Deorbit complete. We dont build these anymore, so into the attic they go.

-** Klingon Attack Routine
-**
-** This routine performs the Klingon attack provided that
-** (1) Something happened this move (i.e., not free), and
-** (2) You are not cloaked. Note that if you issue the
-** cloak command, you are not considered cloaked until you
-** expend some time.
-**
-** Klingons are permitted to move both before and after the
-** attack. They will tend to move toward you before the
-** attack and away from you after the attack.
-**
-** Under certain conditions you can get a critical hit. This
-** sort of hit damages devices. The probability that a given
-** device is damaged depends on the device. Well protected
-** devices (such as the computer, which is in the core of the
-** ship and has considerable redundancy) almost never get
-** damaged, whereas devices which are exposed (such as the
-** warp engines) or which are particularly delicate (such as
-** the transporter) have a much higher probability of being
-** damaged.
-**
-** The actual amount of damage (i.e., how long it takes to fix
-** it) depends on the amount of the hit and the "damfac[]"
-** entry for the particular device.
-**
-** Casualties can also occur.
