[Build a Submarine That Can Get To Orbit]

I'm not 100% sure this qualifies as I've never submerged it, then went to orbit. My Flying Mantis is a VTOL, SSTO, SeaPlane, and Submersible, but because of the margins you pretty much pick one at takeoff. https://kerbalx.com/sumguy/Flying-Mantis

I'm excited to see where this tech goes

[The K Prize - 100% reusable spaceplane to orbit and back]

I just ran across this challenge, but thought I'd enter one I did as a challenge to myself which I started in v .18 and finally accomplished after many iterations in v.90.

My challenge was take an orange tank into orbit w/o using any of its fuel and return to the ksc landing strip, stock only, no refueling, ssto.

The newly named Constellation, Jumbo SSTO 2 is a spaceplane capable of delivering a 36t untapped orange tank to LKO and returning to the KSC landing strip.

Here's my challenge proof video

Looks like it's up for Advanced Pilot Precision, Utilitarial Commendation, maybe largest ( 28.04 x 7.63 x 26.13, 250 parts ).

Anyway it was a fun challenge, and I'm happy to get to share
