YD,
I must agree with MM that this thread starts with a false premise - that Typhoon can be navalised.
If you mean could it recover to and launch from a carrier reliably, the honest answer is that it can't. Not now, not ever, not at a cost and risk that our defence budget can stand. And even if it were, for some benighted reason, made to happen, the performance of the resulting aircraft would be a huge disappointment.
It's never been 'tested' and the navalized variant has never been 'designed'. Trust me (and others) on this.
Happy to converse via PM if you wish - I've posted plenty on this subject before - do a search, take a look and come back to me if I can help more.
Best Regards as ever
