Already in the late 30s of last century, the pace of development and the increased ability of anti-tank artillery tank builders forced engineers to find methods to increase armor protection. Adopted on arms 37 mm anti-tank gun 1K standard 30-year, (similar to the German 3.7 cm Pak gun PT 35/36) armor-piercing projectile 53-B-160, just punched armored leaf width up to 30 mm with a distance of 300 meters with a head angle of 60 °, armor penetration characteristics Pak 35/36 were slightly higher, it meant that she could hit at least some tank, located at the time in service of the Red Army Tank-Automotive parts. How to clear the Red Army tank fleet of the period consisted in the main of light tanks series of BT and T-26 of different years of release, which was bulletproof armor, a width of 13-20 mm, it was already clear enough for tank maintenance. Taking into account that the army of possible enemies possessed machines with protivosnaryadnym reservations, required machine more thick armor and with at least the same as the T-26 WT or sliding properties. One of the first projects of the tank with protivosnaryadnym book, was a project engineer T-111 S. Ginsburg, some sources refer to it as the T-46-5, but this is not correct, almost everything that is on the design of the chassis and hulls, it is other project, which was aimed at improving and increasing the body armor being developed at the time of the T-46 to replace the technical level outdated T-26, although certainly they look like from the outside.

In February, 1936 S. Ginsburg offers for consideration in the Red Army ABTU own first draft machines protivosnaryadnym booking "tank SP "in it, he planned increment armor up to 50 mm with the installation of armor plates under a huge angle. Unfortunately, apart from the memorandum, more information about this tank is not preserved. Taking into account the experience of the creation of the T-46, the beginning of 1937 S. Ginsburg begins to work on the project T-111 or else its title "object-111", but being at the time under investigation, vsepolnotsenno work he could not, only in 1938 the work resumed. The first prototype of the machine was made in April 1938. The hulls of the tank was built from hardened, rolled armor plate width of 20-60 mm, electric welding method has been innovation in tank since then. The actual weight of the machine due to significant growth in the thickness of armor were much higher than the calculated and totaled 32 tons, because the unit, diesel MT-5 engine with 300 hp, initially provided for installation on the tank, no longer fit, needed a more powerful engine. In the end, it was decided to set the DMT-8, but he was still "raw" it needed serious revision. Cast tower radial rotation, located on top of the housing on the traditional pattern, just had protivosnaryadnoe booking is 60 mm. Arms of the T-111, consisted of 45 mm cannon and three 7.62 mm armor-29 machine-guns, one mounted in the frontal armor plate, the second in the tower paired with a weapon, third was located at the rear of the tower in a ball bearing. Later on the course gun S. Ginsburg refused.

Chassis machine is a 6 semi-detached on two rollers filled with torsion bar suspension, 3 idlers front drive and rear guide wheels on the board. It is also necessary to emphasize that in order to reduce the surface pressure on the ground, was significantly increased, up to 500 mm Track shoe width. The crew consisted of three persons, the commander, driver and loader. In addition to the rest of the tank was installed radio, placed in the bow of the hulls near the driver's seat, to the right. Coming out of the industrial doors tank was immediately submitted to the troop tests, where the T-111 has shown good enough fighting and driving characteristics. Armor machines withstand direct hit 37 and 45 mm armor piercing projectiles patency and maneuverability tanks were generally the same as the T-46. But installed on the tank 45 mm tank gun 20K standard 1932/38 year could well hit most of the light tanks, but was not quite applicable to effectively tackle the medium tanks of the enemy. Setting a massive guns, such as the PS-3 or A-10 is not probable in view of their large size compared to 20K. Lock and also the newest, more capacious towers due to excess weight machines was inappropriate. Still, the Red Army ABTU factory number 185 was ordered to early 1939, to make a small series of T-111, for wider military trials, but the appointed time engine DMT has not been upgraded in the coming machine was recognized unpromising and manufacture of customized from the party, it was decided to abandon. But the implementation of the developments of the project engineer S. Ginsburg, T-111, we can build in the T-126 Joint Venture, located in the tank museum in Kubinka.
