Launch rate, or cadence, is not necessarily a fundamental metric for evaluating a launch provider, but it's an easy one.
From India Today's Sept. 18, 2018 article 6 months, 18 missions: ISRO sets new goals; ISRO is all set to complete 18 missions in a span of six months.
And now in a press release, ISRO Chairman K Sivan said, "We are going to have 18 missions in the next six months, virtually one launch every two weeks."
I read that as arithmetically being one launch every 10.7 days, but allowing for caution and modesty, it's extended to two weeks.
Among the higher cadence launch providers, are everyone's expectations for launch cadence for the next six moths or year roughly similar?, or would one provider stand out above the others according to this particular metric?
