And second, the Navy claims that the construction of SSN-23 is necessary to preserve the industrial base in nuclear submarine construction until the next class of attack submarines (the NSSNs) commences in FY98.
SSN-23 is not needed to preserve the nuclear submarine industrial base until the next class of nuclear submarines can be built for several reasons.
And third, it is not true that most of the skills needed for nuclear submarine construction would "wither away" and have to be reconstituted if no more subs were produced until construction on the NSSN begins.

  Submarine - MSN Encarta
Submarines of the 1700s and early 1800s were larger in size than their predecessors, but were still primitive hand-powered ships, with rudimentary and often ineffective explosive weapons.
Submarines are valued for their ability to roam undetected in the ocean, and many navies operate submarine fleets.
Because of their mission to deter attack on their respective countries, ballistic missile submarines are designed to operate with extreme quiet in deep ocean patrol and evade detection during their patrols, which last from a few weeks to as many as 70 days at sea.

 Submarine Frequently Asked Questions   (Site not responding. Last check: 2007-11-07)
Attack submarines (designated SSN and commonly called fast attacks) are designed to pursue and attack enemy submarines and surface ships using torpedoes.
To drive to the surface, the submarine simply positions its planes (i.e., stubby "wings" at the stern and on the superstructure or bow of the submarine) to rise and the submarine ascends to the surface.
Submarines are always deployed in the oceans around the world, and with their nuclear reactors and great speed are often the first ships on station when a crisis develops.

  NU NROTC - Submarines - What will you do?
Submarines, their officers and crew are heavily relied upon for anti-submarine warfare, anti-surface warfare, land attack, strategic deterrence and landing Special Operations forces.
During a sea tour, submarine officers may be in charge of any number of tasks, including the safe operation of the nuclear reactor, maintaining the ship's torpedoes, cruise missiles, ballistic missiles and sonar, charting the ship's position and operating communications and intelligence equipment.
As a submarine officer, you will be specially trained in the nuclear field and assigned on a nuclear-powered attack submarine or a nuclear-powered fleet ballistic missile submarine.

Modern attack submarines are known as fast attack subs and generally operate in the Hunter-killer role.
Submarines did not have a major impact on the outcome of the war, but did portend their coming importance to naval warfare and increased interest in their use in naval warfare.
Submarines are popular subjects for films due to the danger, drama and claustrophobia of being on a submarine, and the suspense of the cat-and-mouse game of submarine or anti-submarine warfare.

 Submarine Attack Course Finder Mark I Model 3 Manual
The device on the obverse side is a form of the well known "Is-Was", or submarine attack course finder devised by Captain Nasmith, ??.N. That on the reverse side is a form of circular slide rule or speed omnimeter arranged to solve for enemy speed with data secured during the approach.
If the other vessel has drawn ahead, actual intercepting by the submarine will not be possible, but it might prove possible to reach a position within torpedo range as the enemy crosses ahead, in which case the intercepting submarine should maintain the course and steams at highest speed.
An experienced submarine commander noting the rate of change of bearing, the angle on the bow of the other vessel, and the range, will know whether or not it worth while to continue with the approach under these conditions.

Using their inherent stealth, the modern attack submarine is the only effective ASW platform.
Submarines, ours and theirs, use the environment to their best advantage, and only a platform operating in the same environment stands a chance of finding a modern submarine.

 Nuclear submarine collides with an underwater mountain   (Site not responding. Last check: 2007-11-07)
The nuclear attack submarine USS San Francisco which was on its routine route for a port visit in Brisbane, Australia has dashed on an unknown underwater mountain in its way.
The mountain that surfaced in the vessels way was no where on the submarine’s navigational chart and it appears that the vessel had not strayed away from its path.
Submarines don’t use active sonar to navigate their way as doing so can easily let enemy forces track the position of submarines.

However, if the submarine came to the surface to give fair warning, she herself became vulnerable to attack (by ramming, by concealed guns, by warships rushing to the rescue).
Submarines themselves employed more natural schemes of camouflage, typically to blend in with operating conditions: white for arctic waters, different shades of gray for different parts of the world.
Submarine pioneer Admiral Chester Nimitz assumed command of the U. Pacific Fleet on December 31, 1941 — on board the only available undamaged warship, the submarine "Grayling." The aircraft carriers were at sea.

 Kaiten Suicide Submarines
Thus, with the invasion of the Phillipines, the Japanese first formulated and implemented 'Special Attack' tactics in the form of suicide aircraft attacks: the kamikazes.
The 'normal' attack method (if one can call it that) was for a mother sub carrying from 4-6 kaitens to approach the target area, locate the target vessels, and then release her kaitens to attack at a range of between 6-7000 meters.
On the whole, though, they were a miserable failure, and their war record certainly did not justify the expenditure of over a hundred kaiten pilot's lives during the last months of the war.
