The TTs are on the sides, and there are no reloads.
Ships are carrying a small 5t wireless - enough for short range communication. The squadron flagship has a 10t wireless set at the expense of 4 torpedoes. A mixed coal-firing version is available, with 75% coal firing, this version has 2100@12/3200@10kts range.

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 212,7%
      - Above water (accommodation/working, high = better): 108,7%
   Waterplane Area: 3.944 Square feet or 366 Square metres
   Displacement factor (Displacement / loading): 22%
   Structure weight / hull surface area: 23 lbs/sq ft or 115 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,52
      - Longitudinal: 2,31
      - Overall: 0,60
   Hull space for machinery, storage, compartmentation is extremely poor
   Room for accommodation and workspaces is adequate
