What type of guidance section does the APKWS have and what is its nomenclature?

Semi-Active laser (SAL) guidance section (WGU-59/B)

Does the APKWS have any external electronic features?

No

How many wings does the APKWS have and when are they deployed?

It has 4 wings and its deployed after the thermal battery is activated upon rocket motor firing.

What does CAS stand for and what does it do?

Control Actuator System. It positions the flaperons in accordance with the commands provided by the autopilot

What does IMU stand for and what does it do?

Inertial measurement unit. It senses the APKWS II pitch, roll, and yaw and transmits that information to the autopilot

What does the autopilot do?

The autopilot uses the IMU and seeker data to calculate required wing positions, which are sent to the CAS which moves the flaperons to guide the target.

Where are the laser seeker optics located and what doe they do?

They are located on the forward edge of each of the four wings and receive laser energy reflected from the target. The laser energy is transmitted via fiber optics to the seeker electronics which determines the target angle.

The seeker optics are "___________" (not gimbaled) and provide constant field of view in excess of ____ degrees

Strapped down; 28

What does LSA stand for and what do they do?

Laser Switch Assemblies. These are dials attached to the guidance section that provide various laser coding options.

How are the LSA's read on the APKWS II

They are read facing aft, left to right, and a black line adjacent to the aft edge of the dial indicates the number selected on each LSA.

For the first (left most facing aft) LSA, which colored background turns the guidance countermeasures ON?

The light colored background with the black numbers.

Should we use the guidance section countermeasures?

No, because it has not been tested

What is the ETBI and why is it important?

The electronic thermal battery indicator which activates the capability for the thermal battery to be initiated upon firing. It aligns the explosive train used to initiate the battery. It's a manual switch on the outside of the missile which must be turned on or else the APKWS won't have guidance capabilities (it will fire like a regular 2.75" rocket).

Describe the flight path/times for an APKWS

1. Rocket fires

2. ETBI fully powered by 0.3 seconds

3. Wings deploy from 0.4 to 0.5 seconds

4. IMU begins initialization and comes online by 0.7 seconds

5. Guidance section attempts to acquire laser energy at 0.85 seconds

6. De-roll maneuver (change in flight path to stabilize the flight plath) complete by 1.1 seconds

7. After De-roll, system begins guidance

What happens if the laser energy isn't detected during flight?

The missile will enter altitude hold until it contacts the ground

What happens when the seeker acquires laser energy?

It enters Proportional Navigation Mode and attempts to hold ILOS (inertial line of sight) angle to the target, placing the APKWS on a collision course with the target regardless of winds or target motion.

What is the maximum time of flight and distance observed in tests of an APKWS in altitude hold mode

1 minute and 9 km

What is the release envelope of the APKWS?

1.5 to 5 km

Optimum employment range? Why?

3 to 4 km; It allows for the maximum error at those ranges of +/- 10 degrees azimuth and +/- 5 degrees elevation /

What must you select on the NARCARDS to get the APKWS rocket reticle

GUN PD

HUD Rules of Thumb

If you are outside 2500 m, below 500 ft HAT, or hovering, always use the 3 degree cue.

If you are inside 2500 m and:

Above 1200 feet HAT - use 1 degree

How many degrees should the firing pilot lead a moving target laterally?

3 degrees

Firing against moving targets is affective against a moving target moving _____ mph with a ______ degree track crossing angel

40 mph; 90 degree

At the maximum range of 5 km, the APKWS requires ________ feet of cloud clearance

1000

What is the recommended means for employing the desired laser code?

Enter the laser code into the H code and setting TSU/GUNS. Ensure LOW track rate is selected to reduce spot jitter

What will you see in the HUD when the laser is fired?

The pipper will turn into an X and you adjust the reticle on the X based on rules of thumb

M282?

HE-incendiary penetrator warhead.

How many switch assemblies does the WGU-58/B contain?

4 Laser Switch Assemblies (LSA) that provide various code options.

The first LSA switch is identified with black and white background, what is each position used for?

The black position is the countermeasure off setting and the white position is the countermeasure on setting.

APKWS Warhead, Weapon-to-Target Match

M282 is a penetrator warhead only to be used with APKWS and not in an unguided role. With the M282 warhead, APKWS is truly an effective weapon-to-target match for lightly armored vehicles (i.e. APCs) vice with the M151 or Mk152 warheads which are HE-FRAG.
