Foguete M-V

The M-V rocket, also called M-5 or Mu-5, was a Japanese solid-fuel rocket designed to launch scientific satellites. It was a member of the Mu family of rockets. The Institute of Space and Astronautical Science (ISAS) began developing the M-V in 1990 at a cost of 15 billion yen. It has three stages and is 30.7 meters high, 2.5 meters in diameter, and weighs about 140 tonnes (310,000 pounds). It was capable of launching a satellite weighing 1.8 tonnes (2 short tons) into an orbit as high as 250 km (155 miles).
There were concerns that the development of this three-stage solid fuel rocket, unusual for space exploration, was motivated by military concerns despite Japan’s non-nuclear policy. 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 a moments notice.
Lawmakers made national security arguments for keeping Japan's solid-fuel rocket technology alive after ISAS was merged into the Japan Aerospace Exploration Agency, which also has the H-IIA liquid-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 the threat from North Korea, it’s scary."
There are reports that the M-V design was modeled after the LG-118A Peacekeeper ICBM which has similar dimensions and payload, and is also a three-stage solid fuel rocket. The M-V design could be weaponised quickly although this would be politically difficult.
Pais serio é outra coisa
