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

-
Image
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

-
Image
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 ...

Progression of thermal imaging sight housings on Soviet AFVs

-
Image
Throughout the development cycle of thermal imaging sights during the Soviet Union and subsequently Russia, engineers designed several variations of covers to protect newly developed tech. Ranging from simple covers to semi/fully-mechanised systems.  The "AGAVA" series of thermal imaging sights was one of the earlier systems to be mounted on Soviet tanks dating back to the 1980s. The first sight iteration mounted on a T-80B utilized a simple protective housing with a hinge-mounted frontal cover. The front cover would be opened using a pull-string mechanism.  AGAVA on T-80B AGAVA on T-80B "AGAVA-2" made an appearance on T-80U, UM and UK tanks in the early-mid 1990s. The newer iteration still retained the same hinged door mechanism with a pull-string while also receiving a new roof cover which served as additional protection against variable weather conditions.  AGAVA-2 on T-80U - Swedish trials 1994 The overall complexity and ease of operation for this sight underwen...
