The competition heats up: Yesterday’s launch of Japan’s first commercial payload on its upgraded lower cost H-IIA rocket suggested that they are now a serious player in the competitive launch market. What the earlier articles didn’t tell me was the cost they charge to launch a payload on H-IIA.

This article today states that each launch costs 10 billion yen, which translates to about $80 million. That is about $10 million more than SpaceX charges for its Falcon 9, but is certainly cheaper than many other rocket companies. At this price they have a chance of grabbing some of the launch market, but to really compete they need to cut that cost even more, which the article suggests their next rocket will succeed in doing: “The government is developing a new core rocket named the H3, whose launches are expected to cost only about a half of the H2A.”

They do not say whether H3 will be reusable, but at $40 million per launch it will be the cheapest rocket on Earth. That it is government developed however makes me skeptical they will succeed. We shall see. What is clear, however, is that the competition is certainly encouraging the lowering of cost.

    They may launch for $40m if the Japanese government is willing to subsidize the program.

  • An excellent point. I suspect that is exactly what is going on. Rather than actually lower their costs, Japan is using government subsidies to make their rocket competitive.

    Such strategy can only work for so long. Eventually better technology and innovation wins out every time.
