is now suitably improved for use and condemnation proceedings
were requested for the Navy to take immediate possession of the
land. The Navy acquired leases for the two parcels of land on
29 December 1944.
Although aligned with NAAS Santa Rosa, the bomb and rocket targets
within the 12th Naval District appear to have been available
for use by the dozens of subordinate activities under the Naval
District command along with the Army.
The research found no documentation in regards to specifics of
the layout for Target No. 29, though a site map shows it to be
a single circular target. Typical 12th Naval District dive bombing
targets on land were suppose to consist of a 250 foot cleared
area, with an interior 50 foot radius, 4 foot wide, wooden plank
circle. The target center was to be a 12-foot square platform
with a 3-foot diameter bulls eye. A typical dive-bombing
target might also have additional markings along the two axes
in line with rake stations, thoughit appears that Target 29 did
not have rake stations. The aerial photo analysis confirmed this
Following the end of the war, NAAS Santa Rosa remained in service.
As of 8 January 1946, the Navy planned on temporarily retaining
Target No. 29. It remained in use by units from NAS Alameda and
NAAS Santa Rosa through February and had a tentative release
date of 30 June. However, both leases for the property were terminated
on 1 March 1946, prior to the lease expiration. The entire site
eventually became part of the Sonoma Coast State Beaches state
park in the Russian River/Mendocino District.
