Epsilon CLPS (SPRINT A) [JAXA]
Epsilon-2 (ERG) [JAXA]
The Epsilon (designated Advanced Solid Rocket during development) is replacement for the M-5 rocket.
The initial configuration, Epsilon, will feature the SRB-A3 Booster of the H-2A as first stage and the M-35 and KM-V2b stages of M-5 heritage as second and third stages. Optionally, a liquid fueled fourth stage (CLPS, Compact Liquid Propulsion Stage) can be carried. It will be capable to put about 1200 kg into low earth orbit (3 stage) or 450 kg into a sun synchronous orbit (4 stage). The focus in development will be on streamlining the launch procedures and reducing the costs.
Beginning with the second flight, it will be replaced by the improved Epsilon-2 (Enhanced Epsilon), which features a larger M-35 stage 2 and a modified stage 3, which both will have non-extending nozzles.
The new rocket had its maiden flight in 2013.
