Launch Vehicle
The H3 Launch Vehicle is an expendable launch system in development in Japan. Each H3 booster configuration has a two-digit and a letter designation that indicates the features of that configuration. The first digit represents the number of LE-9 engines on the main stage, either "2" or "3". The second digit indicates the number of SRB-3 solid rocket boosters attached to the base of the rocket, and can be "0", "2" or "4". All layouts of solid boosters are symmetrical. The letter in the end shows the length of the payload fairing, either short "S" or long "L". For example, an H3-24L has two engines, four solid rocket boosters, and a long fairing, whereas an H3-30S has three engines, no solid rocket boosters, and a short fairing.

H3-24 is the launch vehicle record for catalog id 204.

This record currently resolves 6 launches (5 upcoming, 1 recent) for schedule and history context.
This record is built from the Launch Library 2 public catalog cache. The page keeps provider, pad, vehicle, astronaut, event, and location records separate from launch detail pages so source-backed facts stay easy to audit.
H3-24 is a catalog record with launch relationships. Use this page for entity context and linked launches for mission-specific timing, vehicle, and status details.
This page owns the catalog record. Collection pages own browsing, launch pages own mission timing and status, and the info hub explains the wider public-data surface.
