How the Sea Harrier handled tanker and electronic-attack roles

Why did the Sea Harrier not receive dedicated buddy-tanker and electronic-attack variants?

It performed those functions through stores and pods, allowing a small carrier air group to adapt the same aircraft to multiple roles.

Sea Harriers could use buddy-refuelling stores, while electronic-attack equipment was carried in pods rather than assigned to a dedicated variant. That approach reflected the severe aircraft-type limits of small British carriers: the same basic airframe had to cover as many missions as possible. Modular stores traded some specialization for flexibility and avoided consuming scarce deck and hangar capacity with another unique aircraft type.
