I was assigned to a project group in the Navy that had the first operational towed array system installed. At the time it was called "Interim Towed Array Surveillance System" (ITASS) and the first ship to receive the equipment was the USS Van Voorhis, followed by two other DE's of the same class. This was back in 1970. The system has evolved and has been improved and is now standard equipment on most Navy combat vessels and subs. It's one of several methods for detecting and locating surface ships and submarines. There are others currently deployed and being developed. Blue/Green laser technology continues to be explored for sub detection and communication purposes. Don't forget the P-3's and their replacements. My niece is now piloting 'test bed' P-3's, and the stuff is so classified she won't even tell her dad what it's about. I recently read that the P-8A Poseidon (replacement for the P3 Orion) is having a few teething problems with some of it's systems. Once they get them sorted out it should be a very capable ASW platform. |

Carriers don't get anywhere near within range of truck mounted missiles and even if they did and were hit the damage would be minimal. I agree ... a sustained attack of much more potent, long range missiles, especially if nuclear armed, would be a serious threat but the task forces that accompany the carriers are well equipped with defensive systems. Nothing is foolproof but a carrier isn't that easy to sink .. or even render totally inoperable. |

If we've learned anything since 9-11, it should be that there is no such thing as a target that is invulnerable. There are hundreds of missile variations held by dozens of countries around the world, and some are guidable with heavy payload capabilities. -- Proud to be a Liberal. |
