The second post of mine is dedicated to the general line up of the Soviet 4th generation projects.

The smallest of these was the project 957 (aka Kedr), this was intended as a small, cheap submarine, built with more emphazis on the sub hunting. It was using the common sonar set, which was desighned for all 4th generation submarines to use, which consisted of a spherical, conformal and towed arrays.

It was also using a standartised 4th generation powerplant - the monoblock KTM6, however the powerplant was not availiable by the time Soviet Union broke down.

In over all ideology of the project it was quite simmilar to the Los Angeles class (and now Virginia class), with a sinlge hull, 4 torpedo tubes and separate vertical launchers for 533mm calliber cruise missiles.

The submarine was intended to be produced after the project 945AB submarines were completed on that same plant, the work on 2 hulls was started but was never completed.

The second 4th generation project I would discuss in this post is the pr.881 mamoth, which was intended as an Oscar replacement with anti ship mission in mind. Due to the improvements in the US Carrier groups ASW capabilities Soviet designers felt that there was a requirement for a longer range, faster sub launched weapon.

Such weapons (the Bolid) were created, however due to their huge size an even larger (than Oscar class, as it could hold only 12 such weapons) submarine was desighned using standard 4th generation subsystems (sonar, powerplant and so on), there also was a Yahont armed variant of this submarine.

Both of those projects (with the exception of two project 957 hulls in production) were cancelled for the project 885 submarine, which was seen as the -do it all- multirole sub, even though all 3 were intended for production in paralel.
