the B-58 was - born pretty, lived fast, died young.
How fitting for an epitaph in regards to the short career of the B-58 Hustler.
My own personal preferences for a WHIF based on the B-58 would be to do one as still active after having gone through a service life upgrade program of some kind later on to give it a new lease on life with improved avionics, and other bells and whistles such as additional pylons on the wings for countermeasures pods or defensive missiles such as AGM-45 Shrike, AGM-78 STARM, or AGM-69 SRAM to give it the ability to perform the SEAD mission for other strike aircraft.
If this were to be carried over to a WHIF in RAF markings, it would have to be something with a black underside since that color would look more suitable for an aircraft that is operating at high altitude and this would reduce the possibility of sunlight shining on the under side and creating points of illumination as it streaked across the skies at altitude. It would probably be armed with some kind of stand-off weapon based on a solid fuel weapon. Maybe a pair of Skybolt or the British Grand Slam II stand off missiles. This would give the Hustler the desired stand-off cabability and allow it to remain outside of air defenses to attack the targets.
For a Canadian B-158, I would hazard that it would carry the same ordnance as the USAF version since it would be simpler to maintain the weapons under US control until the warning order was received to issue the weapons to the end user and unlock the permissive action links that secured the weapons from unauthorized use. As far as painting, I would consider something in overall gray or NMF with the CAF style red/white stripe along the side of the aircraft that would be similar to that design found on the CF-101 Voodoo. Other camouflage options would be for an Avro Vulcan style green and gray top surface and an all black underside.
For something completely different, how about a Taiwan B-58 with a Taiwanese/American crew?
I was really hoping to see some better images of Steve Brooks' (SALT6) WHIF B-58 other than what he has provided on his web page. They are a bit fuzzy but you can make out some of the modifications that he has done to his. Steve, if you are reading this, how about some better images of your Hustler project?
I did have one other wild idea for a B-58 as a tactical strike aircraft with a semi-conventional weapon. Take your standard B-58 Hustler and replace the big fuel and bomb pod with the 22,000 pound Grand Slam bomb. Replacing the fuel and bomb pod with the Grand Slam would certainly limit the range but this would be made up for by topping off from tanker aircraft to and from the target. The question now is how to attach the Grand Slam to the underside of the Hustler and make it look plausible since the chain sections provided with the original bomb in the Lancaster is not replicated on the resin copy nor were any additional parts provided for mounting the weapon on an aircraft.
