I had an idea one day, found it weird... so I drew it, because why not...
Type: Armed-MLP and tanker
Hull design: heavy lift hull with long and sharp bow for better cutting trough the sea, at speed. Tunnel in aft hull.
Length: 180 meters
Beam: 25+meters (depending on version, designed and build)
Draft: 8.53 meter (submerged: max: 15.5 meters (calm sea: 16.8 meter critical) (deck depth: 3.81 meter, 5 meter at critical depth)
Power-plant: 2 jet turbines and 4 medium and 8 small diesel engines powering generators, for ship electricity and propulsion.
Propulsion: two Azi-pods aft, and one small retractable Azi-pod forward.
Speed: 18 to 20 knots, can move at 2 to 3 knots when submerged (probably not).
Electronics:
Artisan 3D radar
STIR 1.2 EO/STING (fire control)
modified I-MAST fire control (hope it work...)
Various communication equipment and Navigation equipment.
Armament:
- 1 x 5" main gun (AU-guns on drawing), can be replaced with bigger gun if needed. But most ideal would be an SAM installation.
- 2 x twin 40 mm guns (AU-guns on drawing)
- Several handheld and railing mounted guns.
Aircraft facility:
landing deck for medium helicopters.
Deck: can handle most vessels, enough space for ships like the Visby class, Skjold class or similar
