▲

Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The AMX 13 F3 AM is a French tier 6 self-propelled gun.

At the end of the 1950s, engineers of Creusot-Loire developed the new vehicle on the shortened basis of the AMX 13. The vehicle featured a 155-mm gun. It was mass-produced from 1962 through 1997 with a total of 600 vehicles manufactured. The SPG is still in service in France, Argentina, Chile, Ecuador, Morocco, and other countries.

The AMX 13 F3 AM leads to the Lorraine 155 mle. 50.

Player Opinion

Pros and Cons

Pros:

- Good acceleration and top speed

- Low profile and good camouflage value

- Asymmetrical gun arc is helpful in niche situations

- Largest caliber and splash radius, highest penetration and damage for a Tier VI SPG

- Best shell velocity of all Tier VI SPG's

Cons:

- High dispersion while turning or moving

- Asymmetrical gun arc can be a bit tricky to utilize

- Absolutely no gun depression

- Long aim time

- Second worst DPM and worst reload speed of all Tier VI SPG's

Performance

The AMX 13 F3 AM is one of the most mobile Tier VI SPG's, having a good acceleration and top speed. To add to this the camouflage values of this artillery are very good thanks to its small size and low profile. These attributes make the AMX 13 a stealthy, easy-to-relocate SPG that can utilize its mobility to move to better firing lines quickly to get shots on tanks that think they are safe. This, combined with the highest alpha damage in tier of 700 makes it a threat to any tank it faces and can one-shot many lower-tier and a few same-tier tanks if the shell manages to penetrate.

Despite a long aim time and the longest reload at Tier VI, the AMX 13's fully-aimed accuracy remains quite good due to low dispersion, low shell trajectory/flight time, and a relatively high shell velocity — you shouldn't have many problems hitting your targets. The asymmetrical gun arc has a bit of a learning curve but for normal use the angle that you are given to shoot from is quite generous, and there is a fair margin for turning the gun without having to turn the hull. Make sure you're always angling your hull to the left a bit to maximize the use of your gun arc.

Unfortunately, despite its good accuracy and wide gun arc, it performs very poorly as a shotgunner. Its high bloom and lack of gun depression make shotgunning tanks tricky, relegating it to ambush tactics and relying on its first (and only) shot to kill the enemy. Position on the downslope of a hill to allow your gun to point farther down and increase your chances of a hit.

If you happen to own the 105 leFH18B2 you can plug most of your crew into it for use as a crew trainer, but you'll have to leave one of the loaders behind.

Historical Info

The AMX 13 F3 AM or Canon de 155 mm Mle F3 Automoteur (Cn-155-F3-Am) was a 155mm SPG developed in the early 1950's by the French Army to replace their aging American M41 Gorilla 155mm self-propelled guns. The Mk F3 is the smallest and lightest 155mm motorized gun carriage ever produced. Due to its size and low cost it has found considerable success in the export market. Constructed on a modified AMX-13 light tank chassis, the Mk F3 is novel, incorporating room inside for only two of the eight required crewmen (the others riding in support vehicles). This allowed the 155mm gun to be placed on a smaller and more mobile chassis than that employed by other armies, but also exposed the crew members to small arms fire and shell splinters.

Backround

AMX 13 F3 in a deployed position

In the early 1950's the French Army desired to replace their aging American M41 howitzers with an indigenous design, based on the AMX-13 light tank chassis. The result of these efforts was the Mk. F3 that entered production in the early 1960's. Its low cost and light weight made it a very popular weapon system on the export market. It was exported to a number of South American and Middle Eastern countries, and remained in production until the early 1980's, long after the French Army had themselves converted to the fully enclosed GCT 155mm self-propelled artillery system.

Design features

The Mk F3 is essentially a modified AMX-13 light tank chassis with the rear idler removed and the hull modified to accept a 155mm cannon and its recoil, elevating and traversing mechanisms, including two rear spades which reversed into the ground to give added stability when firing. The 155mm gun was designed by the Atelier de Construction de Tarbes (ATS), and the chassis by the Atelier de Construction Roanne (ARE). Integration of the gun with the chassis and all firing trials were undertaken by the Etablissement d'Etudes et de Fabrications d'Armement de Bourges (EFAB). Because the ARE was tooling up for production of the AMX-30 main battle tank, production of the whole AMX-13 tank family, including the F3 155mm self-propelled gun, was transferred to Mécanique Creusot-Loire.

The F3 fired the standard 155mm high-explosive projectile and is also capable of firing smoke, illumination and rocket-assisted rounds. The effective range is 20,050m with 43.75kg HE rounds. The hull of the Mk F3 is of all-welded steel armor measuring 10 to 20mm, providing the two occupants with some protection from small arms fire and shell splinters. The layout is conventional, with the driver's compartment at the front on the left, engine compartment to the right and the 155mm gun above at the rear. A splashboard is mounted at the front of the hull to stop water from rushing up the glacis plate when the vehicle is fording streams.

AMX 13 F3 designed to replace M41 in French army service

A replacement road wheel is often carried on the glacis plate. The driver has a single-piece hatch that opens to the left and is provided with three daylight periscopes, the center one of which is replaceable by an image intensification (or thermal) periscope for night driving. The commander is seated behind the driver and has a two-piece hatch that opens to either side. The commander is also provided with three daylight periscopes.

The torsion bar suspension consists of five single rubber-tyred road wheels with the drive sprocket at the front and the fifth roadwheel acting as the idler. There are three track-return rollers. The first and last road wheel stations have hydraulic shock-absorbers. The steel tracks can be fitted with rubber pads if required. Stowage containers are provided along each side of the upper part of the hull. Standard equipment includes a loudspeaker and a cable reel with 400m of cable.

Design flaws

AMX 13 F3, smallest 155mm SPG ever built

Weaknesses to the Mk F3 design included a lack of nuclear-biological-chemical (NBC) protection for its crew. It also could accommodate only two of the eight crew members needed to operate the weapons system. The remaining six crew members and 25 rounds of ammunition travel in support vehicles, normally AMX-VCI's. If necessary the additional crew members can travel on the upper deck of the vehicle, but in all cases the crew members must remain outside the vehicle and exposed to arms fire.

Production

A total of around 600 vehicles was produced until the late eighties, with the last 10 units delivered to Morocco as late as 1997. Besides the French Army the system was widely exported and used by the armies of Argentina, Chile, Ecuador, Morocco, Saudi Arabia, Peru, Venezuela, and Qatar.
