This is a weekly posting with GURPS vehicles (and the like) to the
GURPSnet mailing list. I grant the permission for all non-commercial
redistribution of my work, but I would like to know if you put it on
a website or the like. The files at omeyer.gmxhome.de are down until
I fix the automatic PDF generation, which should be one of these
days - see sourceforge.net/projects/gurpsml

Subcarrier Fighter v1.0 (TL6)
Copyright 2010 by Onno Meyer
There are good reasons why submersible aircraft carriers never became
practical, and the design compromises for the fighters are just some of
them. For pulp action heroes and villains, things look differently.
This fighter compares well to historical 1920s or early 1930s models,
but by the start of WWII it would have been outclassed by contemporary
land-based fighters. It is armed with twin 25mm cannon, and optionally
one 500-lb. bomb on the centerline hardpoint, but one burst from a LMG
would rip it apart. The operational radius is perhaps 300 miles.
At 205 mph routine speed, the engine burns 30 gallons of aviation gas
per hour. A full load of fuel and 25mm ammunition is $228.
Subassemblies: Body +3, three retractable wheels -1, two STOL Wings +1.
Powertrain: 500-kW aerial propeller; 500-kW turbocharged HP gasoline
engine; 640-kWs lead-acid battery.
Fuel: 120 gallons aviation gas (fire on 13).
