The T-67 is a Stasnovan main battle tank introduced in the early 1960s. It was a more advanced alternative to the T-62: the T-67 served tank divisions, while the T-62 and T-55/T-54 supported infantry in motor rifle divisions. The T-67 formed the basis of many newer Stasnovan main battle tanks.
Development
The ever growing threat of the Federal Republic of Roski to the east, and the introduction of advanced variants of the Roskian main battle tank, the RT-1952 Stankić, drove the Stasnovan government to issue an order to its design bureaus to design and build a new, more advanced tank, as the Stasnovan T-54/55s and T-62s of the time were mostly outclassed by their counterparts. The T-67 was conceived in Tormavkovo, Krasnaya Socialist Republic, in 1964, as the next-generation main battle tank by Anton A. Mozhaev, the famous Stasnovan tank designer, whose name was later given to the Military Design Bureau he headed.
In 1965, the first prototype, called Object 1164 rolled out of the factory, and testing began immedeately. Another prototype, the Object 1164M, that fixed the original's drawbacks, and replaced the old 115 mm gun with a new 125 mm one, was built in 1966, and the first pre-production models entering field testing two months later. In late January 1967, the tank entered service as the T-67.
Service History
First Rekovian War
Agualados-Csoportsag War
During the Agualados-Csoportsag War in 2017, the KT-67S2A Variant faced Csoportsagi PcKTr-36 Caracals and PcKTr-43 Leopárds, as well as Grozyar PcKTr-69 Jaguars the T-67 performed well against the early PcKTr-36SF variants, but was heavily outclassed by the far newer and more advanced PcKTr-43S, and to date in the conflict, after seventy encounters between PcKTr-69SF Jaguar II variants and T-67, not a single Jaguar has been destroyed, with three examples being lightly damaged.
Design
Armament
The T-67 had a rather revolutionary trait for its time, the use of an autoloader in place of a human loader. The benefits of the autoloader were that only 3 crew members could operate the tank, while also decreasing the vehicle's silloute drastically. Plus, while a human loader could undeperform because of pressure under combat, the autoloader would be reliable, barring mechanical problems. The autoloader can load the gun in 6-8 seconds.
The T-67 is equipped with a 4A63 series gun, though it is replaced in later variants with more advanced weapons. The weapon can fire regural APFSDS, HE, HEAT and other types of shells. Variants from the T-67 and onwards (that are equipped with UTP-74 or UTP-94 guns) are also able to fire anti-tank guided missiles through the main gun. The T-67 is also equipped with a co-axial PKMT 7,62 mm MMG and an anti-aircraft NSVT 12,7 mm HMG.
Mobility
The original T-67As were powered by an E-750, 750 hp 6-cylinder diesel engine, while later variants are equipped with more powerful models of the series. Notably, the T-67U variant of the MBT, was equipped with a TG-1000, 1000 hp gas turbine engine. However, problems with said engine resulted in it being replaced by a 1100 hp 12-cylinder diesel engine in the latest T-67UM.
Protection
In another unique characteristic for its era, the T-67 was the first tank in the region of Atlas to use composite armor, instead of regural RHA plating. The T-67's armor, also called "K-Armor" consisted of an aluminium alloy layer between two high strength steel layers. The composite armour allowed for a low-weight, that helped the T-67 maintain excellent mobility.
Later variants, starting from the T-67B Obr. 1980, were equipped with Mech-1 ERA bricks, that were first mounted on the T-74B. The ERA bricks increased protection primarily against HEAT type weapons, however, late-production variants featured heavy ERA like the Mech-5 or the more advanced Zashchita-1, that also helped defeat modern kinetic energy penetrators.
Export
Variants
- Object 1164: Pototype version with UTP-51 115 mm smoothbore gun
- T-67A: Original SRA version that entered service in 1967.
- T-67B: Upgraded version of the T-67A launched in 1976. It is fitted with redesigned armour, a better engine (E-880, 880 hp), a new gun 4A76 and the option to launch ATGMs through the gun. An advanced T-67B variant that has been retrofitted with Mech-1 ERA bricks is called T-67B Obr. 1980.
- T-67BV: Upgrade launched in 1985. The upgrade featured a modified gun 4A76M with improved stabiliser for the gun and fire controls, an independent sight for the gunner with a thermal camera mode, and a laser receiver warning system. It was the first of the series to come with ERA bricks as standard issue.
- T-67U: Modernization program launched in 1992. Incorporating more modern and effective composite armor similar to that on the T-74M2, a new fire control system, new ballistic computer, and a 1000 hp diesel engine. Late production models were also equiped with Mech-5 ERA.
- T-67UM: Heavy modernization program launched in 2007 very similar to the T-74M3. It is upgraded with new fire control system including an improved gunner's thermal sight, "Tryuk" camouflage kit, new 125 mm 4A96 main gun with muzzle reference system and new "Zashchita-1" next generation ERA. This variant also features the Stena Soft-Kill Active Protection System. Only 200 tanks were modernised to this standard before the type was withdrawn from service.

It also had downgraded fire control systems and lacks the ability to fire ATGMs through its main gun.
- T-67S2: Export version of the T-67BV offered since 1988. Like other S versions, the gun, coaxial MMG and HMG can be changed. This variant features downgraded fire controls and stabiliser of the main gun, as well as reduced capability to mount ERA blocks.
