Lucifer - re your reference, check the production link at the bottom
There was no two-seater as such; the RN used RAF T.4s, but these didn't have Sea Harrier systems and were used as conversion trainers.
Also RC, you can inform your boasting friend that the Sea Wolf is a SAM with no anti-surface capability (in fact the targeting computers would reject a surface target for safety as any ships within range would be friendly)
For further info the Anti-submarine 2 seat Sea Harrier was invented by Tom Clancy in The Hunt for Red October as a method for getting Jack Ryan into the area quickly; it would not be an effective weapon as it could not hover with the weight of 2 crew and dipping sonar.
