^Well, ever company should do whatever they can. They shouldn't stop trying right? Or else they will forever lose the know-how to build fighter aircraft.
I'm glad Boeing is still trying to keep both their teen series production line going by offering relevant more features that might interest existing Eagle users.
Not sure if the Super Hornet can be configured for the same CWB. If Japan thinks they can do away with that, then they should be better off developing the Super Super Hornet.
Three points to note:
One, at the moment, there is no conformal weapons bay developed for the Super Hornet, nor is there any plans to do so (that I know of). Having said that any Japanese Air Self-Defense Force (JASDF) buy of new aircraft would be significant.
Two, I hope you are aware that the JASDF is the biggest foreign user of the F-15s in the world (according to Flight International, JASDF operates 154 F-15Js and 45 F-15DJs). Mitsubishi built the F-15Js in Japan, with the engines manufactured by Ishikawajima-Harima Heavy Industries under license from Pratt & Whitney.
Three, the Japan Defense Agency's (JDA) last development effort to further develop the F-16 into the Mitsubishi F-2 (its wing had 25% greater area, it had a tailplane assembly that was about 20% larger, wings that was of all-composite construction, with leading edges incorporating RAM, and AESA radar) for the JASDF proved to be horrendously expensive. The F-2 program turned into a classic Japanese defense-aerospace program, with development problems, long delays, and cost escalation. I'm not sure that they would continue in the same strategy for the sake of developing the capabilities of their industrial base. However, I'm sure they would like to maintain their industrial base. IMO, the Japanese would like to manufacture in Japan the fighter they choose to buy to replace their large legacy Phantom fleet. However, having said that, Japan may be be dragging their feet and waiting for the F-35 to become available.
But for non-JSF countries and current F-15 operators, this is quite attractive -- APG-81, DEWS, fly by wire, link 16, glass cockpit, JHMCS.
Yes, the proposed F-15SE's got quite a few features.
not sure if the 100M price tag is that much expensive than the rafale and EF, and if it is,
Let's not talk about pricing in such a vague manner - it can lead to unnecessary disagreement with members of our forum. Usually, you'll need to qualify the idea of price with 'flyaway price' or other such additional terms. Further the idea of price also needs to be tied to a reference year. Nothing is simple in pricing and the Silent Eagle is not a cheap plane to buy or maintain. Users need deep pockets and existing users have already invested in certain sunk costs, that's why, most of us feel that the Silent Eagle is targeted at existing Eagle users.
...those two others won't be as stealthy.
That's a point of contention that will not be resolved as NO targeted RCS figure (or customer requirement) has been released for the Silent Eagle by Boeing.
...Not sure how much weight countries put on the fact that the F-15 is a proven fighter.
A perfect combat record sound nice but let us not use a past record to predict future buying behaviour of countries. The issue is the platform's continued relevance to a country's threat matrix. We need to understand the intended role in a platform acquisition before we can discuss the merits of a particular platform for a specific role.
