Sonar On USS Becuna

[@stevewindisch7400]

One drunken night a friend of mine, who was a sonar man on a 688 in the mid 70's (Los Angeles class attack sub), told me a story. Technically he was still sworn to secrecy over this incident, but he was very well lubricated at the time and it was many years later. The boat was off the Soviet Pacific coast line, near the port of Vladivostok and the nearby Soviet naval base. They were sent there to get the sonar signature of a new class of Soviet sub... and they were too close, well within Russian territorial waters. And then suddenly, the 688 ran aground. Bow stuck hard on the mud. They tried everything they could think of to do quietly to get off, gently rocking it, slow reverse... No go. Hours went by, a whole day stuck down there. The suction from the mud was too hard to break. The noise they made attracted some patrolling Soviet surface warships, who started active pinging and randomly dropping depth charges. The captain finally decided he had enough of this, and simultaneously blew air out of the forward torpedo tubes while going to flank reverse. They broke free, and got the hell out of there at top speed (which was pretty darned fast, more than was published). They were chased on the surface by the Russians until they got to deep water, where they lost them. My friend said they were lucky a Russian attack sub was not there; it was only destroyers and frigates after them. They didn't get the signature, but they got home ;)

[@adamdubin1276]

Research boat, she had a towed array that we could use either to scan the seafloor or use it to talk with an ASV. One of my professors was doing a shallow seafloor research experiment, they lowered a transducer to the seafloor to get their readings and starting getting a bunch of clicks and booms, thinking that the array was damaged they raised it up only to find that the array was perfectly fine to they lowered it back down and heard the same clicks and booms, so my professor dons his wetsuit and goes for a little swim... when he came back up he was smiling and said that some pistol shrimp where duking it out in not about ten feet from where the array was located...

[@skovner]

I read a story where a sub heard the shrimp noises, and someone on board knew what they were. Had the torpedo tube outer doors opened for a while, then closed, and they had fresh shrimp for several meals.

[@stevewindisch7400]

Pistol Shrimp are amazing. The snap they make with their claw causes bubble cavitation, and the implosion makes a tiny ball-lightening plasma that can give off light. Sonoluminescence is thought by some scientists to be capable of nuclear fusion with temps in the range of 4-6k degrees Kelvin inside the tiny imploding bubble.

My dad was an ensign on the Becuna during the Korean War. He also served on the Nautilus briefly. If he was alive I would send him the link. I'll have to go visit the boat in Philly.

[@jimtownsend7899]

We had a distinct advantage with our passive sonar. Our hydrophones were in the water, but we weren’t! I and my crew were in a US Navy P-3 Orion, usually flying about 300 - 500 feet (depending on weather and how crazy our Patrol Plane Commander was that day. He would also loiter (shut down) the outboard engines and fly on just the 2 inboards to extend our range.) The nice thing about airborne ASW (besides not being a target!) is that we put very little noise into the water. That made it much easier to detect and track the subs. Speed was another advantage. I will vouch that there is nothing quieter than a diesel boat on battery. But we did alright!

[@supergeek1418]

Having served aboard the USS Thomas Edison SSBN 610, yes I've been on a ship with SONAR. As a matter of fact, the Edison was equipped with (among other SONARs) the AN/BQS4 and the AN/BQR2 which appear to be the very SONARs you're sitting in front of! I spent a fair amount of time sitting in front of the BQR2 (and even *more* in front of the BQR7). Great series!

I was on the USS Stonewall Jackson (SSBN634). While not an ST (I was an YN), I did like going into the sonar shack and listening to the BQR-21 to pass the time away. One night while sitting midwatch helmsman/planesman watch, the WLR-9 alarms kept going off. The OOD called into sonar… “Sonar - Conn, report on WLR-9 alarm.” “Conn - Sonar, biologics.” Over the next twenty minutes or so, it kept going off over and over again. Everybody in control… QMOW, DOOW, COW, helmsman and planesman were pretty much ignoring it but not the OOD. He was becoming unglued and was really really agitated by the alarms when suddenly picks up the mic and yells “SONAR - CONN, WHAT IS THE WLR-9!!” In the calmest voice ever, the Sonar Sup replies, “Conn - Sonar, the WLR-9 is an acoustic intercept receiver.” DOH!

@@brianbranson2306 I always thought that the "S" stood for "Sending" and "R" for "Recieving" since the BQS was the active/transmitting part of the pair (with the transmitting transducer located in the middle of the BQR's circular array) and the BQR was the passive (or Receiving) part of the pair. I certainly could be wrong, though. I'm no expert on AN numbers.

Because they are so quiet, almost all submarines have the advantage over even the most advanced surface combatant. The destroyer Caron was trying to detect and track a "cooperative" target submarine, a USN nuke of the (IIRC)Sturgeon class. This guy cut us all kinds of slack including running with about 6 feet or so of periscope showing above the water. He was too quiet for us to hear on the passive bow array and we had no towed sonar array in those days. No problem when we went active with the SQS-53C bow array though. Later, real world we were following carrier Coral Sea as her 'plane guard.' In those days only a few US destroyers had towed array sonar, we could only detect targets or noise sources ahead of us ... and Coral Sea was noisy as a major industrial foundry (so said our sonar techs) so it covered up any other sound sources ahead of us. The carrier had a cruiser, us (Caron) and another destroyer (DDG) plus one of the first Los Angeles class subs as her screen. The 688 found a Soviet Victor II or III class boat following the surface force. Her Captain opted to come to periscope depth, stick up a radio antenna and warn the group. The first inkling the Soviet had that anything was wrong was when the carrier, cruiser and one destroyer accelerated to Flank speed and the Spruance class Caron turned around and began hammering him with active sonar. I don't think he ever knew that he had been initially spotted by another sub.bow

[@phillipbouchard4197]

The U.S. Navy was very interested in the extensive sonar gear and multiple listening posts on the German Heavy Cruiser Prinz Eugen ( I X 300 ) when she was examined at the Boston Navy Yard after the war. While German Naval Radar systems were inferior to our radar system's their sonar was better. Indeed our modern sonar was patterned after the German's. It was reported that during the Denmark Straits battle Prinz Eugen detected Hood and Prince of Wales with her sonar prior to a radar intercept.

The Thomas Edison SSBN 610 was equipped with a depth sounding sonar (the BQN-3) that emitted a "ping" that was designed to sound like biologics. The manual described it as "the sound of cetacean flatulance" A. K. A. whale farts!

[@corkcamden9878]

I was on DEG-3 pre-FFG designation, and the sonarmen on that boat were some sharp cookies! Our main mission was tracking subs as a member of a hunter-killer group. We employed a LAMPS helicopter which operated in conjuction with the sonar guys. The objects those men could identify just boggled my brain! They could, by various means- none of which was I privy to- tell by the sound of the screw, what class sub they were tracking and they could detect many miles off a Soviet or any other navy's sub or surface vessel lighting off, getting underway, and many, many other parameters concerning a particular ship. Like I say, they were incredibly astute sailors and were the bain of every enemy craft which turned a screw anywhere within a couple hundred miles of us. Amazing stuff!

Served on Uss Blenny SS 324 we were developing passive ranging sonar in the late fifties. Hydrophones were housed in three fiberglass shark fin like structures one at the bow one just behind the sail an on the stern. From the time delay that each set of hydrophones picked the signal from the target they could calculate speed course distance.

Except for two things. 1) they need a starting datum point 2) finite number of passive and active buoys. Once an active signal is detected, the sub, at maximum quiet speed just moves away or moves above or below the layer, depending on the estimated depth of the transducer and go to a higher speed.

Conventional submarines have some other major advantages over nuclear for most countries, they are cheaper so you can afford them where nuclear is out of reach for economical reasons. Nuclear technology is also more controlled so there is not multiple countries that are willing to sell them like there are for conventional submarines. India did leas two nuclear submarines from the Soviet Union/Russia. US and UK will cooperate with Australia for nuclear sub-construction but that is if I am not mistaken the only international technology exchange. So counties would need to develop their own reactors and submarines and that costs an enormous amount of money India has recently built their own nuclear submarines but the reaction is if I am not mistaken an Indian design. France is cooperating with Brazin for their nuclear submarines but the reaction is Brazilan, the plans to get nuclear submarines started in the 1970s and is currently under construction. So even if nuclear submarines the best option and you have enough money there might not be any way to get them that does not take decades.

[@wfoj21]

Soryu Class - Japan - became operational around 2010 are Lithium-ion batteries. I did not full search - might be only / Class Nation with Lithium ion batteries . Nuclear Powered submarines - only USA, UK, France, Russia, China, India, and coming in 2030 Australia. - the First 3 listed are Nuclear Submarines only . Side Note sonars - I believe World War II Cruisers generally did NOT have SONAR - Modern Cruiser (Ticonderoga, Leahy, Belknap) have SONAR.

@@wfoj21 yup, only recently has lithium ion batteries has been used due to problems of it heating up. Also, not mentioned are the AIP subs with power provided by fuel cells (German 212 class) or stirling engines (Swedish Gotland class). Extends the range from days to weeks but is expensive and speed is still far less than on a nuke boat.

they were not the fist smart cars, yes they were electric but they had electric cars since at least the 1920's and electric locomotives since eddison built one to move about the generating stations when he built them to start electrofying the cities of the east coast. if not earier then that

[@ghost307]

The fist electric car came out in the mid 1800's...and they're still impractical for most drivers. Electric locomotives...1834.

@@ghost307 thank you, though I do know at least of edison having one of the first electric railroads on a large scale, and them using electrics to come into the nations capital to cut down on smoke very early on

@@manga12 Edison was best at self-promotion...and not much else. His locomotive came out in 1880. They started running in Scotland in 1837. If Edison invented anything that is still popular today it's called market research. He did research to see what people would buy and used that to give the marching orders as to what to work on. If he found that there was no market for something he didn't spend any resources pursuing it.

Ryan, I love your work. You are too educated to keep mispronouncing “nuclear.”

[@LexieAssassin]

IDK about modern boats, but definitely boats of the era of Becuna have to keep water flowing over the dive planes in order to maintain depth. So, completely stopping is out of the question unless surfaced.

[@supergeek1418]

Not true. Water can easily be pumped to and from trim tanks to maintain neutral buoyancy. SSBNs actually have a pair of trim tanks amidships called "hover tanks", one of which can be pressurized, and the other vented to inside air. A joystick on the BCP (Ballast Control Panel) allows nearly instantaneous blowing or flooding to or from sea and either hov-1 or hov÷2 (depending on which was pressurized or vented).. Granted, most boats tend to operate at slightly negative buoyancy, and use the lift generated by the diving planes to maintain precise depth control, but they can all be trimmed to neutral buoyancy by pumping to and from trim tanks.

[@LexieAssassin]

Notice I said boats of THAT ERA. Imagine trying to trim the ballast tanks by turning a myriad of hand operated valves. It's not something I imagine would be worth the effort required. I'm vaguely aware modern subs like SSBNs can hover. This is one of the chief things that enables submerged vertical launches.

[@supergeek1418]

@@LexieAssassin When I was in (late 60s/early 70s) the diesel boats that I helped work on had electrically operated Vickers valves for trim control. Definitely not true hover, but not totally manual, either.

[@LexieAssassin]

I'm admittedly less familiar with US fleet boats, but AFAIK, all the German WWII era subs all used hand operated valves. Near as I'm aware, that was what all boats of that era used, but I could be wrong.

[@supergeek1418]

@@LexieAssassin I think that the changeover to Vickers valves was part of the Guppy conversion.

Does that make you feel better about yourself? A little advice-do not try to parade your "superior knowledge" by correcting pronunciation of any word. There is an entire world out there and they pronounce words differently in different places. Not only are you likely to be wrong, you risk looking like you do now-like an ass.

[@akefayamenay104]

@@ianbutler1983 My comment was not unkind. I would want others to let me know if I was mispronouncing a word just as I would want them to let me know if my fly was open or there was a booger hanging out of my nose. It’s not "superior knowledge", it’s just an awareness that comes of doing a lot of proofreading. Grammatically, the word nuclear is supposed to be pronounced a particular way. Look it up in a dictionary. As for looking like an ass, who is more asinine: someone who suggests a correction or someone who refuses to do a basic sanity check before making a personal attack on the character of someone they’ve never met?
