The most important part of a Harrier’s selling point
British air power in the Falklands Islands War in 1982 was limited to a handful of Harriers crammed on a pair of smallish carriers and a merchant ship, while the Argentines were able to throw all of their land-based A-4s and Mirage III/Vs at the British task force.
However, the Brits did manage to use their “jump jets” to good effect, including creating a FOB ashore.
A Harrier hide.

The San Carlos Forward Operating Base was variously called West Wittering, HMS Sheathbill and Sid’s Strip (after Squadron Leader Syd Morris)
As noted by Think Defence:
The FOB was variously called West Wittering, HMS Sheathbill and Sid’s Strip (after Squadron Leader Syd Morris) depending on what service you belonged to. The final FOB, operated by 11 Squadron RE and commanded by the RAF had a 260m runway, dispersal areas for four aircraft, a separate vertical landing pad and a redesigned and reinstalled bulk fuel installation that could store 18,000 Litres.
