                             Concept : Ship Types

 The ships currently available in Empire are:

   patrol boat         submarine          oil derrick
   fishing boat        tanker             aircraft carrier
   minesweep           heavy cruiser      battleship
   destroyer           cargo ship         fishing trawler
   landing ship        nuclear sub        nuclear cruiser
   nuclear battleship  nuclear carrier    cruise ship

These ship types differ in their fundamental capabilities; some can  fire  two
guns,  some only one; most require petrol (if the game is configured with such
a requirement), while more advanced ships are nuclear powered.  The  sizes  of
guns  may  differ,  and although cargo ships can carry many guns it can't fire
them.  The capabilities of each ship are given by the show command.  The head-
ings are as follows. For the building data:

 lcm  The lcm required to build the ship.
 hcm  The hcm required to build the ship.

                             Concept : Ship Types

tech  The minimum technology required to build the ship.
   $  The cost of the ship.

The headings for the capability listing are

def  defensive armament of the ship
spd  the distance/mu for moving (in relative units)
vis  how visible the ship is, (relative units)
spy  how far the ship can see, (i.e. how good the communication equipment is),
     again in relative units
rng  twice the distance the guns can fire, (assuming a high technology level)
fir  the number of guns the ship can fire at once

Ships are built, scrapped, and upgraded in harbors.  Each  ship  can  carry  a
certain  amount  of  products  and  has certain capabilities. These are listed
under the cargoes & abilities section.  The cargoes give the  number  of  each
product that can be carried.  The abilities are as follows.

                             Concept : Ship Types

 fish  The vessel will accumulate food by fishing
 torp  The vessel can fire torpedos.
dchrg  The vessel can drop depth charges
plane  The vessel can carry planes with the light attribute set.
 miss  The vessel can carry missiles.
  oil  The vessel can drill for oil
sonar  The vessel has sonar capabilities to detect submarines
 mine  The vessel can lay mines
sweep  The vessel can sweep the sector for mines and recover them
  sub  The vessel is a submarine
  spy  The vessel can engage in spying activities
 land  The vessel can be used as a landing craft
  pet  The vessel requires petrol as fuel.
trans  The vessel can be used to transport land vehicles.
