If you look at the domestic Su-34 aircraft, then on some of them you can see an extremely strange yellow cockpit lantern. This raises a number of questions. First and foremost: why does the glass of a combat vehicle have such a color at all? Second: why is this being done and does such a design solution cause any inconvenience to aircraft crews?
The Su-34 multifunctional combat aircraft was developed back in the Soviet Union. The first test flight took place in 1990. The collapse of the country and the 1990s that followed it delayed the release of the 34th in the series for a long time. By 2008, the aircraft had finally completely eliminated the shortcomings identified in the early 1990s, after which its production began. The fighter-bomber was officially put into service with the Russian Aerospace Forces on March 21, 2014. To date, 112 such aircraft have been produced.
Interesting fact: in the NATO classification, the Su-34 is denoted by the word "Fullback" - "Defender". The NATO verbal codes for military equipment have no semantic meaning, just all fighters (and the Americans consider the Su-34 to be a fighter) must begin with words with the Latin letter "F".
If you look at some of the successful photographs of the Su-34, you will notice that the glazing of the aircraft gives off a yellowish glare. With the correct incidence of light, it becomes clear that the canopy of the Su-34's cockpit is almost yellow at all. In the vastness of the network, there is even a legend that gold plating is added to Su glass. Most likely, this is precisely a "legend", however, it will still not be possible to verify it.
The fact is that the characteristics of glass for combat aircraft (as well as the characteristics of the absolute majority of other parts) are strictly classified, they are a military and state secret for the disclosure of which knowledgeable people face severe punishment. Nevertheless, the yellowish tint of glass is not a difficult thing. In fact, this is the same as the yellow soldier glasses (which American soldiers love so much). It's just an anti-reflective coating that should improve line of sight on occasion.
