When the designer sits down to build his aeroplane he does so to a specification. Part of that specification will include the structural strength (ultimate load), the design life and the planned Fatigue spectrum. In that Fatigue spectrum are things like the expected flight hours the expected number of take off and landings and the expected number of cycles of xx applications of various G. With all that defined he then makes his aeroplane to be able to meet that Fatigue spectrum. This then means the aeroplane will LAST that long provided the fatigue spectrum is accurate.

DT are not dealing with fatigue management and aircraft life. We are dealing with structural strength solely on a mission to mission basis. Pilots are given a recommended set of limits to fly to. Stay inside the limits no drama will occur. Exceed the limits and bending things may occur, grossly exceed the limits and structural failure may occur.

" ....And if our plane caring bombs and drop its in diving, stress forces increased" .... agreed and exactly that happens in the DT G Limit module.
