In the stowed position, the antenna is held against the bottom of the fuselage. The search team and attack helicopter Ka-27 to combat the submarine is dismantled. Instead, a set of radio-electronics has been installed to target detection radars, the objectives of the identification and transmission of water in the air and the data of the situation based command posts ship and ashore.
