Why Sea Harrier lacked specialist variants

Why did Sea Harrier never receive buddy-tanker or electronic-attack variants?

Britain relied on pods, while the United States operated separate specialist aircraft.

The British approach relied on pods rather than a dedicated electronic-attack Sea Harrier. That choice added mission equipment without funding and supporting a separate small subfleet. The United States could instead draw on specialist Intruder, Prowler, and later Growler families. Both arrangements reduced pressure to force tanker and electronic-attack roles into a purpose-built Sea Harrier variant.
