Camp Malibu
(Point Dume Radar Site B-36 )
Camp Mailibu: Pyramidal tents are erected at Site 8 for the SCR-6l5-B trainees. The Jamesway Hut in the center is the site orderly room.
Originally established as air defense radar site B-36 under the Los Angeles Control Group. An SCR-270B radar was operated by the 654th Signal Aircraft Warning Company. It was later changed to a Sub-Post of Camp Pinedale as a training area of the Army Air Force's Western Signal Aviation Unit Training Center. This site was so secret that it does not show up any official Army, Army Air Forces or 9th Service Command station lists. Despite its name, the site is actually inland from Point Dume

Radar Training Sites

Captain Alfred L. Coffman, Captain Theodore R. Gwillim, and First Lieutenant Joseph M. Quinn arrived from the Aircraft Warning Unit Training Center, Drew Field for temporary duty at Western Signal Aviation Unit Training Center (WSAUTC) on 11 January 1945 to coordinate the selection of radar training sites in the Central Valley and on the Pacific coast. Laton, ten miles north of Hanford, CalIfornia, was chosen as the Valley site because of its excellent radar techniCal features. On 14 February 1945 the footing forms were poured for inallation of an SCR 615-A (height finding radar set) .. Two days later equipment installation was begun on two other sites at Laton for radar sets SP-1M, AN/TPS-1 and SCR-270. Laton was obtained as a camp site for WSAUTC by clearance lease.

On 12 March 1945 First Lieutenant M., B. Luke, ground reporting equipment advisor to the Director of Operations, accompanied the Deputy Base Commander and the Supervisor of the Tactical Unit Training Department (TUTD) on a trip to Visalia, California, to determine the training facilities available there. It was decided that these facilities were superior to those at Laton, which lacked living oonveniences, and therefor the training sites at Laton were moved to Visalia. Visalia had been used previously by WSAUTC. Facilities were made available for radar training at this sub-base of Hammer Field.

The coastal site selected for the individual replacement training (IRT) and cadre training program was at Malibu, approximately ten miles east of Santa Monica. This site was a fixed radar installation (Radar Site B-36) of the Los Angeles Control Group, but during the first five months of 1945 WSAUTC training facilities grew to such an extent that they overshadowed the Los Angeles Control Group.
Field Organization of IRT and Detachments

In the new air warning training program it was necessary to provide an organization to contaln the overhead personnel necessary to train and administer those aircraft warning detachments and individual replacement trainees who underwent final phases of operational training at Visalia and Malibu Beach. Flight B of Squadron T-2, 462nd Army Air Forces Base Unit (AAFBU), was formed and placed under the command of Captain John F. Meskiel formerly f'ield coordinator.. Flight B was composed of two detachments of about 65 men each, and further divided into training sites under the direction of TUTD:

Detachment No.1:
Visalia Army Air Field - Captain Maris L Ward, Commanding, Sites 1,2,3, and 4, each with one SCR-615, AN/TPS-1, AN/CPS-5, SP-1M .

Detachment No.2:
Malibu Beach - Captain Dale E Repp, Commanding, Sites 5,6, and 7 with two SP-1Ms and one AN/TPS-1.

After the required course was completed at Detachment No. 1, following ground individual training, the trainees were sent to Detachment No. 2 for the final phase operationnl training, prior to overseas shipment.
The first group of aircraft warning cadres, from the 49th and 52d Signal Aircraft Warning Detachments, were sent from Camp Pinedale to the Malibu Training Site, on 11 March 1945. The initial group was composed of cadres 1 through 12 (AN/CPS-1B), 49th Signal Aircraft Warning Detachment, and cadres 1 through 5 (SP-1M), 52nd Sienal Aircraft Warning Detachment.

Change in Organization

Camp Malibu, operated by the WSAUTC at Malibu Beach, California, remained in operation during the three-months' period from 1 June 1945 through 2 September 1945.. However, a change in organization occurred on 21 June 1945 when Squadron G, 462nd AAFBU. Camp Pineciale, was activated to handle the training program at Camp Malibu. Prior to the activation of Squadron G, Detachment 2, Flight B, Squadron T-2, 462nd AAFBU had been in charge of the training program at Camp Malibu. Inasmuch as all per sonnel, both trainee and overhead were already present for duty and the prescribed training were in progress, the change in organization affected only the orderly room, and was made to facilitate the handling of administrative and personnel problems of the trainees. The activation of Squadron G meant that most problems, of an administrative and personnel nature, could be solved at Camp Malibu instead of being referred back to the parent organization at Camp Pinedale.
Captain Randall J. Thumm, Comrnanding Officer of Detachment 2, Flight B, Squadron T-2, 462nd AAFBU was and was assigned to Squadron G and appointed Commanding Officer thereof.
G Squadron was established at Camp Malibu on 21 June 1945. It contained the overhead personnel for the training site. Personnel for the squadron were drawn from sources under the control of the WSAUTC. The Cormnanding Officer was Captain Randall J. Thumm.

G Squadron was aasigned to the Troop Commander but was under the supervision of WSAUTC TUTD for training purposes.

The strength of the squadron consisted of one officer and sixty-three enlisted men on 30 June 1945; one officer and seventy-four enlisted men on 31 July 1945; and one officer and seventy-one enlisted men on 31 August 1945.

Relationships with WSAUTC Staff Sections

Responsibility for the proper accomplishment of Squadron G's mission and the training of personnel was to the Commanding Officer WSAUTC, through the WSAUTC Executive Officer.

Tactical and operational supervision carne through the supervisor of the Team and Unit Training Division (TUTD) of WSAUTC, rooster training plans, operational directives, and the control of technical equipment, under the supervision of the TUTD. The latter agency also controlled the movement of trainee personnel and acted as a coordinating section in the movement of overhead personnel.

The original supply of communications, radar and equipment, was obtained through the Director of Maintenance and Supply, WSAUTC. Special items necessary to the performance of the tactical missions were also supplied to Squadron G buy the office of the Director of Supply, WSATUTC.

The supervision of the use of forms and publications, records of overhead personnel, and legal service, came through the office of the Director of Administration, WSAUTC.


A new marming table for Squadron G was authorized on 18 July 1945. Authority for the allotment of personnel to Camp Malibu was contained in a letter from Colonel W. H. MacDonald, Commanding Officer of the WSAUTC, to the Commanding Officer, Camp Malibu. Personnel thus allotted consisted of eleven officers and seventy enlisted men, and included an additional automobile equipment mechanic, as requested by Squadron G.


During the period from 1 June through 2 September 1945, training was carried on at Camp Malibu in the following radar sets:

1. AN/CPS-1 microwave, early warning, long range, search radar set.
2. AN/CPS-4 ultra high frequency, height finding radar set.
3. AN/CPB-5 ultra high frequency, long range, search radar set.
4. AN/TPS-1B ultra high frequency, portable, light warning, medium range, search, radar set.
5. AN/TPS-10 mircrowave, portable, height finding, medium range, radar set
range, radar set.
6. SCR-615, T-l and B models, microwave, ground control interception, height finding, medium range, radar set.
7. SP-1M microwave, ground control inerception. height finding, medium range radar set.

Five sites at Camp Malibu were used at various times by Squadron G for purposes of instruction. From time to time radar set teams were moved from one site to another, except where there were fixed installations.

During August 1945 training dropped from normal activity on seven radar sets to operation of only one, the AN,/CPS-5. Individual replacement training on radio equipment:; continued as usual, however, which was the status of the base as of 2 September 1945.

Research Report on Point Dume, California
by Bolling W. Smith
This research was complicated by the lack of basic data: names of installations, using services, etc. What little information was available was based on undocumented local history.
Information obtained from local authorities in California was sketchy and contradictory. It is known that there were several military installations at Point Dume, California, during (and after) World War II.
The most significant installation, and the one for which the most documentation was found, was an Aircraft Warning Service radar, code named “B-36” (and, apparently also “B-8”), and “Site 51.” This was originally named “Triunfo Peak,” then simply “Triunfo,” and finally “Triunfo (Pt. Dume).” While no definitive documentation was found, Triunfo Peak is some distance inland, and it is believed that while this was the original location selected for the radar set, the set was actually constructed near the coast, as shown on a number of maps. This radar station was part of a national network of radar stations designed to identify enemy aircraft entering American airspace.
In addition to the radar, there was a VHF radio station used to coordinate and control Army Air Forces interceptors. This was in the same general area as the radar, but whether it was co-located is not known. Signal Corps records were complicated by frequently inconsistent nomenclature – due to both the newness of the equipment and the desire for secrecy. Radar was variously termed “Radio B,” “detector sets,” “SCRs,” and “D/F” (direction finding) stations, and sites were described by name or by one of several numbers.
In addition to the Signal Corps installations, there were two US Navy facilities. During WWII, the navy had a base on leased land. No detailed information on this site was located. Also, there was a postwar missile testing range at Point Mugu, CA, with an instrumentation station at Point Dume. This site was subsequently converted into parkland. This is supported by documentation.
It is reported that there was a US Coast Guard beach patrol site called Zuma Patrol Base at Point Dume, but no information was found concerning this facility.

Lastly, there was a target range at Point Dume, operated by the 37th AAA Brigade, US Army. This was termed the Point Dume Firing Point. A few references were found confirming this, and that 37mm automatic weapons were fired at this site. No description was found of what facilities, if any, were built there. It is assumed, although not expressly documented, that the 37th AAA Brigade rotated units to the firing point for training. Whether buildings were erected or troops were quartered in tents is not stated. No reference to weapons larger than 37mm was found.
