GENERAL INFORMATION

JAVELIN WEAPON SYSTEM

M98A1 NSN 1430-01-433-8019

THEORY OF OPERATION

SCOPE

Javelin is made up of the CLU and a one-time expendable round. The CLU is manportable, reusable, battery operated, and is the gunner's interface with the round. The CLU provides passive day/night surveillance, target detection, classification and recognition, battlefield damage assessment, CLU status, built-in test (BIT), and missile software storage capabilities. When a round is connected, the CLU provides missile status indication, missile software download, and launch capabilities.

CLU OPERATION

The CLU has four modes of operation: OFF, DAY, NIGHT, and TEST. The operational modes are controlled by the power switch.

(50)

CLU OPERATION – (Continued)

The CLU may not power up properly the first time it is turned on. Instead of performing normally, the CLU indicators will flash. This behavior occurs when the CLU battery is not able to generate the voltage needed. Leaving the power switch in

DAY position for about a minute, then cycling power will

condition the battery to supply power to the CLU. The power may have to be cycled on and off several times before the battery is warm enough to begin normal operation.

Off Mode. Power switch is in the OFF position. In this mode,

no power is applied to the CLU. The daysight can be used for surveillance, target detection, and recognition. The NVS cannot be used and the gunner has no missile launch capability.

Day Mode. Power switch is in the DAY position. In this mode,

power is applied to the CLU. The day FOV can be used to acquire a target. The gunner has full missile launch capability.

Night Mode. Power switch is in the NIGHT position. In this

mode, NVS cooldown is initiated. NVS cooldown time is approximately 2.5 minutes. The gunner has full missile launch capability.

Test Mode. Power switch is placed in the TEST position,

then released. BIT can only be performed when a round is not attached to the CLU. When a round is attached, the TEST position is ignored. Results of BIT are displayed on the CLU display within about 20 seconds of initiation. If a failure is detected during BIT, the CLU BIT FAILURE 7 indicator will light.

(51)

JAVELIN OPTICAL SYSTEMS AND FIELDS OF VIEW

Javelin is equipped with three optical systems; two in the CLU (daysight and NVS) and one in the round (seeker). An optical system is a series of optical elements (lenses, mirrors, filters, etc.) that gather light at the system’s input and develop an image at its output. In this case, the output is to the gunner. The area of a scene that can be viewed at one time through an optical system is the FOV.

An optical system’s FOV is related to the system’s magnification. The wider the FOV’s coverage, the less magnification it has. The narrower the FOV's area of coverage, the greater magnification it has. Javelin has four FOVs. They include: day FOV, WFOV, NFOV, and seeker FOV. The daysight provides the day FOV. The Night Vision Sight provides WFOV and NFOV. The seeker, found in the missile, provides seeker FOV.

Daysight. The daysight is like a telescope. It provides day

FOV for the gunner. Day FOV is used when visibility is good. It is also used to engage a target when the gunner cannot wait the 2.5 minutes required for the NVS to cool down.

(52)

JAVELIN OPTICAL SYSTEMS AND FIELDS OF VIEW – (Continued)

Night Vision Sight. The NVS is an imaging infrared (IR)

system. It converts an infrared target into a visible target image. This allows the gunner to see during daytime and conditions of limited visibility. The NVS has two fields of view: WFOV and NFOV.

Wide Field of View. The WFOV provides the gunner with a

4x magnification of the target scene. With an area of coverage approximately 6° x 4°, WFOV covers a large or wide area compared to NFOV. This allows the gunner to scan a large general area to detect potential targets. However, the gunner will not be able to distinguish target detail. As a result, WFOV is used for surveillance and target detection.

(53)

Narrow Field Of View. The NFOV provides an infrared

image with 9x magnification of the target scene. With an area of coverage approximately 3° x 2°, NFOV covers a smaller, or narrower, area of the scene than WFOV. The gunner would have to move the CLU back-and-forth and up-and-down in NFOV to cover the same area as WFOV. The gunner only uses NFOV after locating a potential target. This lets the gunner see a potential target’s details more clearly so the gunner can determine whether or not it’s a target. Therefore, NFOV is used primarily to classify and recognize a target, but it can be used for battle assessment also.

(54)

Seeker Field Of View. The seeker FOV provides an infrared

image as seen through the missile with 9x magnification of the target scene. Images in seeker FOV are not as detailed due to the limitations of the optics of the seeker. This FOV is used to lock on to a target and engage it.

(55)

SEEKER OPERATION

Seeker Activation. The CLU must be attached to a round

before the seeker can be activated. Squeezing the seeker trigger when in DAY mode of NVS mode can activate the seeker. Once the gunner squeezes the seeker trigger, it initializes software download from the CLU to the missile. The seeker begins to cool down and the missile powers up, the 1 and < indicators will light up on the CLU display until the seeker is ready for use (10-15 seconds). The CLU display will change from either ., /, or 0 to 1. Track gates will appear and flash, the < indicator will go out and the 2 attack indicator will come on.

(56)

SEEKER OPERATION – (Continued)

Track Gate Adjustments. The gunner uses track gates to

lock the seeker onto the target. Track gates are adjusted using the GATE ADJ/CTRS & BRT switch. Track gate adjustments can only be done after seeker activation and prior to lock-on.

(57)

SEEKER OPERATION – (Continued)

Seeker Lock-On. After the track gates are adjusted around

the target, the gunner squeezes and holds the seeker trigger. Two things happen to indicate lock-on has occurred. The track gates stop flashing and solid crosshairs appear on the CLU display.

(58)

MISSILE OPERATION

Missile Attack Modes. The Javelin can kill a target at two

thousand meters. In addition, the missile has two gunner-selectable attack modes (top or direct). Each mode has its own peculiar flight path or "profile" for reaching the target.

Top Attack Mode. In top attack, the missile comes from

above the target to impact and detonate on top of the target. This capability allows you to attack a vehicle from the front, the rear or a flank position. Generally, armored vehicles have less protective armor on top. By striking the top of the vehicle, the missile penetrates the vehicle and still has enough explosive force remaining to do extensive damage inside the target vehicle. This mode greatly increases the probability of a kill.

Top attack is the default missile mode when the seeker is first activated. The exact profile of the missile during flight depends on range to the target and is determined automatically by the missile on-board software.

If the target is under a protective structure, using top attack may cause the missile to impact and detonate on the structure instead of the target. To avoid this, the missile can be programmed for direct attack.

(59)

MISSILE OPERATION – (Continued)

Direct Attack Mode. In the direct attack mode, the missile

impacts and detonates on the side of the vehicle. The direct attack mode flight allows the missile to reach a target that is under a protective structure at a maximum range of 2000 meters. To do this, the missile flies a more direct route from the gunner to the target vehicle. Direct attack can be selected only after the seeker is activated when the gunner pushes the ATTK SEL switch on the right handgrip. As in top attack, the exact profile of the missile flight path depends on the range to the target.
