And for comparison the late CF-105 (

and the Iroquois engine (of which there were 2)
dry thrust of 82.4 kN (8,400 kgp / 18,500 lbf) and an afterburning thrust of 115.8 kN (11,800 kgp / 26,000 lbf). (this number would seem to be based upon numbers from the early tests - expectations were that the production versions would hit at least 30,000 wet).
The Arrows were only ever flown with the J75 engine (same as the F-106). I do remember reading somewhere that the J75 was too long for the CF-105, so they left the
afterburned section off. This could be fairy tail, considering that the arrow did manage M1.5 during tests - would two J75s dry push a 55,000 lb aircraft to M1.5 ??
In any case, the J75 was also heavier than the Iroquois which made significant use of titanium....
So Iroquois engines would have provide 52K to 60K lbs of thrust to an aircraft with a maximum loaded weight of 69000lbs. I would expect that it should have been able to do the Concorde thing - reheat to get past the sonic barrier, and back to dry for "super cruise"..
Oh well......
