.TH Concept "Ship Types"
The ships currently available in Empire are:
.s3
.NF +8
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 \*Qshow\*U command.
The headings are as follows. For the building data:
.s3
.in \w'tech\0\0'u
.L lcm
The lcm required to build the ship.
.L hcm
The hcm required to build the ship.
.L tech
The minimum technology required to build the ship.
.L $
The cost of the ship.
.in \\n(in
.s1
The headings for the capability listing are
.s1
.in \w'fir\0\0'u
.L def
defensive armament of the ship
.L spd
the distance/mu for moving (in relative units)
.L vis
how visible the ship is, (relative units)
.L spy
how far the ship can see, (i.e. how good the
communication equipment is), again in relative units
.L rng
twice the distance the guns can fire,
(assuming a high technology level)
.L fir
the number of guns the ship can fire at once
.in
.s3
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.
.s1
.in \w'sonar\0\0'u
.L fish
The vessel will accumulate food by fishing
.L torp
The vessel can fire torpedos.
.L dchrg
The vessel can drop depth charges
.L plane
The vessel can carry planes with the light attribute set.
.L miss
The vessel can carry missiles.
.L oil
The vessel can drill for oil
.L sonar
The vessel has sonar capabilities to detect submarines
.L mine
The vessel can lay mines
.L sweep
The vessel can sweep the sector for mines and recover them
.L sub
The vessel is a submarine
.L spy
The vessel can engage in spying activities
.L land
The vessel can be used as a landing craft
.L pet
The vessel requires petrol as fuel.
.L trans
The vessel can be used to transport land vehicles.
