Torpedoes can be seen inside.

Underwater fighter design. This is a craft that can be released from a submarine mothership in order to do battle at close range. Inspired by japanese midget submarines from 1945.
Armament is based on a rotary eight-tube torpedo launcher device.
Propulsion in by Walter turbine using Hydrogen Peroxide as an anaerobic source of steam power.
Crew is an Ultraman that has not the physical limitations of ordinary man.

I'm trying to describe theinternal singularity ofthis aircraft. You ca see two different gas jets coming down from the vehicle: a hot exhast gas coming from the turboshaft and a cold air mass coming from the mechanical fan (between the open doors).
A variable clutch allow select the power available to lift fan and rear propeller (for forward flight).

Two units flying in formation over the sea. Note that there is not a human pilot inside the cabin. Unorthodox air machines need unorthodox pilots.

The same, in U.S. Navy service.
