Currently the germanGerman Luftwaffe has Panavia Tornados to deliver americanAmerican nuclear bombs in case of war. The bombers are getting older and are currently modernized. The germanGerman Luftwaffe also has Eurofighter Typhoons which are said to not be able to deliver nuclear weapons. Why is that so? (Same goes for the F-35 and the F-22)
AFAIK all that's needed for an aircraft to deliver nuclear bombs is
- theThe ability to actually carry the bombs, which probably conform to some standard "form factor".
- someSome special electronics for arming the bombs, which must be installed into the bomber - this probably also follows some standards.
Is that all? I seem to remember some special aerobatic maneuver the aircraft should be able to perform to allow the survival of the crew. Does that exist and is it a problem for modern fighter/bomber aircraftsaircraft?
