+The 12.7 mm LKk/42 uses the American 12.7x99 Browning cartridge, modernly called .50 BMG. This round was produced in Finland but with domestic projectile types during WWII. These consist of 3 types: AP, AP-T, and Incendiary. Projectile performance is more or less equal to their American counterparts, however the overall efficiency of the gun is limited due to the lack of any API or API-T rounds.
-In game the gun has access to 6 belts: Default, Universal, Ground Targets, Air targets, Tracers and Stealth.

-The 12.7 mm LKk/42 was a Finnish copy of the [[Akan m/39 (13.2 mm)|13.2 mm FN Browning aircraft machine gun]] from WWII. LKk/42 is an abbreviation for LentoKoneKivääri (an amalgamation of lentokone = aircraft, konekivääri = machine gun) m/42.

-The Finnish managed to get the plans for the gun via Sweden as war aid in the early '40s. The calibre was changed to 12.7 mm Browning and the weapon was used to upgrade old fighter aircraft such as Brewster Buffalos and Curtiss Hawk 75's in Finnish service during the later stages of the war.

 === Origin ===
-Like most modern nations prior to WWII, the Finnish wanted to adopt a heavy airborne weapon which could deal with the armoured full metal fighters and bombers entering service at the end of the 1930s. There were several weapons on the market designed for this specific purpose and one of those was the [[Akan m/39 (13.2 mm)|13.2 mm FN Browning aircraft machine gun]] by FN Herstal. The weapon had a high fire rate of ca 1100 rounds per minute and could fire high explosive projectiles. This was the weapon Finland wanted to buy.

The weapon had a high rate of fire at ca. 1,100 rounds per minute and could fire high explosive projectiles. This was the weapon Finland wanted to buy.
 Unfortunately, Finland was not alone in wanting to buy the gun and several countries stood in line to buy it. Things only got worse as the Winter War started in September 1939 which meant that a suitable replacement had to be found quickly. In the end, the Finnish had to adopt the [[M2 Browning (12.7 mm)|M2 Browning]] (export name Colt MG 53-2) as they ordered the Brewster Buffalo in December 1939.

 ==== Main use ====
-Besides upgrading old planes the Finnish also planned to use the 12.7 mm LKk/42 on several future aircraft. One of these was the VL Myrsky, a single-engine monoplane fighter with a mixed construction airframe and 1100 hp Twin Wasp engine. The Finnish had been working on the Myrsky since 1939, but because of the war they had not been able to acquire any engine for the aircraft. By 1943 the Finnish had finally been able to acquire enough engines to start production of the Myrsky. As the Myrsky was severely outdated as a fighter by 1943 it was decided to give it extremely heavy hitting armament so it could at least take down slow attack aircraft such as the [[IL-2 (Family)|IL-2 Sturmovik]]. The Myrsky ended up receiving four 12.7 mm LKk/42 machine guns in the nose, all shooting synchronized through the propeller. While this lowered the rate of fire of the 12.7 mm LKk/42 from ca 1100 rounds per minute to around 750 rounds per minute it was still heavy-hitting as all 4 machine guns sat next to each other and fired within a 1-metre span. This concentrated the fire and turned anything it hit into Swiss cheese within seconds. In the end however, the Myrsky only ever destroyed 2 aircraft (damaged 2 fighters which crashed on landing) and it was almost immediately relegated to reconnaissance and ground attack missions. This only got worse with time as its mixed construction did not fare well in the Finnish climate.
