BTR-50PK
GBTU developed tactical and technical requirements provided for the development of two combat vehicles - light amphibious tanks and armored vehicles created on its base with a maximum harmonization. designing armored, received the designation "Object 750", Leningrad Institute engaged 100 in parallel with the PT-76 ("Object 740"), but with a slight delay. The lag was due to the fact, that a large number of design solutions, such as water jets, They were tested on the PT-76. Successful testing of the tank became the basis of what the designers were sure, armored personnel carrier that will be no less successful.
BTR-50PUM
When creating armored special difficulties have been associated with the development of the loading device, which is necessary for transportation, on heavy weapons including machine guns, and divisional GAZ-69. Two variants of the loading device was proposed: winch having a drive from the main motor for the loading of a folding cargo ramps; crane installation has electric. The latter option is rejected, observed because excessive structural and operational complexity.
The first prototype of an armored personnel carrier manufactured in April 1950 city, In July his factory testing, which included a run on 1,5 thousand. km. During one of the tests, which was associated with a test load capacity afloat, held in an abandoned quarry, nearly had an accident. After the first heat load with 2000 kg (corresponds to the technical project), and inspection, which showed the absence of water and the condition of the machine, Test leader has decided to repeat the swim with the extra load. To this end, almost all the participants - 20 man - climbed onto an armored vehicle. The car entered the water and the beginning of the movement, but in the middle of the pond, she began to sink into the water.

Avoid casualties has allowed the, that the depth of the pit was small and people, who were on the roof of the engine compartment, We are standing in water only foot. We got onto the roof and testers, sitting on the ground crew. After the car pulled to the shore, It revealed, that during the hasty preparations for the re-swim the mechanics were not put in place some of the bolts and lower hatches drain plugs. This "experience" was the reason that the attention to the preparation of the testing machine and raised such annoying episodes are not repeated.
In another design bureau under the guidance of AF. Kravtseva, simultaneously with the development of the "object 750", on the basis of a floating tank K-90 created a floating armored vehicle K-78. The ON № 2 in summer 1950 g. fabricated prototype.
Afloat BTR-50 moved by a pump-jet hydrojet
In a combat vehicle having a mass 10760 kg had an open-topped enclosure, welded from 15 mm of rolled armor plates. The armored personnel carrier were placed 2 crew member, 22 paratrooper. Embarkation / disembarkation infantry performed over the stern and sides Armament body - 7.62 mm machine gun SG-43 - was set to troop compartment in front of the left side bracket. Gun ammunition consisted of 1000 rounds. Chassis, transmission, navigable engine and propulsor were the same, like K-90 tank. When driving on the highway top speed of 34,3 kilometers per hour (stock moves - from 180 to 200 km), afloat - 9,7 kilometers per hour (power reserve - 80 km). This armored personnel carrier could be a competitor of the object 750, but the tank K-90 by the end of summer 1950 g. lost comparative tests with the "object 740", in this connection on the K-78 work was stopped.
At the same time CHKZ was made two copies of "Object 750" (in machines take into account the results of factory tests) and in August 1950 g. they were brought to their state. test, conducted with 4 by 29 September district g. Brovary, Kyiv region. program, approved the first deputy. Minister of War, Marshal Sokolovsky and the Minister of Transport Engineering Maksarev. Spend their commission, considered, that APC could not stand the test mileage warranty. therefore, in accordance with the decree of the USSR 31 December 1950 city, VNII 100, CHKZ Mintransmash and were required to make to the 01.05. 1951 two APCs with disadvantages and present them to the state commission.
BTR-50PU
New armored vehicles were manufactured by July, and from state testing took place in August. The August tests were found to be successful. On the basic parameters of the APC corresponded tactical-technical task, and by some measures, as the PT-76, superior to them. Three more cars, manufactured by August 1952 city, They were intended for military trials, held in September – October of the same year. During the tests, at the initiative of the designers, outside the program requirements, held shooting afloat and on land of 57-millimeter gun ZIS-2 and 85-mm D-44 (on the tactical and technical requirements provided for only their transportation). firing tests were successful, in undercarriage damage has occurred. Buoyancy is sufficient for firing without sinking or capsizing, that only confirms the exceptional quality of amphibious armored personnel carrier. However, the nominal installation DShK not stand the test program. Provided deficiencies state commission recommended that the APC to the adoption CA. Resolution of the USSR number of 175-89ss 30.01.1954 armored – an object 750 have adopted. The car was given the designation BTR-50P.
The manufacturer of the new machine, as in the case of the PT-76, It was determined STZ, which is quite logical. According to the decree of the Council of Ministers of the Stalingrad Tractor Works was obliged to 1954 g. to produce the first batch consisting of APCs 10 machines. AT 1955 g. It began mass production of the BTR-50P.
Serbian modernization of the BTR-50S
It should be noted, that production machines, Unlike prototypes, organic weapons was SGMB caliber machine gun 7,62 mm - turret machine gun mounted on the hatch of the ANC commander on arms was not adopted. At the same place 1956 he was placed another heavy machine gun - caliber KPVT 14,5 mm bronespinkoy, Tourette's. His ammunition consisted of 800 rounds. Elevation - + 85 °. But the car object 750m, which received the designation BTR-50 Pa, also adopted a.
Another two armored personnel carriers have remained prototypes. They were created on the basis of the BTR-50P in 1955 year. It is a question of self-propelled anti-aircraft installations ZTPU-2 and 4-ZTPU (These machines are sometimes referred to as APC-50P2 and BTR-50P4). Essentially ZTPU-2 was a BTR-50P troop compartment in which is installed cabinet having a frustoconical, consisting of two annular zones, connected by four studs arranged symmetrically. The lower belt fastened to the supports with bolts tables. Support to the bottom of the housing are welded. The upper belt was welded base bottom product machine gun. To increase the stability of the tables during the firing of its pillars with the upper front hull plates were connected removable spacers. The angle of vertical guidance guns KPVT – of -3 ° 20′ to + 91 °. Guidance manual drive mechanism has. Maximum speed guidance: Horizontal 46 ° 30′ sec., Vertical 37 ° 20′ in seconds. To the dictates of the fire at aerial targets used collimator sight VP-4, on the ground - telescopic OP 1-14. ammunition guns 1280 rounds. rate - 484 shots per minute. Installation serves one gunner and two loaders.

Machine ZTPU-2 provide effective destruction of airborne targets, flying at a speed of up to 600 kilometers per hour at an altitude of 500 to 1000 m. Horizontal range of effective fire 2 thousand. Metro.
From ZTPU 2 ZTPU-4 differed mainly the number of machine guns KPVT, which is now four. This required to strengthen and increase the pedestal ammunition. The effectiveness of fire rose, other features remain the same.
Series production of the most mass modification of armored personnel carriers - BTR-50PK (750PK object) It started in 1958 year. Its main difference from the basic version had a roof over the troop compartment in which there were three hatch for embarkation / disembarkation of troops. Installing bronekrysh was carried out on all non-floating and floating tracked and wheeled armored personnel carriers from the experience of the events in Hungary 1956 of the year. Lack of roof from domestic armored vehicles has led to significant losses in manpower. Open top car thrown firebombs and grenades from the upper windows of the houses. Besides, armored personnel carriers in the floating bodies completely closed better performance when navigating during unrest.
BTR-50PK returns with a parade on the Red Square. Rectangular hatch in the roof of the troop compartment lid closed clamshell. In the right front corner of the roof of the body clearly visible blower hood
BTR-50PK was able to carry up to 2 tons of cargo or 20 soldier, but delivered to a heavy weapons and equipment he was no longer able to.
The armored structure during normal production were made the same changes, as in the PT-76 tank. for example, on the BTR-50PK in late 1950s. We began to establish a radio station R-113, night vision of the driver TVN-2B, Carbon dioxide fire automatic setup and TDA. BTR-50PK since 1962 g. We began to be issued on the basis of PT-76B and equipped with anti-nuclear defense system and a universal automatic fire-fighting equipment. Installing a third fuel tank volume 140 l made it possible to increase the supply of machines running in comparison with the BTR-50P and BTR-50PK on 150 km. FROM 1968 g. SGMB machine gun began to replace to the PCB, a radio station R-113 replaced by P-123.
On the basis of the BTR-50PK in 1958 It was constructed command and staff vehicles BTR-50PU (750K object), which was intended to ensure the management of mechanized infantry and tank formations and units.

In contrast to the BTR-50PK, the right side of the frontal upper body sheet command and staff car was set navigator niche, having three prismatic observation devices TNP-B. At board sheets housing survey hatches missing, fans, installed on them in previous models, They were moved to the roof of the headquarters branch, its rear wall was carried out without folding the continuous sheet. In the stowed position was attached telescopic antenna on it. On the roof of the headquarters branch housed rotating turret Omnidirection, equipped device TPKU-2B. Two seat hatch with a hinged lid and a porthole, Closes armor cover, They arranged for a turret. Porthole given the opportunity to work in a car during the day without the use of artificial lighting.
Three seats had at the department of management: of the commander, navigator and driver.

The headquarter office of command and staff car was a communication center, which includes a set of wire, radio- and radio resources. In consisted station P-112, -113, -105 or -105U, Two-channel telephone relay station P-403BM, the radio R-311, Telephone field switch P-193A designed for 10 rooms, 4 apparatus, 4 coil length 600 meters of two-wire cable. Internal communication between crew members BTR-50PU carried through two P-negotiating device 120. The machine is equipped with navigation equipment - heading sensor (girokursoukazatel KM-2), kursoprokladčik KP-2M1 and sensor complexion DP. To ensure the operation of the navigation equipment and radio equipped with machine 4 batteries 6-STAN-140M (on the BTR-50PK were two), Portable a gasoline charge unit AB-1-P / 30, 5-th spare batteries 2-ICH-24 as well as various auxiliary appliances. Command and staff vehicles BTR-50PU was equipped filtering unit, automatic fire suppression system, termodymovoy equipment and heating system headquarters branch. The headquarter office in the middle of the table there was a sliding, which worked with the cards. Capacity command and staff vehicle - 9 human.

Subsequently, the BTR-50PU repeatedly upgraded. This is mainly done by changing the composition of the equipment. This led to the BTR-50PUM and BTR-50PUM1. the latest in 1972 year adopted a.
Simultaneously with the development of the BTR-50PU created command and staff vehicles BTR-50PN (an object 905), having a different composition of the equipment.
At the end 1960 s mass production of BTR-50PK completed. According to Western data, fabricated 6,5 thousand. armored vehicles, but this number seems too high author.

combat vehicles, decommissioned motorized troops, served as the basis for the production of several models of special equipment. So, eg, based on the BTR-50PK machine was manufactured system for remote mine clearance UR-67. This machine is an armored personnel carrier, on the roof of the engine compartment which is set the launcher, having two rails. Since it launched unguided rockets, cord having charge - when in the blasting projectiles cleared minefields passage, sufficient to move the art. UR-67 remote mine clearance system was in service in the Royal Engineers.
The upgraded command and staff vehicles BTR-50PUM different from its predecessor, enhanced reservation and more modern radio equipment
Part of the BTR-50P in 1970 years has been converted into a machine breakdown ICC, which is movable means those. ensure infantry units, were armed with BMP-1. BTR-50P production department was created when retrofitting instead of an open troop compartment, having armored roof, and height made it possible to carry out work while standing. Production Department intended for installation, fixtures, tools and accessories for the evacuation, maintenance and repair of the BMP-1. Infantry fighting vehicle equipped with an engine B-6PG and generator G-74. In addition there was a crankcase heater. For installation and removal of nodes and the installation for maintenance and repair of BMP-1, MMP breakdown machine equipped with a crane boom, elements which fit in the stowed position outside.
