Bell's versatile Jet Ranger 206, a staple in
civilian aviation circles, drew the interest
of the Navy during the Vietnam War. Procured
in 1968 and designated the TH-57 Sea Ranger,
the helicopter remains the platform in which
all Navy, Marine Corps and Coast Guard
helicopter pilots are trained.
In 1968 the Navy took delivery of the TH-57
Sea Ranger, a derivative of the commercial
Bell Jet Ranger 206 and kin to the OH-58
Kiowa. Although primarily used for
helicopter flight training, these aircraft
were also used for photo, chase and utility
missions.
Following certification by the Federal
Aviation Administration in 1966, Bell
Helicopter Company's sleek, streamlined Jet
Ranger became an instant hit in the civilian
market with about 300 built by mid-1968. As
was often the case with aircraft designs,
civil success drew military interest. The
Army soon named the aircraft winner of a
reopened design competition for a light
observation helicopter and ordered 2,200
production versions, designating them OH-58
Kiowas. Deployed to Vietnam as early as
1969, the OH-58 served as a scout
helicopter, a role that advanced versions
continue performing today.
While the Army sent the Jet Ranger into
hostile skies, the Navy ordered its first
aircraft, designated TH-57As, as trainers to
supplement the famed UH-1 Huey then in use.
By the early-1980s, with the introduction of
the improved TH-57B and TH-57C versions of
the Sea Ranger, the latter featuring a full
array of instruments, the type had become
Naval Aviation's primary training
helicopter.
It has proven to be an exceptional trainer,
stable but very sensitive to control inputs,
especially rudder. Student Naval Aviators
find it challenging at first to smoothly
hover the aircraft, practicing over large
white box outlines painted on the surfaces
of outlying fields. The typical tendency is
to overcontrol initially, but then, sooner
or later, it happens, and students find
themselves hovering effortlessly,
demonstrating very fine control of the
aircraft, finally relaxed and able to
multitask. The TH-57 well prepares student
Naval Aviators for larger and heavier fleet
aircraft.
Prospective Navy, Marine Corps, and Coast
Guard helicopter pilots spend approximately
106 hours flying the Sea Ranger at Naval Air
Station (NAS) Whiting Field, Florida, before
receiving their wings. Over the course of
this period they learn aerodynamic and
engineering qualities of rotary-wing
aircraft and in particular, how to hover.
They also learn basic instrument techniques,
radio navigation, rough terrain landing,
night and formation flying, emergency
procedures like autotrotation, shipboard
operations, and helicopter tactics.
