                              Command : UPGRADE

NAME
   upgrade - Update the tech of a ship/unit/plane to the current tech level

Level: Expert

SYNTAX
   [##:##]% upgrade <s|l|p> <ships|land units|planes>

The upgrade command allows a country to set the tech level of  its  ships/land
units/planes to the country's current tech level.

Each ship/land unit/plane to be upgraded must  be  in  one  of  the  country's
harbors/headquarteres/airports  that  is  at  least  60%  efficient and has an
available workforce of at least half the size  it  would  take  to  build  the
ship/land  unit/plane  from  scratch.   To be upgraded, a ship/land unit/plane
must be at least 60% efficient.

Refitting a ship/land unit/plane costs half as much as building a new one from
scratch and reduces the efficiency of the ship/land unit/plane by 35%.
