The '''105 mm Modèle F1''' (or CN-105-F1) is a 105 mm rifled tank gun used by the AMX-30 and its variants. The gun is made from steel with a magnesium thermal sleeve to protect against damage such as bending. One of the unique features of the gun was the ability to shoot the '''Obus à Charge Creuse de 105 mm Modèle F1''' or OCC for short.

Description

The 105 mm Modèle F1 (or CN-105-F1) is a 105 mm rifled tank gun used by the AMX-30 and its variants. The gun is made from steel with a magnesium thermal sleeve to protect against damage such as bending. One of the unique features of the gun was the ability to shoot the Obus à Charge Creuse de 105 mm Modèle F1 or OCC for short.

Vehicles equipped with this weapon

General info

The Modèle F1 is fitted with a semi-automatic vertical sliding wedge breechblock but it is lacking a muzzle brake. As opposed to the British L7A1, the F1 cannon uses a compressed air scavenging system instead of a bore evacuator. The recoil mechanism uses two symmetrically opposed hydraulic brake cylinders with a single hydropneumatic recuperator cylinder.

Available ammunition

  • OCC 105 F1

The OCC projectile is the default HEAT round the user starts out with. It consists of two parts, the outer shell with a suspended inner shell connected by ball bearings. This allowed the HEAT round to be spin stabilized unlike other modern HEAT rounds which are fin stabilized. It weighs 10.95 kg and the warhead contains 780 g of RDX. Its speed is 1000 m/s with the penetration force of up to 400 mm.

  • OE 105 F1 Mle.60

The OE 105 projectile is a default HE round the user stats out with. It consists of a steel body with an explosive filling of the TNT type. There is a sensitive impact fuse at the end of the projectile which detonates upon contact with any surface. The projectile weighs 12.1 kg and the explosive mass is 2 kg worth of TNT. Its speed is 700 m/s with the penetration force of 25 mm.

  • OFPH 105 F1

The OFPH 105 projectile is a smoke round that upon impact, creates a smoke screen for 5 seconds. The smoke screen itself lasts 25 seconds and is 20 m big. It weighs 11.4 kg and moves at the speed of 700 m/s.

  • OFL 105 F1

The OFL 105 projectile is an APFSDS round that relies on kinetic energy and spalling to damage enemy vehicles. It weighs 3.45 kg but drops to 1.6 kg in-flight due to the SABOT discarding. It moves at the speed of 1525 m/s with the penetration force of up to 361 mm.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

Cons:

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/ History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the article about the variant of the cannon/machine gun;
  • references to approximate analogues by other nations and research trees.

  • topic on the official game forum;
  • encyclopedia page on the weapon;
  • other literature.
