Halibut class SSN

http://img42.exs.cx/img42/6978/SSN-large.jpg

OVERVIEW:[/ib] This new design from IDF Shipyards is going to revolutionize submarine design. This sub goes away from the trend of larger, less maneuverable subs and goes back to the basics. This sub is very fast with a sustainable speed of 42 knots. It's titanium hull allows it to survive some torpedo hits and dive deep. The liquid metal reactors provide great speed while the reactor pumps keep the sub quiet. New 7 bladed screw designs are quiet and help retard cavitation bubble formations.

[b]length: 315 feet
beam: 38 feet
displacement: 5,950 tons
speed: 42 knots
powerplant 2 x Liquid metal cooled reactors providing 48,000 SHP
DEPTH:
Operational diving depth: 2,100 feet
crush depth 2,400 feet
crew: 9 officers, 72 enlisted


WEAPONS:
6 x 21 in torpedo tubes (rack space for 36 weapons)
12 x VLS tubes

Radar: Navigation/fire control/surface search; Sperry BPS-15G

SONAR: IBM BQQ-10C/D
BQG-5D (flank array)
TB 25/32 thin line array
AMETEK BQS-20
MIDAS mine and ice dectection

Special Features:
BSY-1 Fire control computer
rubber coated absorbs sounds while aenoich coating absorbs active SONAR.
Titanium hull allows deep depth and a hard to kill hull.
Liquid metal reactors provide good speed

PRICE = $1.5 BILLION

OOC:you are getting better at drawing these ships....

thanks. This is my 1st attempt with a submarine. I'm finally figuring out how to make MS Paint look good, although Print shop would be a whole lot better.

Looks nice. The Incorporated states would like to aquire a dozen to help shore up our budd2 fleet, with the possibility of aquirering more.
--------the amount of 18 billion $ is ready for transfer upon confirmation----

Thank you. And it's always a pleasure.

excuse me being an ego-centrist, but I added a poll to boost my already shattered (or overinflated) ego

Please post suggestions along with your votes so the updated versions of this sub can be improved to meet at least some demands. (these changes will be applied to those already ordered since the keels haven't even been laid down yet)

I like the concept, and have already ordered some. A A, no question.

Is there anything you'd like to see improved or added? Any feedback from anyone is very helpful.

I'll have you pay over a 10 year period in installments. I will deliver 5.5 a year (meaning 5 one year and 6 the next for 10 years)

The Concordiat would like to purchase 10 Halibuts.

--------------MONEY WIRED ON CONFIRMATION------------

This looks like it was deeply inspired off the Soviet Alfa Class Submarine. And I was wondering how you solved the problems of this submarine. The Alfa was extremely noisy at high speeds has this been solved. I also wonder why you picked the liquid-metal reactor over a conventional one. Liquid metal reactors are more complex because they require a heater to keep the metal in a liquid state. The soviets had incidents where the heater was turned off or broken and the metal would harden up destroying the reactor rendering the SSN unusable. What is your justification for this reactor and what benfits does it provide. It would seem that the reactor would just create more problems than it solved.

The reactor and hull material are based off the Alfa. The alfa's noise was a result of poor reactor pumps (a plague of the Soviet Navy and one I fixed). The screws were of a very poor design. According to someone I know who spent the 1970s and 80s in the US sub fleet, the Alfa's had screws which were so poorly designed that they'd "sing" at high speeds. I changed the screw design here to accomodate an improvement of current US designs (based off of USS Seawolf propulsion system).

The Sturgeon also weighed heavily on this design in terms of maneuverability requirments and other parameters. Everyone is operating larger Los Angeles, Seawolf, and Virginia SSNs. The Sturgeon was good and manueverable, but old. I brought back ths manueveribility and size that made Sturgeon a better sub in in shallower waters (and given my geographical situation that was very necessary).

I know of the reactor problems the Soviets had, but that was because they were very poorly designed by a government that didn't give a shit for it's people and sailors. IDF cares greatly about our sailors and subs. There are dual heating systems to help in case one may be disabled and they are well maintained (unlike the Soviet counterparts). The reactor was chosen for the speed that the sub could be provided with and that is one thing we wanted, although like any other sub there will be considerable noise at high speed.

In that case we would like to purchase thirty Halibuts for 45 billion USD to be delivered 5 a year for the next 6 NS years with 7.5 billion paid each year for the next 6 years.

confirmed. Thank you for doing business with us.

I'll take 8 of them for interdiction of slave trade operations. $12 billion wired on confirmation

[OOC: It looks like a decent enough drawing on the sub itself, though the picture does strike me as being more similar to an SSBN or SSGN than an attack submarine. But that's nitpicking on my part.

I may be off base with this, but I think having six torpedo tubes for 21" torps on a sub of that relatively small size might be a bit optimistic, especially if you want it to keep the 42 knot speed. I'm not sure how you accounted for the speed being two knots faster than the Alfa while fixing the reactor problems Nutropinia brought up.

My impression with this design is that it might be a great sub for scouting the enemy out and launching a hit-and-run attack, but it may have to swarm the larger, more heavily armed SSNs.

Then again, subs aren't my area of expertise. Looks good overall, though I was hovering between a "B" and a "C." Then again, you're looking at someone who tried to design a hybrid SSBN/SSN...]

The 42 knots isn't too much for that many tubes, considering that it is revealed that the Seawolf class' top speed is actually slightly above 40 knots (alfa went 45 knots). The 6 tubes isn't too much for that size since the much smaller Upholder class has 6 21 in TTs. The reactor problems aren't taking up too much space since it is to be noted the Alfa's reactors weren't that large. This sub is meant for hit and run. I'll stick to Galaxy and Seawolf for massive attacks.

The IDF Navy needed a smaller Sturgeon like SSN and that is why I built this.
