In fact, there was one test that had not yet been conducted.
Testing the armor protection of the Empire's navy battleships with the massive 460mm main guns of the "Saiyi."
Of course, it wouldn't actually involve subjecting the battleship to a beating; instead, identical armor steel plates would stand in for the battleship to test solely the armor protection.
To put it directly, it was a test of the ballistic performance of the 460mm naval guns at various ranges.
Initially, the Navy planned to use the assembled 460mm naval gun on the "Saiyi" for testing and even loaded several thousand tons of armor plates onto a landing ship, intending to transport them to a small island outside Long Sorrow Port and then assemble them into target for testing.
If that were indeed the case, the "Saiyi" could have survived for another ten days to half a month.
