Future of Submarines - ejection capsules possible?

As missile threats from the air, land, and sea increase, navies might become more interested in submarines. However, the downside is that if a submarine gets damaged, the entire crew might be lost. So is it possible for them to be equipped with ejection capsules, similar to ejection seats in fighter jets? This will save a lot of lives if battles become increasingly underwater. Do they have ejection capsules on today's subs? It must be pretty scary to be in a sub when there's a battle going on.

Is there a possibility for light attack submarines, which will be similar to the crew number of a tank (3 or less)? If fitted with stealth technology, these subs might become virtually undetectable, but they will likely not be able to endure long operations like the larger submarines. That's where the submarine replenish ships come in, which will be similar to inflight refueling. Ejection capsules will also likely be more probable in these small subs. Maybe there will be unmanned attack subs, controlled by a ground station, an airplane or a command ship hundreds of miles away via satellite communications.

If the PLA ever wants to have subs in place of aircraft carriers, then they should be thinking about the survival of their crew members when faced with emergency situations underwater.

Coastal defence seems to be much easier accomplished with submarines. Any surface based vessel can best be substituted with land based missile launchers. The newly commissioned FAC seems to be mostly used for amphibious assault (notice the marine camouflage as opposed to navy grey).

Can a moderator rename this thread to "Future Submarines" instead of the current title? I think it's more fitting. Thank you.

Hello Everyone i'm Xenostrike 06 an amateur military spectator from Indonesia,your south east asia neighbor,enough with the introduction let's get on the thread

hmm...ejection capsules,yes it's possible,but i think it should be placed on a larger submarine than the light ones,for them i suggest utilization of "separation of weapons crew compartment" just like Modern MBT today,if the sub get breached the crew may eject by removing their compartment,leaving the weapons bay as a prey for hungry enemy torps,and as for the "stealth attack sub", i don't think it will be "Virtually undetected" as the naval vessel's passive sonar will pick their sonar,they'll be effective if deployed near targeted vessel,or in landing mission,dropped by aircraft,and about replacing aircraft carrier,how about developing "Submarine Aircraft Carrier",a sub capable of performing aircraft carrier's duty :china: ,this sub can hide while infiltrating enemy territory or launching Aircraft underwater (he..he an Underwater Fighter or capsules and water landing gear must be developed first to perform this task)far away from targeted fleet,concealing his location while strike the enemy the aircraft will land on designated sea area then retrieved just like japanese's L-400 sub,that's all
i'm sorry if there's a word or more of mine which is not suitable in this forum and sorry for my poor English

I actually think the idea of "Light Subs" that give large submarines the ability to linger back and strike from multiple directions. The main limitations would be that they could only carry one or two torpedos and that the "motherships" could only carry two or maybe three (the motherships would have to carry fuel and torps for the "fighters") if you want to keep a reasonable size and allow the mothership to have independent combat abilities. However the bonus would be that upon encountering the enemy you could have an instant wolf pack in action and you could attack without giving away the subs position which is the submarines main weakness.

As for escape pods-I like the idea. The only comment I have is that the only really economical way I can think to use them is to place them in the tubes of SSBNs. You could convert a few tubes. Besides would they even work on a sinking submarine that's possibly broken in half, etc?

That capsule idea is difficult, when under attack and finally struck, the subs crew will be on battle station in different parts of the sub. And a brake-up can be pretty fast. So the best solution might be to use mini-subs attached to the main sub to disembarg it under water.

A sub-carrier is pretty difficult. It would have to be pretty big, since it has to carry, fuel ammo and crew of the smaller ones.
I believe UUVs (wich are already studied) are the best option here. You don't need to have crew in them, so they can be rather small. You can assign them certain tasks and they carry torps to a specific attack point and launch them. Or just stalk around, listen and report to the sub.

Hello Everyone i'm Elinge and my duty is projects managing and I've a hobby of construction of submarine models. I belong to a specialized forum about submarines ins spanish language and I read a lot. I'm from Argentina
From my limites backgroun of specialized knowledge about this matter, I think that it's possible to use capsules,but i think it should be placed on a larger SSN or SSBN and not for a light ones like the diesel electric submarines of 1400 - 2000 tons. who are in active service in all the navies with havo no atomic subs.
Its my opinion. The capsule's services, I think that requires installations that only the nuclear subs have.

For all the members of the forum! Please! Excuse me for my English! I just finalize the reading of my post and I think that my English redaction is too bad! I hope all of you can interpretate my words! Thank you!

It's fine, don't worry. Wonderful insight you have. It makes sense for the ejection capsules to be only available for larger submarines, but it might also be possible for light attack subs with a much smaller crew member than currently available.

The Russians have developed ejection capsules for some of their submarine designs. The K-278 Komsomolets had one in the sail, which helped the commanding officer and four others escape the sub, but all but one died while rising to the surface because the capsule was partially flooded with water, and was filled with toxic gases stemming from a fire. The Oscar class submarines are also suspected of having an escape capsule in the sail as well, and the Typhoon class submarines as well.

In the address , we can find out a notice that seven US Navy submarinist practiced locking out from the attack submarine USS Los Angeles (SSN 688) and ascending to the surface wearing special suits that was designed to enable a free ascent from a stricken submarine.
The divers did that on december, 2 of 2006 during ESCAPEX Exercise at the Navy’s Southeast Alaska Acoustic Measurement Facility in Ketchikan, Alaska.
The US Navy’s renewed interest in submarine escape comes as U.S. submarines operate more frequently now in shallow coastal waters, said Submarine Development Squadron (CSDS) 5 Commander Capt. Butch Howard, who oversaw the exercise.

By reading this I asked myself ¿is that method most effective an affordable that the planned capsules one? ¿Or both methods are complementaries: the capsules method is for deep waters and the special suit one is for shallow waters?
