BMP-3 production showcase development

-
TV Zvezda has released new footage covering the production of BMP-3 IFVs. Showcasing various footage of hull and turret production along with how factories refurbish/repair old or battle-damaged hulls and turrets to make new vehicles. The footage presented does not reveal any major changes in the production scale of BMP-3 IFVs. 

This post expands on the topic of up-armouring vital components of the BMP-3 carried out by Kurganmashzavod. The previous article can be found here. 
This article will not cover the armour packages presented in the analysed footage! 

A double-shutter mechanism is used in the housing, which has two functions. The small shutter protects the optics from direct hits and can be opened/closed during combat or marches. The small openings have special cutouts, which minimize the chance that the optics (laser channel, day channel and thermal imaging channel) are hit by shrapnel or bullets. 
The large shutter, which holds the small shutter is used to service the sight from the outside and has its own hinge on the right side.

The creator of the sight, Andrey Popatov, claims the housing is made entirely out of steel, but does not specify further composition details.

It is also shown how the small shutter opens using a spring-loaded hinge, which actuates when no negative force is created by the pull string. The pull string is operated by the gunner from inside the tank. Interestingly enough, this new housing also has 2 pneumatic cleaning nozles, which clean the optics using high-pressure water.

"AGAVA" - "AGAVA-2" and its confusing history

When covering Soviet sight technology there are always some interesting designs and approaches to solving an issue. It is a common fact that the Soviet Union in the 1980s-1990s was quite behind in thermal sight technology. Only in the 1990s, but to be specific in 1992, the Soviet Union now Russia started to field small batches of thermal sights on their tanks, primarily T-80Us and some of the early T-90 variants, which just recently entered service. Russia's journey through creating its own domestic thermal sight traces back to 1982.  The 1980s were quite an important time for the 'Krasnogorsk Factory named after S.A Zverev', which is still to date an Optical Engineering and Optoelectronics factory. The factory is primarily known for making domestic Soviet cameras back in the day. However, that's not the only thing that the factory has produced back then.  Close to the mid-1980s, the facility was contracted to develop new thermal sight technology for the Soviet Ministry

GTD-1000 - GTD-1000TF - GTD-1250 Gas Turbine Engines

The world's first mass-produced tank gas turbine engine GTD-1000T was created at the Klimov Plant in 1968 for the T-80 main battle tank developed By the special tank design Bureau of the Kirov plant (now JSC "Spetsmash"), which was adopted by the Soviet Army in 1976. Since 1980, a modification of the GTD‑1000TF for T-80B/BV tanks was produced, since 1986 a modification of the GTD-1250 for T-80U tanks.  GTD-1250 Engines of the GTD-1250 family as part of the power plants of T-80 tanks are in service with the armies of Russia, Belarus, Cyprus, South Korea, Kazakhstan. Turbine engine GTD-1000T/GTD-1250, which have a large volume-weight  capacity and a more favourable traction characteristic compared to diesel engines, provide T-80 tanks with interesting characteristics: - higher operational readiness - easy start-up at low temperatures (up to -40°C) - better cross-country ability on soils with a low load-bearing capacity - best noise and heat-masking qualities - increased &qu

A new sight for the modernized T-90

  Back in 2018, a new programme was started. This programme's focus is to create domestic equipment for Russian armoured vehicles, specifically optics. This is so that the Russian army can stop depending on the french company "Thales" and their Catherine technology. T-72B3 received new internal components for the Sosna-U sight, phasing out any foreign components. As for the T-90M/T-90MS, something else was done. Previously, the T-90M/T-90MS employed the Sosna-U sight, which featured french components from Thales. However, the internals of the sight was not simply replaced. This time, a completely new domestic sight was created under the name PNM-T. The sight was reportedly made by the PJSC ANPP TEMP-AVIA in 2018 or 2019. The first appearance was in the Telekanal Zvezda show, during the episode about the Proryv-3 (T-90M). In this episode, a new plaque can be seen with the name of the sight. Its first public physical appearance, however, was at the Army-2019 event. The doo
