A NATO Atlantic convoy escort in 1975

Which NATO warships would you assign to escort a US military convoy across the Atlantic in 1975?

The core would be Batch 3 Leanders and later Knox-class frigates, chosen for a strong period-appropriate ASW screen.

The answer works within the ships actually commissioned by 1975 rather than borrowing later capabilities. Batch 3 Leanders and later Knox-class frigates form the anti-submarine core. California-class nuclear cruisers add the strongest period-available air defense for a particularly important reinforcement convoy. The exercise illustrates how commissioning dates, threat sectors, and political responsibility shape a plausible Cold War escort force.
