And here are the stats the Casual Observer made for the design back in the day:

Total: 1 unit, +1 ordered. Also based on the Spearhead design, the Callsign is a C&C ship whose sole purpose is to remain outside the battle zone as a communications ship. It can also offer coordination and location of ships, friend or foe, during battle to ship captains. She carries no guns or embarked craft as the communications gear takes all the ships room and power. Must rely on frigates and corvettes for protection. The class is the Callsign with 1 other unnamed ship ordered for construction. **Note: purple stripes indicate non-combatant C&C ship, differing from a combatant C&C ship**
