The P-1 is a spacecraft created by Toho that first appeared in the 1965 film, Invasion of Astro-Monster.

Invasion of Astro-Monster
The P-1 discovered Planet X on its voyage. It landed, and its crew found the Xiliens. After a talk with them, they returned to the ship to contact Earth about bringing Godzilla and Rodan. Once they were at the planet, the P-1 was remade by the Xiliens with an extra seat. The P-1 returned to Earth, where it was later destroyed by the Xiliens.
