TheM-Vrocket, also calledM-5orMu-5,was a Japanesesolid-fuel rocketdesigned to launchscientific satellites.It was a member of theMu familyofrockets.TheInstitute of Space and Astronautical Science(ISAS) began developing the M-V in 1990 at a cost of 15 billionyen.It has three stages and is 30.7 m (101 ft) high, 2.5 m (8 ft 2 in) indiameter,and weighs about 140,000 kg (310,000 lb). It was capable of launching a satellite weighing 1,800 kg (4,000 lb) into anorbitas high as 250 km (160 mi).

The first M-V rocket launched theHALCA radio astronomysatellite in 1997, and the second theNozomi Mars explorerin July 1998. The third rocket attempted to launch theAstro-E X-raysatellite on 10 February 2000 but failed. ISAS recovered from this setback and launchedHayabusato25143 Itokawain 2003. The following M-V launch was the scientificAstro-E2satellite, a replacement for Astro-E, which took place on 10 July 2005. The final launch was that of theHinode(SOLAR-B) spacecraft, along with theSSSat microsatand ananosatellite,HIT-SAT,on 22 September 2006.

Following program

A follow on to the M-V, called theEpsilon Rocket,^[7]features a lower 1.2 tonne LEO payload capability. The development aim is to reduce costs, primarily by using theH-IIAsolid rocket booster as the first stage and through shorter launch preparation time. Epsilon launches are intended to cost much less than the US$70 million launch cost of a M-V.^[8]

The first launch, of a small scientific satellite SPRINT-A (Hisaki), took place in September 2013. The initial launches will be of a two-stage version,^{[citation needed]}of Epsilon, with up to a 500 kilogram LEO payload capability.^[9]

Potential as an intercontinental ballistic missile

Solid fuel rockets are the design of choice for military applications as they can remain in storage for long periods, and then reliably launch at short notice.

Lawmakers made national security arguments for keeping Japan's solid-fuel rocket technology alive after ISAS was merged intoJAXA,which also has theH-IIAliquid-fuelled rocket, in 2003. The ISAS director of external affairs, Yasunori Matogawa, said, "It seems the hard-line national security proponents in parliament are increasing their influence, and they aren't getting much criticism... I think we’re moving into a very dangerous period. When you consider the current environment and thethreat from North Korea,it's scary ".^[10]

Toshiyuki Shikata, aTokyo Metropolitan Governmentadviser and former lieutenant general, claimed that part of the rationale for the fifth M-VHayabusamission was that the reentry and landing of its return capsule demonstrated "that Japan's ballistic missile capability is credible".^[11]

At a technical level the M-V design could be weaponised quickly (as anIntercontinental ballistic missile,since only payload and guidance have to be changed) although this would be politically unlikely.^[12]The M-V is comparable in performance to theLGM-118 PeacekeeperICBM.
