> Wait, if jets can melt steel, won't the engines melt off mid-flight?

Well... This is why optimally you should make jet engines from special alloys using lots of nickel, chromium and manganese. When Germans during WW2 switched to steel due to shortages of strategic materials service life of their Jumos fell to couple tens of hours at most. I don't know much about details of construction of Japanese engines, but I imagine they had even worse shortages than Germans, so... it actually makes sense to need materials for whole new engines for your planes after each sortie.
