🧵A thread discussing the troubled development history of the PMT-100 and PMT-150 series of field pipelines: The Soviet Union's initial large-scale operational experience in supplying military units with fuel under combat conditions was acquired during the engagements near Lake Khasan (July–August 1938) and along the Khalkhin Gol River (May–September 1939). During these campaigns, logistical support for the 1st Army Group extended across a supply route of approximately 515 kilometers. Of this total distance, 260 kilometers were serviced by rail transport, 95 kilometers by motor vehicles, and 86.7 kilometers by horse-drawn carts. The final leg of the supply chain required fuel to be transported in specialized containers via pack animals and manual labor.

As military activity in the region intensified, the throughput capacity of the supply system grew to between 500 and 750 tons of fuel per day, delivered using a combination of transport modalities. The rising demand for fuel, particularly by armored units, emerged as a critical logistical concern. The concentration of tanks in the theater of operations increased markedly, resulting in fuel requirements measured in tons and millions of liters. This placed substantial strain on logistical capabilities and exposed significant operational vulnerabilities. These experiences were not only retained in institutional memory but were also subjected to detailed analysis by the Soviet military leadership.

The lessons derived from these campaigns played a decisive role in shaping the USSR’s approach to logistical support and directly influenced the conceptualization of field pipeline systems.

In December 1940, a meeting of the senior leadership of the Workers’ and Peasants’ Red Army (RKKA) was held. It was devoted to ways of further developing the military and conducting operations, taking into account the exercises and experiences of the war between Germany and France. Participating in the meeting was the head of the Red Army Fuel Supply Directorate, Major General of Tank Forces P.V. Kotov. By that time, information had already been obtained that the logistical services of the German armed forces, especially their tank and motorized units in the campaign in France, had used field pipelines to deliver fuel.

After the war began, engineers D.Ya. Shinberg and T.E. Khromov sent a letter to the People’s Commissar of the Oil Industry, I.K. Sedin, proposing the creation of a front-line collapsible gasoline pipeline 100 km in length, and longer if needed. For use in a fuel supply system, it was assumed that mobile pump stations mounted on truck chassis would be used.

Commissar I.K. Sedin approved the idea and, with the support of the leadership, allocated funding and authorized the design and development of the field pipeline. The proposal was adopted and approved in record time. The pipeline was planned to deliver fuel to the troops conducting defensive operations west of Moscow, in the area of the town of Khokhloma.
However, the front line in these areas in the fall of 1941 was quite unstable; the German forces, although suffering heavy losses, continued to advance. Plans to create and use a collapsible pipeline were not realized.

Over time, renewed attempts to supply fuel to troops using collapsible pipelines became more successful. For example, in April 1943, field fuel pipeline operations were launched. However, their broader use remained limited due to the lack of necessary equipment (pipes and pumping units) and, most importantly, due to a lack of practical experience.
During the war, significant experience was accumulated in building and using both permanent and field pipelines. One example studied by the USSR was the American fuel pipeline system laid along the Ploiești–Rhine route.

Modern (for the time) tanks, motorized vehicles, and field electrical generators, powered by gasoline or diesel, entering service in the Red Army, significantly increased the demand for fuel. To support an uninterrupted fuel supply, new approaches had to be found.

A short history of the Il-76 concerning its role in the delivery of paratroopers: The early Cold War proved to be a favorable period for the VTA (Military Transport Aviation). After just a decade of existence, they had seen the complete integration of equipment designed with the express purpose of meeting their needs and operated an impressive 650 aircraft. By the 1960s, 80% of VTA regiments were equipped with the An-12, which arrived in batches of 100 each year. Despite this, even with the introduction of the An-22, the VTAs' lift requirements had not been met. For all of the advantages offered by turboprop designs, the limitations experienced in speed were becoming a problem, especially when delivering paratroopers (an endeavor that favored expediency).

This was recognized internationally, and with the introduction of the C-141 Starlifter, the USSR were properly motivated to respond with their own jet-powered airlift. Furthermore, Ilyushin, after the failure of their Il-60 proposal, needed to get a new aircraft into military service, which led to unique importance being placed on innovative design solutions.

A short thread discussing the individual parachute technology of the Soviet airborne forces: The D-1 family of parachutes, initially developed in 1955, was an important step in the modernization of the airborne forces. Before the introduction of this system, significant skepticism surrounded the concept of a parachute with a round canopy. This configuration was believed to be unstable when compared to the traditional square canopy design employed by earlier models. Of course, after tests were conducted involving the D-1, it was found that this was indeed the superior layout, which led to its adoption shortly thereafter.

🧵A thread discussing the history of Maneuver (automated command and control system):
Overview:

In May of 1964, by decree of the Central Committee of the CPSU, and the Council of Ministers of the USSR, development began on the possibility of automating troop control systems within the Soviet military. Immediately, as a result of this request, a research group led by Colonel Fedotov at the Frunze Military Academy was established, aimed at determining if such systems would be functional from an operational + tactical standpoint. These studies concluded that if such an endeavor was to be seriously considered, automated systems and communication complexes could not exist separately. If Maneuver was to achieve complete superiority over enemy command and control, it had to be integrated alongside serious revisions to the entire C&C matrix of the Soviet Military. Work on a system that would harmonize Communications between strategic, operational, and tactical formations began at OKB-864 in Minsk. Due to the importance of Minsk Electromechanical Plant Number 864, the OKB soon became a part of the Research and Development Institute of Automatic Equipment in 1969, and in 1972, all of its efforts would shift towards R&D related to Maneuver. Yuri Dmitrievich Podrezov was appointed director of the Design Bureau and later Chief Designer of Maneuver.
