The Snorting Kilo - some basic tests

Stewy1 · 04-10-20, 04:47 AM

G'day guys,

I did some (very basic) tests with the Kilo and snorkelling (sorry, I say 'snorting').

A Kilo 877, while snorting, will be detected by:

* a Flt 1 LA SSN at 31.2 NM
* a Perry Class Frigate @ 5 kts (no EMCON) at 24 NM
* a Perry Class Frigate @ 5 kts (EMCON) at 28.5 NM (I thought these numbers would be flipped!)

Therefore, if a Kilo Captain was in the combat area, and needed to get to a 'safe' place to snort/snorkel (say, 40NM from the area of likely submarines - in open ocean), it would take 10 hours @ 4 kts and expend 15% of battery charge to get there).

Just some food for thought; I know most people don't play long Kilo missions

Cool!

So what do you mean by EMCON here (I know it means emissions control)? Active sonar? Radar? I'd also be curious to see how well sonobuoys detect it, but if I remember correctly, they have a 7 or 10 nmi hard limit on detection that I'm sure the Kilo would satisfy.

Just some FYI, the only downside to running a Prairie/Masker on a diesel boat is that it raises the temperature in the engine room by about 15 degrees F.

That and the little pin holes in the screw and hull are a pain to keep clean.

Carry on.

Thanks, Chazly - Yes, EMCON was no active sonar/radar transmission, No Emcon was transmitting - It was just through the mission editor, so I think it's 'all or nothing', with regards to Active Sonar and Surface Search Radar...

I tried the same test with some aircraft, I don't think the Surface Search Radar works at picking up snorkels in RA; I believe it can in real life.

Counter-detected by Seahawk - 1.2 NM (flying directly over me; this must have been either visual or MAD detection)

Counter-detected by Orion - 2.1 NM (this must have been either visual or MAD too)

Thanks ET2SN - very interesting! I had to look up Prairie/Masker, interesting stuff!

Cheers guys,
Stew
