KV-7 self-propelled gun project ("Object 227" - " Object 227") on the tank chassis KV. Two prototypes were made.
The first prototype KV-7 (U-13) was armed with one 76.2 mm cannon and a pair of 45 mm cannons.
The second prototype ( KV-7 (U-14)) was armed with a pair of 76.2 mm cannons. It was a modified first prototype.
The first prototype is sometimes referred to as KV-6, which is the prototype designation "Object 226" (" Object 226 ").

In November 1941 (11/1941), on the initiative of the design offices of ČKZ (ЧКЗ) in Chelyabinsk and UZTM (УЗТМ) in Sverdlovsk began work on the construction of a self-propelled gun on the chassis of a heavy tank of the KV-1 type under the leadership of Zh. J. Kotin (Ж.Я. Котина). Two variants of artillery armament were designed for the vehicle. The first variant, designated KV-7 (U-13), consisted of an initially unmounted armament consisting of a 76.2 mm F-34 gun (76.2mm пушка Ф34) and a pair of 45 mm guns of model 1932/34 (45mm пушки обр. 1932/34 гг) in a single lafette. The factory index of the prototype was U-13 (У-13). Later, the possibility of movement also in the horizontal direction was added
The first prototype was produced at UZTM as early as December 1941 (12/1941), and subsequently firing trials were carried out on the test bench. Final assembly of the machine was completed at the ČKZ plant in early 1942. It was the first heavy self-propelled gun produced in the USSR during the Great Patriotic War, but it was not introduced into the army's armament.
The self-propelled gun was intended as an artillery support vehicle for tank units with a large cadence. The self-propelled gun featured full armor cover for the crew. It was created by modifying the KV-1 tank, whose swivel turret was replaced by a fixed armoured superstructure with mounted armament. Other differences were a lower height and increased crew numbers.
The chassis design did not differ from the standard tank - there was an engine-gear compartment in the rear of the machine, a fighting compartment with armament in the middle part, and a driver's position in the front. The crew consisted of six persons. The driver-mechanic and the gunner-radarman to his left had positions at the front of the chassis. In the combat section to the left of the armament were the positions of the sighting officer and behind him the first loader, to the right of the armament the commander and behind him the second loader.
Six portholes, covered by armoured covers, served for observation of the battlefield. The driver had a glazed porthole in front, which was covered by an armoured plate with a slit. The driver and radio operator also had periscope instruments.
The crew embarked and disembarked through two circular hatches in the superstructure roof, with an emergency exit behind the driver's seat on the underside of the chassis.
Sighting of all three guns was provided by a single sight. The layout of the rifles allowed for aiming in a sector 15° wide (7.5° to either side) and aiming from -5° to 15°. Firing could be conducted by a volley from all three guns, a pair of guns, or separately. The whole rifle was aimed at, it was not possible to aim individual weapons separately. The telescopic sight TMFD7 (ТМФД7) was used for aiming. The weapon cadence was 12 shots per minute. Additional armament consisted of a pair of 7.62 mm machine guns DT (ДТ) - one located at the gunner-radar position, the other in the rear wall of the fighting compartment. There was also a third, free (backup) machine gun DT (ДТ), which could be placed on the armoured superstructure and used as an anti-aircraft gun if necessary.
The superstructure housed a total of 93 rounds of 76.2 mm calibre and 200 rounds of 45 mm calibre. There were 57 magazines for machine guns (3591 rounds).
The armour thickness was 30, 60 and 75 mm, with the armour sloped at a precisely calculated angle to increase armour protection. Screens with a thickness of 20 mm were used as additional armouring. The thickness of the frontal armour of the armour plate reached 100 mm.
The prototype KV-7 (U-13) subsequently served as the basis for the evolutionary successor, the prototype KV-7 (U-14).

V zdrojoch je uvedená informácia, že bola rozbehnutá výroba predsériových vozidiel v počtoch desiatok kusov korieb a nadstavieb. Po útlme programu KV-7 (U-13) bolo treba tieto vyrobené komponenty nejako využiť a preto vznikla iniciatíva na lafetáciu 152 mm húfnice ML-20 vzor 1937. Samohybný prostriedok mal niesť označenie U-18.
