Armed with long range ballistic missiles, the Telyatir is the principle Coastal attack submarine deployed by the TANMB. The ships speed is enough to help it keep up with other the Lasnekovir class of which it compliments, making her a valuable fast response craft. She is heavily defended, with a potent armament of turrets and short range weaponry, and still retains some Sub-to-sub/Sub-to-ship torpedo weapons. The major weakness of the design is the maneuverability. Her turning circle is appauling, as she is such a heavy ship to spin, making her susceptible to torpedo attacks.

CONT:

One of the major problems with previous designs of SSBF submarines was the noise of the fusion reactor. A SSBF is meant to sneak up to its target and unload a firestorm of missiles at its target. In order to succeed in this task, it has to be difficult to detect. This was a problem. By default, fusion reactors are noisy machines. Not by the reaction itself, fusion of cells does not create audible noise but the cooling systems create severe noise. Standard cooling systems of the period pumps water from outside and channels it through cooling coils. These coils run directly through the reaction chamber, cooling the chamber and stopping a fusion overload. The pumps required to pull the water into the coolant system are very noise-inefficient, making it relatively easy for most ultra-sonar sensors to detect the vessel. This was the main issue with the previous class of SSBF: the Echo class, constructed by Aurora Oceanic Engineering, based in Brittainian-Principiladia. There were two options to remedy this. Either develop some way of reducing the noise of a pump, or engineer a new method of cooling. The latter was the ticket. Instead of using a complex system of pumps to intake water, a series of pressure-sensitive valves jet cooled air into the coolant coils. The air is extracted via non-moving filters from the water around. The jets, using a pressure system, do not have any moving parts, eliminating the noise pollution that previous ships possessed. When the Telyatir first came into production, she was the quietist submarine in existence, far more stealthy than any other race or the Terran equivalents. Nowadays, the new Demitrayev class incorporates a new model of the coolant system, making her quieter still.

I really don't see how this thing can be at all stealthy. The sheer mass of it alone will be screaming out to any sensors looking for it, and if it starts moving it'll be even more obvious. Subs are small for a reason.

[Reliant121]

Detection systems dont work in the way they work now. they dont search for mass. If they searched for mass, then anything like a large fish will set it off. This isnt only designed for Terran waters, she is designed for alien waters as well with different density, different characteristics. Most surface/sub-surface scanners, termed as sonar purely because the Terran's are complete nostalgia freaks, work on sound waves. Ultra-sonar, the most common type of sonar, is capable of picking up the vibrations caused by sound. Literally, ultra sonar "listens" for its target. Admittedly, It cannot be completely stealthy, Because the cavitation of the water-jet engines will automatically cause some sound but it does dramatically reduce the sound produced.

[Reliant121]

Terran sub mentality is different to other races as well. Terrans make big long submarines, similar to ours today. But all the other races, Bar the Nishari, only use tiny 1-5 man fighter-like subs. They act like mosquito's to Terran ships. Small and fast with ok armaments, pinpricking. Hence most Terran subs carry defensive turrets. The Torpedoes are for large subsurface installations or surface warships. The ultra sonar picks up the vibrations of the craft. A small craft darting about makes ALOT of vibration, making it alot easier to detect alien craft's vibrations instead of its mass.

[Sionnach Glic]

Even if they only detect sound vibrations, the sheer size of that thing should set one off pretty easily.

[Reliant121]

It depends. It would set it off, yes but it could be recognized as a whale or some-such. It really depends on the proficiency of the operator. And speed. At slow speeds this thing is just like a very very big whale, and there is even a species of whale on New Terra that is almost as big, the Lanstrum whale. But each knot makes it more and more detectable. Normal practice is to sneak in at maybe something as low as 3 knots, barely making any cavitation and making friction. Higher speeds monumentally increase the detection ease. If this thing was going top speed, it'd be like a christmas tree in a dark field.
