About H3 Launch Vehicle
H3: To Space via Japan
This is the generation of space enterprise and innovation,
And with a new launch vehicle, we will unlock the skies―
Because nothing can go to space without one.
Through Japanese technology, reliability, and customizability,
Let us provide a launch vehicle through which
You can achieve your ambitious ventures.
In 2020, H3 will bring space ever-closer
And carry the world to space.
The H3 Launch Vehicle is a large-size next-generation launch vehicle whose maiden flight is scheduled in Japan Fiscal Year 2020 from the Tanegashima Space Center. H3 is under development to be a successor to the H-IIA Launch Vehicle, the current mainstay launch vehicle, in order to maintain Japan’s autonomous access to space.
Characteristics of H3 Launch Vehicle
1. Goal to be easy-to-use launch vehicle
Based on our investigation and prediction of what kind of launch needs will arise in 2020 and beyond, the H3 Launch Vehicle aims at achieving three factors namely, high flexibility, high reliability, and high cost performance.
We will offer an appropriate launch price and capability for each user’s needs by preparing various launch vehicle configurations. We can also respond promptly to customers’ requests for launching their payloads by reducing the launch preparation period.
By inheriting the high launch success rate of the H-IIA Launch Vehicle, H3 will also offer a reliable launch.
High cost performance
The launch service price will be lower compared to that of H-IIA
2. Most powerful launch with various launch configurations
We offer a selection of two types of fairings, two or three units for the first-stage engines (LE-9) and zero, two or four solid rocket boosters (SRB-3) to cope with various payload sizes and their orbits. We also set a high launch capability to the geostationary transfer orbit (GTO) that exceeds the capabilities of H-IIA and H-IIB.
