Abstract
A laser-powered ice-penetrating communications payload delivery vehicle for sub-ice submarine missions enables under-ice operations to exchange information with terrestrial facilities or satellite networks with communications methods otherwise blocked by an ice cap. The vehicle comprises an electronics bay, a payload bay, optics bay, and a melt optic with laser. The system and method of establishing communication where the vehicle, tethered to a sub-ice vessel, is released. The vehicle ascends to the bottom of an ice sheet and uses a laser to melt the ice, forming a borehole through which the vehicle continues to ascend. When buoyancy no longer advances the vehicle beyond sea level, the vehicle continues to melt a conical opening through the ice until unobstructed atmosphere is reached and bi-directional communication is established. Where the melting capacity cannot reach ice to continue melting, the vehicle mechanically advances itself toward the surface to establish high bandwidth, bi-directional communication.
