P39/10

The P39/10 is a main battle tank developed by Bloodia. Derivatives and variants continue to serve as the primary battle tank of Bloodia.

Development
Development of P39 began after the failed joint-program of Kus, Kadolha and Bloodia for a new MBT to counter the new Drevarian not!T-62 and not!T-64. The Bloodian military dropped the joint program in 1972 and began fresh with a new design to replace ageing and outdated P38 main battle tanks. The project requirements was improved armor to defeat the threat of new 115mm and 125mm tank guns. The two main prototypes would be finished by 1976, the Bloodian Land Forces would combine both prototypes to become the P39, fitted with an 105mm rifled cannon due to the slow progress of the new 120mm smoothbore cannon's ammunition and due to the high stocks of 105mm ammunition and the development of new sabot using depleted uranium rounds.

The P310's was developed as an upgrade to the P39 fitted with a new cannon and depleted uranium armor.

Production history
Production began in 1979 with the overall production of 3,273 P39s between 1979 and 1985. Starting in 1986 production was started for the newly improved P310 with the new 120mm smoothbore cannon, between 1986 and 1992 5,000 P3910s were produced with several P39's being refitted into P310s.

Service History
The P39 entered service in 1979 and later the P310 entered service in 1985.

Combat history
TBD

Armament
The P39's main gun is the Bloodian A98 105mm rifled gun, it is a modified gun from the P38 capable of firing depleted uranium armour-piercing fin-stabilised discarding sabot (APFSDS), high-explosive anti-tank (HEAT-FS), and high explosive fragmentation (HE-FRAG) ammunition. This tank gun was later replaced in the P310 with A99 120mm smoothbore tank gun which is capable of firing newer depleted uranium and tungsten armour-piercing fin-stabilised discarding sabot (APFSDS), high-explosive anti-tank (HEAT-FS), and high explosive fragmentation (HE-FRAG) ammunition.

Cz-91's secondary armament is fitted with either a 12x99mm machine gun or 20mm anti-air canon, depending on role within the ground forces) both of which are remotely controlled inside the tank and has a 7.62mm coaxial machine gun.

Mobility
Fitted with a multi-fuel gas-turbine engine for high mobility and adaptability. The engine is capable of taking diesel, petrol, marine diesel and jet fuel.

Protection
The P39 is fitted with ceramic blocks, metal plates and open space and NERA.
