Wave-motion weapons change an Imperial fleet matchup

What happens if the Rebel Alliance receives a grand fleet of Space Battleship Yamato vessels after Yavin?

The panel generally favours the Yamato force under its proposed weapon-and-shield assumptions, while disputing how the settings interact and identifying recharge periods, Imperial fighters, and numerical attrition as possible counters.

The scenario adds roughly forty Space Battleship Yamato vessels, with the means to maintain them, to the Rebel Alliance after Yavin. The panel disagrees over how wave-motion shields, antimatter weapons, turbolasers, and Star Wars shields should interact across the two fictional settings. Arguments based on hull size alone compete with claims that the wave-motion gun could defeat much larger opponents. Firing that gun prevents a ship from jumping to warp and leaves its shield needing to recharge. An isolated vessel could therefore be induced to fire and attacked during the recovery period. Several ships operating together could cover one another through that interval. Imperial fighters and eventually overwhelming numbers remain possible counters. These battleships supplement the existing Rebel force, so their performance also depends on that wider force.
