To form a typical attack situation, the weapon,
pilot, and aircraft must perform as a complete weapons
system. The weapon uses aircraft electrical power (via
an umbilical cable that connects the weapon to the
aircraft) from the time electrical power is applied to the
aircraft until the aircraft reaches a speed of
approximately 180 knots. The automatic power
changeover circuit in the weapon then switches the
weapon to ram air turbine (RAT) generator power.
Basically, the guidance section of the weapon and
the aircraft system form a closed-circuit television
system. A television camera mounted in the nose of the
guidance section provides a picture of the area forward
of the aircraft and displays this information on a
television monitor located in the cockpit of the aircraft.
Additional circuits provide a cross-hair grid on the
pilot's television monitor, which is a pair of vertical and
a pair of horizontal lines. This intersection of horizontal
and vertical cross hairs (the square in the middle)
defines the tracking area. By looking at the video scene
displayed on the television, the pilot is able to boresight
the weapon and aircraft to acquire the target, initiate
lock-on, and confirm weapon tracking.
After boresighting the weapon, selecting the proper
fuze option, and achieving satisfactory lock-on, the
pilot initiates release and escapes the target area. The
weapon continues to track the target until it reaches the
point of impact.
The Walleye I Mk 27 practice weapon is identical
to the Mk 21 weapon except for the warhead and
control sections. The warhead is entirely inert, does not
contain a fuze or fuze booster, and has ballast to
maintain weapon CG (center of gravity) compatibility
with the Mk 21 weapon. This weapon is used for
captive-flight pilot training and for aircraft loading and
ground handling training purposes.
For further information concerning the Walleye I
guided weapon, you should refer to the Walleye I
Guided Weapon, NAVAIR 01-15MGA-1.
WALLEYE I ERDL.The Walleye I extended
range data link (ERDL) guided weapon consists of the
same basic items as the Walleye I. These weapons are
designed
to
be
used
in
conjunction
with
the
AN/AWW-13 data pod. They permit target information
to be transmitted between the weapon and data pod
before and after release of the weapon.
WALLEYE II.The Mk 5 tactical Walleye II
guided weapon consists of a guidance section, a fairing
assembly, a warhead section (including the fuze and
fuze booster), a control section, four wings, four fin
adapters, and four fins. The weapon has provisions for
30-inch suspension only, and is in the 2,000-pound
class weapon category. The Walleye II (series) weapons
are essentially the same as the Walleye I weapons
except they are physically larger in size and have
improved electronics. Functional operations of the
weapon and delivery tactics are basically the same as
Walleye I.
For further information concerning the Walleye II
(series) weapons, you should refer to the Guided
Weapon (Walleye II), NAVAIR 01-15MGB-2.2.
WALLEYE II ERDL.The Walleye II extended
range data link (ERDL) guided weapon Mk 23 Mods 0,
1, and 2 (frequency channels A, C, and E) consists of
the same basic items as the Walleye II Mk 5 weapons.
However, these assemblies include added data link
functions and extended range capability. The addition
of the larger wings enables the weapon to be launched
with longer slant ranges to a target complex. The
addition of the data-link pod (Guided Weapon
Control-Monitor Set AN/AWW-9/13) and a joystick
controller
(guided
weapon
control
group
OK-293/AWW) on the aircraft allow the pilot to
remotely steer the weapon to a specific target within the
complex with pinpoint accuracy.
The
Guided
Weapon
Control-Monitor
Set
AN/AWW-9/13, data-link pod (fig. 3-16) is the
communications link between the pilot and the weapon.
The
pod
is
suspended
from
a
standard
Walleye-configured bomb rack. It can be jettisoned in
an emergency. The pod contains the necessary
electronics to allow the pilot to receive the transmitted
video from the weapon and to transmit the command
signals to the weapon. In addition, the pod contains a
video tape recorder (VTR) that record the video
transmitted by the weapon all the way to impact on the
target. This allows low-cost weapon performance
monitoring, which can be played back for mission
evaluation or for training purposes.
