Starting in ye_32 the fourth_fleet began deploying the "Guriddo" Defense System to augment their planetary defenses. During periods of heightened alert status, the grid will be deployed at .5 AU around the planet; all other times it will be deployed at .25 AU.

The deployment contains the following:

• 20 kyouheki each sharing control of two nesuto
  • 10 nesuto each with 18 suzumebachi
    • 180 suzumebachi

Note: Each deployment counts as 20 ships against fleet strength.
