No. They might have played a small part to the delay in commissioning it, but
economics essentially killed the BLACK ARROW. Maybe if Scout wasn’t an
available option at the time, the program might have survived a bit longer, but
there was also the issue of payloads. After the successful launch of the X3
satellite the next payload (the subsequent X4) wasn’t ready for another 3-4
years and the BA needed to fly at least once a year for the companies involved
not to lose money – requiring gov subsidies to keep afloat.

I wonder if any of these issues caused them to abandon what was a fairly
successful launch vehicle.
