Non-PRO Japanese to English Art/Literary Cinema, Film, TV, Drama

Dear ProZ members,

I've found the following sentence in a cartoon. Some soldiers are considering the opportunity of performing a suicide attack with their highly evoluted aircrafts. One of them says:

我々の最終形態なら強度的な問題はない
(In our final form we won't have any problem of strenght.)

I was wondering which of the following options could be a correct translation for 強度的な問題.
1) Problem of strenght (having enough strenght to pierce the target)
2) Severe problem (generic translation)
3) Problem of durability (being sturdy enough in order to not go to pieces before reaching the target)

No. 1 seems the most common translation, while no. 2 is the most reasonable in the context, in my opinion.

Any hints? Thank you so much!
