From the German U212 lecture I am researching:

I wish we had this in the U.S. Navy when I was active.  This is a submarine launched anti-air and anti-surface missile.  Helos are no longer a problem.

It has its roots in the POLYPHEM-program, wich even included vehicle launched version for the Army in the early 2000. Started out as a trinational Program, which fell apart after the french and the Italians got out of it. Cheers Alex

All you need to do is make the helo pilots believe you have them. See how long they dip on you then.

I want to shoot down all those pesky Tu-95s

Meanwhile in Russia: "Da comrade this system expensive and complicated, just use MANPADS, problem is solve!"

Alexander

Super complex cutting edge solutions to a Problem!!! It's German what else could to expect

Mark Keogh

It's still only really effective against single helos, and probably not planes. How about a 533mm diameter wire-guided UUV holding 2 or 4 Stingers that runs out away from sub then deploys a launch unit that floats vertically with a sensor above the waterline; you want a bubble of airspace denied to aircaft who must avoid it in case of MANPADs, but the sub might be *anywhere* within several thousand yards of that threat zone. Forcing them to disengage is the key!

Mark Keogh

Except they have to surface to launch. The Igla seems more for instances in which a sub is caught by surprise on the surface...

Seahour

This is brilliant, can you say if we (US) have something like this now?

Alexander

I can't think of many scenarios in wich a modern Sub could be surprised while on the surface. Anyway the anti Helo option is actually only one of the intended missions. The POLYPHEM and now IDAS are planed as a multi purpose weapon against Land and Surface targets too. Wich seems a bit dubious considering a Range of 60 km and a puny 25kg warhead. So the Helo Killer misson looks most realistic to me. To your Point about an appropriate distance to the Sub, IDAS can be maneuvered while still under weather. Wich allows to disguise the actual Launchpoint.

Alexander Vatter-Riemke: aren't PGMs tending to become smaller and used in larger numbers? Think of a swarm of tiny TLAMs, but four times as numerous.

Alexander

Hallo BG213, yes I agree there is a trend thoughts small lightweight systems GBU-39, Brimstone or Sea Venom coming to mind. And a lot of nations are working on what I would call swarm capable systems, but in my opinion this is more in regards of drone technology. Swarm capable missiles are nothing new just look at the SS-N-19 for exampel. In the case of the IDAS I think it boils down to a point of marketing, as I wrote before the Helo Killer misson looks most realistic and so they sell it as the main Mission. Despite the theoretical possibility of carring a max load of 52 missiles, IDAS can't be used in a swarm scenario simply because the way it's guided. A long awnser to your short qustion but hopefully usefull. Cheers Alex

such an "AA mine" might not be intelligent enough to differ between allied and enemy planes.
