USS Boise (SSN 764) surfaced through ice in November 2006. Polynya was circular, about 500 yds diameter. Temperature was -7 degrees F, time 1200 UTC.
Зачотное фото. А Русские подлодки могут стрелять из подледного состояния! Бугога!!
what could you say about this picture. how it was taken ?
Victor: Submarines configured for sailing under ice, are usually equipped with a vertical upright looking light sensitive camera. The americans calls this a Submarine Remote Video System (SRVS) and the british call it a Polynyas Upward-looking Camera (or something like that, i can'r remember the precise terms, but they shouldn't be to difficult to google). This cameras - combined with ice-sonars - are used to find the thin spots of ice, so that the damage on the submarine, while breaking the ice, can be kept to a minimum or prefferebly totally avoided. These cameras can probably be configured to create stills as well.
Cool. How do they get through the ice? They "crash through"?
D.C.: Yeps. That's why they look for the thin ice :)
It should be a rather impressive sight (from above) and a similar terrifying experince, from inside the sub the first time (because of the noice) :D
Vov, beautifull picture!!!
To surface through the ice the sub first achieves a zero bubble, zero knot trim (stop the boat under the ice with the displaced seawater equal to the weight of the ship so that the ship neither floats up or sinks). Then pump about 4000 lbs of water from forward to aft tilting the boat up about 4 degrees. Then gradually "blow" off water until the ship achieves 0.5 feet/sec upward vertical velocity at ice impact. 6900 tons of submarine is now coming up through the ice with all force being applied to the very front top of the sail. I was the DOOW (diving officer of the watch) during the surface and heard nothing at impact, though I did hear the ice slide off the top of the sail as it came further through the ice.
I didn't understand one thing. Couldn't this photograph just been taken by a common Digital Camera?
