 missiles were fired. During the first test firing the system achieved a direct hit while moving at 20 mph (30 km/h). The second test firing, conducted at night while stationary, also achieved a direct hit. The third test firing, conducted while on the move and in the rain, did not achieve a direct hit, but did however, pass within the missile's kill range and the shot was scored as a tactical kill. All three test shots were conducted by operators who had never fired the missile before.

In 1987, the Army awarded the first production contract for 325 units. In 1989, the system began its Initial Operational Test and Evaluation (IOT&E) series of tests. The tests were conducted in two stages with Stage 1 consisting of acquisition and tracking trials at Fort Hunter Liggett

Description

The Avenger comes mainly in three types of configurations, the Basic, Slew-to-Cue, and the Up-Gun. The Basic configuration consists of a gyro-stabilized air defense turret mounted on a modified heavy Humvee. The turret has two Stinger missile launcher pods, each capable of firing up to 4 fire-and-forget
Fire-and-forget
Fire-and-forget is a third-generation method of missile guidance. The military uses the term for a type of missile which does not require further guidance after launch such as illumination of the target or wire guidance , and can hit its target without the launcher being in line-of-sight of the...

 tracks and messages to be passed to the fire unit to alert and cue the gunner.

The Slew-to-Cue (STC) subsystem, allows the commander or gunner to select a FAAD C3I reported target for engagement from a display on a Targeting Console developed from VT Miltope's Pony PCU. Once the target has been selected, the turret can be automatically slewed directly to the target with limited interaction by the gunner.

The Up-Gun Avenger was developed specifically for the 3rd Armored Cavalry Regiment for the Regiment's 2005 deployment to Iraq. The modification was designed to allow the Avenger to perform unit and asset defense on top of its air defense mission. The right missile pod was removed and the M3P .50 cal machine gun was moved to the pod’s former position. This allowed for the removal of the turret's cab safety limits which enabled the gun to be fired directly in front of the HMMWV. Eight of the unit's Avengers were modified to this configuration. With the 3rd ACR's redeployment from Iraq, the Up-Gun Avenger completed its role in Operation Iraqi Freedom and the Avengers have been scheduled to be converted back to STC systems.

Variants

Boeing/Shorts Starstreak Avenger

Boeing teamed with Shorts Brothers PLC to offer the Avenger system modified by replacing 1 Stinger pod with a pod of 4 Shorts Starstreak Hyper-velocity laser-guided missiles in the hopes of attracting a U.S. Army contract under the Forward Area Air Defense System Line-of-Sight Rear (FAADS-LOS-R) program. Test installation was carried out in mid-1990 and firing trials followed from mid-1991 in the U.K. Starstreak would compliment the Stinger by improving the overall systems ability to deal with low hovering helicopters which frequently do not provide enough contrast for lock-on by infrared guided missiles. Starstreak also has the ability to be used against un-armored and lightly armored ground vehicles.

Boeing/Matra Guardian

In the 1990s Boeing teamed with Matra of France to offer the Avenger modified by the substitution of standard triple launcher boxes for Matra Mistral missiles in place of the quadruple Stinger pods of the standard Avenger. One demonstrator vehicle was built in 1992 and test firings took place in France. The project was dropped around 1997.

Avengers in Iraq

Due to the lack of airborne threat in Iraq, and the pressing need for ground assets for combat roles such as convoy protection, the Avenger has been pressed into this role. The FLIR/laser rangefinder combined with the .50 cal machine gun has proven very effective, but is limited by no-fire zones, particularly to the front of the vehicle. A program was instituted to remove one of the missile pods and move the machine gun to that position to enable a 360° field of fire. This upgrade also increased the ammunition capacity to 650 rounds.

Avenger DEW

Another potential variant proposed by Boeing is an Avenger with a Directed Energy Weapon (DEW). Boeing has complete initial test of a 1 kilowatt laser mounted where the right missile pod would be. The M3P .50 cal has been replaced by the M242 Bushmaster

 as its close defense weapon.

Avenger Multi-Role Weapon System

Test firing demonstrations took place in 2004 of this variant modified by re-locating the M3P machine gun over the turret cab to allow a 360-degree field of fire, ready-use machine gun ammunition stowage increased to 600 rounds and the option to substitute launchers for 2 FGM-148 Javelin

Other Variants

Boeing have proposed that the Avenger PMS turret could be mounted on other vehicles such as the Unimog truck, BV-206 all-terrain vehicle, M113 APC, and M548 tracked cargo carrier as well as being used as a stationary ground mount on a pallet for defense of static targets.
