Which NATO platforms might perform better than expected?

Which ship, submarine, or aircraft type might be surprisingly effective in this scenario?

Sea Harriers could excel at chasing maritime reconnaissance aircraft, while Perry-class frigates would be useful, numerous ASW escorts.

The Sea Harrier need not defeat top Soviet fighters to matter. From an escort carrier it can intercept Bears and other aircraft trying to maintain contact with a convoy, breaking the reconnaissance link that enables later missile attacks. Post-Falklands improvements make the aircraft more capable than its reputation suggests in this limited mission. Perry-class frigates likewise bring helicopter and anti-submarine capacity in useful numbers, even if submarine commanders regard them as less prestigious targets. Both platforms overperform by matching the practical needs of convoy defense rather than by winning a duel with the enemy's most powerful system.
