As Japan's night fighter force was weak and the anti-aircraft batteries were less effective at night, LeMay also had most of the B-29s' defensive guns removed; by reducing the weight of the aircraft in this way they were able to carry more bombs.
Karena pasukan pesawat tempur malam Jepang lemah dan baterai anti pesawat kurang efektif pada malam hari, LeMay juga memerintahkan agar mencopot sebagian besar senjata defensif B-29; dengan mengurangi bobot pesawat melalui cara ini, mereka bisa mengangkut lebih banyak bom.
