mike-wsm,
Disagree - lacking in range, lacking in engines, lacking in weapons, lacking in stealth
Lacking in range - yeah, see where you're going with this one. However, the old argument that without HNS and AAR even the the F-35A is lacking in range; define in what context please.
Lacking in engines - it has one. F-16 has one; so did GR7/9; Mirage F1/2000 has one etc etc. Compared to the B-52 most other aircraft are 'lacking in engines'. Did you mean to say it is underpowered? At risk of crashing if that one engine fails and there isn't another to save the day? Again, define your context please so we can all understand your point.
Lacking in weapons - numbers of weapons that it can carry internally, externally, or what? Size of weapons is an issue as we well know but is it a lack of cleared weapon types you refer to? Context...
Lacking in stealth - oh really?! I disagree but, again, define (if you can on a public forum) why you make that statement so that we can all better understand.
