This leads to reduced engine size and increased range. Traditional Deep'V' hulls have two modes of operation, low speed displacement mode and a high speed planing mode. The vessel may operate only at displacement speed or planing speed. The VSVT hull, by contrast, exhibits no discernible planing 'hump'. The vessel can maintain any speed within its performance envelope returning full command to the driver.BDKShttps://www.blogger.com/profile/05241515681262605157noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-67931630359151221302019-04-21T01:27:14.293+02:002019-04-21T01:27:14.293+02:00When gas engines first became common in pleasure b...When gas engines first became common in pleasure boats there were many designs of long narrow boats that got amazing speeds with very little horsepower.<br />Modern designs for very slender vessels also require much less horsepower to attain high speeds.BDKShttps://www.blogger.com/profile/05241515681262605157noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-41948525996599139772011-12-19T14:20:23.614+01:002011-12-19T14:20:23.614+01:00Nice idea, this submersible frigate, it offers the...Nice idea, this submersible frigate, it offers the best low observeability possible.<br />The quoted speed on its own doesn't make sense. For the LCS for example it's known that these ships don't lose much speed when turning. So if you fire a missile on a ship that releases decoys and jams you, you'll need a very wide arc to retarget it after it evaded you through a maneuver. The most likerly reason is that the missile was still locked on the original ship position taken up by a decoy or that the ship followed some airborne decoy moving in a different direction than the originally targeted ship (RN, Falkland War trick). The faster a ship is, the less time it needs to be out of range of missile impact point on which the enemy missile is locked on. The faster it evades this point, the less warning time it needs. That's very sensible if the enemy can fire something very fast from a very short distance. So current naval developments do make sense, but I don't know if increased speed is the best solution to rapidly appearing threats that leave little reaction time.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-10537997464333085882010-10-04T13:42:54.409+02:002010-10-04T13:42:54.409+02:00Para

The low depth and limited speed clearly indicate to me, that this ship is supposed to be a medium sized surface vessel, ie. light frigate, that will operate mainly above the waterline and use its submergingg capability as a means to escape enemy detection or to seek an advantage in a specific tactical situation. Its a frigate with submerging capability, not a coastal submarine that sometimes operates on the surface with extreme speed. I have to see more hard numbers on it, but it also does not strike me as primarily a littoral craft, rather a combined blue-and green water-asset (ie. LCS, any kind of MEKO light frigate).<br /><br />The first thing that came to my mind when I saw this concept was Keegans thesis that pretty much all aspects of naval warfare will move underwater.paranoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-85475480268899339722010-10-02T18:08:55.888+02:002010-10-02T18:08:55.888+02:00Sorry I am taking the speed issue up again but I r...Sorry I am taking the speed issue up again but I remembered a passage I read in Hans Frank's "Deutsche Schnellboote im Einsatz - 1956 bis heute,121 ff.". There is one factor a small cramped boat, a compact crew and just the high speed were quite essential for: motivation. You wrote some time ago that a "Vorpostenboot" like vessel that is simple and slow is not enticing enough for some theorists. But what about enticing its crew? But admittedly I am not shure if the increase of fighting spirit is forth the disadvantages high speed involves.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-71353020296850800682010-09-30T12:59:37.173+02:002010-09-30T12:59:37.173+02:00Im struggling to think what role it would fulfill ...Im struggling to think what role it would fulfill outside of a niche Fast attack craft substitute.Lukanoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-69578460448072921382010-09-30T12:54:46.209+02:002010-09-30T12:54:46.209+02:00Its an interesting concept, one I'm surprised ...Its an interesting concept, one I'm surprised hasnt ever really been done before.

Is it to cruise into your operational area or missile range rather quickly and to make a fast withdrawal after your mission is completed? I always thought the LCS speed requirement was due to small boat interception missions in an asymetric scenario - which you don't seem to be a friend of anyway.Anonymousnoreply@blogger.com
