Angel on the Yardarm: The Beginnings of Fleet Radar Defense and the
Kamikaze Threat
by John Monsarrat
Naval War College Press, 1985, 188 pages
The vice president of a New York advertising agency entered Naval Training
School in July 1942, and he served aboard the light aircraft carrier USS Langley
during many battles in the latter part of the Pacific War. Lieutenant John Monsarrat, a
radar specialist on the Langley, held the jobs of Intercept Officer and
Fighter Director Officer, responsible for guiding carrier fighter planes to
intercept enemy planes identified by radar. Monsarrat skillfully weaves his
personal experiences aboard the Langley from January 1944 to May 1945 with the
overall history of the Pacific War during the same period. Although the Langley
suffered relatively minor damage from only one kamikaze attack, the carrier's
crew witnessed numerous kamikaze attacks on nearby ships in the Philippines,
Ulithi, and Okinawa. The book also describes how Americans used radar time and again
to identify incoming planes, which usually allowed carrier planes to intercept
the Japanese far from intended targets.
After Monsarrat completed initial training, he worked as Director of
Editorial Research in the Bureau of Aeronautics in Washington, D.C. Here and in
his later positions he personally met many leaders of the Pacific fleet, so this
book contains several interesting comments on their personalities. Monsarrat's
experience in public relations for the Navy comes across in the
easy-to-understand language and clear chronological organization of this book's
22 chapters. The inside front cover of the book has a two-page map of the
Pacific that shows the track of the USS Langley between December 1943 and
June 1945 with a legend that briefly describes events in each location. The
back of the book includes a chronology of Monsarrat's service and a date log for
the Langley.
Many stories deal with radar (word from initials of "Radio
Detection and Ranging") used to determine the location of aircraft and
other ships. The incidents include the men who worked in the radar plot
(compartment), radar's successes in identifying and intercepting Japanese
planes, and some technical problems with radar. Although Monsarrat started in
public relations in the Navy, he dreamed of being assigned to an aircraft
carrier. In April 1943, he started training at the Pacific Fleet Radar Center in
Hawaii to qualify as a fighter director officer. In July 1943, he finally
achieved his dream when he was assigned to the carrier USS Langley, which
was in final stages of construction in Philadelphia prior to its
commissioning. The nine officers assigned to the ship's radar had responsibility to
supervise the installation of three radar sets, and they decided
on the arrangement of the equipment since no standard layout had been determined in those early days of the use of radar. They also had to
select 30 men who would work in radar plot, and one chapter gives the methods
used to assess whether enlisted men would have the temperament and skills to become
competent in radar work. These men needed patience for monotonous hours
looking over a radar set, analytical ability to interpret radar readings,
and quick decision making in the heat of battle.
A Japanese Zero from Formosa that hit the Langley with a bomb
on January 21, 1945, killed three and seriously wounded eleven when the plane's
bomb blasted a hole ten by fourteen feet in the flight deck. The plane narrowly
missed the flight deck and crashed into the sea. The pilot may have intended a
suicide attack and just missed the deck, but it is also possible that he tried
to escape after releasing his two bombs but ended up crashing after his plane
had been hit. The bombing of Langley provides a good example of
discrepancies in the number of kamikaze attacks reported by
various sources. The Japanese military determined the number of deaths in
Special Attack Forces, such as the Kamikaze Corps, based on whether planes had
orders for a suicide attack and did not return to base. Some of these planes
went into the sea far from their intended targets after being shot down or after
developing mechanical problems, but the men in these planes were included in the
recorded number of Special Attack Corps' deaths. The American side could only
estimate the number of kamikaze planes, since many times it could not be
determined with certainty whether planes intended suicide attacks or
conventional attacks.
The Langley's crewmembers witnessed the devastation of many kamikaze
attacks on nearby ships. For example, on March 11, 1945, while the Langley
was anchored at Ulithi with the crew watching a movie on deck, a Ginga
bomber (Frances) hit the carrier Randolph, killing 27 men and putting
huge holes in the flight and hangar decks. On January 21, 1945, after
Langley had been hit by a Zero's bomb, another Zero from the same
fighter group plunged into the deck of the carrier Ticonderoga with its
550-pound bomb, and then later a Hayabusa (Oscar) fighter hit the burning
carrier. Ticonderoga suffered extensive damage from these two suicide
attacks, with 143 killed, 202 wounded, and 36 planes lost.
The attacks on Langley and Ticonderoga illustrate some
problems encountered while using radar. The Langley radar men detected a
small group of bogeys (planes not yet positively identified as friendly or enemy
planes) 64 miles away and reported this to the task group fighter director on the
carrier Essex. The Washington, another ship in the same task group,
contradicted the information from the Langley and relayed a message that
the targets were friendly, which meant that it was thought that the planes were
emitting a top-secret Identification Friend or Foe (IFF) signal to indicate they
were friendly. Based on the contradictory reports, Essex decided to delay
sending combat air patrol (CAP) for several minutes, which allowed four kamikaze
planes and three escorts from Taiwan to approach the task group without
opposition and then make attacks on the Langley and the Ticonderoga. Apparently the Washington
gave incorrect information because of its inability to distinguish between
two groups of planes, one friend and one foe, that were approaching the task
group from the same general direction. Monsarrat explains that this costly mistake surely reinforced the
need for a group fighter director to not hesitate to dispatch planes to
intercept suspected bogies when there was a difference of opinion between the
radar readings of two ships.
Starting in March 1945, the Japanese sent many kamikaze planes from southern
mainland Japan against the American fleet off Okinawa. Through the early
identification of these planes by radar, American fighters shot down many planes before they got close to the task force. Monsarrat received the
Navy Bronze Star Medal with the following citation for his service during this
period:
For meritorious achievement as Fighter Director Officer of the U.S.S.
LANGLEY during operations against enemy Japanese forces in the vicinity of
Kyushu and Okinawa from March 18 to May 11, 1945. Exercising skill in the
performance of his duties, Lieutenant Monsarrat directed fighter planes in the
successful interception of fourteen separate enemy air attacks against our
forces, thereby contributing materially to the destruction of a large number
of hostile aircraft at a considerable distance from the Task Group to which
his ship was assigned. His tireless devotion to duty was in keeping with the
highest traditions of the United States Naval Service.

Several months prior to the Battle of Okinawa, Monsarrat submitted to Navy
officials his idea for using destroyers as radar pickets so that kamikaze planes
could be detected and intercepted far away from carriers in the task force.
Although he does not claim credit for being the only person to originate the
idea, the Navy successfully employed sixteen separate radar picket stations
around Okinawa, but the Navy still lost 30 ships sunk, primarily by kamikaze
attacks, and 368 ships damaged. These figures include many destroyers at radar picket stations.
Even though this book contains many stories about the use of radar and even
some descriptions of different types of radar, the book lacks a brief technical
explanation on exactly how radar works and the specific equipment involved. The
first part of the book contains a chapter on how the Langley officers selected men to
work in radar plot, but after that the author does not give any stories about individuals who worked there during battle. The reader could have had a better
understanding of their work if the author had included one or two examples of
how the men in radar plot worked together to identify planes and how this
eventually resulted in the downing of incoming Japanese planes.
Monsarrat's wartime memoir shows how radar played a critical role in the U.S.
Navy's successfully intercepting many kamikaze planes before they got close to
their intended targets. The book also gives readers a real sense of what
happened in the Pacific War from January 1944 to May 1945 as the carrier Langley
operated continuously in the most forward areas and participated in the key
battles during this period.
