As for money, this is why I asked the question about a Commonwealth space program. Britian would not have to foot the whole bill.
yeah if Canada, Australia, New Zealand and Great Britain had put there small-sized space budget together...
Canada had a Aerospace industry burst into bloom, until John Diefenbaker came to power and his "we don't need that million dollar monster" crap.
tallthinkev, if you wand a TL were Canada is part of Commonweath space program, get rid of John Diefenbaker. just crash his election campaign plane some were far north.
on Hardware,
in 1960 they GB had Blue Streak and Black Knight rockets and testing Lox/Lh2 engines
it's logical that first Commonwealth Launch rocket would be a Black Prince (Blue Streak/Black Knight/ solid stage) with Payload 600 kg in LEO
to demonstrate the possibly of launch rocket and bring Satellites in Earth orbit in 1960s.
Next phase would be put one Lox/Lh2 upper stage on Blue Streak. with payload of 2500 kg in LEO/ 300 kg to GEO
With two Lox/Lh2 upper stage on Blue Streak. we get 4000 kg in LEO and 600 kg to GEO
that version could start in early 1970s and could imply manned spaceflight.
