UNITED STATES NAVAL AVIATION 1910-1995
1937-Continued
efforts in standardization changed from a part-time
program of annual conferences to one employing a
joint staff of officers and civilians on a full-time basis.
15 March The Bureau of Aeronautics assigned dis-
tinguishing colors to each aircraft carrier for use as tail
markings by all squadrons on board, thereby changing
the existing practice of assigning colors to squadrons
and eliminating the confusion resulting when
squadrons transferred from one carrier to another.
21-22 June Patrol Squadron 3, with 12 PBY-l
Catalinas under the command of Lieutenant Robert W.
Morse, flew nonstop from San Diego, Calif., to Coco
Solo in the Canal Zone, completing the 3,292-mile
flight in 27 hours and 58 minutes.
30 May A contract was issued to the Martin
Company for the XPBM-I two-engined flying boat
patrol plane. The aircraft was the initial prototype in
the PBM Mariner series of flying boats used during
and after World War II.
1 July The system of designating squadrons was
revised to provide for numbering each carrier
squadron according to the hull number of its carrier,
each battleship and cruiser squadron the same as the
number of its ship division, each Marine Corps
squadron according to its Aircraft Group, and patrol
squadrons serially without regard to assignment. The
change also abolished the use of suffix letters to indi-
cate organizational assignment, except for Naval
District and Reserve squadrons, and interposed the M
for Marine Corps squadrons between the V prefix and
mission letters.
2 July The Navy agreed to accept transfer of Army
airships and lighter-than-air equipment. Included in
the transfer were the airships TC-13 and TC-14, used
for antisubmarine patrol in the early stages of World
War II.
15 July The Ship Experimental Unit was placed in
operating status at the Naval Aircraft Factory and made
responsible for development and testing of equipment
and techniques for carrier landings. This unit consisted
of officers and men which were transferred from NAS
Norfolk, Va., where this function had been performed
since 1921.
6 August A contract was issued to Goodyear for
two new non-rigid airships, the L-l for training pur-
poses, and the K-2 for coastal patrol.
9 August The contractor's demonstration flights of
the XOZ-I rotary-winged aircraft, which included a
water takeoff, were completed at the Naval Aircraft
Factory. Pennsylvania Aircraft Corporation had modi-
fied this aircraft from an N2Y-l trainer into an experi-
mental gyroplane by installing a new engine and a
rotary wing with cyclic control.
9 September The XPBS-l, a four-engined mono-
plane flying boat built by Sikorsky Aircraft, made its
first flight. This aircraft, constructed as a long-range
patrol plane, was later used as a transport.
30 September
Norfolk, Va., with
command.
Yorktown was commissioned at
Captain Earnest D. McWhorter in
1 October Patrol aviation with its tenders was trans-
ferred from Base Force and assigned to the reestab-
lished type command, Aircraft Scouting Force. With
the change, five Patrol Wings, numbered 1 through 5,
were established as separate administrative commands
over their assigned squadrons.
17 December The XPTBH-2, a twin-float seaplane
designed by Hall Aluminum Aircraft Company, Inc. for
patrol and torpedo attack, was accepted by the Navy.
This was the last twinfloat torpedo plane developed
for the Navy.
23 December A successful unmanned radio-con-
trolled flight was made with a JH-l drone, at the
Coast Guard Air Station, Cape May, N.J. Takeoff and
landing were made using a landbased radio set; for
flight maneuvers, control was shifted to an airborne
TG-2.

21 April The delivery of the XF2A-l to the Langley
Memorial Aeronautical Laboratory of the National
Advisory Committee for Aeronautics marked the initia-
tion of full-scale wind tunnel tests to determine means
of decreasing aerodynamic drag and thereby increas-
ing high speed. These tests, conducted at the recom-
mendation of Commander Walter S. Diehl, indicated
that the speed of the XF2A-l could be increased 31
mph over the 277 mph already achieved, and led to
the utilization of this technique in other high-perfor-
mance aircraft, by both the Army and the Navy. The
data thus obtained was also directly applicable to the
design of new aircraft.
12 May Enterprise was commissioned at Newport
News, Va., Captain Newton H. White commanding.
