The correct title of this article is #1 Ionium Jet. The substitution or omission of a # sign is because of technical restrictions.
#1 Ionium Jet
This is a mandatory ship part.
Weight 15
Max. Carriers 25 Pikmin
Location The Forest Navel

The #1 Ionium Jet is a ship part in Pikmin. It can be seen firing when the S.S. Dolphin takes off at the end of the day, preventing it from rotating. Due to this, it can be inferred that its purpose is for stabilization and traveling through deep space.

Collecting the Part


The #1 Ionium Jet with Olimar surrounding it.

In the Forest Navel take at least fifteen Blue Pikmin and go south from the landing site, there will be a large pool of water. Face to the right and go down the cliff with the pipe with Bomb Rocks inside of it and look to the right, it will be sitting in the water. Proceed to carry it back to the ship.


Discovery Notes

"I've found my #1 Ionium Jet! Unfortunately, this puts out a slightly odoriferous exhaust, but it does propel me to escape velocity in an instant. The stench is a small price to pay for such performance!"

Ship Log

"If this is damaged, I'll be in dire straits. I will have to run a system check as soon as I can."


  • In real life, ionium is a radioactive isotope of Thorium, with a mass number of 230.
  • The Number 1 Ionium Jet is one of the parts that can be seen on the outside of the ship.
  • It is similar in appearance and function to an RCS Thruster used in modern spacecraft.
