Why a 1960s missile conversion of Yavuz fails at the hull

How many Talos systems could Turkey fit into Yavuz in a 1960s refit?

The deep magazines could hold a fair number of Talos weapons, but the hull would be too old to justify the conversion.

Available internal volume does not make the modernization viable. Yavuz's deep magazines could hold a fair number of Talos weapons. By the 1960s, however, the First World War-era hull would be too old to justify such an extensive conversion. The ship's condition overwhelms any theoretical space calculation, leaving the missile count indeterminate.
