ARMAMENT EQUIPMENT.

DEFENSIVE ARMAMENT.

Defensive armament consists of either two M-16 or AR-15 rifles. On aircraft O-2, defensive armament is located in mounts on the left cabin sidewall. The rifle mounts are located over each center side window in aircraft 8 .

OFFENSIVE ARMAMENT. 0

Offensive armament consists of two armament pylons on the undersurface of each wing, a non-computing optical gunsight directly in front of the pilot on the instrument panel glare shield, an armament control panel located on top of the instrument panel to the right of the gunsight, a trigger button on the pilot's control wheel, and provisions for a strike or recon- naissance camera in the cabin floor to the right of the pilot adjacent to the cabin entry door. The armament pylons provide for the attachment of various configurations of the following offensive stores:

1. SUU-11A 7.62mm MinigunPod.
2. SUU-14/A Bomblet Dispenser (7 Tube).
3. MA-2/ A Rocket Launcher (2 Tube).
4. LAU-59/A Rocket Launcher (7 Tube).

ARMAMENT CONTROL SYSTEM.

The offensive armament controls are located on the instrument panel (figure 1-3), armament control panel (figure 4-12), and on the underwing pylons (figure 4-14). Electrical power for the armament control system is provided from the primary bus bar.

Armament Master Switch.

A guarded armament master switch (4, figure 4-12) located in the center of the armament control panel, is used to control armament operation. The switch is marked MASTER and has two positions, ON and OFF. The armament master switch, when placed in the ON position, activates the armament circuits.

Gun Charging Switch.

The gun charging switch (1, figure 4-12) is located at the left extremity of the armament control panel and is marked CHARGE and OFF. When the charging switch is in the CHARGE position, aircraft electrical power is provided to the battery of the SUU- 11A Minigun Pod and furnishes battery charging voltage. The gun charging switch should be placed in the CHARGE position as soon as after take-off clean- up operations are completed to assure an adequate gun pod battery charge.

Fire/Drop Switch.

Four fire/drop switches (2, figure 4-12}, one for each wing pylon, are provided on the armament con- trol panel. The wing (RIGHT or LEFT} and pylon station on the wing (INBD or OUTBD} is marked adjacent to each switch. Each fire/drop switch is a three-position switch and each switch detent is label- ed. The detent positions are FIRE, OFF, and DROP. The position of the switch will vary in accordance with the ordnance carried. When the switch is in the DROP position and the trigger button depressed, voltage is applied to open the pylon shackles and thus drop the selected store. With the switch in the FIRE position and the trigger button depressed, the voltage is utilized to fire the minigun or launch rockets.

Arming Switch.

Four arming switches (3, figure 4-12) one for each wing pylon, are located on the armament control panel. The wing (RIGHT or LEFT) and pylon station on the wing (INBD or OUTBD) is marked adjacent to each switch. Each arming switch is a three-position switch and each switch detent is labeled. The switch detents are NOSE, NOSE & TAIL, and OFF. The detent position selected will vary depending upon the store carried on the affected pylon. The primary function of the arming switches is to provide locking voltage to the arming lanyard shackles in order that whenever bombs are dropped, the arming lanyards (nose or nose and tail) will be retained in the shack- les allowing the bomb to fuse after separation from the pylon.

Armament Panel Light Dimming Switch.

The light dimming switch is located at the right extremity of the armament control panel and is marked LIGHTS DIM (5, figure 4-12). Rotation of the knob will produce a corresponding increase or de- crease in armament control panel illumination.

Salvo Switch.

The guarded emergency salvo switch (6, figure 4-12] is located on the pilot's forward instrument panel directly above the altimeter and is marked SALVO on the red switch cover. The salvo switch is a two- position switch and is always in the OFF detent. When the switch guard is raised and the switch is placed in the DROP detent, all external stores are released unarmed regardless of the selector switch settings on the armament control panel.

The trigger button (1, figure 1-13) is located on the left handle of the pilot's control wheel. When the trigger button is depressed, firing voltage is transmitted to the selected store which is released or fired.
