25 July Thirty P-40s and three primary training
planes of the 33rd Pursuit Squadron, Army Air Forces,
were loaded aboard Wasp at Norfolk, Va., for transport
to Reykjavik, Iceland.
28 July To establish a continuing organization for
training flight crews, the Chief of Naval Operations
directed that action be taken as expeditiously as prac-
ticable to provide additional gunnery and tactical train-
ing in the pilot training program; to establish within
the Atlantic and Pacific Fleets at Norfolk, Va., and San
Diego, Calif.; Advanced Carrier Training groups to
indoctrinate newly designated Naval Aviators in the
operation of current model carrier aircraft; and to
assign a number of patrol squadrons in each fleet the
primary task of providing familiarization, indoctrina-
tion, advanced gunnery and tactical training for new
flight crews.
28 July The Operational Training Squadron of the
Atlantic Fleet, and the Test, Acceptance and
Indoctrination Unit of the Pacific Fleet were redesig-
nated Transition Training Squadron, Atlantic and
Pacific, respectively.
29 July The Secretary of the Navy approved the
installation of a Radar Plot aboard carriers as "the
brain of the organization" protecting the fleet from air
attack. The first installation was planned for the island
structure of Hornet.
1 August A Microwave (AI-lO) radar developed by
the Radiation Laboratory and featuring a Plan Position
Indicator (PPI) was given its initial airborne test in the
XJO-3 at Boston Airport. During the test flights, which
continued through 16 October, Radiation Laboratory
scientists operated the radar and devised modifications
while naval personnel from Project Roger (usually
Chief Aviation Pilot C. 1. Kullberg) piloted the aircraft.
During the tests, surface vessels were detected at
ranges up to 40 miles; radar-guided approaches
against simulated enemy aircraft were achieved at
ranges up to 3.5 miles. Operational radars which were
developed from this equipment were capable of
searching a circular area and included the ASG for K-
type airships and the AN/APS-2 for patrol planes.
1 August The Bureau of Aeronautics requested the
Naval Research Laboratory to develop radar guidance
equipment for assault drones, both to relay target
information to a control operator and to serve as auto-
matic homing equipment. This marked the initiation of
radar applications to guided missiles.
6 August Patrol Squadrons 73 and 74 initiated rou-
tine air patrols from Reykjavik, Iceland, over North
Atlantic convoy routes.
6 August In recognition of the radical change which
radar was causing in the method of using fighters to
protect the fleet, the Chief of Naval Operations issued
a "Tentative Doctrine for Fighter Direction from
Aircraft Carriers" and directed that carriers and other
ships equipped with radar immediately organize fight-
er direction centers.
7 August The Chief, Bureau of Aeronautics issued a
preliminary plan for installing radar in naval aircraft.
Long range search radar (British ASV or American
ASA) was to be installed in patrol planes. Short range
search radar (British Mk II ASV modified for Fleet Air
Arm or American ASB) was to be installed in one tor-
pedo plane in each section commencing with the TBF
while space needed for search radar was to be
reserved in new scout-dive-bombers and scout-obser-
vation planes. Interception equipment, when available,
would be installed in some F4Us and a British AI Mk
IV radar was being installed in an SBD with a view to
its use as an interim interceptor. The plan also includ-
ed installation of appropriate radio altimeters in patrol
and torpedo planes, and recognition equipment in all
service airplanes.
5 September Artemus 1. Gates, Naval Aviator No.
65 and member of the First Yale Unit of World War I,
took the oath of office as Assistant Secretary of the
Navy for Aeronautics; the first to hold the office since
the resignation of David S. Ingalls in 1932.
9 September The Bureau of Aeronautics requested
the National Defense Research Committee and the
Naval Research Laboratory to develop an interceptor
radar suitable for installation in single engine, single
seat fighters such as the F4U.
1 October The Aviation Supply Office was estab-
lished at Philadelphia, Pa., under the joint cognizance
of the Bureau of Aeronautics and the Bureau of
Supplies and Accounts, to provide centralized control
over the procurement and distribution of all aeronauti-
cal materials regularly maintained in the general stock.
8 October Organizational provision for guided mis-
siles was made in the fleet by the establishment of
