Viper-72 thermal sight ,A Syrian solution

 since the SAA armors engaged in the ongoing war in Syria in late 2011 Syrian tanks been suffering from many maintenance problems due to the complexity of the urban warfare .
many old systems on SAA tank have proven to be unreliable and unsuitable for urban warfare among them is the TPN-3-49 night vision sight on T-72 tanks ,as SAA T-72 tanks start to take on the streets it become clear that protecting the IR lamps from the enemy fire is impossible just like the idea of fixing it again and again
after two years into the fight most of the tanks in urban area have lost it's night capabilities with all or almost all of it's IR lamps broken some even the TPN-3-49 night sight it self .
when the Syrian scientific research center was tasked with finding a solution for this problem in 2013 they were fast to come with an idea for the perfect replacement 
a thermal sight ,as thermal vision don't need illumination ,and they have already some experience working with thermal sights 
the Syrian scientific research center did before upgrade some of SAA's T-55MV with a Syrian thermal sight for direct engagement.

so the work was on and soon after the Viper thermal sight was born to replace the existing night TPN-3-49 vision sight .

Viper in outer design is similar to TPN-3-49 but with an arch shaped protection ,it also use many of TPN-3-49 components .

Viper range is up to 4km for big objects ,however the useful range for aiming is 1.5-2km tops
the tank gunner aim through an electronic scoop ,however an LCD can be attached .

as firearms flash is more visible in thermal imagery ,Viper is used even in day to detect snipers in urban areas ,giving the Syrian tank crew not only a better vision with less maintenance but also with a chance for revenge ...


  1. This is very welcome divise for today's urban battle warfare, thank you so much for your research and sharing.

  2. Very interesting info in someway related to belarrusian Peleng or early russian Sosna-Thales Catherines?

    What are the sources for the photodetectors? Resolution?

    Any new info would be much apreciated. Thanks in advance
