Speed of a submarine .....?

Question

What is the speed of a submarine in general cruise and during action ?

Answer 1

Their mission determins their speed. The faster they go the more noise they make, more noise easier to detect. So, a missile boat will loiter around in their op area at about 3 knots, but the newer ones are capable of speeds in excess of 50 knots

Answer 2

There isn't a submarine made that can do 50 knots, not even the titanium hulled Russian boats. Damn, that would outrun our Mk 48 torps.

The actual speed of US submarines is classified but I can tell you that it is greater than 20 knots but less than 50 knots. Nuke boats are very quiet at speeds greater than 2 or 3 knots. Don't know what a surface deck ape would know about submarines, gunner.

The main advantage that we had over the Soviets is our SONAR capabilities. Our boats weren't quieter than theres, they just couldn't hear us because their SONAR wasn't as sensitive as ours.

Answer 3

Exact speed is classified. For public information on any currently operating submarine go to the library and look in Janes Naval Forces reference book.

Answer 4

Sub speeds vary widely depending on how quiet the propellor is. Most nuke boats can travel quietly at 2-6 knots. At high speed they can travel at 30-45knots but this means that everybody can hear you. So these high speeds are only used when in transit to a patrol area then they will patrol at their quiet speed. Also subs have two general speeds surface speed which for most nuke boats is about 20-25 knots and submerged speed which I already listed. This is because the hull is shaped for underwater proformance instead of surface speed.

Answer 5

Better sit in the submarine and calculate the speed.

Answer 6

la classification sub has a rated floor velocity of 20kn (23mph) compaired to its underwater velocity of 32kn (36mph). A swifter sub underwater would or won't have a swifter floor velocity. approximately 25kn or so would desire to be nearing the utmost. the utmost velocity of any gadget the version between the strain of its propulsion equipment and tension brought about by ability of drag. For a submarine, drag will improve dramatically on the exterior because of the fact the water flowing around the hull meets air. This disrupts the graceful flow of water around the hull of the ships. you in addition to would have the priority that submarines are frequently designed to maximise underwater velocity. because of the fact the conning tower supplies extra drag on the right of the sub, the propulsion equipment relies intense and/or the hull is designed such that they supply a tension to counter the tendency to flow nostril-up.on the exterior, the drag from the conning is long previous so the submarine's propeller has a tendency to tension it slighly nostril-down. utilising planes would desire to be angled to counter act this tension -- including extra drag. Propulsion is likewise decrease on the exterior because of the fact the propeller is way less effectual close to the exterior - the place water can no longer easily flow to the propeller, the flow of water around the propeller is larger decrease than the deliver than above, and air gets jumbled in with the water -- making it much less dense inflicting much less tension to be utilized to the propeller.

Answer 7

The official version was "greater than 20 knots" Anything else is classified.

Answer 8

60 knots

Answer 9

Damn, I really hope that guy is not a terrorist. You may have just helped him out alot.

Answer 10

36 km/hr
