Aegis is not a free transfer of capability

Which surface-to-air and surface-to-surface missile systems would make the best transfer to another navy?

The recipient's maintenance infrastructure matters as much as the system's paper performance; Aegis can be excellent but punishing for a navy unable to sustain it.

The answer begins with the recipient navy's infrastructure rather than a catalogue of missile performance. Aegis can be highly capable, but it demands maintenance, repair, upgrades, skilled personnel, and a substantial supporting base. In a navy without that foundation, the system's burden can sap strength instead of creating a durable advantage. Some Soviet systems may be less effective on paper yet require somewhat less support, making them more useful in the recipient's actual circumstances. A successful transfer must match the weapon to the institution that will sustain it.
