Why no vectored thrust capability?

IMHO, because it adds significantly to the cost and would be redundant to the integrated helmet and cross circle weapons.

Top speed on fighter aircraft hasn't changed since 1954, and instantaneous/continuous rate of turn will always be limited in manned aircraft to 12g.

Engine development is bound to continue to improve over time, but the significant technological edge will be electronics. They knew this going into Vietnam, but the technology wasn't ready to support it yet. The F-15/16/18 were designed to backfill into gaps.

Having said that, electronics can always be countered, while a ballistic 20mm cannon round up the tail can't be shrugged off. So I'll add an addendum to my original statement, Boeing wants to sell the F-22 and the USAF wants to buy it. Putting too many upgrades on the F-15 not only increases the price beyond the marketing target being discussed here, but it makes it a competitor (granted not the equal) to the F-22, thus making it tempting for Congress to cancel the F-22. I'm convinced this is the reason that the cross-circle weapons and smart helmets haven't yet been fielded in the current fleet.

I have nothing wise to add to the discussion. However, I wanted to say one thing.

Responses such as yours are the main reason I enjoy and use FreeRepublic so much. Your reply was well reasoned, well stated and concise. Thanks for your input.

"Boeing wants to sell the F-22 "



Boeing doesn't make the F-22. maybe some parts...
