[Star Wars] Did Sidious intend for Vader to be his successor? If not, what was his exit strategy as Emperor?

Also, did Vader intend to become Emperor after superseding Sidious some day? Or would he have wanted to continue in a military role while someone else became a figurehead as Emperor?

Darth Sidious' plan was to rule the galaxy at the head of the Galactic Empire. Ultimate power. Forever.

Sith Lords are the ambitious type.

For some background, Darth Sidious was trained under Darth Plagueis, a Sith Lord who focused on using the force to sustain and even create life. Unfortunately his skill at sustaining life with the use of the force could be undone through sufficient application of Sith lightning.

Darth Sidious was particularly fond of using Sith lightning, hence his master's undoing. But Sidious still learned of his former master's ability to use the force to manipulate life itself.

How do you think Anakin was able to survive his wounds long enough to be placed in a walking metal coffin? Darth Sidious was at his side, refusing to allow him to die and sustaining his life until the medical droids could place Anakin within his new body.
