Project 639 [1956 draft]
In accordance with the resolution of the Government of the Soviet Union of August 25, 1956, work began on a complex of DRs with BR R-15, which had a range of about 1100 km. The carrier of this complex was to be the nuclear submarine pr. 639 (with three launch tubes ["mines"]) and DEPL pr. B629 (with one launch tube). The tests of the complex were planned to be carried out at Voroshilov and Maxim Gorky (both pr. 26bis), re-equipped according to pr. 33 cruisers.
In parallel with OKB-1, and then SKB-385 in OKB-586 under the guidance of M.K. Yangelya, developed a liquid-fuel ballistic missile R-15 with a range of 1000 km. In 1958 TsKB-16 developed the project B629 - diesel-electric submarine with one R-15 missile. However, due to the large mass-dimensional characteristics of the rocket, it was not possible to obtain satisfactory carrier elements. Work on the project ceased at the stage of the technical design, as well as work on the missile system.
The outline design of the complex was carried out in OKB-1 NII-88, but further work on it was carried out in Dnipropetrovsk in OKB-586 under the guidance of M.K. Yangel. In this organization, by September 1957, they had reached the stage of a technical project, but then M.K. Yangel, referring to the workload of his bureau with other orders for missile technology, transferred work on the D-3 complex to SKB-385.
The fact is that a number of technical solutions obtained during its design have found application in second-generation boats. Among them, one can note the use of three-phase alternating current in an EPS, an HPV system with a pressure of 400 kg / cm 2 and structures of a strong case of large diameter.
The chief designer of SLE-143 VP. Funikov was responsible for the development of the project. And the work was carried out (in contrast to the nuclear submarine pr. 627) on the TTZ developed by the Navy. At the initial stage, several options for deploying missile weapons were considered. The very first of them assumed a horizontal arrangement of the launch tubes, which before the launch of the rockets had to be brought into a vertical position. This design in many respects resembled the one that was planned to be implemented in the process of creating the D-4 complex on the nuclear submarine pr. 667. The second scheme also differed in great uniqueness. In it, the missiles were located in the horizontal shafts rigidly connected to the hull of the ship. To ensure the start of the boat given the maximum possible trim. In the end, they settled on placing missiles in vertically located silos.
Before SLE-143 was an extremely difficult task, because the mass-size characteristics of the P-15 were almost twice as great as that of the R-13. For its storage it would have been necessary to use a launch tube 17 meters long and 3 meters in diameter. This, in turn, predetermined the large diameter of the ship's strong hull in the area of the launch tube location. At the same time, the special difficulty in servicing the P-15 was that fuel components were supposed to be stored in special tanks and to fill them with a missile just before launch. The shafts on the boat were located in a diametral plane. At the same time, their fairing (as well as on pr. 629 and pr. 658) was combined with the fencing of the cabin and pull-out devices. It towered above the deck of the superstructure at 7 m and created great problems for the designers. All the periscopes that existed at the time and most of the pull-out devices had a working length of not more than 11 m. At this length, they did not even provide the minimum required departure when used from a central post. As a result, it was decided to move the anti-aircraft periscope into the combat deck, and to construct additional pipelines in the construction of the commander's periscope and the remaining PMUs, increasing their length to 15 m.
On the nuclear submarine project 639, two versions of the PPU were proposed: with VVR and GTPA capacity of 25,000 hp, as well as with LMT and GTPA capacity of 35,000 hp. The first was developed by NII-8, and the second by OKB "Gidropress". Based on the results of the draft design, SCW-143 recommended the use of a WWII installation on the ship (to meet the project development deadlines), although the LMT provided the ship with an underwater position of 2-3 knots greater.
For the first time in domestic practice, a three-phase alternating current with a voltage of 380 V and a frequency of 50 Hz was assumed to be the main one on the ship. This choice was determined by the fact that with the increased power of generators and individual electric drives, the use of direct current made them bulky and unreliable. Another innovation was the use of 400 kg / cm 2 in the VDN system and the increased number of cylinders that were carried into the space.
The development of the preliminary design project was completed in November 1957 and it was submitted for consideration to the Navy GMK. After it, SCV-143 concentrated its efforts on a technical project. Total in 1961-1965. on SS3 402 it was planned to build 10 submarines on Prospect 639. However, on December 3, 1958, due to the lack of military expediency (due to surface launch, large mass characteristics, a small ammunition on one carrier and the need to refuel the rocket with fuel and an oxidizer immediately before it launch), the development of the D-3 complex and, as a consequence, its carrier, was terminated.
