406-mm gun 2A3.
In 1954, the Soviet Union embarked on the creation of a self-propelled 406-mm gun of special facilities for the destruction of conventional and nuclear missiles major military and industrial targets of the enemy, over a distance of over 25 km. The artillery system design stage in order to privacy was designated "condenser-2P" and later she was awarded the Department of Defense Index 2A3. The gun was developed in conjunction with a self-propelled mortar 2B1 "Oka" (more on that later), according to the decision of the Council of Ministers on April 18, 1955.
Special vosmikatkovaya heavy self-propelled undercarriage - "Object 271" - going from components and assemblies of the T-10M, which was taken as virtually unchanged powerplant. The tremendous power of the recoil when firing the gun partially quenched sink to the ground sloths, and hydraulic shock absorbers. Artillery units, designated SM-54, with the mechanisms of induction and loading been developing CDB-34 under the direction of II Ivanov.
A prototype self-propelled guns 2A3 going at the Kirov plant and entered the test in early 1957. Shooting at a central artillery range near Leningrad. In the vertical plane with a weapon suggests hydraulically, horizontal - by turning the entire system (for the tangent rotation mechanism has been linked with a special electric motor).
Tests revealed a lot of design flaws artillery system (rollback self-propelled several meters back injury sloths in the management of fire simulators nuclear missiles, destroying equipment and disruption to the transmission mounting), but after each shot the materiel installation was studied and measures were taken to eliminate bugs or weaknesses designs .
Total were built four 406-mm self-propelled guns 2AZ, shown in 1957 at a military parade in Moscow. In connection with the advent of missile complexes in the series, they were not issued.

420-mm mortar 2B1 "Oka»
Self-propelled mortar 2B1 "Oka" was developed in the mid-50s in two design bureaus: Kolomenskoye artillery units engaged in SLE engineering and chassis "Object 273" - CB Kirov plant in Leningrad. 420-mm mortar shells intended for firing nuclear warheads weighing 750 kg to a distance of 45 km.
Weight self-propelled exceed 55 tons, and the length of the smooth trunk was nearly 20 meters. The power plant of heavy machine was borrowed from the T-10. Recoil device in the mortar was not available, so the shot he rolled back on the tracks a few meters. Because of the complexity of loading feathered mines breech guns does not exceed the rate of 1 shot in 5 minutes. In the stowed position, self-propelled mortar managed only a driver - the rest of the payment was transported by truck or armored personnel carrier.
Total Kirov factory was built four self-propelled 2B1. November 7, 1957 at a military parade in Moscow, "Oka" was first demonstrated to the international community, together with the 406-mm self-propelled gun on the same chassis. Demonstration of these huge guns created a furor among foreign journalists and local inhabitants.
Some foreign experts have suggested that shown in Red Square gun mount - just a sham, designed for deterrent effect. They were far from the truth. During the tests by firing mortar conventional ammunition are not kept sloths, frustrated with the transmission mounting, there is another failure.
Completion mortar lasted until 1960, when the Council of Ministers issued a decree on the termination of work on the "Oka" and SM-54 gun. The main reason for this was the emergence of tactical rockets at a light tracked chassis with better maneuverability.
And the last Komrad. I have everything.
