Ripple's Sea Serpent rocket class is mobile, reusable and scalable enabling a cost effective rocket which can be integrated into the global logistical network and provide payloads of varying sizes and mission profiles to customers. Designed to be built in shipyards to utilize maritime manufacturing processes, Sea Serpent rockets will be massed produced to empower customers the ability to gain access to launch systems by means of Ripple's launch provider services or direct rocket ownership.
It never occurred to me to have the SLBMs without the submarines, until now. Sea Launched Ballistic Missiles. But it makes perfect sense. Drop an ICBM in a tube into the deep ocean; when activated it rises to launch depth and fires. It's so obvious, I wonder why I've never read even a whisper about a concept like this…The "Sea Serpent" stats say 2.6 metric tons into LEO. Correct me if I'm wrong, but isn't that in the same neighborhood as Trident II payload? This is a pretty great concept, not least because you don't need a launch facility and can launch from almost anywhere, to anywhere, with maximum efficiency.
This "giant torpedo" was a WWII unbuilt German design to hold a sea launched V2 #rocket. Note the small crewman near the bottom.

Being able to launch in international waters doesn't hurt, either.
Navies build ICBM subs because they are very difficult to detect.The actual benefits of ocean launch for a space launch system are1) Use an ocean going tug to tow it, rather than a ship to carry it.2) In principle vehicle size is set by size of a ship yard you can build it in.
Once you put the ICBM in a pod it's much less mobile and hence much more easy to find
And you can launch from the equator, or wherever else you like, and get as much Atlantic/Pacific/Indian Ocean as you want to land stages in.
QuoteOnce you put the ICBM in a pod it's much less mobile and hence much more easy to findHow so (genuinely curious)?
Revision 2.0, put a camouflaged portable "silo" on the sea floor. Orient it horizontally for better camouflage. The tube pops out horizontally and rises to launch depth, then the rocket is launched.
Edit:Course now I'm wondering how to communicate with the weapon to tell it to fire...I know I've wondered about undersea communications before, and either didn't get very far last time I looked at it, or forgot the details...
How are you moving this pod? Either you've got a sea going (surface) tug, which means you can be tracked on satellite, or you have a "sub tug" which don't actually exist outside of Frank Herberts novel "The Dragon in the Sea."
Rather than ICBMs, 'Sea Serpent' is a not-so-subtle allusion to the 'Sea Dragon' superheavy lift concept, which uses the same partially-immersed rollout and launch sequence, and even the distinctive 'stick out' engines partway up the stage.

I'm not a conspiracy nut, but this is the kind of thing that gets you disappeared by the DoD.
Because it is a terrible idea for all the reasons mentioned.
The question of wheather you can fire a rocket under water was answered by (IIRC) Aerojet with test firing off the Californian coast of an Aerobee sounding rocket they called the "Seabee." IIRC the start up was reported as quite smooth, partly because of the sea water in the combustion chamber. It was held vertical by a "sinker" chain which separated just before ignition.

Or use a drone to send it well away from the sub before firing.I'm not a conspiracy nut, but this is the kind of thing that gets you disappeared by the DoD.
