A naval version of Typhoon was touted years ago. I did not know that it had surfaced again. There's an old adage that there has not been a single aircraft designed for land and adapted for sea that has been successful (speak to any Seafire pilot trying to put down that narrow track undercarriage on a pitching/rolling deck.)
There was also banter that the landing speed required would give Typhoon such a large AoA (and therfore nose attitude) that a camera would need to be fitted to the nose leg and projected onto one of the displays to enable the pilot to see the deck, obscured or restricted due by the approach AoA. It would be good to get a Typhoon driver to comment on this. If true, this would not be the optimum way to bring an aircraft onboard.
The JSF program is fine as long as politically we don't get ousted from the technology side of the deal. Nobody disputes that the aircraft will be fit for the stated purpose, the politics of source code access may be a tough issue.
The CVF design is set with the ability to retrofit catapults and cables as required by future platforms, fitted for but not with.
Good questions, keep being brave.
