"- The upgraded Ka-52M will be able to carry the latest product 305 cruise missiles. This helicopter helicopter can effectively hit any ground targets - including armored vehicles - at a distance of up to 100 km, a source in the military-industrial complex told TASS .
The interlocutor of the agency added that the modernized Alligator has an improved sighting and navigation system, the avionics of the cockpit and the screw group have been improved.
Earlier, another source in the defense industry told the agency that the “305 product” had passed combat tests in Syria. In time, they coincided with testing in conditions of real combat of the upgraded Mi-28NM Night Hunter attack helicopter.
Then , the first mention of the “305 product” appeared in the media . The flight range was modestly designated - "over 25 kilometers." The coordinates and target data are entered into the rocket before launch, the “product 305” overcomes most of the way under the control of an inertial navigation system, and when approaching the target, the homing head is turned on.
It is equipped with highly sensitive sensors operating in different ranges of the spectrum. The missile can be guided by the mark of the laser rangefinder-target designator, the heat radiated by the target, and also broadcast the picture from the camera to the helicopter cockpit. The weapon is protected from interference, is able to distinguish the target among infrared traps and operate in the "shot-forgot" mode.
The range of missiles from the current arsenal of combat helicopters of the Russian Aerospace Forces exceeds 15 kilometers. New weapons will allow front-line aviation to hit targets without entering the enemy’s air defense zone."
You got a different source of the product 305 or izdelie 305 missile with a different range? Where the source was originally from https://tass.ru/armiya-i-opk/7767415 I am guessing its a newer variant or version.
