After testing, the devices “Siren” was returned for revision and revision of the mechanisms, followed by sending in the special forces for use in combat training. Completion of underwater transporters ended in may 1963. In June and July in the Gulf of Riga in the area of Ust-Dvinsk, experiments were conducted on release “sirens” from devices submarines on the go with the divers on Board in a submerged position. March 29, 1965, the carrier of divers-scouts “Siren” was adopted. By 1966 in the battle of the Navy had 12 towers “Siren”: 3 – ktof, 4 -DKBF and 5 in the CFP.
In the years 1960-1962 were working on improved devices “Siren-U” in two ways:
– “Siren-UT” thermal power plant on hydrogen peroxide;
– “Siren-UE” with the electric power plant.
New samples were made a number of improvements, including the location of the divers in the cabins. The development only got the unit with the motor.
In October of 1963 in the area of the lake Berezan was tested stabilizer the depth of SG-PAM on the device “Siren-U”. The stabilizer provides a secure hold of the conveyor at a predetermined depth. However, the apparatus was still far from perfect. In June 1971, on the 1st ground of the Navy in the Gulf of Hara-Lalt measurements were performed for the noise carrier “Siren-1”, and in July of the same year, on a torpedo range in Feodosiya conducted measurements of the level of underwater noise machine “Siren-U”. It turned out that the noise level of the conveyor underwater saboteurs above the level of noise emitted by nuclear submarines.
After careful refinement of the apparatus the specialists of the plant “Engine” appeared highly efficient and reliable specimen, named “Sirena-UME”. Transporter “Sirena-UME” actively offered for sale in all international military exhibitions, where it participates “Rosoboroneksport”.
In 1966, the order of the first Deputy Minister of shipbuilding industry of the USSR Central design Bureau “Wave” was instructed to carry out work on the project ultra-small submarine for special forces, named “Triton-2M”. The construction of the apparatus entrusted to the Leningrad Admiralty plant.
In 1967 began designing the prototype model of the six-midget submarine-Transporter of legkomolyabb “Triton-2” and a new device of type “Triton-1M” is designed for two people.
Design project “Triton-1M” was developed in 1968. In April 1970, the engineering team BSC “Wave” began development of working drawings and technical documentation for “Triton-1M”, which in the III quarter of the same year was transferred to the plant.
Devices “Sirena-UME” at the Fourth International naval Salon IMDS-2009, 27 June 2009
In 1971-1972 at the Novo-Admiralty plant was built the first two prototype “Triton-1M”. Mooring trials of these boats were completed in July 1972, the factory sea trials ended on 10 January 1973.
State testing took place from February 1 to June 9, 1973. June 10, both “Triton” was put to the revision of the mechanisms and colouring after June 30, 1973, was made the control output in the sea. On the same day was signed the adoptive acts on both devices. After adjusting for designers working drawings and documentation of Novo-Admiralty plant and Leningrad Admiralty Association built and handed over to the Navy 32 submarines “Triton-1M”.
“Triton-1M” was a midget submarine “wet” type, which was absent a robust housing for the crew and frogmen in the included personal breathing apparatus were permeable to sea water cabin. Sealed compartments of the small size the boat was designed for the battery type SC-300 and the motor П32М in the rear end. The hull was made of aluminum-magnesium alloy. Control was carried out with propulsion-steering complex of the DRC-1 and automatic control system rudders КМ69-1.
Our database of boats “Triton-1 M” was kept on the keel blocks or on the transport platform. The launching was performed using a truck crane with a capacity of not less than 2 tons. The operation of boats of this type were carried out until the end of 1980-ies, after which they were mostly written off, and some boats ended up in museums.
A good midget boat became the progenitor of similar systems in socialist countries. Yugoslav shipbuilding company “Brodosplit” in the 1980-ies started production of double midget submarine of the type R2-M, which in its layout repeated “Three-ton-1M”. Yugoslav R2-M has a normal surface displacement of 1.4 tons, a length of 4.9 meters, develops underwater speed of 4 knots and has a cruising range of 18 miles.
“Close” relatives “of newt” refers, Polish single midget submarine Blotniak В155 created in 1978 by specialists of the Highest naval school in Gdynia and produced by the Research center of the torpedo weapon of the Polish Navy. The boat was in service with the Polish underwater special forces – FORMOZA. The submarine was developed in two versions – with a sitting and recumbent position of the operator-diver. Chief designer of the project was Lieutenant Begalskaya (J. Biegalski).
It was assumed that the midget boat Blotniak will be transported to the area of combat use of submarines in tow or surface vessels (boats fell into the water with a crane). In exceptional cases, the submarine could “import” into the water by transport truck or dump aboard a transport helicopter from a height less than 5 meters. Now the only instance of the boat is in the exposition of naval Museum in Gdynia, however, he is not genuine, who served in the Navy, and only the reconstruction using the miraculously preserved fragments.
Boats “Triton-1M” was developed long ago and do not meet the requirements that apply to the boats of this class. So SPMDB “Malahit” developed a modernized version of the boat, retaining the designation of “Triton-1M”.
PERFORMANCE CHARACTERISTICS OF SOVIET MIDGET SUBMARINES
Upgraded “Triton-1M” is designed for two people and has endurance of 6 hours with a speed up to 6 knots. The immersion depth of the mini-submarines is about 40 meters and is not determined by the strength of the compartments of the submarine, and the ability of the respiratory system used by divers. The hull shape is made smoother, which allows him to develop more speed at a lower cost of electricity. Battery as an energy source on upgraded variants remained, but now the developers are considering not only a silver-zinc or acid batteries, but lithium.
It is clear that domestic midget submarines are quite “on the level” world of samples and represent a significant component in the system of naval arms.
