Submarine-Launched Ship-To-Air Missiles

It depend, if the submarine has no weapons to defend itself then sure it is the prey. But if it carry SAM then the submarine would be a lot more dangerous to the helicopter than the helicopter is dangerous to the submarine. A Mica missile will reach the helicopter at much faster rate than a small MK54 torpedo can reach the submarine

But the helicopter does not act alone, and the submarine does. The main mission of the helicopter is to detect the submarine and if it can, attack it, but the rest of the weapon system, destroyers, frigates, even aircraft carriers also have long-range anti-submarine weapons that only need to know the position of the target to act.

Destroyers and frigates doesn’t really have long range anti submarine weapons. Take for example: typical destroyer such as Arleigh Burke class only carry following anti submarine weapons:
Light weight torpedo: Mark 46 , Mark 50, Mark 54 torpedo ( not a single one of them can go further than 15 km)

Rocket assissted torpedo: RUM-139 VL-ASROC (this one can’t go further than 22 km).

That is well within the range of anti ship missile on submarine. If any destroyer or frigate get close enough to use their anti submarine weapons then they are probably already submarine’s food.

Long range anti submarine weapons on aircraft carrrier are their anti submarine helicopter and fighter jet. Helicopter are vulnerable to SAM while fighter jet can’t even carry torpedo. The only kind of anti submarine weapons these F-18 can carry are the quick strike bottom mines. If these submarine move even as little as 30-40 meters aways, these mine are kinda useless

That Time Russia Wanted Own IDAS Missile Analog For Submarines, and How the Project Ended

"Simultaneously with the evolution of anti-submarine helicopters, nations across the world, including the USSR and later the russian federation, were actively invested in the development of countermeasures. But in russia, this effort came down to not just a few failed projects but became a whole chronicle of conceptual degradation that is worth a closer look into."

The russians' attempts to create their own air defense missile for submarines like the German IDAS represent a true chronicle of degradation

That actually makes sense for the Soviet/Russian side. All their small SAMs are command guided, so they can't just make a "SLAMRAAM". The better option for them would have been starting from their MANPADS, like the UK did with Blowpipe.

Sometimes you can hear those splash, if it is a calm day.

If the aircraft is at relatively low altitude, you'll hear it. (For example, a P-3 has a 68hz tonal)

To be fair, now that I think about it, wouldn’t group of small drones with magnetic anomaly detector or LIDAR sensor find a submarine quicker than sonobouys?

 

[Ronny]

3rd Convergence Zone contacts IIRC are not an accurate enough bearing to send AShMs towards, you'd work closer to get a better course track on them. Even if the missiles have the range to get there, a submarine's primary sensors don't have the sensitivity to pull that off.

Isn’t there some submarine with sonar range on order of thounsand km?
