Could a dreadnought carry Aegis and VLS?

How far could a dreadnought hull be upgraded with Aegis, helicopter facilities, and VLS?

Extensive reconstruction could make it possible, but gun blast, power demand, internal obstructions, and shipyard requirements make the practical case doubtful.

A dreadnought hull could accommodate modern weapons after sufficiently extensive reconstruction, but the practical case depends on which hull is available and how much of it is retained. Main-gun blast and shock threaten delicate electronics, while Aegis radar and computers require substantial electrical generation. Existing barbettes also complicate the placement of vertical-launch cells. USS Mississippi's postwar missile-test role provides an example of adapting a battleship for guided weapons, and Aegis proposals for the Iowa-class ships, Newport News, and Salem demonstrate the wider interest in such conversions. A refit on this scale needs dry docks, cranes, and supporting shipyard facilities. A navy with that industrial capacity can also build a new hull, which weakens the argument for an extreme reconstruction.
