Does the word 'superpower' require the article 'a'?

[Tanguatlay]

You don't have to have a superpower to save the planet.

Is "a" in the above optional?

Thanks.

Is "superpower" a noun or an adjective in your planned sentence?

[Tanguatlay]

A noun.

[Pljuchik]

'superpower' is an uncountable noun

[Pljuchik]

And how we use the noun "power" with "a"?

[Yankee]

You can use 'power' as a countable noun when it has this meaning, for example:

.

[Inga]

As a general rule, uncountable nouns are used without any article. The indefinite article is used with uncountable abstract nouns when they are modified by a descriptive attribute: A dull anger rose in his chest. There was a tenderness in his voice that moved her.

By the way, what Longman dictionary of contemporary English gives:
He hinted a bigger presence for the U.S. military in the Asian Pacific region where China is emerging as a superpower. But there is a tide here that may be irresistible even for a superpower. (countable)
So, it's not always the same as simply 'power'.
