In the past few months, the conflict in Ukraine has been making headlines. As a buyer interested in military technology, I have started paying attention to some weapons and equipment, especially the Kamov-27 helicopter. This is a former Soviet Navy military helicopter widely used for transportation and anti-submarine missions. According to historical information, the design work of the Ka-27 began in 1970 and the first prototype flew in 1973. Its purpose was to replace the Ka-25, which had been in service for ten years. Because it was required to use the same hangar, the Ka-27 was required to have similar exterior dimensions to the Ka-25. Like most military helicopters in the Kamov family, it uses a coaxial rotor system and does not have a tail rotor.
