Cloak

Many ships can hide using a cloaking device built into their space frame. Cloaked ships do not show up on
enemy scanners and are protected from enemy attack. The cloaking device sometimes fails, the failure rate in dependent on the failure rate set by the host. The default failure rate is 0%. Cloaking burns at least 5kt of fuel a turn. The ship might burn more than 5kt of fuel if its hull mass is over 100kt.  If a ship does not have enough fuel to remain cloaked it will come out of cloak and burn no fuel.

Under HOST.EXE version 3.20 cloaked ships can attack their primary enemy.

There are cloaking ship counter measures that can be used to stop cloaked ship. Cloaked ship can be destroyed by
minefields. Ships can be stopped and drained of fuel by web minefields. The tachyon beam emitting Loki Class Destroyer will force most cloaked ships within 10LY of it (before and after movement) to become visible to all ships in the area. The D19B and the Saber class starships have a Glory Device that can be set to explode when a enemy cloaked enemy ship is detected.

A Birdmen ship performing a Super Spy mission are cloaked. Their is a danger that an enemy planet will detect the
cloaked super spying ship and fire an Ion Pulse that will decloak all cloaked ships in orbit.
Ion Storms will cause any cloaked ship in them to decloak.
Cloaked ships will not attack planets.
Cloaked ships can attack primary enemy ships while cloaked.
If a ship is damaged it might be unabled to cloak, this is the Damage That Prevents Cloak level that is set by the host.
