towed array
 

I was wondering if a sub had it,s towed array deployed,,and an enemy sub is trailing ..would the enemy sub be able to detect that it is deployed? And if there were any collisions with these in real life when one boat would shadow the other?

Enemy sub wouldn't know that a towed array is already deployed. It's a passive sensor so it's not making noises.

A Victor 3 sub has a picture of it getting a US sub towed array fouled on her hull. http://www.subguru.com/multimedia.htm

If the sub was trailing and detected the array being deployed maybe. Not sure how much flow noise the array would make.

For your second question there was a well known incident where a Soviet Victor III the K-324 ran afoul of the Towed Array of a US Spruance class destroyer during a ASW exercise. The TA rapped around the Victor's screw and disabled her, she had to surface and send someone out with an axe to cut it off. She was towed to Cuba for repairs

In 2009 a PLAN sub bumped the Towed Array of the USS John S. McCain.

However do not forget - Victor, has brought with itself a cable and the sensor control towed array from -Sprunce- which has remained on the screw Victor.

Soviets - have received a good technical novelty for study. :DL

PS: And even there were attempts to remove from the screw Victor a cable - American helicopter tried to hook by a hook on a cable :-)

I read that we snagged the cable back. :hmmm:

No worries, a fisherman in Washington snagged a Pelamida in his nets a few years ago.

To your regret - the gauge was not received from the helicopter.
Soviets have received not only a piece wire, but also sensor control (main sensor).


By the way - you probably are informed, that the first samples of Russian wires were very unreliable. There was a bad rubber - which from salty water and low temperatures gave cracks in wire.

The American samples, have given a good direction in this area. :-)

Blind Man's Bluff said otherwise. Wouldn't be the only thing they got wrong in that book.

Yes they cracked if rolled too tight on the spool, that is why the 1st Russian subs with TAs had those big pods. The Oscars, Typhoons, Deltas, One Tango and one Akula were fitted with better arrays with out the pod.

Gepard - there is no large pod.

It speaks that the problem was solved.

The large bobbin any more is not required.


Just as last models Russian Subs -Borey-, -Severodvinsk-.

Anybody any more has no the large pod.

Yea Gepard that was the one with the improved TA.

The Lada class has the improved towed array as well.

Thanks for the correction.:)

I think the electrical signals that go down the array could be detected on LOFAR as well. :hmmm:
