The AER9 is a military-grade Laser Rifle used by the Brotherhood of Steel and the Enclave in Fallout 3 instead of the Wattz 2000 Laser Rifle used in previous Fallout games. Talon Company mercenaries may also be armed with them. Its Pistol-sized counterpart is the AEP7 Laser Pistol.



The AER9 was not considered cutting-edge technology before the war, being an older model than the state-of-the-art AER 12, used in a handful of specialty units. The redeeming feature of the AER9 was its reliability - the focusing crystal array was housed in a titanium casing, rather than the gold alloys used in later models, which allowed it to withstand years of exposure to the environment without loss in array focus.

As with all energy weapons, the AER9 can suffer from poor performance if not properly maintained. The crystal arrays and non-mechanical components are delicate and if not properly serviced can lead to a loss of beam intensity, overheating, and energy regulation failure. Given that laser weapons were still in their infancy as regular military weapons, parts can be hard to come by in the wasteland. However, its lack of moving parts (aside from the MF cell holding latch and trigger mechanism) means it is resilient against extended use.

By nature of firing a beam projectile, its shots will instantly hit, negating any need to lead the shot.

A fully repaired Laser Rifle can fire 1086 bolts, about 46 full cells, before breaking.


In combat, the Laser Rifle is an exceptional weapon. It performs admirably at medium and long ranges where its accurate semi-automatic fire combined with its large ammo capacity makes short work of most opponents. However, its semi-automatic nature prevents it from being a viable close quarters combat weapon. As such, the Laser Rifle is a good weapon for traveling through the open wastelands where dispatching enemies at a distance is a frequent opportunity. Although its damage output is only comparable to the Hunting Rifle and lower than the Sniper Rifle, its rapid semi-automatic action, sizable magazine, minimum spread of 0 (meaning potentially perfect accuracy), extreme effective range, and exceptionally low AP cost allows the Laser Rifle to really stand out.

A deadly critical hit from this weapon, as with all other energy weapons, will not only kill enemies but also turn them into a pile of sparkling ashes, which can still be looted as normal. Note that the Brotherhood and the Enclave both use these rifles, however, Enclave Forces also field Plasma Rifles alongside the AER9. Even though the Plasma Rifle does twice as much damage, the Laser Rifle's capacity is twice as large.

If you explore Fort Independence, you will come across a terminal in the Weapon Research room near the Armory Room, which says the the AER9 will overheat after numerous shots and that it is only supposed to be able to fire 12 to 13 shots per Micro-Fusion cell when you can obviously shoot 24 (or 30 with the Wazer Wifle) lasers per Cell.

One very useful trait about this weapon is that, with a high enough Repair skill, you can repair them to 100%, giving them the sizable value of 999, caps. Meaning at 100 barter skill, you can usually sell one for around 890 caps to 950, depending on the vendor.


There are a number of Laser Rifles that can be found from an early level:

  • Laying next to a dead Brotherhood Initiate in the north office building off of Falls Church (the one without Initiate Pek).
  • On a shelf in the Overseer's Office of Vault 92
  • One in a cabinet in The Family's home. (Hard lock)
  • Can be discovered in a room next to some skeletons during the Stealing Independence quest.

These Laser Rifles aren't usually in the best shape and getting them repaired by merchants can be quite expensive.

Additionally, Enclave Soldiers typically have Laser and/or Plasma weapons equipped (usually at about 1/3 CND) so plenty of Laser Rifles can be found inside of the Enclave Headquarters at Raven Rock.


Variations of the AER9 exist in Fallout 3 and its add-ons:

  • Metal Blaster (The Pitt add-on) - This unique variant of the AER9 fires nine beams at once, using one Microfusion Cell similar to the Protectron's Gaze Laser Pistol. This feature, coupled with its remarkably high damage-per-shot makes it a devastating short to close-range weapon, though its effectiveness greatly diminishes at a range with the "shotgun effect". It can be obtained by bringing fifty Steel Ingots to Everett in The Pitt.

Behind the scenes

On the barrel, there is a warning: "Caution: laser radiation". It's also rated as a "Class 6" laser, which may be a subtle nod to the internationally used laser class rating system, which currently rates the strongest industrial lasers as "Class 5".

Interestingly, shooting a laser beam at the water produces surface waves. While in theory there should be little or no interaction between the photons of the beam and the (transparent) water, it seems likely that particles of dirt and other impurities are being heated, causing some of the water to flash into steam and produce waves.

Another interesting thing is that you should not be able to actually see the laser beam in front of the rifle. You should only see the place that it hits.

Something to notice while viewing this weapon in 3rd person, it has a huge hole in the bottom where the foregrip is. You can see through the gun. (Xbox 360)

Interestingly, as it appears relatively common in the Capital Wasteland, the weapon was not deployed during the Anchorage Reclamation. One way of explaining this inconsistency is that it was deployed elsewhere and had not reached a high enough production capacity to become widespread. (As a matter of fact, at the end of Operation: Anchorage when you encounter General Jingwei, some T-51B units are using laser rifles. Checking their inventories shows that they are, in fact, ordinary Laser Rifles, and were not reskinned or redone for Anchorage.)
