Torpedoes Jump Waves?

Delgard · 07-16-17, 10:28 AM

I just noticed this morning that a torpedo seemed to make detection, run near the surface and disappear for a second or two. I came back visual in a downward angle, reaquired, and headed to the target. It was a Mk-48.

Was it just playing with the porpoises? Just a new thing for me.

Any thoughts

I notice this behavior also a long time ago. A MK-48 will not do this...

a 688 Class (Los Angeles) that has Mk-48 torpedoes. The FLT II (2) version was a step-up from the original.

Sometimes the U.S. gives a designator to subs built in the class but had added features. Sometimes the word "Block" as in Block II is used. I am not sure the difference in the use of the two words.

The Flight II version is just the upgraded version, that's all. You really have to look at the specifications of both to see the differences. The Flight II has Mk-48 torpedoes, though. I didn't remember, but the sea state may have influenced a torpedo running close to the surface, on final approach to the target and at 15ish feet. Maybe just a deep swell.

There were FOUR distinct flights of 688. (Wikipedia is incorrect)

Flight 1 - 688-699 (upgraded to flight 2 specs at first DMP)
Flight 2 - 700-718
Flight 3 - 719-750 (First VLS)
Flight 4 - 751-773 (also called 688I)

I would like to know where you get the 15ft. depth for the MK-48?
This is incorrect.

I served on SSN-702, SSN-670 and SSN-723 as an FT.
