Introduction
BATTERY COMPARTMENT
1-12. Located on the bottom of the main housing, the battery compartment (Figure 1-9) houses the
nonrechargeable BA-5590/U or the rechargeable BB390A battery (for training use only). The same
battery is used in the single-channel ground and airborne radio system (SINCGARS) and can be
interchanged with the CLU. A connector on the battery compartment joins to a corresponding
connector on the battery. A wire bail holds the detachable battery compartment cover in place.
Figure 1-9. Battery compartment.
DAYSIGHT
1-13. The daysight works much like a telescope and consists of a lens, status indicators, and an
eyepiece (Figure 1-10). The daysight—

NIGHT VISION SIGHT
1-14. The NVS is the primary sight used by the gunners (Figure 1-11) during the day or night. This
imaging infrared (I2R) system allows the gunner to see during limited visibility conditions, including
darkness, obscuration, smoke, fog, inclement weather, and IR clutter. The NVS operates by converting
an IR target image to a visible light image for the gunner. The NVS consists of the NVS lens, a
detector dewar cooler (DDC), a CLU display, and an eyepiece that provides the gunner with both 4x
wide field-of-view (WFOV) and 9x narrow field-of-view (NFOV) magnification for scanning and
target detection.
Figure 1-11. Night vision sight lens.
Detector Dewar Cooler
1-15. The DDC (Figure 1-12) cools the NVS to the proper operating temperature and converts IR
energy to electrical signals. These signals are sent to the CLU display by way of the signal processor to
provide the gunner a picture of the target area.

Introduction
Command Launch Unit Display
1-16. Similar to a miniature television, the CLU display is used to make the WFOV, NFOV, and
seeker IR images visible to the gunner.
1-17. The green, amber, and red icon indicators (Figure 1-13) that surround the CLU display identify
operational modes, conditions, and malfunctions. Visible during day and night use, these indicators
provide the gunner with continuous feedback on missile readiness or possible system malfunctions. All
indicators will be explained in detail in Chapter 2.
Figure 1-13. Status indicators.
Eyepiece
1-18. The eyepiece (Figure 1-14) allows the gunner to see the CLU display. Through the eyepiece, the
gunner sees the DAY FOV, WFOV, NFOV, seeker FOV, and the status indicators. The eyepiece
consists of a lens assembly, eyecup, and diopter adjust ring.

Test Connector
1-19. The test connector (Figure 1-15) is used to perform field- or higher-level maintenance and to
interface with the FTT.
Round Interface Connector
1-20. The round interface connector (Figure 1-15) provides the electrical connection between the CLU
and the round.
Humidity Indicator
1-21. The humidity indicator (Figure 1-15) displays the quality of the air inside the CLU (white or
blue within acceptable levels; pink requires maintenance).
Figure 1-15. Test connector, round interface connector, and humidity indicator.
ROUND
1-22. The round consists of the LTA, the BCU, and the missile (Figure 1-16). The LTA interfaces with
the CLU and serves both as a handling container and launch platform for the missile. The LTA consists
of a launch tube, forward and aft end caps, carry handle, shoulder strap, CLU interface connector, and
shoulder pad.
NOTE: The round has a 10-year shelf life. The only maintenance requirement is stockpile
surveillance.
LAUNCH TUBE
1-23. The launch tube houses the missile. It is a single-piece, composite graphite/epoxy design. The
launch tube protects the missile from the environment before the missile is launched. All other LTA
components mount externally on the tube.
NOTE: Once the missile is launched, the LTA is discarded.
END CAPS
1-24. Two end caps protect the missile from damage during transport and handling.

Introduction
Forward End Cap
1-25. The forward end cap (Figure 1-16) protects the seeker dome from moisture, dust, and other
elements that could harm it. The forward end cap is removed when preparing for launch. The pressure
release valve is used to reduce the pressure in the LTA so the forward end cap can be removed.
NOTE: If the missile is not fired, ensure that the LTA is clear of debris, and replace the
forward end cap to protect the seeker dome.
Aft End Cap
1-26. The aft end cap (Figure 1-16) is permanently attached to the LTA. The center of the cap is blown
out by the launch motor blast during launch.
CARRY HANDLE
1-27. The carry handle (Figure 1-16) is used to lift and carry the round.
Figure 1-16. Launch tube assembly, end caps, and carry handle.

Introduction
BATTERY COOLANT UNIT
1-31. The BCU (Figure 1-19) consists of a battery section and a compressed-gas coolant section.
Before missile launch, the battery section powers the missile electronics, and the coolant section cools
the missile seeker to its operating temperature. The BCU is a single-use unit with 4 minutes of
operating time; it is not rechargeable. Once the missile has been fired, the spent BCU is discarded with
the LTA.

Chapter 1
MISSILE OPERATION
1-33. The missile consists of the guidance section, the mid-body section, the warhead, the propulsion
section, and the control actuator section (Figure 1-21).
GUIDANCE SECTION
1-34. The guidance section (Figure 1-21) provides target tracking and flight control signals. It is the
forward section of the missile and includes the seeker head section and the guidance electronics unit.
Seeker Head
1-35. The seeker head section, known as the seeker, contains the missile I2R system and the contact
switches used to detonate the warhead. The missile I2R system gives the missile its fire-and-forget
capability. During flight to the target, the missile I2R system tracks the target and sends target location
information to the onboard guidance electronics unit.
Guidance Electronics Unit
1-36. The guidance electronics unit serves two functions. It controls the seeker head so that it looks at the
target, and it sends signals to the control actuator section to guide the missile to the target during flight.
Figure 1-21. Missile guidance section.
MID-BODY SECTION
1-37. The mid-body section includes the missile skin; electronic safe, arm, and fire unit (ESAF);
wings; and the main charge of the warhead (Figure 1-22).
Missile Skin
1-38. The missile skin is a structural part of the missile and provides environmental protection for the
internal components during flight.
Electronic Safe, Arm, and Fire
1-39. The ESAF is the principal safety device that prevents accidental ignition of the motors and
accidental warhead detonation. The ESAF consists of circuits and two detonators
(one for the
precursor and one for the main charge). The ESAF controls missile launch sequence and warhead
detonation. It permits starting the rocket motors in the proper sequence when the gunner pulls the fire
trigger and all other firing conditions have been met. When the missile hits the target, the ESAF
detonates each warhead charge in sequence.

Introduction
Wings
1-40. The wings provide lift and keep the missile stabilized during flight. The wings fold into slots in
the missile skin when the missile is in the LTA and deploy into flight position after clearing the LTA.
Figure 1-22. Mid-body section.
WARHEAD SECTION
1-41. The Javelin missile uses a dual-charged warhead (Figure 1-23). The warhead has a precursor
charge and a main charge.
Precursor Charge
1-42. The precursor charge is a high-explosive (HE) shaped charge. Its purpose is to cause the target's
reactive armor to detonate before the main charge reaches the armor. Once the reactive armor is
penetrated, the target’s main hull is exposed to the warhead’s main charge. If the target is not equipped
with reactive armor, the precursor charge provides additional explosives to penetrate the main armor.
Main Charge
1-43. The main charge is the second charge of a dual-charge warhead and is also an HE shaped charge.
The primary warhead charge is designed to penetrate the target’s main armor to achieve a target kill.

Chapter 1
PROPULSION SECTION
1-44. The propulsion section (Figure 1-24) consists of the launch and flight motors.
Launch Motor
1-45. The launch motor propels the missile out of the LTA. It provides the initial force to push the
missile a safe distance from the gunner before the flight motor ignites to ensure the gunner’s safety.
The launch motor is completely spent by the time the missile clears the LTA, this accounts for the low
signature after launch.
Flight Motor
1-46. The flight motor powers the missile to the target during flight. It ignites when the missile is a
safe distance from the gunner, protecting the gunner from hot exhaust gases generated when the motor
fires.
Figure 1-24. Missile propulsion section.
CONTROL ACTUATOR SECTION
1-47. The control actuator section (Figure 1-25) maneuvers the missile during flight and provides
internal electrical power. The control actuator section consists of four control fins, four thrust vector
control (TVC) vanes, and a thermal battery.
Control Fins
1-48. The control fins maneuver the missile during flight. The spring-loaded fins automatically deploy
and lock into flight position after the missile clears the LTA. During flight, they adjust automatically to
guide the missile to the target.
Thrust Vector Control Vanes
1-49. The TVC vanes aid the control fins in maneuvering the missile during flight by deflecting the
flight motor exhaust. This control changes the angle of thrust from the flight motor, resulting in a
change to the missile’s flight path.
1-16
FM 3-22.37
20 March 2008
Introduction
Thermal Battery
1-50. The thermal battery provides internal electrical power for the missile during flight. It is sealed in
the body of the missile.
Figure 1-25. Control actuator section.
CAPABILITIES AND FEATURES
1-51. The missile has two gunner-selectable attack modes: top or direct. Each mode has its own flight
path or profile for reaching the target.
TOP ATTACK MODE
1-52. The top attack is the default mode when the missile seeker is first activated. In the top attack
mode, the missile approaches from above to impact and detonate on the top of the target (Figure 1-26).
This capacity allows the gunner to attack a vehicle from the front, rear, or the side and greatly
increases the probability of a kill. Vehicles usually have less protection on top. The minimum
engagement distance is 150 meters.
Figure 1-26. Top attack mode.
20 March 2008
FM 3-22.37
1-17
Chapter 1
1-53. The exact profile of the missile flight path depends on the range to the target and is determined
automatically by the missile’s onboard software). When firing at a 2,000-meter target, the missile
reaches a height of about 160 meters above the battlefield (Figure 1-27). If the target is under a
protective structure, using the top attack mode will cause the missile to detonate on the structure
instead of on the target. The gunner can select the direct attack mode to counter targets hiding under
protective cover.
Figure 1-27. Top attack flight path.
DIRECT ATTACK MODE
1-54. The direct attack mode can be selected only after seeker cooldown and before lock-on. The
gunner pushes the attack select (ATTK SEL) switch on the right handgrip to change attack modes. In
the direct attack mode, the missile flies on a more direct path to the target. The missile impacts and
detonates on the side (front, rear, or flank) of the target (Figure 1-28). The minimum engagement
distance is 65 meters.

Introduction
1-55. The exact profile of the missile flight path shown in a general configuration in Figure 1-29
depends on the range to the target and is determined automatically by the missile’s onboard software.
With a 2,000-meter target, the missile reaches a height of about 60 meters above the battlefield. This
path allows the missile to reach a target under a protective structure.

CONTROLS AND OPERATION
This chapter is an overview of the Javelin’s controls and indicators, operation of
the Javelin, and CLU display indicators.
CONTROLS AND INDICATORS
2-1. The Javelin controls allow the gunner to perform and monitor all operations. The controls are
located on the handgrips except for the diopter adjust ring and the power switch.
DIOPTER ADJUST RING
2-2. The diopter adjust ring is located on the CLU eyepiece assembly (Figure 2-1). The gunner uses
the diopter adjust ring to adjust the focus of the image. Any gunner with vision correctable to 20/20
can use the CLU to see an in-focus image without using glasses. The alignment mark is located on the
eyepiece. Align the number that corresponds with the adjustment. This adjustment is constant on all
CLUs.
Figure 2-1. Diopter adjust ring.
POWER SWITCH
2-3. The power switch is a rotary switch located on the lower rear corner of the left-hand side of the
CLU main housing (Figure 2-2). The power switch controls the Javelin’s mode of operation and each
position brings different components of the Javelin into operation. The power switch has four
positions: OFF, DAY, NIGHT, and TEST.

Chapter 2
Figure 2-2. Power switch positions.
OFF Position
2-4. The Javelin is in the OFF mode when the power switch is in the OFF position. In this mode, no
battery power is applied to the Javelin. The day field-of-view (FOV) can be used for surveillance and target
detection, but the NVS cannot be used and the seeker cannot be activated. The missile cannot be launched.
DAY Position
2-5. The Javelin is in the DAY mode when the power switch is in the DAY position. In the day
mode, power is applied to the CLU. In the day mode, there is a day FOV but no NVS.
NIGHT Position
2-6. The Javelin is in the NIGHT mode when the power switch is in the NIGHT position. This mode
gives the gunner the full Javelin capability. Once the NVS is cooled down (about 2.5 to 3.5 minutes),
the gunner selects WFOV, NFOV, and day FOV, which gives him the full missile capability.
TEST Position
2-7. The Javelin enters a built-in test (BIT) routine (Figure 2-3) when the power switch in the TEST
position. The power switch is spring-loaded when in the test position. When the gunner moves the
power switch to the TEST position, it then returns to the NIGHT position upon release.

Controls and Operation
Return to OFF
2-8. Before turning the power switch to OFF, the gunner must leave the power switch at DAY for at
least two seconds to allow the flipper mirror time to move to the power switch to the DAY position.
LEFT HANDGRIP CONTROLS
2-9. The left handgrip (Figure 2-4) has the following controls: the filter select (FLTR) switch, the
focus adjust (FOCUS) switch, the sight select (SGT SEL) switch, and the seeker trigger.
Function of Controls
2-10. These controls are used to assist the gunner in—
z
Conducting surveillance.
z
Detecting, classifying, and recognizing targets.
z
Determining target range.
z
Activating the missile seeker.
z
Reacquiring the target in seeker FOV.
z
Locking the missile seeker onto the target.
z
Assessing battle damage.
z
Activating system countermeasures.
Filter Select (FLTR) Switch
2-11. The FLTR switch (Figure 2-4) is the left switch on the left handgrip. This pushbutton switch is
used to select the NVS filter; once initiated, the NVS filter prevents the enemy from detecting the CLU.
Focus Adjust (FOCUS) Switch
2-12. The FOCUS switch (Figure 2-4) is the center switch on the left handgrip. This switch is a self-centering
toggle switch used to focus the image on the CLU display during NVS (WFOV or NFOV) operation.
Sight Select (SGT SEL) Switch
2-13. The SGT SEL switch (Figure 2-4) is the right switch on the left handgrip. This pushbutton
switch is used to select day FOV, WFOV, NFOV, or seeker FOV.

Seeker Trigger
2-14. The seeker trigger (Figure 2-5) is the trigger located on the fingergrip (front) side of the left
handgrip. This trigger activates the seeker, locks the seeker onto the target, and enables the fire trigger.
A trigger guard is provided to protect against accidental activation.
Figure 2-5. Left handgrip controls—seeker trigger.
RIGHT HANDGRIP CONTROLS
2-15. The right handgrip has the following controls: the attack select (ATTK SEL) switch, the gate
adjust/contrast and brightness (GATE ADJ/CTRS & BRT) switch, and the fire trigger (Figure 2-6).
These controls allow the gunner to—
z
Change the attack mode, if necessary.
z
Adjust the track gates so the seeker can lock onto the target.
z
Adjust NVS contrast and brightness.
z
Fire the missile.
Attack Select (ATTK SEL) Switch
2-16. The ATTK SEL switch (Figure 2-6) is the right switch on the two-switch console on the right
handgrip. This pushbutton switch allows the gunner to toggle between the top attack and direct attack
modes. The top attack mode is the default attack mode and is automatically selected when the seeker is
activated. To change the mode of attack, the gunner must be in the seeker FOV.
Gate Adjust/Contrast and Brightness (GATE ADJ/CTRS & BRT) Switch
2-17. The GATE ADJ/CTRS & BRT switch (Figure 2-6) is the left switch of the two-switch console
on the right handgrip. This self-centering switch moves up, down, left, and right. This switch serves
two functions depending on whether the CLU display image is from the NVS or the seeker.
Night Vision Sight
2-18. When a CLU image is displayed using the NVS (WFOV or NFOV), the gunner uses the GATE
ADJ/CTRS & BRT switch to adjust the contrast and brightness of the CLU display image. When the
NVS first comes up, both the brightness and contrast are electronically adjusted so that they require
