Older Burkes received useful retrofits, including a stern flap credited in the quoted official figures with 5.3 percent lower fuel consumption and a 0.9-knot speed increase, plus computing and ballistic-missile-defence improvements. Those changes extended service life and capability without requiring a new class. The comparison with repeatedly rebuilding an old computer case makes the limit tangible: components can be replaced, but airflow, space, and structural assumptions eventually stop matching modern needs. Every internal cut and rearrangement can complicate the next change, so cumulative modernization creates engineering as well as budgetary limits.

Useful Burke retrofits meet a structural limit
Stern flaps and combat-system upgrades show the value of modernization, while a computer-case analogy explains why repeated rebuilding cannot substitute forever for a new hull.
