Battleships were resistant to ton-class shells hitting them. A ship with foot-thick armor would not be damaged by a light-weight drone if it hit the armor. You would still need something like a double hull with the space filled with styrofoam to resist torpedoes. Such a ship could maybe get away without point defense, such as is used on modern ships, because it would just ignore drone hits. Not certain how useful such a ship would be, but there is no way a small drone is going to do serious damage by hitting a foot of armor.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt'>Keith<o:p></o:p></span></p></div><p class=MsoNormal><br clear=all><o:p></o:p></p></div><div><div><p class=MsoNormal>Best wishes,<br><br>Keith<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sure Keith, but there would be no need for all that mass and size, when the idea is to launch drones at enemy surface ships. I have noticed that in the video released of the recent naval battles, the intercepting item is not moving all that fast. Clearly it isn’t a projectile or even a rocket. It is likely a propeller-driven drone. Those don’t cost much, but they are raising hell. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Apparently the Iranians don’t have an effective anti-drone system analogous to our Phalanx radar-guided gatling gun:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><a href="https://www.youtube.com/watch?v=V5DU-uoLwj4">https://www.youtube.com/watch?v=V5DU-uoLwj4</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>spike<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p></div><div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><p class=MsoNormal><o:p> </o:p></p></blockquote></div></div></body></html>
