Super high speed hydrofoil torpedo boat with 533mm torpedoes and 23mm autocannon turrets; Experimental Boat
History:
Project 125 of a hydrofoil torpedo boat with a displacement of 60 tons was developed by TsKB-19 under the leadership of Chief Designer V.M. Burlakov. Design work began in 1954. According to the project, the steel hydrofoil boat had such dimensions that it could be transported by rail to anywhere in the country. The boats received, in addition to two diesel engines, an afterburner gas turbine and were supposed to reach speeds of up to 68 knots.
The Xenon 125 radar for Project 125 torpedo boats was developed at the Omsk TsKB-373. It became the first monopulse radar for Navy boats. Under his leadership, a full development cycle was carried out, a pilot batch was produced at the Karl Marx Plant, testing was carried out as part of the complex and handed over to the customer.
Each side of the rear part of the boat has a 533mm torpedo tube, the torpedoes are pushed out by compressed air from the tail (same to German V-990 in the game). Consider the time it built, the torpedoes are considered to be 53-56, same to Pr.206.
The boats had a bow and stern 23-mm twin installation AN-23. The AN-23 was a modification of the upper turret gun mount of the Tu-95 bomber. The unit was developed at OKB-43 (since 1967 MZ Vympel). The AN-23 mount had 2 aircraft 23-mm AM-23 assault rifles. The automation worked by removing gases from the barrel bore. The barrel is a monoblock. The bolt is wedge-shaped. The machine is fed by a belt.
In 1959 1960, two experimental torpedo boats TK-75 and TK-76 of project 125 were built at the No.831 “More” plant in Feodosia. Project 125 hydrofoils were supposed to reach a maximum speed of 68 knots. At the same time, in calm water, the boats developed an even higher speed up to 73 knots, on a level 3 wave they gave no more than 45 knots.
On the boats of project 125, it was possible to try out many new technical solutions. In particular, comprehensive studies were carried out on various options for the wing scheme of the boat, including a low-submersible wing in the bow and stabilizers on the sides.
Tests have shown that already at sea waves of level 3, the speed cannot exceed 40 knots, otherwise the vibration of the hull and the load on the diesel engines increase sharply. The gas turbine rusted quickly. Habitability was poor.
The torpedo boat “TK-76” was laid down in Feodosia at the shipyard No.831, completed and entered service with the Black Sea Fleet in 1962. In 1968, it was reclassified as an experimental boat and renamed OK-743. In 1969, the boat was excluded from the fleet, and erected as a monument in Feodosia. Subsequently, it was dismantled and scrapped.
