This is the text I'm seeing:
Mark 1 Munitions booster: Attack Boost for Allied Ships (5000 range, +-21% Bonus)
Mark 2 Munitions booster: Attack Boost for Allied Ships (6000 range, +9% Bonus)
Mark 3 Munitions Booster: Attack Boost for Allied Ships (7000 range, +39% Bonus)
Light Starship: Attack Boost for Allied Ships (5000 range, +-61% Bonus)
Flagship: Attack Boost for Allied Ships (6000 range, +-31% Bonus)
Zenith Starship: Attack Boost for Allied Ships (5000 range, +0% Bonus)
Spire Starship: Attack Boost for Allied Ships (6000 range, +29% Bonus)
Yeah, for some reason, all of those boosts are labeled oddly.
