Thanks Unseen. We need people to help us fill in the blanks.

Observe. In this blowup, what are the canister looking things on the sloping part of the outer hull?

**greenman407** · 10-03-2012, 06:50 AM

Since you all were stumped on that one heres a chance to redeem yourselves. What in the blue blazes is this?

Sound-survey rig?

Used to identify and analyze self-noise sources.

Nope, but your close.

Bow sonar calibration rig?

**greenman407** · 10-04-2012, 06:52 AM

Absolutely! Give that man a Teddy bear! The first three pictures are of a delta named Novomoskovsk. It is described as "udochka" which literally means (fishing rod). It calibrates sonar based on bearing angle. The fourth picture is taken from the stern area of a Borei. The fifth picture is of one of the new Garaney class boats and the last one is back to the novomoskovsk.

Good catch, Romel!

This is the Marlin. Ive zoomed in on a small door on the bow. Looks too small to be a torp tube and this is a research sub. So, what is it?

**He Who Shall Not Be Named** · 10-09-2012, 01:33 PM

Torpedo tube shutter-door (or fairing to keep the birds out). The two T-boats had a single tube for launching 'targets' and Mk 37's. Both of which were 'swim-out' launched fish. I don't remember if the tube was rigged for pneumatic ejection. I was on board one once and I think it had the same MK33 tube we had in theTRUTTA's bow and stern nests.

Well that answers that. Your the man who would know.

**Von Hilde** · 10-10-2012, 12:03 PM

we called those boats the M&Ms, when I was going thru the Advanced Underwater Swimmers School, in 1962, here in Key West. We used the Marlin and Mackrael in the course of some of our training, back then. They were also used for training by the Fleet Sonar school as well. The first sub I ever saw out of the water was one of the two, but I cant remember which one.
