During the fifties the Soviet navy was the growing threat to world peace. They were rapidly building subs that could stay under longer and move faster and more silent than before. Nuclear propulsion plants added to the speed, depth and maneuverability of subs. New weapons were needed and ASROC was the best one developed for this threat. It was a stand off weapon. Could be fired at a distance and used both depth charge and torpedo. Even in todays navy it is the most effective ASW weapon available. Many Gearings were equipped with ASROC for FRAM I conversion. In 1964 when New completed the conversion it came from the shipyards a modern and deadly weapon that could most effectively detect, track and kill an enemy sub target. CIC and Sonar worked closely to track course and speed of the target and maintain a position and up to the second information was relayed to Bridge and ASW offcer.It then became as it always was, a battle of wits between sub and destroyer commanders, who could out maneuver the other and make the kill. ASROC and the other ASW weapons such as DASH and the modern Mk 32 triple tube torpedo mounts helped give us the advantage. ASROC was then and is today one hell of a weapon.
Below are a few pictures. Some from the New. Test firing was done on the Higbee, DD 806. If I can find more from New I would love to have them for this page.
ASROC and the other ASW weaponry New was given would make them as deadly to the newer nuclear boats as they were during WW II. This section gives an overview of ASW weapons thru the years.From the depth charge to ASROC. DASH is included on another page.

Close on the heels of a $5.8M contract modification, Raytheon Co. received a $260M contract modification to the Mk. 15 Phalanx Close-In-Weapon System (CIWS) Program. This modification entails Block 1B upgrades and conversions, system overhauls, and associated hardware.
Phalanx Block 1B CIWS weapon systems are installed on a wide array of Navy ships, even as previous Phalanx versions receive upgrades to add its new capabilities. They are also being installed as land-based systemsõ?Ư

The recent attack on the US Navy by pirates (successfully fought off, thank goodness) already had me thinking about the latest version of the Phalanx Close In Weapons System (CIWS), and when a commenter at Hell in a Handbasket wondered about the capability of the CIWS to engage surface targets, I decided to do a quick post on the subject.
CIWS, of course was originally designed to defend our ships from high-speed missiles. The six-barrelled 20mm gun is a last-***ch defense against incoming ship killers. Over the years, the original Block 0 models (introduced in 1980) were supplanted by the Block 1(1988) and 1A (1996). Now, the Block 1B (also referred to as ?oPhalanx Surface Mode? or PSUM) improves on these, and (maybe more importantly) provides for defense against surface targets like small boats and personal watercraft as well as against slower aircraft like helicopters. Forward-Looking IR and video tracking/targeting, Ku-band radar, and longer barrels providing better accuracy are among the most notable improvements over earlier versions. Capability against missiles is unimpeded. Let?Ts hope that maintenance and combat readiness, long a problem with these units, also improves.
Although it might seem that these improvements might be a response to the suicide attack against USS Cole in 2000, that isn?Tt the case. Prototypes were tested in 1999 and installation of Block 1B systems, either upgrades of earlier versions or new builds, has been going on since 2000.
For more background information on the Phalanx, see (of all places) the Pakistan Military Consortium.

The C-RAM uses a Block 1B, as you can tell by the FLIR and video gear on the left-hand (far) side of the â?oR2-D2â? dome. Iâ?Tve had no word on the the C-RAM since its deployment to the Sand Box last summer. I know for a fact that the military is trying to keep a lid on the actual performance of this beast, so maybe thatâ?Ts why. Defense Industry Daily noted last fall that Northrup Grumman won a contract for more of the systems, so decision-makers must be optimistic of the C-RAMâ?Ts potential regardless of current success.
Also, in my earlier article I wrote that the C-RAMâ?Ts HEIT-SD (High-Explosive Incendiary Tracer, Self-Destruct) ammunition â?oexplode in mid-air, raining shrapnel at the incoming rounds in order to destroy or deflect themâ?, which isnâ?Tt the case. The self-destruct feature is really intended to prevent the rounds from falling into friendly areas on the ground and causing damage. At up to 4,500 rounds per minute, that would be some seriously un-friendly fire raining down and would not win many hearts and minds.
Ship-borne Phalanx systems used to use depleted uranium rounds, but more recently have switched to tungsten. So, fish, keep your heads down!
(NOTE: There seems to be a lot of confusion about the â?oBlock 1Bâ? designation which apparently stems from the naming convention of the Block 1 series. Incremental improvements to Block 1 were â?oBlock 1 Baselevel 0â?, â?oBlock 1 Baselevel 1â?, and â?oBlock 1 Baselevel 2â?. These were replaced by the â?oBlock 1Aâ?, which is being supplanted by the â?oBlock 1Bâ? which this post primarily deals with. Look on the Phalanx family slide above and you will see that the Block 1 baselevels are marked â?oBlock 1 B/L 0â? and so on, and I think this has some folks thinking that it means â?oBlock 1 Bâ?. It doesnâ?Tt.)
