The Vigilante was a decent kite, at least in the latter recon variant with increased range; but IIRC it didn't have a conventional bomb bay, but a novel affair where the nuclear load was 'extruded' out the rear (no comments
).
You could rework it for a conventional bomb bay. It would take time and money, but it could be done. Worst case you turn it into a fuel bay.
The wing pylons carried fuel tanks but I don't know about being wired for weapons.
It could be done.
Out of all the contenders I would opt for either the FIII or, a developed Buccaneer: more powerful engines, stretched airframe, new wings, and avionics. I have a drawing of this if anyones interested.
The Privateer!
I liked the Hustler, one of the most elegant looking bombers of its day, but I can see why it wore out with low level operations. Maybe over the Artic it wouldn't be such a problem if you're looking at a standoff role beyond range of Soviet shipborne sam's? I can just see a Swedish badged Hustler
Yep, the airframe just wasn't designed for low level ops. It would also give the Soviets fits about having super sonic bombers that close to the border. Alas to get the Swedes the planes they have to open up and admit that they are a part of NATO.
We could play around abit and give the hustler a decent bombay, internatal fuel load etc...that could fun. A more conventinal approach...maybe a FFVS licensened built B-58
What do you think about this deal.
In the late 1960s-early 70s the US wants to withdraw the B-58 from service due the airframes don't like the stress of the low level strikerole. Sweden decides to buy a number of surplus airframes and give them an upgrade with a new type om comformal pod/ bombay/fueltank, radar, ESM/ ECM and missile capailty with either 8x RB 04 - later rb 15 or 4x rb 08. They are also given capability to carry conventional bombs and some avionics upgrade.
Don't forget that they have the wing-root pylons. That's four 4 meter long, one tone munitions hard points.
